CRC1155 NFT 教程

本教程将指导您逐步完成在Conflux CoreSpace上使用Hardhat创建、编写和部署ERC1155 NFT智能合约的过程。 此外还将向您展示如何在ConfluxScan上查看您的合约。 您可以在Conflux-NFT-CRC1155 仓库中找到一个实际的例子。

CRC20 代币跨空间(Cross Space)转移

This tutorial guides developers on transferring any CRC20 token from Core Space to eSpace, The goal is to transfer a CRC20 token (A) issued on coreSpace to become an ERC20 token (eA) in eSpace. Currently, if there is no corresponding token in eSpace, it's not possible to use the official cross-space bridge directly.

智能合约

智能合约可以理解为一个运行在Conflux Core 链上的程序。 它是位于 Conflux Core 链上的一个特定地址的一系列代码(函数)和数据(状态)的集合。 想要进一步了解智能合约,请参考我们的智能合约介绍。

概览

Conflux Core Space 是 Conflux 网络的原生空间。 得益于 Conflux 创新的树图账本结构以及共识算法,Core Space 在不牺牲去中心化的前提下拥有远超比特币和以太坊的性能。 这为 Conflux 生态系统的发展提供了有力支持。

虚拟机的差异

Core Space 的虚拟机在大多数情况下与 EVM 兼容,但存在一些差异。 本页列出了两者之间的差异。

默克尔树白名单

Using a Merkle Tree whitelist provides a cost-efficient way to distribute NFTs to a predefined list of addresses. It ensures that only whitelisted addresses can mint the NFTs, enhancing security and efficiency. Writing a whitelist of thousands of addresses directly within a smart contract would result in significant gas costs, and additionally, due to the maximum transaction gas limit restriction, it might be impractical to update such a large whitelist in a single transaction. However, since in the Merkle Tree verification process, leaf nodes and proofs can be stored off-chain while only the root value needs to be stored on-chain, this method significantly saves on gas costs and enables whitelist setup with only one transaction.
