Blockspace Forum
Forum built to improve the Ethereum transaction journey.
Education, research, and open source tooling for the infrastructure that moves Ethereum's transactions. This forum ships.
Every 12 seconds, Ethereum produces blockspace
Blockspace is scarce, verifiable compute and data inside each block. It's what every transaction, contract call, and L2 settlement competes for. Understanding how it's produced, priced, and allocated is the starting point for understanding Ethereum's infrastructure.
Start learning→How your transaction becomes a block
Over 90% of Ethereum validators outsource block construction to a specialized pipeline: searchers bundle transactions, builders assemble full blocks, and relays facilitate the auction of blockspace between builders and validators. Each handoff is a design decision with tradeoffs that shape what ends up on chain.
Understand the pipeline→Three years of production exposed four structural gaps
Economics
Exclusive order flow concentrates block construction among a few builders. The auction selects the best-connected builder, not the best block. Relays lack sustainable revenue, leading to counterproductive workarounds.
Robustness
Winner-take-most dynamics shrink the active builder and relay set, raising correlated failure risk from implementation monocultures, shared infrastructure, and jurisdictional pressure.
Performance
The pipeline lacks scheduling or deadline mechanisms. Users overpay to hedge unpredictable inclusion, and the 12-second slot leaves a UX gap against faster chains.
Services
Validators forfeited their say in block building and became price takers. There is a desire to restore autonomy but missing rails.
Forum built to improve the Ethereum transaction journey.
Research
Identify the problems precisely and design solutions grounded in mechanism design, game theory, and data. Publish openly so the entire community can scrutinize and build on the work.
Ship
Working with the community to ship the open source infrastructure and specs that turns research into production.
Published research
Analysis from Blockspace Forum contributors identifying problems and designing solutions.
How do I get involved?
Blockspace Forum is an open community. We meet to share research, build tooling, and push the blockspace pipeline forward. Whether you're a validator operator, protocol researcher, or just getting started, there's a place for you.
Coming soon
We are working with the community to catalog open source infrastructure for the transaction pipeline. Check back soon.
