Poseidon | Crypto

Advances in compact proofs have erased Poseidon’s previous performance advantage, according to researcher Justin Drake. The Ethereum Foundation is moving away from the Poseidon hash function in its planned post-quantum architecture, according to researcher Justin Drake.  On Thursday, Drake said the foundation was abandoning Poseidon and turning to established alternatives such as SHA or BLAKE. A hash function converts data into a fixed digital fingerprint, enabling computers to check that information has not been altered.  Poseidon had been considered for future post-quantum systems such as leanVM, which would help Ethereum efficiently verify large volumes of blockchain activity. Those systems have not yet been deployed on mainnet.  Read more

Poseidon secures $15 million led by a16z Crypto to build a decentralized, IP-cleared data pipeline for AI training. Poseidon has secured $15 million in seed funding led by a16z Crypto to build a decentralized data layer designed for artificial intelligence training. The San Francisco-based full-stack AI data layer said it aims to tackle the scarcity of high-quality, IP-cleared training data in AI development, according to a Tuesday announcement shared with Cointelegraph. “LLMs and compute are no longer the bottlenecks; it’s high-quality data that’s missing,” said Sandeep Chinchali, Poseidon’s chief scientist and also chief AI officer at its incubator, Story Protocol.
