Metis: Streaming Full Historical Blockchain Data

The Metis blockchain is a Layer 2 scaling solution for Ethereum that uses Optimistic Rollups to improve scalability, reduce transaction costs, and enhance usability for decentralized applications. It aims to create a decentralized, community-governed ecosystem that facilitates the development of decentralized autonomous companies (DACs) and supports a wide range of DeFi applications.

Tables include:

- Approvals: This table stores vital information regarding permissions granted for actions executed on the blockchain, such as token transfers or interactions with non-fungible tokens (NFTs).<br/>
- Blocks: Blocks are where batches of transactions are processed together. This table provides all the details about the block activity.<br/>
- Logs: A collection of log records and most importantly they contain events. A single log record includes both topics and data. Topics is a list that includes the signature of the event as well as any indexed fields. A single log record can have up to four topics in it. Logs contain events, where smart contracts have the ability to "emit" events during execution.<br/>
- Priced Net Transfers: Curated table of transfer "events" for a digital asset. They include all transfers including the native token, erc20s, and other token types. This table has converted all the values using token metadata and have priced historical asset value to USD. The difference of the net table vs the standard priced table is that the transfers are broken up into in-flow and out-flow based on the sending and receiving parties. It's useful when evaluating transfers from a party: wallets, exchanges, and smart contracts.<br/>
- Priced Transfers: Curated table of transfer "events" for a digital asset. They include all transfers including the native token, erc20s, and other token types. This table has converted all the values using token metadata and have priced historical asset value to USD.<br/>
- Receipts: Provided for transactions to know the status of a transaction. SonarX uses the receipts data to identify successful vs failed transactions.<br/>
- Tokens: Curated metadata that identify the key properties of a token and identify the token type.<br/>
- Token Transfers: Provides information about token transfers, including transaction hash, sender, recipient, token type, amount, and timestamp.<br/>
- Transactions: Contains only successful transactions and contain details including the amount of native token and gas which was used in the transaction.<br/>
- Transactions Failed: Contains only failed transactions which are identified by the transaction receipt status.

Metis区块链（Metis blockchain）是面向以太坊（Ethereum）的第二层扩容方案，采用乐观rollup（Optimistic Rollups）技术以提升系统可扩展性、降低交易成本，并优化去中心化应用的使用体验。其核心目标是构建去中心化、社区自治的生态系统，推动去中心化自治公司（decentralized autonomous companies，简称DACs）的开发，并支持广泛的去中心化金融（DeFi，Decentralized Finance）应用。更多详情可访问[www.sonarx.com](https://www.sonarx.com/)。

数据集包含以下表格：

- 授权表（Approvals）：该表存储区块链上各类操作的授权相关关键信息，例如代币转账或与非同质化代币（NFT，non-fungible tokens）的交互。
- 区块表（Blocks）：区块是批量处理交易的载体，该表完整记录并提供区块活动的全部细节信息。
- 日志表（Logs）：该集合存储各类日志记录，其核心内容为事件信息。单条日志记录同时包含主题与数据两部分，其中主题为包含事件签名及所有索引字段的列表，单条日志最多可包含4个主题。日志承载智能合约在执行过程中可触发的各类事件。
- 计价净转账表（Priced Net Transfers）：针对数字资产转账事件整理的专用数据表，涵盖原生代币、ERC20代币及其他类型代币的全部转账记录。该表通过代币元数据完成数值转换，并将历史资产价值折算为美元。与标准计价转账表的区别在于，本表格根据交易双方的收发属性，将转账拆分为流入与流出两类，适用于从钱包、交易所、智能合约等特定主体视角评估转账行为的场景。
- 计价转账表（Priced Transfers）：针对数字资产转账事件整理的专用数据表，涵盖原生代币、ERC20代币及其他类型代币的全部转账记录。该表通过代币元数据完成数值转换，并将历史资产价值折算为美元。
- 交易收据表（Receipts）：用于查询交易状态的数据集，SonarX通过该表的数据区分交易成功与失败的情况。
- 代币元数据表（Tokens）：用于标识代币核心属性与类型的整理后元数据集。
- 代币转账表（Token Transfers）：提供代币转账相关的详细信息，包括交易哈希、发送方地址、接收方地址、代币类型、转账金额及时间戳。
- 成功交易表（Transactions）：仅收录成功完成的交易，包含原生代币数量、交易消耗的Gas等详细信息。
- 失败交易表（Transactions Failed）：仅收录通过交易收据状态识别出的失败交易。
