Introducing the BAM Early Adopter Subsidy Program
Read JIP-31 on the Jito Network forum (here).
Jito’s Block Assembly Marketplace (BAM) is one of the more meaningful upgrades Solana can make to its execution layer. The core idea is that Solana’s long-term goal – supporting Internet Capital Markets at scale – depends not just on raw throughput, but on the quality of execution: predictable timing, low jitter, uniform scheduling, and reducing incentives for harmful MEV.
The latest JIP from the Jito DAO starts from a practical constraint: BAM only delivers those network-level improvements if a meaningful portion of stake is actually running the BAM client. In other words, adoption is the prerequisite. So the proposal introduces a temporary BAM Early Adopter Subsidy Programme designed to make that early rollout economically attractive for validators.
The mechanism is straightforward: For a limited period, the DAO would redirect protocol fee revenue into a subsidy pool and distribute that value to validators who run BAM and follow the execution contract described in the BAM documentation – namely, executing transactions in the correct order and providing correct execution feedback and state information. Because these behaviors are the default in the BAM validator client, the programme is intended to be operationally simple: run the client, stay compliant, and you’re eligible.
Eligibility is also meant to be broad. It is not limited to validators in the Jito Stake Pool; the subsidy is positioned as a network-wide adoption push. The draft includes a minimum stake threshold (50k SOL) and a short “warm-up” period. Validators need to run BAM for several epochs before becoming eligible, and they lose eligibility if they stop running BAM or violate the contract.
On distribution, the proposal aims to keep incentives strong across the validator set while ensuring largest validators completely dominate the subsidy distribution. It does that by using a simple “effective stake” curve: up to a certain stake level, payouts scale normally with stake, then the marginal subsidy rate tapers, and eventually flattens beyond a cap. The intent is to encourage early participation across a wider validator set while preserving cost efficiency. Unclaimed rewards would roll forward into future epochs, increasing what active participants can claim.
The programme is designed to be temporary and time-boxed, beginning at full allocation and then tapering down to zero by the end of Q2 2026.
The promised upside is that accelerating BAM adoption accelerates the conditions that make Solana attractive for high-performance markets: more deterministic execution, less jitter, more consistent scheduling, and a healthier environment for liquidity and applications.
In short, this JIP is a “growth mode” proposal. It temporarily re-routes protocol revenue to incentivize validators to adopt BAM earlier, with the expectation that faster adoption compounds into better execution quality for the whole network—and that once the network reaches the desired adoption threshold, the DAO can shift back toward longer-term value accrual strategies.
