Composability is the ability of components within a system to be reliably retrieved and recombined into larger assemblages. In the context of decentralized finance (DeFi), composability is a quality of the Ethereum ecosystem and is deemed crucial to the interoperability of crypto-finance protocols such as UniSwap.
'Atomic', in this context, means that any command executed across multiple components will execute as a unitary command that either wholly succeeds or fails.
Atomic composability [ /əˈtɑmɪk kəmˌpoʊzəˈbɪlɪti/ ] is an impediment for DeFi scaling solutions that employ sharding because of the communication between shards needed to maintain a global network state. Cerberus, Radix’s consensus mechanism, overcomes this by employing a deterministic, hash-indexed shardspace and by enabling shards to temporarily ‘braid’ the components (’substates’) of a transaction together.
Research by RDX Works has found that 69% of all Ethereum transactions utilize some degree of atomic composability.
The Radix Programmer's Guild
RadGuild is a member-directed community of designers and developers who are building core software building blocks (aka blueprints) and key distributed applications (aka Dapps) for the Radix Decentralized Ledger which we believe will emerge as the key enabling technology for the free world's digital economy.
