Ethereum successfully launches dress-rehearsal testnet! Ethereum successfully launched dress-rehearsal testnet for Ethereum 2.0 Phase 0, dubbed Zinken.
The launch occurred on Monday at 12 PM UTC And was relatively smooth with enough participation and did not experience major bugs.
The testnet was organized following the launch of Spadina, the first rehearsal that aimed to test the launchpad for stalkers.
Spadina suffered from low participation rates, however. Many believed that participation was low due to the lack of economic incentives, however, further research pointed towards bugs in clients as the fault for the bulk of Spadina’s problems.
A high participation rate is critical for maintaining the integrity of the network – more than 66% of the stake must confirm blocks in order for the blockchain to be considered reconciled and finalized – blocks at that point can no longer be reversed.
Zinken became the first testnet that passed the finalization threshold within a few minutes of going live. This places Zinken as one of the most successful testnet launches thus far. Participation was below the ideal number of 90%, but was still above 75% since the beginning of the launch.
This could also be the sign that developers were looking for before proceeding with the main net launch. Vitalik Buterin was present during the call, adding that the team may still do a few more rehearsals, but that they’d probably be reserved to developers.
Ethereum 2.0 Phase 0 will feature a Beacon Chain – the first building blocks of the new blockchain. Activity on Ethereum 1.0 will continue as before, however. The two blockchains will have nearly no interaction with one another beyond a one-way deposit contract. Until later stages kick in, stalkers will be unable to withdraw or transfer the ETH they’ve committed.
