Crypto technology — cryptography, scaling, and protocol research

Technology coverage on CoinArticle goes deep on the cryptography, scaling research, and protocol engineering shaping the next generation of crypto infrastructure. We follow zero-knowledge proofs (SNARKs, STARKs, Plonky2, Halo2), modular versus monolithic chain debates, MEV and proposer-builder separation, account abstraction (ERC-4337 and 7702), data-availability sampling, danksharding, post-quantum cryptography research, and the protocol-level upgrades — Ethereum hard forks, Bitcoin soft-fork proposals, Solana firedancer rollouts — that change how value moves on-chain.
