Vitalik Buterin, co-founder of Ethereum, proposes a deeper examine of the Poseidon hash operate to discover methods networks can enhance the proof effectivity of zero data (ZK).

In a February twenty sixth submit on X, Buterin inspired cryptostatists to hitch Poseidon’s safety analytics program, citing a message that prolonged the deadline for the funding software to March fifteenth.

He mentioned:

“We’re severely contemplating Ethereum to transition to Poseidon Hash to optimize ZK Prover’s familiarity, so having extra details about its safety properties could be very excessive worth. there’s.”

What’s Poseidon?

Poseidon is a cryptographic hash operate particularly designed for zero-knowledge functions.

Not like conventional hash capabilities akin to SHA-256, Poseidon is optimized for Zero-Information (ZK) Proofs. That is an encryption approach that means that you can confirm transactions with out revealing confidential particulars.

ZK Proofs have gotten more and more essential in Ethereum scaling efforts, particularly in rollups that deal with transactions off-chain earlier than finalizing them on the primary blockchain. Poseidon’s effectivity reduces computational prices and makes these options sooner and extra accessible.

In accordance with Poseidon Cryptanalysis:

“The Poseidon Hash operate is utilized in many Ethereum functions that deal with verifiable calculations. It is likely one of the most up-to-date Stark Benchmarks performers by StarkNet, and is a variety of protocols utilizing ZK proofs. It’s a promising candidate to be used with the Ethereum L1.”

Neighborhood Response

A few of the Crypto Area verify that Poseidon’s potential adoption is being adopted as a optimistic step in Ethereum’s effectivity, whereas others have raised considerations.

Ye Zhang, co-founder of Ethereum Layer 2 Challenge Scroll, questioned whether or not Poseidon’s advantages outweigh the trade-offs.

Chan identified that varied compositions of Poseidon may restrict Snark’s alternative and scale back flexibility. He additionally identified that Poseidon is considerably slower than alternate options like Blake and Keccak.

Zhang added that Scroll first used Poseidon, however efficiency concerns will return to Merkle Patricia Tree (MPT) with Keccak with future upgrades.
