Anza said the faster block times from the 200-millisecond upgrade on the Solana blockchain will shorten the validity window for transactions, which could complicate transactions requiring manual approval or offline signatures

Base blockchains that settle transactions on their own network, such as Ethereum, Solana, and Avalanche, competing on security, throughput, decentralization, and developer ecosystems.

Approaches to processing more transactions without sacrificing security or decentralization, spanning rollups, sharding, data compression, and faster consensus designs.
