EVM深度分析之数据存储(一)

Storage是一个可以读写修改的持久存储的空间,也是每个合约持久化存储数据的地方。 Storage是一个巨大的map,一共2^256个插槽,一个插糟有32byte。 EVM提供的用于操作storage的指令有两个:

详解以太坊虚拟机(EVM)的数据存储机制

以太坊智能合约虚拟机(evm)是其区块链网络的核心组成部分,负责执行智能合约的逻辑。evm是一个图灵完备的虚拟机,为开发者提供了一种在以太坊网络上编写、部署和执行智能合约的平台。在本文中,我们将深入探

深入理解EVM

声明为存储(storage)的的合约变量分为两种,定长变量和不定长变量。 我们着重研究一下前者,看看EVM是怎么把定长便利那个装进32字节的插槽里的。 关于不定长变量可以看一下 "Program

WeaveVM''s solution to the EVM world state growth bottleneck

The central data structure governing accounts, balances, code, and contract storage in an EVM-based blockchain is the world state trie. The effective management of this data structure is a pivotal concern in scaling these blockchains.

Hitchhikers Guide to the EVM. Gas Golfing by Optimizing Storage

To understand how we can optimize structs, let''s dive into storage slots and value types a little deeper. Storage. Storage slots are 32 bytes each; Every single slot incurs an SLOAD or SSTORE...

Scaling the EVM from First Principles: Reimagining the Storage

The EVM''s storage layer faces a critical challenge: storage operations require expensive hash recomputations through the MPT, making them costly and resource-intensive. As smart contracts proliferate, growing state size increases computational complexity and storage requirements, making network participation increasingly difficult with consumer

Understanding the Ethereum Virtual Machine (EVM): A Deep Dive

In this article, we''ll explore the key components of the EVM, including the stack, memory, storage, gas, Solidity, Ethereum versions, and variable sizes. The Stack: The EVM''s Workspace

Store and Memory Management in EVM

Memory: The EVM provides a temporary memory space for smart contracts to store data during execution. Memory is organized in bytes and can be dynamically allocated, allowing contracts to handle complex data structures. Storage: The EVM provides persistent storage for smart contracts in the form of a key-value store. Each contract has its own
