Solana Raises Transaction Size Cap to 4,096 Bytes for ZK Proofs

The headline number understates the change: quadrupling transaction size is really about letting cryptography that was previously awkward on Solana — ZK proofs and large multisigs — execute natively rather than being fragmented across calls. That matters most for teams building privacy or verification-heavy applications who had been working around the ceiling, and for the network's pitch as a venue for heavier computation. Whether the new format sees real adoption, and how it interacts with existing tooling, is the open question worth watching.
