As of the beginning of 2020, there are approximately 61 million Ethereum Classic (ETC) in circulation. This number will continue to decrease over time as more ETC are mined and taken out of circulation.

The total supply of ETC is capped at 210 million, so eventually there will only be a finite number of ETC in existence. The amount of ETC left unmined is called the “ether supply”.

The current circulating supply of Ethereum Classic (61 million) was mined over a period of about two years from its launch in July 2016 to June 2018. In that time, the mining reward was 5 ETC per block.

At the current mining reward of 3 ETC per block, it will take approximately another four years to mine all 210 million ETC.

The actual number of Ethereum Classic left unmined is slightly less than the theoretical maximum because a small percentage (less than 1%) has been lost or permanently locked up over time. For example, some early investors may have lost their private keys or accidentally sent their ETC to an incompatible address.

As a result, it’s estimated that there are around 209 million “unlocked” or “unspent” ETC, which will eventually enter circulation as they are mined.

In conclusion, there are around 61 million Ethereum Classic currently in circulation and 209 million still left to be mined. The total supply of Ethereum Classic is capped at 210 million, so eventually there will only be a finite number of ETC in existence.

As of July 2018, Ethereum has a market capitalization of over $41 billion, and its price has been as high as $1,422.53.

Each ETH token is worth $744.86.

There are currently 97,863,956 ETH in circulation, and the total supply is not expected to exceed 120,000,000 ETH.

Ethereum’s small decimal places (18) help to ensure that prices don’t fluctuate too wildly, and also help to make ETH more divisible and therefore more useful as a currency.

The vast majority of ETH transactions happen on exchanges, where prices are typically quoted to 8 decimal places. However, some Dapps (decentralized applications) allow users to trade in much smaller amounts, down to 1/100000000th of an ETH (0.

00000001 ETH).

So how many decimals is Ethereum? It depends on how you’re using it, but typically 8-18 decimal places.

Ethereum has had four major testnets: Morden, Ropsten, Rinkeby, and Görli.

Morden was the first Ethereum testnet and was launched in November 2015. It was quickly deprecated due to a bug that made it vulnerable to replay attacks.

Ropsten was launched in November 2016 and was the first Ethereum testnet to use Proof of Work (PoW). Ropsten was also eventually deprecated due to vulnerabilities.

Rinkeby was launched in April 2017 and is still active today. It uses PoA (Proof of Authority) which makes it more secure than PoW testnets.

Görli was launched in December 2018 and is the most recent Ethereum testnet. It uses PoA like Rinkeby but also has Parity’s “Aura” consensus algorithm for improved security.

So there have been a total of four major Ethereum testnets: Morden, Ropsten, Rinkeby, and Görli.

As of September 18, 2020, there were 10,363 Ethereum validators. This number has been steadily increasing since Ethereum launched in 2015.

The vast majority of these validators are running on the Ethereum mainnet, but there are also a significant number of validators running on Ethereum testnets and private networks.

Validators play a critical role in ensuring the security and stability of the Ethereum network. They do this by participating in consensus, which is the process of reaching agreement on the state of the network.

Consensus is reached through a process of voting, and validators that participate in consensus earn rewards for their participation.

The more validators there are on a network, the more secure and decentralized it is. This is because it becomes more difficult for any one entity to control a majority of the network and manipulate it for their own gain.

The increase in the number of Ethereum validators is a positive trend that indicates that the network is becoming more secure and decentralized over time. This is good news for all users of Ethereum, as it makes it more likely that the network will be able to withstand attacks and continue functioning smoothly.

As of September 2018, there are over 27,000 Ethereum nodes active around the world, with the vast majority of them (24,000) located in the US. The number of nodes is constantly increasing as more people begin to run them. Each node represents a single point of failure for the network and so the more nodes there are, the more resilient the network becomes. Nodes can be run by anyone and they don’t require any special hardware.

All you need is a computer with an Internet connection and enough storage to hold the Ethereum blockchain (which is currently around 25GB). running a node is a great way to support the Ethereum network and it can also be profitable as you can earn rewards for processing transactions.
