#EVM (以太坊虚拟机)和#BVM
( Bitcoin virtual machines ) are both virtual machines designed to execute smart contracts on the blockchain, but their structures and design philosophies differ. Let's take a brief look at the comparison!
Purpose and Design Philosophy
EVM: The Ethereum Virtual Machine is dedicated to simplifying the process for developers to write smart contracts and build various decentralized applications ( DApp ). Therefore, it is a general-purpose virtual machine that supports complex computations and conditional logic.
BVM: BVM aims to execute TBC smart contracts and is an extension of the Bitcoin UTXO model. Unlike Ethereum, which emphasizes complex smart contract functionalities, BVM focuses more on efficient and secure execution.
2□State Management
EVM: uses an account-based model to manage all account states, including balances, contract data, etc. Smart contracts can access and modify states to achieve more complex functionalities.
BVM: A UTXO model based on Bitcoin, which does not have a global state. The state is retained only when the UTXO is unused, so the state management of smart contracts is relatively limited.
3 Smart Contract Function
EVM: Ethereum smart contracts can execute complex logic, such as loops, making them very suitable for developing various DApps.
BVM: By expanding the script system, BVM has added more operation codes, supporting basic smart contract functions. However, complex logic will face more limitations. The cost is higher security and execution efficiency.
4 Parallel Processing
EVM: Sequential execution in a single-threaded environment makes parallel processing difficult.
BVM: Thanks to the UTXO model, it can achieve parallel processing, thereby increasing transaction throughput.
Abstract
EVM: General and able to support complex smart contracts.
BVM: Limited functionality, but based on Bitcoin, focusing on efficiency and security.
