Instant settlement is harming crypto capital efficiency

Ethan Buchman, co-founder of Cosmos and an early developer of the Tendermint consensus engine, warned in recent industry appearances that instant on-chain settlement is reducing capital efficiency in crypto markets.

He argued that when transactions settle immediately on-chain, counterparties must hold the full value of trades in the exact ledgers where those trades occur. That requirement increases idle or duplicated capital across chains and trading venues and prevents the netting of offsetting positions.

Under legacy settlement systems, clearinghouses and settlement windows let firms aggregate and net multiple transactions, cutting the cash or securities that must change hands. Many crypto systems aim for finality at the moment of trade, which removes counterparty credit risk while removing the ability to offset positions before settlement.

Buchman highlighted that outcome as a driver of higher capital requirements for market makers, decentralized finance protocols and cross-chain utilities.

Instant finality can fragment liquidity. If assets must be available on a particular chain at the time of trade, liquidity providers are incentivized to hold the same asset in multiple places. That duplication raises the total capital committed to support trading across the ecosystem, especially for tokens that move across many layer-1 chains and bridges.

Market makers and automated market makers may need larger capital buffers to quote continuously on multiple chains. Lending protocols and liquidity pools face limits on reusing collateral because assets locked for one settlement instance cannot be pledged elsewhere at the same time. Cross-chain settlement tools and bridges can move liquidity but introduce security and custodial risks that can reduce usable capital.

Participants and developers are testing technical and market approaches to narrow the efficiency gap. Layer-2 solutions and payment channels allow many off-chain exchanges before finalizing fewer on-chain settlements, which can reduce collateral needs. Credit lines, trusted settlement rails and centralized or federated clearing arrangements can reintroduce netting among trusted counterparties.

Some protocols are experimenting with pooled custody and virtual liquidity to let end users see instant clearing while back-end systems complete broader settlement optimizations. Others focus on interoperable asset standards and improved bridge security to lower the cost of shifting liquidity between chains.

Buchman co-founded Cosmos and helped develop Tendermint. His comments reflect an ongoing debate in the crypto sector about whether to prioritize immediate finality or to design systems that allow more post-trade aggregation to reduce capital needs.
