How Solana differs from other chains
Solana separates code from data. A program is stateless, and all state lives in accounts that every instruction must declare up front. That shapes the design from day one.
We plan for account validation, program derived addresses, compute limits per transaction and transaction size limits. Many bugs on this chain come from a missing account check, so those checks are written and tested first rather than added at the end.
We also agree with you early who holds the upgrade authority, since that decides who can change the program after launch.
