The 6th Anniversary of Ethereum looks back on the development history of Ethereum in the past six years

Ethereum was launched on July 30, 2015. On July 30, 2015, the first version of Ethereum was released. In the six years since its establishment, the network has withstood a nearly catastrophic early attack, experienced a controversial hard fork, and has a market value of more than $270 billion. ETH has become the second largest cryptocurrency by market value, second only to In Bitcoin.

2013-2014: the birth of ETH

Beginning in 2014, V God received a 100,000 yuan Teal scholarship from early Facebook investor Peter Teal to encourage dropouts to start a business, and began to develop the Ethereum project full-time. A legend kicked off, and the story of ETH began.

On October 5, POC6 was released. This is a significant version, and one of the highlights is the speed of the blockchain. The block time was reduced from 60 seconds to 12 seconds, and a new GHOST-based protocol was used.

2015: The Ethernet network was launched, and ETH was officially launched

In January 2015, the team released POC7.

In February 2015, the team released POC8.

In March 2015, the team issued a series of statements about the release of the Genesis block, and POC9 is also under intense development.

In May 2015, the team released the last test network (POC9), codenamed Olympic. In order to better test the network, during the Olympic phase, members who participate in the test network will receive Ether rewards from the team. There are many types of rewards, mainly including test mining rewards and bug submission rewards.

On July 30, 2015, the official Ethereum network was released, which also standardizes the official operation of the Ethereum blockchain.

From November 9th to 13th, 2015, Ethereum held a five-day developer conference (DEVCON 1) in London, which attracted more than 300 developers from all over the world.

2016: The split of the Ethereum community

On June 16, 2016, ETH was attacked by hackers, and approximately $60 million in ETH was stolen. On July 20, the Ethernet network was divided into two: Ethereum and Ethereum Classic.

2017: The rise of ICOs

The bull market in 2017 is about to start. In the last bull market, the most memorable thing is the prevalence of ICOs. Tens of millions of projects are funded by private equity through the use of Ether. Although the end of the bubble was all chicken feathers, ETH1.0 really stayed on the stage of 2017 history.

On March 1, 2017, the Enterprise Ethereum Alliance (EEA) announced its establishment, which claimed to be aimed at creating an enterprise-level blockchain solution and jointly developing industry standards.

On July 19, 2017, around 12:30 EST, a hacker made an unauthorized function call against a vulnerability in Parity Wallet 1.5 or later, launched an attack, and stole more than a total of more than three multi-signature contracts. One hundred and fifty thousand ethers caused a loss of about thirty million U.S. dollars based on the market value at the time.

On November 6, 2017, due to a code vulnerability accidentally triggered by developers and users “misoperation”, the Parity multi-signature wallet created after July 20 was completely paralyzed, resulting in a total value of more than $154 million and a total of 93 Ten thousand ether coins have been frozen and locked, and have not been recovered yet.

2018: the arrival of the bear market

In 2018, ETH is facing an upgrade in Constantinople. However, the upgrade has been delayed repeatedly, and the price of ether has plummeted due to the impact of the bear market environment.

On December 10, 2018, Vitalik announced on Twitter that in the future, blockchains using Proof-of-Stake (PoS)-based sharding technology “will be thousands of times more efficient.”

2019: The eighth upgrade of the Ethernet network

For Ether, 2019 is a year to lay a solid foundation. This year, Ether achieved the eighth upgrade of Constantinople. One of the main goals is to ensure that the Ethereum blockchain is compatible with the anonymous Zcash (ZEC) cryptocurrency, and to improve the network’s performance through the SNARK and STARK zero-knowledge proof protocols. Scalability.

Ethereum 2.0 deployment deposit contract in 2020

On November 4, the Ethereum Foundation stated on its official blog that it had released the Ethereum 2.0 specification v1.0, including the Ethereum 2.0 mainnet deposit contract address 0x00000000219ab540356cbb839cbe05303d7705fa. Ethereum 2.0 Phase 0 will be created at Unix timestamp 1606824000, UTC time is December 1, 2020.

With the rise of DeFi in 2020, people’s eyes are once again focused on ETH.

London upgrade in 2021

On July 15th, the Ethereum Foundation issued a formal announcement of the London upgrade. After announcing the successful deployment of the testnet, the London s upgrade is fully ready to be activated on the Ethereum mainnet. It will be launched at block 1,2965,000, and is expected to be on August 5. Among them, the London upgrade includes 5 EIPs, EIP-1559, EIP-3198, EIP-3529, EIP-3541 and EIP-3554. Each EIP contains code changes aimed at optimizing and improving Ethereum.

Ethereum reached a new high on May 12, with a single currency price of 4371$.
