On May 4, 2020, the height of the Ethereum block reached 10 million. In the past five years, the total computing power of calculating 10 million blocks is 15 zettahashes (ie 15 * 10 ^ 21). However, some modern graphics cards such as GTX 1080 Ti take more than 150 million years to complete this work.
In our journey towards this milestone, there have been many known forks. Although the fork refers to the separation of the new chain from the main chain, the old chain is usually abandoned, so people also associate the fork with the “network upgrade”.
Now, let’s review the fork that Ethereum has experienced so far, and see how the current Ethereum mainnet has developed.
On May 9, 2015, the Ethereum Foundation released the Olympic: Frontier pre-release.
As a proof of concept, the Olympics ’release will provide a reward of 25,000 ETH in total for rewards to users who send the most transactions, miners who process the most transactions, or to encourage miners to discover major issues, such as in Go and C ++ A (substantial) fork is initiated between the clients.
This version lasted 14 days. Technically, the Olympics is completely different from the Ethereum mainnet, so it should not be included in the hard fork list. Nevertheless, the frontier version of the genesis block still comes from this stage of the Olympics.
The release of Frontier represents the first official announcement of Ethereum “Eth 1.0”. This release is the creation of the genesis block, which contains 8893 transactions that users bought ETH during the official pre-sale.
A total of 72 million ETH is pre-mined, of which nearly 12 million ETH is owned by the Ethereum Development Fund.
