Jito: More Than 50 Percent of Solana Validators Run BAM
Jito reports that over 50 percent of Solana validators run the Block Assembly Marketplace (BAM). The public roadmap had previously cited 30 percent of stake as the 2026 target.
What Jito Reported
Jito announced via its official X account that more than 50 percent of Solana validators run the Block Assembly Marketplace (BAM). The figure comes from Jito’s own communications and has not been confirmed by us against a second primary source; it is labeled here as a self-reported claim (developing).
Also note the difference between two metrics that are easily conflated: share of validators by count and share of total stake are not the same thing.
Context
Confirmed context on the BAM rollout:
- BAM went live on Solana mainnet on September 25, 2025.
- The public roadmap cited a milestone of 30 percent or more of total stake over the course of 2026, with full coverage as the longer-term goal.
- A majority of validators would therefore be a notable step beyond the publicly stated milestone so far — which makes a second confirmation all the more relevant.
What BAM Is
BAM is Jito’s block-construction layer for Solana, aiming at verifiability, privacy, and programmability: transactions are processed in trusted execution environments and stay encrypted until execution, while the ordering is made cryptographically verifiable. We explained the details here: Jito FireBAM on Frankendancer.
What to Watch
- Whether Jito backs the 50 percent figure with a verifiable data breakdown (count versus stake)
- How the distribution splits across Agave, Frankendancer, and Firedancer clients
- What broad BAM coverage means for front-running protection and block determinism on the network
