1.blockscout

开源地址：https://github.com/poanetwork/blockscout

BlockScout是一个Elixir应用程序，允许用户搜索交易，查看帐户和余额，并验证整个以太坊网络上的智能合约，包括所有的叉子和侧链。

目前可用的块探测器（即Etherscan和Etherchain）是封闭系统，不能独立验证。随着以太坊侧链在私人和公共场合的不断扩散，需要透明的工具来分析和验证交易。

2.EthVM

开源地址：https://github.com/EthVM/EthVM

EthVM是一个开源的区块链浏览器，主要关注以太坊（虽然其他网络将受到支持）在MIT许可下，并以不同语言（即TypeScript，Kotlin和Solidity）的混合编写。

您可以使用EthVM作为工具来探索自定义专用网络或现有公用网络，或者作为ETL（提取，转换，加载）平台来对数据执行不同的分析。

5.etherchain-light

开源地址：https://github.com/gobitfly/etherchain-light

Etherchain Light是一个使用NodeJS，Express和Parity构建的以太坊区块链资源管理器。它不需要外部数据库，并从后端以太坊节点即时检索所有信息。

6.toy-block-explorer

开源地址：https://github.com/curvegrid/toy-block-explorer

基于以太坊支持数据隐私

 2021-02-26　  Surou　  阅读 　  Ethereum-开源推荐　  0 评论

官网：https://consensys.net/
开源地址： https://github.com/ConsenSys/quorum

详细介绍：https://rdc.hundsun.com/portal/article/892.html

Quorum是一个基于以太坊的分布式账本协议，具有交易/合同隐私和新的共识机制。

Quorum是go-ethereum的一个分支，并根据go-ethereum发行版进行了更新。

以太坊的主要增强功能：

  • 隐私-Quorum通过公共/私有状态分离来支持私有交易和私有合同，并利用对等加密消息交换（请参阅Constellation和Tessera）将私有数据定向传输到网络参与者

  • 替代共识机制-Quorum不需要在许可的网络中使用POW / POS，而是提供了多个更适合联盟链的共识机制：

    • 基于筏的共识-一种共识模型，可加快区块时间，完成交易并按需创建区块
    • Istanbul BFT-由AMIS启发，具有PBFT的交易最终性的共识算法。
    • Clique POA共识-与Go Ethereum捆绑在一起的默认POA共识算法。

  • 对等权限-节点/对等权限，确保只有已知方才能加入网络

  • 帐户管理-Quorum引入了帐户插件，该插件使Quorum或clef可以通过包括外部库在内的其他帐户管理方法进行扩展。

  • 可插拔架构-允许将其他功能作为插件添加到核心geth，从而提供可扩展性，灵活性和Quorum功能的独特隔离。

  • 更高的性能-Quorum提供的性能吞吐量比公共场所高得多
