Ethereum Classic: Streaming Full Historical Blockchain Data

Ethereum Classic is a decentralized, open-source blockchain platform that runs smart contracts. It originated from a split in the Ethereum blockchain following a disagreement over a hard fork intended to reverse a major hacking incident. Ethereum Classic retains the original Ethereum code, emphasizing immutability and "code is law" principles. It enables developers to build and deploy decentralized applications (dApps) while providing a secure and transparent ledger for transactions. Learn more at [www.sonarx.com](https://www.sonarx.com/)

Tables include:

- Blocks: Blocks are where batches of transactions are processed together. This table provides all the details about the block activity.<br/>
- Logs: 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/>
- 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.<br/>
- 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/>
- Tokens: Curated metadata that identify the key properties of a token and identify the token type.<br/>
- Decoded Logs: A decoded representation of blockchain event logs, offering comprehensive insights into individual events recorded within each transaction.
