Solana has no single document that sets out its protocol rules. They are spread across years of improvement proposals (SIMDs) and the code of its validator clients.
@anza_xyz's Brennan Watt (@bw_solana) has proposed one living Solana protocol spec instead: each change becomes a pull request against it, merged only when the change goes live on Mainnet.
He has already posted an 18-chapter draft. It is a proposal for feedback; nothing has been adopted.

Solana V1 transactions are locally testable now — mainnet activation expected in a couple of weeks.
Max transaction size: 1,232 bytes → 4,096 bytes (3.3×).
Two breaking changes land the moment the first V1 tx hits mainnet:
— RPC callers: add maxSupportedTransactionVersion: 1 to getTransaction/getBlock, or you get error -32015 on any block containing a V1 tx
— Indexers: ComputeBudget scanning returns zero for V1; limits moved to transactionConfig
Priority fees also change units: V0 uses micro-lamports per CU; V1 uses total lamports.
SDK minimums: solana/kit 8.0.0, solana-* crates 4.2.x, solders 0.29.0.
What are you planning to build with the extra headroom?
