MPP enables sequence number coalesced transactions for high TPS write operations. Transactions accepted by the MPP plugin are limit to pure-writes to the enrolled program. CPI is disallowed. A high floor microlamport per CU requirement is in-place to incentivize efficient updates to market state.
See ./maker/README.md for more information.
The BAM preconf firehose contains pre-confirmed but committed to state transactions processed by BAM leaders. Validators can opt-out of having their preconfirmed transactions included in this stream.
