Block Construction

Block construction is the technical process of selecting, ordering, and bundling transactions into a coherent block for network submission. This process involves complex optimization to ensure the block is valid according to protocol rules while maximizing economic return.

Builders analyze transaction fees, MEV opportunities, and network constraints to determine the optimal configuration. The construction process is time-sensitive, as blocks must be produced within a strict time window to maintain network performance.

It involves managing memory buffers, verifying transaction signatures, and ensuring all state transitions are correct. As block space is a scarce resource, the construction phase is highly competitive and driven by market incentives.

It is the point where theoretical MEV opportunities are transformed into realized profit. The efficiency of block construction directly impacts the latency and throughput of the entire blockchain.
