Сообщение ChainCatcher, Джастин Дрейк на платформе X заявил, что Ethereum L1 больше не будет использовать хэш-функцию Poseidon, дружественную к SNARK, которая доминировала с 2019 года, и перейдет на традиционные хэш-функции, такие как SHA2 или BLAKE2s.Это изменение основано на прогрессе в области проектирования SNARK, сосредоточив внимание с "дружественного к SNARK хэша" на "дружественный к хэшу SNARK". Благодаря нативному выравниванию булевых операций в традиционных хэшах в двоичном поле, производительность доказательства традиционного хэша в SNARK достигла 1 миллиона в секунду, с накладными расходами около 100 раз.Исследования, такие как Binius и Flock, способствовали соответствующему прогрессу. Команда Ethereum Foundation по постквантовым технологиям продвигает этот маршрут, дорожная карта включает развертывание производственного уровня leanVM в 2027 году, а также развертывание на уровне консенсуса, уровне исполнения и уровне обработки данных в 2028 году.Джастин Дрейк также отметил, что возможности ИИ в области криптоанализа усилились, что привело к недавним ударам по схемам HAWK и SQIsign. Основные хэш-схемы используются для постквантовых подписей в блокчейне. Тенденция к автоматизированным исследованиям с открытым исходным кодом также ускоряется, SNARK.fast достиг доказательства BLAKE3 на уровне 1,8 миллиона в секунду.

ChainCatcher news, the decentralized AI full-stack data layer Poseidon has released a lightweight white paper, announcing its commitment to building a full-stack supply and demand infrastructure for AI training data.Through subnets and modular data pipelines, global data providers can securely offer copyright-compliant AI training data via Poseidon. All data will be registered on the Story chain as programmable IP assets, achieving copyright traceability, while accompanying incentive mechanisms allow data contributors to earn rewards. Poseidon aims to address the scarcity of AI data and the long-tail problem, promoting open and sustainable AI development. Previously, the project launched the Poseidon App and within two weeks garnered over 30,000 hours of audio data contributed by users worldwide, while completing a $15 million seed round financing led by a16z crypto.

ChainCatcher news, according to dynamic data from RootData X, in the past 24 hours:The Ethereum yield and infrastructure company The Ether Machine (Nasdaq: ETHM) has attracted attention from Chris Dixon, Joseph Lubin, Anthony Sassal, and others.The full-stack decentralized data layer Poseidon has garnered interest from a16z partners Chris Dixon and Ali Yahya, as well as Story Protocol founder and CEO SY Lee.The decentralized stablecoin protocol Mento has caught the attention of Tomasz Stanczak, co-executive director of the Ethereum Foundation.The progressive mortgage system Divine has attracted interest from former a16z Crypto partner Jane Lippencott.

ChainCatcher news, according to The Block, the decentralized data layer Poseidon has completed a $15 million funding round, led by a16z.It is reported that Poseidon is built on the Story Protocol and aims to unlock high-quality training data for the "next generation of entity AI." Poseidon is incubated by the Story team and is dedicated to solving the challenges of acquiring high-quality, usable, and legally authorized training data in the AI field.Chris Dixon, founder of a16z Crypto, stated that Poseidon's decentralized data layer will establish a new economic foundation for the internet, incentivizing creators and suppliers to provide diverse data inputs for the next generation of intelligent systems. The project will offer AI developers access to IP-secure and legally compliant training data through the programmable intellectual property layer and immutable registry of the Story protocol.

ChainCatcher message, Ethereum co-founder Vitalik Buterin stated, "I strongly encourage researchers to participate in the Poseidon cryptanalysis program. We are seriously considering migrating Ethereum to the Poseidon hash to optimize zk-prover friendliness, so having more information about its security properties is of great value."The application deadline for the Poseidon funding program has been extended to March 15, 2025.

ChainCatcher news, Web3 AI company Eidon has completed a $3.5 million seed round financing, led by Framework Ventures, with participation from the Cayman Islands venture capital firm cyber.Fund. The company plans to use the seed funding to develop its team.Eidon encourages users to provide data for training AI models. Users can submit new data, such as fine hand movements or object interactions, while others can verify the authenticity of the data through an upcoming blockchain audit. Eidon’s first network version will go live on November 12. This network includes a platform application for data evaluation and collection, as well as an open sequencer for record preservation.

ChainCatcher news, according to the official Twitter, Ola has recently supported Poseidon2 hash in its proof system. Compared to the original Poseidon hash, it has achieved a 40%+ performance improvement for provers.It is reported that Poseidon2 is a new hash algorithm that maintains the same level of security as Poseidon hash while having better zk-friendly characteristics. Since zk-friendly hash algorithms are widely used in Ola's proof system, including private state tree, public state tree, verification process, plonky2 recursive process, etc., after in-depth research on the algorithm and implementation of Poseidon2 hash in the Horizen Labs paper, Ola has officially integrated it into the proof system.According to official sources, the Ola ZKVM testnet will be launched in early Q4 of this year, and more development details will be announced soon.

Chain Catcher news, Edward Snowden will attend the ZK House event hosted by the Manta Network development team p0xeidon labs in Bogotá, Colombia, from October 10 to 11. The lineup of speakers also includes key members from the Ethereum Foundation, 0xParc, Veridise, NYM, Aztec, Polygon, and Electric Coin Company (ZCash).It is reported that the topics will focus on the latest research directions in ZK (Zero-Knowledge) technology, including L2 security, ZK smart contracts, ZK cross-chain information transmission, and discussions on cryptography itself in the context of ZK. Other co-hosts of the event include Scroll and Veridise, with sponsorship and support from Polychain Capital, NYM, and Status. (Source link)

Chain Catcher news, the Web3 privacy protection protocol Manta Network has launched a new introduction website for its development team p0xeidon labs at p0xeidon.xyz, and announced the establishment of the research project Poseidon VM.As the first EVM-compatible zkApp-friendly virtual machine, Poseidon VM enables zkApps to have privacy, scalability, and provability, while users will also benefit from efficient zkApp transactions, which can be 2000 times cheaper compared to other Layer2 solutions.Unlike the simpler designs of Aleo and Mina, Poseidon VM provides zkApp developers with layered programming abstractions, including the EVM tools that DApp developers are most familiar with and love. Poseidon VM offers a rich set of system-level zk-Precompiles and also allows DApp developers to directly use Solidity to code zkApps.It is reported that p0xeidon labs is a team composed of top developers from around the world, dedicated to building Web3 privacy, believing that privacy is a fundamental right, and striving to create and deploy tools to accelerate the global adoption of privacy through zero-knowledge proofs.The projects the team is building include the plug-and-play privacy layer parachain Manta Network in the Polkadot network, and the canary network Calamari Network on Kusama. Additionally, the team stated that Manta will announce a trusted setup ceremony in the coming days, which is also key to the privacy payment protocol MantaPay implemented through zero-knowledge proofs.
