sidechainless

Sidechainless is a term used in blockchain discourse to describe architectures and scaling strategies that aim to avoid the use of separate sidechains for processing transactions or smart contracts. In a sidechainless approach, computation and state updates are conducted on the main chain (layer 1) or through layer-2 mechanisms that ultimately settle on the main chain, rather than on independent sidechains linked by bridges.

Designs labeled as sidechainless emphasize maintaining security and finality anchored to the origin blockchain. Common techniques

Advantages of sidechainless designs include a simplified security model, reduced cross-chain risk, and potentially smoother user
