On February 28th, etheric real estate developers agreed to upgrade the Sepolia test network (Testnet) according to the overall target time for promotion in Shanghai, which is also an important measure to be taken by the blockchain to allow the withdrawal of ETH.

Sepolia is a closed test network used only by etheric developers and is the second of its kind to promote. Earlier this week, Zhejiang Test Network itself did a good job of simulating the withdrawal of ETH bets. Another test network will be upgraded, and the main etheric block chain is expected to experience Beijing's hard bifurcations next month.

The Sepolia test network is closed to developers who run validators on the Internet. By comparison, Zhejiang Province is a public release test network, which means it is open to everyone, including bets on service providers who want to practice bets on the release of ETH.

After Sepolia relies on its own round of tests, Gorli will become the final test network for Shanghai to promote. Golly will be a much-anticipated test because it is the largest published Ethernet test network and represents the last chance for chip service providers to guarantee the efficiency of ETH withdrawals before they are released in downtown Shanghai.

Lotte door and window Busa, a DevOps technical engineer at the Ethernet Foundation, told WJB that the difference between the three tests boils down to "the number of visitors and network load".

There is no doubt that Shanghai is the first hard bifurcation of the ether since it was put together last September. In September last year, the ether chose to abandon the old and highly polluting work unit certification (PoW), and then chose the risk confirmation (POS) consensus mechanism. Under POS, ETH is "betted" on the blockchain as a system to assist in authentication and protect buying and selling.
