"Although we found several major issues during the verification of the deposit contract form, some of them were caused by hidden Vyper compiler bugs, but in the latest version (v0.10.0), all deposit contract issues Have been properly repaired. "
According to the company's announcement, the deposit contract is a "channel" to participate in Ethereum 2.0. Validators on the new PoS beacon chain need to send transactions to the deposit contract via the Ethereum 1.0 network to deposit ETH.
The deposit contract will record the transaction history and lock these funds on the Ethereum 1.0 chain for future redemption on the beacon chain. This type of smart contract uses a Merkle tree data structure, which can effectively store deposit history.
Ethereum 2.0 coordinator Danny Ryan confirmed that this formal verification is the last obstacle to (Ethereum 2.0), he added:
"This is the main review and verification. This contract and formal verification process is now undergoing public review."
There are currently no other audit plans for this deposit contract, but two audits on the beacon chain are expected in February.
It was reported last week that 22,000 active validators were running the first Ethereum 2.0 client on the test.
These client testnets may begin to connect with each other before the genesis block testnet, which heralds the implementation of the first PoS deployment.
Earlier this year, nine independent teams began to deploy the beacon chain of Phase 0, which is expected to be released in the second quarter of this year.
