Add tx root of successful txs to each block so that inclusion can be verified just by processing headers (see Bitcoin SPV).

Alternatively, nodes could produce signatures over accepted txs periodically (may require extra latency) so anyone can verify inclusion with just p-chain syncing.

Could accomplish this by exporting a "proof" warp message so people that don't need this don't need to pay more.

To avoid interference with warp (where we want to prove + warp), we could add a Boolean to txs that makes it "prove-able" and saves txID to state.

Could do this with all tx roots to allow any tx/state root content to be proven.

May also want to make exported warp messages per block a root too (so any network can verify arbitrary amounts of data with a single multi-signature).
