This pilot project used encryption proofs to validate each transaction and Block without the need to rerun the entire Blockchain. This indicates that even large networks like World Chain, based on the OP Stack, can eventually become ZK rollups. "World Chain challenged us to prove that ZK can operate at their scale," said Uma Roy, co-founder of Succinct, in a statement.

The system will be developed based on EigenLayer's infrastructure, using its stake mechanism and EIGEN Token to verify the truth through "intersubjective", which relies on community consensus rather than purely objective data. EigenLayer's technology allows users to reuse already staked ETH or liquidity stakeToken to secure additional services such as Oracle Machine, while benefiting from the security of the Ethereum network.

LayerZero CEO pointed out on social media that there are critical issues with the Across Protocol Token contract, which mistakenly exposes a functionality that should have been an internal private function, allowing the contract owner to withdraw Tokens from any wallet and arbitrarily zero out the account balance. Additionally, both the Across Protocol and UMA Protocol contracts have the ability to mint an unlimited number of Tokens. The solution is to transfer the contract ownership to a new Smart Contract to prevent excessive issuance and ensure that the new contract does not include the functionality to transfer ownership. The new contract must be immutable.
