On the evening of December 1, the Ethereum 2.0 beacon chain was officially launched, Up to now, 2.1 million Ethereum has been pledged, which marks the fourth phase of Ethereum is in progress.
Many small partners may not know how many stages the development of Ethereum is divided into, and what is the goal of each stage? Today, we will briefly introduce the development process and planning of Ethereum.
01Project
launch and test phase
At the end of 2013, Ethereum founder V God released the original white paper of Ethereum and launched the Ethereum project.
On July 24, 2014, Ethereum launched a 42-day crowdfunding campaign, which raised more than 30,000 Bitcoins and pre-sold 60 million Ether.
In May 2015, the Ethereum team released the last test network before the official version went live, codenamed Olympic.
02Mainnet launch
and upgrade
July 2015, Ethernet Square, the main Internet line , and escalating. According to the introduction in the white paper, the development of the Ethereum network is divided into four stages . The Ethereum team has given each stage a name full of literary and artistic atmosphere. They are Frontier, Homeland, Metropolis, and Serenity.
1, the front edge (Frontier)
frontier Square for the first phase of the Ethernet network, duration from July 2015 to March 2016. This stage is the initial stage of the Ethereum network . At this stage, there is only a command line interface and no graphical interface, which is mainly suitable for developers.
2. Homestead
On March 14, 2016, Ethereum entered the homestead stage. Compared with the frontier stage, the operation of the Ethereum network is more stable, and the security and reliability are improved. At this stage, the ease of use of Ethereum has been greatly improved , and ordinary users can also easily experience and use Ethereum. The Ethereum graphical interface wallet is produced at this stage.
3. Metropolis (Metropolis)
The third phase of the Ethereum network is Metropolis. The metropolis phase is divided into two small upgrades, namely Byzantium and Constantinople . Both of these upgrades are hard forks .
The Byzantine version will be upgraded on October 16, 2017. This upgrade mainly includes 5 Ethereum improvement proposals, realizing faster and safer transactions on Ethereum, making Ethereum smart contracts suitable for commercial transactions. At the same time, the difficulty of mining is increased, and the block reward is reduced from 5ETH to 3ETH.
The upgrade time for the Constantinople version is on March 1st of this year. This upgrade was originally estimated in the middle of 2018, and was later postponed many times for various reasons. It was originally expected that the consensus algorithm would be converted from PoW to a PoW/PoS hybrid consensus algorithm, but it was actually not realized.
Although the goals planned in the roadmap were not achieved, this upgrade also brought some changes to Ethereum. This upgrade includes 5 Ethereum improvement proposals. The main changes after the upgrade include: block rewards are further reduced, from 3ETH to 2ETH, the difficulty bomb is postponed for 12 months, and a shift is added to the Ethereum virtual machine. Instructions etc.
The upgrade of Constantinople is completed, marking the end of the Ethereum Metropolis phase.
4. Serenity
The fourth phase of Ethereum is the Serenity Phase. This is the last milestone in the Ethereum roadmap. The release time is to be determined. In the quiet stage, Ethereum will completely transition from PoW to PoS, and Ethereum will also enter the 2.0 stage.

summary
Counting from the release of the white paper at the end of 2013, Ethereum has gone through more than 6 years.
The development team is working hard for the last stage of the Ethereum roadmap. According to the plan, in the last stage, the consensus mechanism of Ethereum will be converted from PoW to PoS, and Ethereum will also enter the 2.0 stage.
Why do you think Ethereum should switch from a PoW consensus mechanism to a PoS consensus mechanism? Welcome to leave a message in the message area.
