@CoinList is still holding my @doublezero tokens for 2 weeks. I passed the KYC, joined the sale, and got my allocation — but now they forced a Re-KYC and froze my account for days. I can’t access my funds. This is unacceptable. #CoinList #DoubleZero

BBM – The Next Stage in Block Production on Solana
From BAM to BBM: Evolution of the Approach

During the development of the Block Assembly Marketplace (BAM), the Shiroi team concluded that the initial concept had significant limitations and required substantial modifications to achieve maximum efficiency. Architectural analysis and practical testing demonstrated the need for a deeper rethinking of the block production model in Solana.

The result of this work is the Block Builder Module (BBM) — an evolution of BAM with fundamental improvements and new capabilities.

What is BBM?
BBM (Block Builder Module) is the evolution of BAM, aimed at building a more efficient and fair system of block production in Solana.

How does it work?

Current Solana model:
- Validators independently produce blocks;
- They sort and order transactions;
- Full control over block assembly.

Proposed BBM model (PBS-like):
- Validators do not assemble blocks themselves;
- Validators only add assembled blocks to the network;
- Block production is delegated to BBM.

Key Advantages.

1. Transparency & Fairness:
- Block production becomes fully observable and auditable;
- Fairer competition among participants.

2. Efficient MEV Utilization:
- Local auctions instead of centralized structures;
- Custom scheduler for optimal transaction ordering;
- Fairer competition for sniping, arbitrage, liquidations, and other trading opportunities;
- More participants get a chance to bid;
- Only those paying the highest price succeed.

3. Spam Reduction:
- No incentive for transaction spamming: arbitrageurs and snipers lose the need to flood the network with transactions just to outpace each other;
- Winners are determined by bid price, not speed or volume;
- Reduced network load from redundant transactions.

4. Increased Throughput:
- More transactions processed per slot;
- Optimized block time usage.

Problems Addressed by BBM.

Current challenges in Solana:
- Time manipulation: According to @ChorusOne, timestamp games increase block rewards but harm the network;
- Client inequality: Firedancer (@jump_firedancer) captures significantly higher rewards compared to standard Agave (@anza_xyz);
- Execution inefficiencies: Issues with execution and scheduling.

BBM solutions:
- Eliminates advantages from time manipulation;
- Levels the playing field across all client types;
- Optimizes execution and scheduling processes;

Economic Benefits
Data from @0xGhostLogs: arbitrageurs on average pay 30–50% of their profits as tips, showing massive potential for validator revenue growth.

Expected outcomes:

1. Higher validator revenues through:
- Increased competition;
- Greater process transparency;
- Fairer distribution of all MEV opportunities.

2. Fairer competition among traders: more time to submit bids in auctions instead of relying on “perfect infrastructure” (low latency, validator proximity)

Technical Details

Architecture:
- Clear role separation: block production vs. block addition;
- Local auctions for all MEV opportunities (arbitrage, sniping, liquidations, etc.);
- Custom scheduler for optimal transaction ordering.

Integration:
- Fully compatible with existing validators;
- Gradual rollout without disrupting network operations.

Conclusion
BBM represents a significant step forward in Solana’s infrastructure, delivering:

- Fairer revenue distribution;
- Improved network efficiency;
- Better conditions for all ecosystem participants.

Precise efficiency metrics will be published upon completion of testing.

@jaxx_io @AttentionToken I think all @jaxx_io users primarily want to see BCC support. Am i wrong? 😑
