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.
NOTE: WARNING: It is important to remember that the number of testnets in Ethereum can change over time, and there is no guarantee that a particular testnet will remain in existence. It is also important to note that some testnets may be more reliable than others. Therefore, it is important to do your own research and make sure to use only trusted testnets.
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.
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.
Yes, Ethereum has a testnet. The Ethereum testnet is called Ropsten. Ropsten is a proof-of-work testnet that mimics the Ethereum mainnet.
As of September 2018, about 60 million ETH had been premined. Prior to the launch of Ethereum, a total of 72 million ETH was created, which included the 60 million ETH premine and 12 million ETH that was mined during the genesis block. Of the 60 million ETH that was premined, 20% was sold to investors in a private sale, while the remaining 80% was retained by the Ethereum Foundation.
Ethereum addresses are generated randomly and are composed of the following characters:
1. Lowercase letters a-z
2. Uppercase letters A-Z
3.
Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third party interference. Ethereum is a public blockchain-based platform that uses the cryptocurrency ether to fuel its transactions. Ether is mined by computers around the world and then traded on decentralized exchanges.
Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third party interference. Ethereum is a programmable blockchain. It means that developers can build applications on Ethereum.
Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third party interference. Ether is the native cryptocurrency of the Ethereum platform. It is used to pay for gas, a unit of computation used in transactions and other state transitions.
As of July 2018, there are a total of 102,112,496 ETH in circulation. This number is ever-changing and does not include any unclaimed ETH that may be lurking in wallets or smart contracts. To put this into perspective, let’s compare it to the world’s supply of gold.
Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third party interference. Ethereum is unique in that it allows developers to create their own decentralized applications, called dapps, on its blockchain. This means that anyone can build a dapp on Ethereum, as long as they have the technical know-how.
