Hybrid rollups: The silver bullet for scalability and security on Ethereum

Image
Can the Ethereum blockchain be both scalable and secure? This project says “Yes,” through a novel concept called hybrid rollups. Graphic designers have an old saying: “Your project can be fast, cheap or good — pick two.” It’s a classic trilemma. Rushing to create something might mean it’ll be delivered quickly, and therefore less expensive. Then again, the end product could be disappointing. If customers go the “cheap and good” route instead, they’re willing to wait a while — it’s going to take time, and projects that pay better will be prioritized. For years, there’s also been a lot of talk in the blockchain world about a trilemma in terms of decentralization, security and scalability: decentralized networks can only provide two of the three benefits at any given time. Experts argue that scalability requires a trade-off with security . In this case, a network can handle more transactions, but the risk of an exploit increases. But this doesn’t necessarily have to be the case. Right n...

Zero-knowledge proofs coming to Bitcoin, overhauling network state validation

Zero-knowledge proofs have powered the development of Ethereum layer 2s — and now they’re coming to Bitcoin. Bitcoin (BTC) users will soon be able to make use of zero-knowledge proofs (ZKPs) to expedite the process of verifying individual blocks and, eventually, the entire blockchain.  Swiss-based nonprofit ZeroSync Association is developing tooling which allows users to validate the state of the Bitcoin network without having to download the blockchain or trust a third party for verification. ZeroSync Association is an organization that was formed to develop and maintain open-source software that enables succinct zero-knowledge proofs (ZKPs) on the Bitcoin blockchain. The group makes use of StarkWare’s proprietary zero-knowledge Scalable Transparent Argument of Knowledge (zk-STARK) validity proofs to generate ZKPs for the Bitcoin network. The tool promises to overhaul the process of verifying the Bitcoin blockchain, which still requires node operators to download a large amount of d...
