Justin Drake, a researcher at the Ethereum Foundation, has published a paper revealing the details of the BeamSNARKs algorithm, an enhanced ZK algorithm that allows certifiers to prove the authenticity of claims to validators without revealing the underlying data or requiring interaction. For Ethereum, the BeamSNARKs developed and implemented by Moonchain are transformative in two key aspects: privacy and scalability. In terms of privacy, BeamSNARKs allow transactions or computations to be verified without exposing sensitive data, thus enabling use cases such as confidential transactions and private smart contracts. It is reported that Beam Chain is an indispensable consensus layer improvement in the Ethereum 3.0 era. This is a proposal to redesign Ethereum announced by Justin Drake at DevCon. Ethereum is expected to take several years to completely transition from the PoS era to the ZK era, when Ethereum itself will be fully capable of ZK.
