Ethereum Classic

Ethereum Classic is an open, decentralized, and permissionless public blockchain, that aims to fulfill the original promise of Ethereum, as a platform where smart contracts are free from third-party interference. ETC prioritizes trust-minimization, network security, and integrity. All network upgrades are non-contentious with the aim to fix critical issues or to add value with newly proposed features; never to create new tokens, or to bail out flawed smart contracts and their interest groups.

Trolls have convinced some that *everything* should be stored on the same chain. Developers building apps on Bitcoin BCH need to consider that they may not always be able to push all data directly onto the *main* chain. Simple cash transactions should always take priority. (See BitDNS history)

Introducing Cryptosign.al — directly analyze Bitcoin / Ethereum prices and data using overlays, statistics, regression, and more.

Hey BitcoinMarkets,
Cryptosign.al is a tool for finding patterns in the prices / data of the top cryptocurrencies (right now just BTC and ETH). It gives you the ability to directly overlay charts, use common technical indicators, and visualize statistics including linear and polynomial regression, and correlation. Right now, the data is updated daily but I’m looking to make the periods smaller in the near future.
I’m a data scientist by trade and have been working on this site casually for the last 6 months, it’s been a ton of fun and I hope you guys find it useful. Some upcoming features I was thinking of: hourly (or finer) periods and live updates, more data sources (signals) to analyze, more advanced modeling features.
I would really enjoy hearing some feedback and any ideas you guys have (e.g., the next feature you want to see the most).
Also worth mentioning that I’ve been a long time member on these and other crypto subreddits but I’m separating my work/play accounts. Thanks for all your contributions and I hope this website reciprocates that at least a little bit.
Edit: Some people may be receiving a startup page for Nginx. I'll look into it, but PM if it's still an issue in a day or two, thanks :)

It's beginning to feel a lot like 2017. Some useful reminders and advice for new comers.

Hype and increasing prices will undoubtedly attract new investors, HODLers, and gamblers. Regardless of how long you've been in crypto, below are a few pieces of information (or reminders) you should consider.
  1. We're still early. Cryptocurrency, including bitcoin, is still in its infancy. Because of this, we will continue to see headlines of hacks, exchange closures, big name investors coming into the space, major institutional adoption, and everything in between. Until crypto is regulated (for better or worse) and even after, there will be bad actors attempting to steal your cryptocurrencies. To that end, think twice when hearing about 'deals' or investments that seem too good to be true. They probably are.
  2. Protection. I often see questions regarding the storage of cryptocurrencies. Not to oversimplify, but as a user, you have ~3 choices to store your cryptocurrency. In order of most secure to least secure:
    1. Cold Storage - From wikipedia: Cold storage refers to storing Bitcoins/Cryptos offline and spending without the private keys controlling them ever being online. This resists theft by hackers and malware, and is often a necessary security precaution especially dealing with large amounts of Bitcoin. If you aren't comfortable manually storing your private key, physical hardware wallets are your best alternative. When possible, buy direct from the manufacturer to avoid any tampering to your new device.
      1. https://trezor.io/
      2. https://www.ledger.com/
    2. Hot Wallets - From investopedia: The difference between a hot wallet and a cold wallet is that hot wallets are connected to the internet, while cold wallets are not. Hot wallets can be installed onto your mobile device and/or your web browser. Similar to cold storage, these hot wallets will 'store' your crypto and will be accessed to send/receive tokens, execute smart contracts, and conduct other transactions. There are many options to choose from, but MetaMask is as close to an industry standard as it comes, and the developer has recently implemented an ERC-20 token swap function. Again, download directly from the developer if you can.
      1. https://metamask.io/
    3. Exchanges - Exchanges certainly have their own purpose, most notably as an on and off ramp for your fiat currency (e.g., US Dollar, etc). However, when you read headlines like "Bitcoin Hacked for 10 million dollars!" what they usually mean is, a centralized exchange that holds users' cryptocurrencies was hacked and bitcoin was extracted from the exchange's storage. For this reason, exchanges are considered to be less safe than your Hot Wallet and Cold storage alternatives.
  3. Don't be greedy. This is easier said than done, and many veteran traders have learned this the hard way -- some still haven't learned. When prices are only going up, you're going to feel like a million bucks. But things dont go up forever. Ever. (Unless it's the Fed's balance sheet.. har har). Point being, it's okay to take profits along the way up. I guarantee you'll have an opportunity to re-buy those same tokens at a cheaper price, and you'll enjoy them even more the second time around.
  4. Don't spend more than you can afford. Hopefully this goes without saying, but the crypto space is extremely volatile. It is not uncommon to lose your entire investment with just one wrong token/ICO/scam. To that end; just use your common sense. It sounds easy, but when you're making money, sometimes it's hard to see the cliff at the end of the road.
  5. Keep learning. I joined the crypto space because I saw an opportunity to make money. It's been a wild ride, and I've learned a lot more than I've gained (from a monetary perspective). What i didn't expect to happen, was to open pandora's box when it comes to what Bitcoin (specifically) aimed to solve. My thirst for knowledge only expanded when I learned of the opportunity space Ethereum was trying to fill. Compound that with the immutability of blockchain technology, DeFi, smart contracts, data oracles, (and the list goes on); now I'm completely hooked. It's clear to me that blockchain will revolutionize the way we function on the global scale. But many are just now beginning to learn about bBitcoin, and we're ahead of the curve. Which leads me back to point number 1; we're still early.
Sorry for rambling on here; I'm sure more veteran HODLers have already X'd out of this post, which is fine. They likely don't need this information as they have learned these same tips along their own journeys. But for newcomers to the space, I wish I had this foundational knowledge from the get go. Don't be afraid to ask questions on this sub. With the recent implementation of MOON tokens (this is a whole 'nother topic), I've personally noticed more downvotes than normal. But awareness and understanding is critical to adoption, so don't be turned off if you don't get an answer to your questions immediately. There is a wealth of knowledge scattered across the internet, and still a lot of smart people on reddit who are willing to help.

[OC] Which front offices and agents are the 3 major newsbreakers connected to? I went through 6000+ tweets to find out!

If this sounds somewhat familiar, that's because I did a 2019-2020 version and posted it back in March.
In terms of changes from that post:
TL;DR
Tracked tweets of Woj, Shams and Haynes from 2018-2020 to see whether any of them report on a certain team or a certain agent's players more than their counterparts. Here is the main graph concerning a reporter's percentage of tweets per team separated into three periods (2019 season, 2020 offseason, 2020 season). Here is a separate graph with the Lakers and Warriors, because Haynes's percentages would skew the first graph.

During times like the NBA trade deadline or the lifting of the NBA free-agency moratorium, it’s not uncommon to see Twitter replies to (or Reddit comments about) star reporters reference their performance relative to others.
Woj is the preeminent scoop hound, but he is also notorious for writing hit pieces on LeBron (sources say it’s been widely rumoured that the reason for these is that Woj has always been unable to place a reliable source in LeBron’s camp). On the other end of the spectrum, it has been revealed that in exchange for exclusive intel on league memos and Pistons dealings, Woj wrote puff pieces on then-GM Joe Dumars (see above Kevin Draper link). Last summer, Woj was accused of being a Clippers shill on this very discussion board for noticeably driving the Kawhi Leonard free agency conversation towards the team.
This is the reason I undertook this project: to see whether some reporters have more sources in certain teams (and certain agencies) than other reporters.
First I’ll explain the methodology, then present the data with some initial comments.

Methodology

To make this manageable on myself, I limited myself to tracking the 3 major national reporters: Shams Charania of the Athletic, Chris Haynes of Yahoo Sports and the aforementioned Adrian Wojnarowski of ESPN.
The time period I initially tracked for was from January 1, 2020 to the end of the regular season March, but after finding a Twitter scraping tool on GitHub called Twint, I was able to easily retrieve all tweets since September 27, 2018. However, a month ago, Twitter closed their old API endpoints, and Twint ceased to work. I used vicinitas.io but the data loading became more time-consuming. Therefore, the tweets are up to the date of October 15 2020.
How I determined information was by manually parsing text tweets by the reporter (no retweets):
Now, I didn’t take every single text tweet:
Next, I had to assign possible teams to each tweet:
With all the methodology out of the way, here’s the data! (Here’s a link to a full Google Sheet)

Teams

Here's a graph of number of tweets per team per period, with the colours denoting reporter.
On a quick glance, here's which teams saw a significant period-over-period increase in number of tweets:
And here's which teams saw decreases over a period-by-period basis:
The problem with just using number of tweets is that it's not close on totals between Haynes vs. Woj or Shams. Here's a graph showing total number of tweets in each period for all three reporters. Haynes's most reported period doesn't even stack up to the least reported period of Woj or Shams.
Instead, let's look at percentage of tweets per team per period.
Now, you'll notice that there's two teams missing from the above graph: the Golden State Warriors and the Los Angeles Lakers. Here's the graphs for those two teams. As you can see, they would skew the previous graph far too much. During the 2019 NBA season, 27% of Chris Haynes's qualifying tweets could be possibly linked to the Warriors, and 14% of his qualifying tweets could be possibly linked to the Lakers.

Agents

Here's the top 10 agents in terms of number of potential tweets concerning their clients.
Agent Haynes Shams Woj Total
Rich Paul 15 28 24 67
Mark Bartelstein 4 16 30 50
Jeff Schwartz 3 10 25 38
Bill Duffy 2 13 14 29
Leon Rose 1 12 15 28
Aaron Mintz 2 9 15 26
Juan Perez 5 10 8 23
Aaron Goodwin 11 8 1 20
Steven Heumann 1 6 12 19
Sam Permut 1 13 5 19
Woj has the most tweets directly connected to agents by far. It wasn't uncommon to see "Player X signs deal with Team Y, Agent Z of Agency F tells ESPN." The agents that go to Woj (and some of their top clients):
One thing I found very intriguing: 15/16 of tweets concerning an Aaron Turner client were reported on by Shams. Turner is the head of Verus Basketball, whose clients include Terry Rozier, Victor Oladipo and Kevin Knox. Shams also reported more than 50% of news relating to clients of Sam Permut of Roc Nation. Permut is the current agent of Kyrie Irving, after Irving fired Jeff Wechsler near the beginning of the 2019 offseason. Permut also reps the Morris brothers and Trey Burke.
As for Chris Haynes, he doesn't really do much agent news (at least not at the level of Woj and Shams). However, he reported more than 50% of news relating to clients of Aaron Goodwin of Goodwin Sports Management, who reps Damian Lillard and DeMar DeRozan.
Here are the top 10 free agents from Forbes, along with their agent and who I predict will be the first/only one to break the news.
Player Agent Most Likely Reporter
Anthony Davis Rich Paul Too close to call, leaning Shams
Brandon Ingram Jeff Schwartz Woj
DeMar DeRozan Aaron Goodwin Haynes
Fred VanVleet Brian Jungreis Limited data
Andre Drummond Jeff Schwartz Woj
Montrezl Harrell Rich Paul Too close to call, leaning Shams
Gordon Hayward Mark Bartelstein Woj
Danilo Gallinari Michael Tellem Woj
Bogdan Bogdanovic Alexander Raskovic, Jason Ranne Limited data, but part of Wasserman, whose players are predominantly reported on by Woj
Davis Bertans Arturs Kalnitis Limited data
Thanks for reading! As always with this type of work, human error is not completely eliminated. If you think a tweet was mistakenly removed, feel free to drop me a line and I’ll try to explain my thought process on that specific tweet! Hope y’all enjoyed the research!

So if Po.et doesnt store the data directly to the bitcoin blockchain to reduce fees...

and it uses BitTorrent for this, then how is it still protected by the mining power of bitcoin?
Can someone please explain the technology behind using bittorrent instead of directly storing on the blockchain.
thanks

US OFAC issues advisory: ransom payments for ransomware may involve felony charges and personal civil liability for staff.

Relevant Excerpt:
Under the authority of the International Emergency Economic Powers Act (IEEPA) or the Trading with the Enemy Act (TWEA),9 U.S. persons are generally prohibited from engaging in transactions, directly or indirectly, with individuals or entities (“persons”) on OFAC’s Specially Designated Nationals and Blocked Persons List (SDN List), other blocked persons, and those covered by comprehensive country or region embargoes (e.g., Cuba, the Crimea region of Ukraine, Iran, North Korea, and Syria). Additionally, any transaction that causes a violation under IEEPA, including transactions by a non-U.S. person which causes a U.S. person to violate any IEEPA-based sanctions, is also prohibited. U.S. persons, wherever located, are also generally prohibited from facilitating actions of non-U.S. persons, which could not be directly performed by U.S. persons due to U.S. sanctions regulations. OFAC may impose civil penalties for sanctions violations based on strict liability, meaning that a person subject to U.S. jurisdiction may be held civilly liable even if it did not know or have reason to know it was engaging in a transaction with a person that is prohibited under sanctions laws and regulations administered by OFAC.
Sauce Here: https://home.treasury.gov/system/files/126/ofac_ransomware_advisory_10012020_1.pdf
OFAC Sanctions list here: https://sanctionssearch.ofac.treas.gov/
Analysis: Both TWEA and IEEPA carries Criminal and Civil penalties, so under these acts they can fine the company, fine staff directly, or press criminal charges. We know the US Government as part of both the 5 eyes agreements and domestic bank monitoring programs under FACTA monitors all international wire transfers. Bitcoin and other cryptocurrencies generally leave a paper trail that can be traced back to who purchased the currency.
What I expect to start happening here is most CFO's are going to write off the cost of the ransom as a tax deduction which tips off the IRS that a ransom of some kind was paid. I expect the next step is the IRS is going to start asking for additional proof of payment and additional information about the cases. That puts CFO's in a bind, because I expect both the IRS, and federal courts, won't let it fly that you didn't know who you were paying money to under the TWEA. They'll sit on the data, and when eventually an APT Group gets compromised, they'll trace the payments back via said tax records. At that point, if your org paid under this, that data gets used to open up a search warrant and then they rip you a new one especially if the payment was substantial.
The bigger issue here is it opens up tremendous liability for security services firms and insurers who pay ransoms on behalf of clients or advise clients to pay ransoms.
Now is a good time to review your backup strategy and ensure you have tested backups that are isolated from your infrastructure.
For those of you with your hands tied behind your back, now is a good time to gently remind your management staff, and especially the CFO if you have their ear, that they cannot rely on the renound cryptographic competence of our eastern european bretheren, and that their worst-case risk is a determined remote attacker and adversary of the US infecting your network, destroying the data while making it look like a ransomware attack, selling you worthless encryption keys to fund their operation before flaunting the fact they took you for a fool with a press release taking credit for the attack to tip off state government you paid them in order to further disrupt the company operations via putting your talented technical staff or c-suite staff in handcuffs and injuring your PR.
To those of you in the business who are afraid of being scapegoated or in a tenuous situation, getchu some evidence tape and some tags, some vanilla envelopes and a glue stick. Print 2 copies, put one copy in a folder, seal it with evidence tape and a tag, then use your handy glue stick to adhere the other vanilla folder to its back and put the 2nd copy in so you can review the paperwork without breaking the evidence seal and shove that sucker in a fire proof safe or safety deposit box. Also, Mailstore home is free.
TL;DR: If your company is attacked by ransomware, tell the management only facts of the occurance you know, what you can and cannot do for them, and don't advise them of anything upto and including getting a security services firm involved. I wouldn't even tell them paying the ransom might work. If you're going to have a verbal conversation, make it a one-on-one.
Happy Saturday all!

I think the virtual assistant position I’ve taken is a scam but I’m not sure what they’re trying to do...

I worked as a virtual assistant in the past, I found the client on a freelance platform, but then we agreed on a contract off the platform. I worked with him for 3 years and it was great, he didn’t need help anymore so I started looking for a new client.
I found a new client to virtually assist (found on freelance website) and didn’t think anything of it when we moved off the website. He sent me a contract... it seemed a little too good to be true. $400 a week 2-3 hours of work per day Mon-Fri. I found his legit looking manufacturing business website online...so I signed it anyway, emailed with his HR giving them my direct deposit info for payment. I completed the first week of “work” which has consisted of: Making excel spreadsheets with no data just things like expense, unit price, total units, total price... 14 different ones. Sending a “memo” to “clients”with totally made up looking email addresses. Pricing architecture/industrial equipment online and sending links.
He asked me to make him an email address. Gmail. His name follows by his companies name but that was taken (weird) he told me to just add numbers to it. Then he asked if I was set up for Bitcoin on cashapp... I wasn’t & i know nothing about Bitcoin but I set up for verification anyway (still pending) but he didn’t ask for my cashapp information... I’ve spoken with him on the phone a couple times about random stuff, including getting paid which he said was sent out Friday so I should be receiving it Monday or Tuesday.... which I doubt. My husband was VERY suspicious so we transferred all the money out of the account (it’s my personal account just used for freelance work payments not our actual finances) We called the number on his business webpage and it’s disconnected.
Is this a scam & if so what are they doing? And how much have I compromised myself by giving them my name, address, and direct deposit information?
I’m supposed to contact him Monday to continue the work.

Comparison between Avalanche, Cosmos and Polkadot

Comparison between Avalanche, Cosmos and Polkadot
Reposting after was mistakenly removed by mods (since resolved - Thanks)
A frequent question I see being asked is how Cosmos, Polkadot and Avalanche compare? Whilst there are similarities there are also a lot of differences. This article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important.
For better formatting see https://medium.com/ava-hub/comparison-between-avalanche-cosmos-and-polkadot-a2a98f46c03b
https://preview.redd.it/e8s7dj3ivpq51.png?width=428&format=png&auto=webp&s=5d0463462702637118c7527ebf96e91f4a80b290

Overview

Cosmos

Cosmos is a heterogeneous network of many independent parallel blockchains, each powered by classical BFT consensus algorithms like Tendermint. Developers can easily build custom application specific blockchains, called Zones, through the Cosmos SDK framework. These Zones connect to Hubs, which are specifically designed to connect zones together.
The vision of Cosmos is to have thousands of Zones and Hubs that are Interoperable through the Inter-Blockchain Communication Protocol (IBC). Cosmos can also connect to other systems through peg zones, which are specifically designed zones that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. Cosmos does not use Sharding with each Zone and Hub being sovereign with their own validator set.
For a more in-depth look at Cosmos and provide more reference to points made in this article, please see my three part series — Part One, Part Two, Part Three
(There's a youtube video with a quick video overview of Cosmos on the medium article - https://medium.com/ava-hub/comparison-between-avalanche-cosmos-and-polkadot-a2a98f46c03b)

Polkadot

Polkadot is a heterogeneous blockchain protocol that connects multiple specialised blockchains into one unified network. It achieves scalability through a sharding infrastructure with multiple blockchains running in parallel, called parachains, that connect to a central chain called the Relay Chain. Developers can easily build custom application specific parachains through the Substrate development framework.
The relay chain validates the state transition of connected parachains, providing shared state across the entire ecosystem. If the Relay Chain must revert for any reason, then all of the parachains would also revert. This is to ensure that the validity of the entire system can persist, and no individual part is corruptible. The shared state makes it so that the trust assumptions when using parachains are only those of the Relay Chain validator set, and no other. Interoperability is enabled between parachains through Cross-Chain Message Passing (XCMP) protocol and is also possible to connect to other systems through bridges, which are specifically designed parachains or parathreads that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. The hope is to have 100 parachains connect to the relay chain.
For a more in-depth look at Polkadot and provide more reference to points made in this article, please see my three part series — Part One, Part Two, Part Three
(There's a youtube video with a quick video overview of Polkadot on the medium article - https://medium.com/ava-hub/comparison-between-avalanche-cosmos-and-polkadot-a2a98f46c03b)

Avalanche

Avalanche is a platform of platforms, ultimately consisting of thousands of subnets to form a heterogeneous interoperable network of many blockchains, that takes advantage of the revolutionary Avalanche Consensus protocols to provide a secure, globally distributed, interoperable and trustless framework offering unprecedented decentralisation whilst being able to comply with regulatory requirements.
Avalanche allows anyone to create their own tailor-made application specific blockchains, supporting multiple custom virtual machines such as EVM and WASM and written in popular languages like Go (with others coming in the future) rather than lightly used, poorly-understood languages like Solidity. This virtual machine can then be deployed on a custom blockchain network, called a subnet, which consist of a dynamic set of validators working together to achieve consensus on the state of a set of many blockchains where complex rulesets can be configured to meet regulatory compliance.
Avalanche was built with serving financial markets in mind. It has native support for easily creating and trading digital smart assets with complex custom rule sets that define how the asset is handled and traded to ensure regulatory compliance can be met. Interoperability is enabled between blockchains within a subnet as well as between subnets. Like Cosmos and Polkadot, Avalanche is also able to connect to other systems through bridges, through custom virtual machines made to interact with another ecosystem such as Ethereum and Bitcoin.

A frequent question I see being asked is how Cosmos, Polkadot and Avalanche compare? Whilst there are similarities there are also a lot of differences. This article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important. For a more in-depth view I recommend reading the articles for each of the projects linked above and coming to your own conclusions. I want to stress that it’s not a case of one platform being the killer of all other platforms, far from it. There won’t be one platform to rule them all, and too often the tribalism has plagued this space. Blockchains are going to completely revolutionise most industries and have a profound effect on the world we know today. It’s still very early in this space with most adoption limited to speculation and trading mainly due to the limitations of Blockchain and current iteration of Ethereum, which all three of these platforms hope to address. For those who just want a quick summary see the image at the bottom of the article. With that said let’s have a look

Scalability

Cosmos

Each Zone and Hub in Cosmos is capable of up to around 1000 transactions per second with bandwidth being the bottleneck in consensus. Cosmos aims to have thousands of Zones and Hubs all connected through IBC. There is no limit on the number of Zones / Hubs that can be created

Polkadot

Parachains in Polkadot are also capable of up to around 1500 transactions per second. A portion of the parachain slots on the Relay Chain will be designated as part of the parathread pool, the performance of a parachain is split between many parathreads offering lower performance and compete amongst themselves in a per-block auction to have their transactions included in the next relay chain block. The number of parachains is limited by the number of validators on the relay chain, they hope to be able to achieve 100 parachains.

Avalanche

Avalanche is capable of around 4500 transactions per second per subnet, this is based on modest hardware requirements to ensure maximum decentralisation of just 2 CPU cores and 4 GB of Memory and with a validator size of over 2,000 nodes. Performance is CPU-bound and if higher performance is required then more specialised subnets can be created with higher minimum requirements to be able to achieve 10,000 tps+ in a subnet. Avalanche aims to have thousands of subnets (each with multiple virtual machines / blockchains) all interoperable with each other. There is no limit on the number of Subnets that can be created.

Results

All three platforms offer vastly superior performance to the likes of Bitcoin and Ethereum 1.0. Avalanche with its higher transactions per second, no limit on the number of subnets / blockchains that can be created and the consensus can scale to potentially millions of validators all participating in consensus scores ✅✅✅. Polkadot claims to offer more tps than cosmos, but is limited to the number of parachains (around 100) whereas with Cosmos there is no limit on the number of hubs / zones that can be created. Cosmos is limited to a fairly small validator size of around 200 before performance degrades whereas Polkadot hopes to be able to reach 1000 validators in the relay chain (albeit only a small number of validators are assigned to each parachain). Thus Cosmos and Polkadot scores ✅✅

Decentralisation

Cosmos

Tendermint consensus is limited to around 200 validators before performance starts to degrade. Whilst there is the Cosmos Hub it is one of many hubs in the network and there is no central hub or limit on the number of zones / hubs that can be created.

Polkadot

Polkadot has 1000 validators in the relay chain and these are split up into a small number that validate each parachain (minimum of 14). The relay chain is a central point of failure as all parachains connect to it and the number of parachains is limited depending on the number of validators (they hope to achieve 100 parachains). Due to the limited number of parachain slots available, significant sums of DOT will need to be purchased to win an auction to lease the slot for up to 24 months at a time. Thus likely to lead to only those with enough funds to secure a parachain slot. Parathreads are however an alternative for those that require less and more varied performance for those that can’t secure a parachain slot.

Avalanche

Avalanche consensus scan scale to tens of thousands of validators, even potentially millions of validators all participating in consensus through repeated sub-sampling. The more validators, the faster the network becomes as the load is split between them. There are modest hardware requirements so anyone can run a node and there is no limit on the number of subnets / virtual machines that can be created.

Results

Avalanche offers unparalleled decentralisation using its revolutionary consensus protocols that can scale to millions of validators all participating in consensus at the same time. There is no limit to the number of subnets and virtual machines that can be created, and they can be created by anyone for a small fee, it scores ✅✅✅. Cosmos is limited to 200 validators but no limit on the number of zones / hubs that can be created, which anyone can create and scores ✅✅. Polkadot hopes to accommodate 1000 validators in the relay chain (albeit these are split amongst each of the parachains). The number of parachains is limited and maybe cost prohibitive for many and the relay chain is a ultimately a single point of failure. Whilst definitely not saying it’s centralised and it is more decentralised than many others, just in comparison between the three, it scores ✅
https://preview.redd.it/ckfamee0wpq51.png?width=1000&format=png&auto=webp&s=c4355f145d821fabf7785e238dbc96a5f5ce2846

Latency

Cosmos

Tendermint consensus used in Cosmos reaches finality within 6 seconds. Cosmos consists of many Zones and Hubs that connect to each other. Communication between 2 zones could pass through many hubs along the way, thus also can contribute to latency times depending on the path taken as explained in part two of the articles on Cosmos. It doesn’t need to wait for an extended period of time with risk of rollbacks.

Polkadot

Polkadot provides a Hybrid consensus protocol consisting of Block producing protocol, BABE, and then a finality gadget called GRANDPA that works to agree on a chain, out of many possible forks, by following some simpler fork choice rule. Rather than voting on every block, instead it reaches agreements on chains. As soon as more than 2/3 of validators attest to a chain containing a certain block, all blocks leading up to that one are finalized at once.
If an invalid block is detected after it has been finalised then the relay chain would need to be reverted along with every parachain. This is particularly important when connecting to external blockchains as those don’t share the state of the relay chain and thus can’t be rolled back. The longer the time period, the more secure the network is, as there is more time for additional checks to be performed and reported but at the expense of finality. Finality is reached within 60 seconds between parachains but for external ecosystems like Ethereum their state obviously can’t be rolled back like a parachain and so finality will need to be much longer (60 minutes was suggested in the whitepaper) and discussed in more detail in part three

Avalanche

Avalanche consensus achieves finality within 3 seconds, with most happening sub 1 second, immutable and completely irreversible. Any subnet can connect directly to another without having to go through multiple hops and any VM can talk to another VM within the same subnet as well as external subnets. It doesn’t need to wait for an extended period of time with risk of rollbacks.

Results

With regards to performance far too much emphasis is just put on tps as a metric, the other equally important metric, if not more important with regards to finance is latency. Throughput measures the amount of data at any given time that it can handle whereas latency is the amount of time it takes to perform an action. It’s pointless saying you can process more transactions per second than VISA when it takes 60 seconds for a transaction to complete. Low latency also greatly increases general usability and customer satisfaction, nowadays everyone expects card payments, online payments to happen instantly. Avalanche achieves the best results scoring ✅✅✅, Cosmos with comes in second with 6 second finality ✅✅ and Polkadot with 60 second finality (which may be 60 minutes for external blockchains) scores ✅
https://preview.redd.it/kzup5x42wpq51.png?width=1000&format=png&auto=webp&s=320eb4c25dc4fc0f443a7a2f7ff09567871648cd

Shared Security

Cosmos

Every Zone and Hub in Cosmos has their own validator set and different trust assumptions. Cosmos are researching a shared security model where a Hub can validate the state of connected zones for a fee but not released yet. Once available this will make shared security optional rather than mandatory.

Polkadot

Shared Security is mandatory with Polkadot which uses a Shared State infrastructure between the Relay Chain and all of the connected parachains. If the Relay Chain must revert for any reason, then all of the parachains would also revert. Every parachain makes the same trust assumptions, and as such the relay chain validates state transition and enables seamless interoperability between them. In return for this benefit, they have to purchase DOT and win an auction for one of the available parachain slots.
However, parachains can’t just rely on the relay chain for their security, they will also need to implement censorship resistance measures and utilise proof of work / proof of stake for each parachain as well as discussed in part three, thus parachains can’t just rely on the security of the relay chain, they need to ensure sybil resistance mechanisms using POW and POS are implemented on the parachain as well.

Avalanche

A subnet in Avalanche consists of a dynamic set of validators working together to achieve consensus on the state of a set of many blockchains where complex rulesets can be configured to meet regulatory compliance. So unlike in Cosmos where each zone / hub has their own validators, A subnet can validate a single or many virtual machines / blockchains with a single validator set. Shared security is optional

Results

Shared security is mandatory in polkadot and a key design decision in its infrastructure. The relay chain validates the state transition of all connected parachains and thus scores ✅✅✅. Subnets in Avalanche can validate state of either a single or many virtual machines. Each subnet can have their own token and shares a validator set, where complex rulesets can be configured to meet regulatory compliance. It scores ✅ ✅. Every Zone and Hub in cosmos has their own validator set / token but research is underway to have the hub validate the state transition of connected zones, but as this is still early in the research phase scores ✅ for now.

Current Adoption

Cosmos

The Cosmos project started in 2016 with an ICO held in April 2017. There are currently around 50 projects building on the Cosmos SDK with a full list can be seen here and filtering for Cosmos SDK . Not all of the projects will necessarily connect using native cosmos sdk and IBC and some have forked parts of the Cosmos SDK and utilise the tendermint consensus such as Binance Chain but have said they will connect in the future.

Polkadot

The Polkadot project started in 2016 with an ICO held in October 2017. There are currently around 70 projects building on Substrate and a full list can be seen here and filtering for Substrate Based. Like with Cosmos not all projects built using substrate will necessarily connect to Polkadot and parachains or parathreads aren’t currently implemented in either the Live or Test network (Kusama) as of the time of this writing.

Avalanche

Avalanche in comparison started much later with Ava Labs being founded in 2018. Avalanche held it’s ICO in July 2020. Due to lot shorter time it has been in development, the number of projects confirmed are smaller with around 14 projects currently building on Avalanche. Due to the customisability of the platform though, many virtual machines can be used within a subnet making the process incredibly easy to port projects over. As an example, it will launch with the Ethereum Virtual Machine which enables byte for byte compatibility and all the tooling like Metamask, Truffle etc. will work, so projects can easily move over to benefit from the performance, decentralisation and low gas fees offered. In the future Cosmos and Substrate virtual machines could be implemented on Avalanche.

Results

Whilst it’s still early for all 3 projects (and the entire blockchain space as a whole), there is currently more projects confirmed to be building on Cosmos and Polkadot, mostly due to their longer time in development. Whilst Cosmos has fewer projects, zones are implemented compared to Polkadot which doesn’t currently have parachains. IBC to connect zones and hubs together is due to launch Q2 2021, thus both score ✅✅✅. Avalanche has been in development for a lot shorter time period, but is launching with an impressive feature set right from the start with ability to create subnets, VMs, assets, NFTs, permissioned and permissionless blockchains, cross chain atomic swaps within a subnet, smart contracts, bridge to Ethereum etc. Applications can easily port over from other platforms and use all the existing tooling such as Metamask / Truffle etc but benefit from the performance, decentralisation and low gas fees offered. Currently though just based on the number of projects in comparison it scores ✅.
https://preview.redd.it/4zpi6s85wpq51.png?width=1000&format=png&auto=webp&s=e91ade1a86a5d50f4976f3b23a46e9287b08e373

Enterprise Adoption

Cosmos

Cosmos enables permissioned and permissionless zones which can connect to each other with the ability to have full control over who validates the blockchain. For permissionless zones each zone / hub can have their own token and they are in control who validates.

Polkadot

With polkadot the state transition is performed by a small randomly selected assigned group of validators from the relay chain plus with the possibility that state is rolled back if an invalid transaction of any of the other parachains is found. This may pose a problem for enterprises that need complete control over who performs validation for regulatory reasons. In addition due to the limited number of parachain slots available Enterprises would have to acquire and lock up large amounts of a highly volatile asset (DOT) and have the possibility that they are outbid in future auctions and find they no longer can have their parachain validated and parathreads don’t provide the guaranteed performance requirements for the application to function.

Avalanche

Avalanche enables permissioned and permissionless subnets and complex rulesets can be configured to meet regulatory compliance. For example a subnet can be created where its mandatory that all validators are from a certain legal jurisdiction, or they hold a specific license and regulated by the SEC etc. Subnets are also able to scale to tens of thousands of validators, and even potentially millions of nodes, all participating in consensus so every enterprise can run their own node rather than only a small amount. Enterprises don’t have to hold large amounts of a highly volatile asset, but instead pay a fee in AVAX for the creation of the subnets and blockchains which is burnt.

Results

Avalanche provides the customisability to run private permissioned blockchains as well as permissionless where the enterprise is in control over who validates the blockchain, with the ability to use complex rulesets to meet regulatory compliance, thus scores ✅✅✅. Cosmos is also able to run permissioned and permissionless zones / hubs so enterprises have full control over who validates a blockchain and scores ✅✅. Polkadot requires locking up large amounts of a highly volatile asset with the possibility of being outbid by competitors and being unable to run the application if the guaranteed performance is required and having to migrate away. The relay chain validates the state transition and can roll back the parachain should an invalid block be detected on another parachain, thus scores ✅.
https://preview.redd.it/li5jy6u6wpq51.png?width=1000&format=png&auto=webp&s=e2a95f1f88e5efbcf9e23c789ae0f002c8eb73fc

Interoperability

Cosmos

Cosmos will connect Hubs and Zones together through its IBC protocol (due to release in Q1 2020). Connecting to blockchains outside of the Cosmos ecosystem would either require the connected blockchain to fork their code to implement IBC or more likely a custom “Peg Zone” will be created specific to work with a particular blockchain it’s trying to bridge to such as Ethereum etc. Each Zone and Hub has different trust levels and connectivity between 2 zones can have different trust depending on which path it takes (this is discussed more in this article). Finality time is low at 6 seconds, but depending on the number of hops, this can increase significantly.

Polkadot

Polkadot’s shared state means each parachain that connects shares the same trust assumptions, of the relay chain validators and that if one blockchain needs to be reverted, all of them will need to be reverted. Interoperability is enabled between parachains through Cross-Chain Message Passing (XCMP) protocol and is also possible to connect to other systems through bridges, which are specifically designed parachains or parathreads that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. Finality time between parachains is around 60 seconds, but longer will be needed (initial figures of 60 minutes in the whitepaper) for connecting to external blockchains. Thus limiting the appeal of connecting two external ecosystems together through Polkadot. Polkadot is also limited in the number of Parachain slots available, thus limiting the amount of blockchains that can be bridged. Parathreads could be used for lower performance bridges, but the speed of future blockchains is only going to increase.

Avalanche

A subnet can validate multiple virtual machines / blockchains and all blockchains within a subnet share the same trust assumptions / validator set, enabling cross chain interoperability. Interoperability is also possible between any other subnet, with the hope Avalanche will consist of thousands of subnets. Each subnet may have a different trust level, but as the primary network consists of all validators then this can be used as a source of trust if required. As Avalanche supports many virtual machines, bridges to other ecosystems are created by running the connected virtual machine. There will be an Ethereum bridge using the EVM shortly after mainnet. Finality time is much faster at sub 3 seconds (with most happening under 1 second) with no chance of rolling back so more appealing when connecting to external blockchains.

Results

All 3 systems are able to perform interoperability within their ecosystem and transfer assets as well as data, as well as use bridges to connect to external blockchains. Cosmos has different trust levels between its zones and hubs and can create issues depending on which path it takes and additional latency added. Polkadot provides the same trust assumptions for all connected parachains but has long finality and limited number of parachain slots available. Avalanche provides the same trust assumptions for all blockchains within a subnet, and different trust levels between subnets. However due to the primary network consisting of all validators it can be used for trust. Avalanche also has a much faster finality time with no limitation on the number of blockchains / subnets / bridges that can be created. Overall all three blockchains excel with interoperability within their ecosystem and each score ✅✅.

Tokenomics

Cosmos

The ATOM token is the native token for the Cosmos Hub. It is commonly mistaken by people that think it’s the token used throughout the cosmos ecosystem, whereas it’s just used for one of many hubs in Cosmos, each with their own token. Currently ATOM has little utility as IBC isn’t released and has no connections to other zones / hubs. Once IBC is released zones may prefer to connect to a different hub instead and so ATOM is not used. ATOM isn’t a fixed capped supply token and supply will continuously increase with a yearly inflation of around 10% depending on the % staked. The current market cap for ATOM as of the time of this writing is $1 Billion with 203 million circulating supply. Rewards can be earnt through staking to offset the dilution caused by inflation. Delegators can also get slashed and lose a portion of their ATOM should the validator misbehave.

Polkadot

Polkadot’s native token is DOT and it’s used to secure the Relay Chain. Each parachain needs to acquire sufficient DOT to win an auction on an available parachain lease period of up to 24 months at a time. Parathreads have a fixed fee for registration that would realistically be much lower than the cost of acquiring a parachain slot and compete with other parathreads in a per-block auction to have their transactions included in the next relay chain block. DOT isn’t a fixed capped supply token and supply will continuously increase with a yearly inflation of around 10% depending on the % staked. The current market cap for DOT as of the time of this writing is $4.4 Billion with 852 million circulating supply. Delegators can also get slashed and lose their DOT (potentially 100% of their DOT for serious attacks) should the validator misbehave.

Avalanche

AVAX is the native token for the primary network in Avalanche. Every validator of any subnet also has to validate the primary network and stake a minimum of 2000 AVAX. There is no limit to the number of validators like other consensus methods then this can cater for tens of thousands even potentially millions of validators. As every validator validates the primary network, this can be a source of trust for interoperability between subnets as well as connecting to other ecosystems, thus increasing amount of transaction fees of AVAX. There is no slashing in Avalanche, so there is no risk to lose your AVAX when selecting a validator, instead rewards earnt for staking can be slashed should the validator misbehave. Because Avalanche doesn’t have direct slashing, it is technically possible for someone to both stake AND deliver tokens for something like a flash loan, under the invariant that all tokens that are staked are returned, thus being able to make profit with staked tokens outside of staking itself.
There will also be a separate subnet for Athereum which is a ‘spoon,’ or friendly fork, of Ethereum, which benefits from the Avalanche consensus protocol and applications in the Ethereum ecosystem. It’s native token ATH will be airdropped to ETH holders as well as potentially AVAX holders as well. This can be done for other blockchains as well.
Transaction fees on the primary network for all 3 of the blockchains as well as subscription fees for creating a subnet and blockchain are paid in AVAX and are burnt, creating deflationary pressure. AVAX is a fixed capped supply of 720 million tokens, creating scarcity rather than an unlimited supply which continuously increase of tokens at a compounded rate each year like others. Initially there will be 360 tokens minted at Mainnet with vesting periods between 1 and 10 years, with tokens gradually unlocking each quarter. The Circulating supply is 24.5 million AVAX with tokens gradually released each quater. The current market cap of AVAX is around $100 million.

Results

Avalanche’s AVAX with its fixed capped supply, deflationary pressure, very strong utility, potential to receive air drops and low market cap, means it scores ✅✅✅. Polkadot’s DOT also has very strong utility with the need for auctions to acquire parachain slots, but has no deflationary mechanisms, no fixed capped supply and already valued at $3.8 billion, therefore scores ✅✅. Cosmos’s ATOM token is only for the Cosmos Hub, of which there will be many hubs in the ecosystem and has very little utility currently. (this may improve once IBC is released and if Cosmos hub actually becomes the hub that people want to connect to and not something like Binance instead. There is no fixed capped supply and currently valued at $1.1 Billion, so scores ✅.

All three are excellent projects and have similarities as well as many differences. Just to reiterate this article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important. For a more in-depth view I recommend reading the articles for each of the projects linked above and coming to your own conclusions, you may have different criteria which is important to you, and score them differently. There won’t be one platform to rule them all however, with some uses cases better suited to one platform over another, and it’s not a zero-sum game. Blockchain is going to completely revolutionize industries and the Internet itself. The more projects researching and delivering breakthrough technology the better, each learning from each other and pushing each other to reach that goal earlier. The current market is a tiny speck of what’s in store in terms of value and adoption and it’s going to be exciting to watch it unfold.

Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

If you are interested in accepting bitcoin as a payment method, there are several options available;

Can I mine bitcoin?

Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out.
If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. If you would prefer to keep it simple there are several good options. You can view the global node distribution here.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
bitcoin BTC 1 bitcoin one bitcoin is equal to 100 million satoshis
millibitcoin mBTC 1,000 per bitcoin used as default unit in recent Electrum wallet releases
bit bit 1,000,000 per bitcoin colloquial "slang" term for microbitcoin (μBTC)
satoshi sat 100,000,000 per bitcoin smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $10000 for one Bitcoin, a $10 meal would equal:
