This page compares Anoma's resource model with the account and UTXO model. |
The advantages of the resource model are best understood by comparison with other widely used state models: the account model and the UTXO model.
| Resource Model | UTXO Model | Account Model | |
|---|---|---|---|
| State Representation | Implicit | Implicit | Explict |
| State Scope | Local, fragmented among resources | Local, fragmented among UTXOs | Global, unified across all accounts |
| State Updates | Consumption & creation of resources | Consumption & creation of UTXOs | Direct modification of global state |
| State Lookup | Aggregation of resources (e.g., by kind or owner) | Aggregation of UTXOs (e.g., by owner) | Direct lookup in the account |
| Logic Predicates | Arbitrary logic per resource | The same logic for each UTXO | Arbitrary logic per account |
| Apps | General application & intents | Limited applications (e.g., payments) | General applications |
| App Distribution | Consumption & creation of resources | Consumption & creation of UTXOs | Account deployment to an address to each chain |
| Used by | Anoma | Bitcoin, Zcash | Ethereum, Solana, Cosmos, Polkadot |
