3 High-Potential Altcoins to Buy as US-China Tariff Tension Eases – Find Out Experts’ Top Picks

PANews reported on October 21st that, according to CoinDesk , Coin Metrics co-founder Nic Carter called quantum computing the greatest long-term risk to Bitcoin's core cryptography. He explained the one-way nature of deducing public keys from private keys via the secp256k1 elliptic curve, and pointed out that exposing public keys on-chain during spending transactions increases the potential attack surface. Carter recommends avoiding address reuse in the near term to reduce public key exposure, and promoting post-quantum signature schemes and feasible migration paths in the long term. A subsequent article in his series will discuss the " post-quantum break " scenario.

PANews reported on October 21st that DoodiPals, a mini-entertainment project within the Solana ecosystem centered around the "DOODI" IP, announced it will be relaunched after completing a security review. Users who held DOODI before the hack will receive a 1:1 reissue. The project organizers urged users to suspend purchases of DOODI pending further announcements, stating that the situation is under control and will return to normal after the relaunch. Previously, security researcher Cos said that due to the leakage of private keys, $DOODi in dozens of addresses was stolen and converted into SOL, and the hacker made a profit of about 917 SOL.

The post Ethereum Founder Vitalik Buterin Explains GKR, Unbelievably Powerful Tech Scheme appeared on BitcoinEthereumNews.com. Ethereum’s Vitalik Buterin explains GKR, cost-effective and fast family of prover protocols Combined with ZK-SNARK, ZK-STARK, scheme brings privacy Named after their inventors, Goldwasser, Kalai and Rothblum, GKR proofs — as explained by Ethereum founder Vitalik Buterin — makes all mainstream cryptography practices fast and resource-efficient. Ethereum’s Vitalik Buterin explains GKR, cost-effective and fast family of prover protocols In his guide yesterday, Vitalik Buterin, founder of Ethereum (ETH) blockchain, explains what is under the hood of modern ZK proving approaches. Goldwasser-Kalai-Rothblum proofs, or GKR proofs, is the backbone element behind their speed and performance. First described in 2015, the scheme achieves supremacy thanks to its optimized development. While working on data proving, GKR allows only make commitments to inputs and outputs, ignoring intermediary layers. In this case, Buterin describes commitments as putting the data into a cryptographic data structure, either a KZG or a Merkle tree, that allows customers to prove queries about specific things regarding that data. This development paved the way toward zkEVM and zkML blockchain architectures that benefit from ZK cryptography, generating proofs of operations on L2 and verifying them on Ethereum (ETH). Combined with ZK-SNARK, ZK-STARK, scheme brings privacy This scheme is also used in large language models and other AI concepts. Combined with other ZK technologies, it is what protects privacy in L1/L2 interactions: GKR is not “zero knowledge”: it only handles succinctness, not privacy. If you want zero knowledge, wrap the GKR proof in a ZK-SNARK or ZK-STARK. As covered by U.Today previously, recently, Buterin showcased in his X Kohaku, a fork of Ambire, another security development in the Ethereum (ETH) ecosystem.
