Protocols: Solana
What is Solana?
Solana matters because it asks a different question from many blockchains: what if the base layer itself were fast enough for markets, payments, and consumer apps? Its design tries to push more ordering, execution, and networking work into the protocol so transactions can clear quickly and cheaply on a single shared chain.

What is Proof of History?
Proof of History is Solana’s attempt to solve a specific blockchain problem: agreeing on the order of events without making the whole network constantly negotiate what time it is. It does that with a sequential hash process that acts like a cryptographic clock, then hands that ordering to consensus.

What is Sealevel?
Sealevel is the idea that makes Solana’s high throughput plausible: transactions must say in advance which accounts they will read and write, so the runtime can safely run non-conflicting work at the same time. That sounds simple, but it changes how smart contracts are structured, scheduled, and optimized all the way down to the hardware.
