Account centric models are inherently faster. Ethereum operates on a global account based model. This means a global lock occurs any time someone needs to touch a piece of global state, such as an ERC20. An account centric model, instead, creates a new deterministic address or state for each account. This means calls into transfers on ERC20s and dexes can be made in parallel, accelerating speed drastically. It also is more secure. It’s a forgotten mechanism to scale ETH.
