world state

Every Ethereum transaction modifies the world state, updating account balances and contract storage.每一笔以太坊交易都会修改全局状态，更新账户余额和合约存储。

The world state is represented as a Merkle Patricia Trie, allowing efficient verification with compact cryptographic proofs.全局状态表示为默克尔帕特里夏树，允许通过紧凑的密码学证明进行高效验证。
