Account Based Model

The account-based model, popularized by Ethereum, treats the ledger as a state machine where each address has a specific balance that is updated directly during transactions. This model is generally more intuitive for developers building complex smart contracts, such as those required for options and decentralized derivatives.

It allows for simpler logic regarding state changes, such as checking collateral levels or executing margin calls. However, it can lead to state contention, where multiple transactions attempt to update the same account simultaneously, requiring careful gas management and sequencing.

This model is the foundation for most programmable money platforms, influencing how derivative protocols manage liquidity and user accounts.
