Polkadot: Streaming Full Historical Blockchain Data

Polkadot is a platform that allows diverse blockchains to transfer messages, including value, in a trust-free fashion; sharing their unique features while pooling their security. In brief, Polkadot is a scalable heterogeneous multi-chain technology. Polkadot is heterogeneous because it is entirely flexible and makes no assumption about the nature or structure of the chains in the network. Learn more at [www.sonarx.com](https://www.sonarx.com/)

Tables include:

- Blocks:  Batches of transactions are processed together. This table provides all the details about the block activity.<br/>
- Events: Contains records of events that occurred on the Polkadot network, including information about transactions, smart contract executions, and other on-chain activities. These events provide insights into the network's state changes and interactions.<br/>
- Extrinsics: Stores data related to extrinsic actions, which are the transactions or operations submitted to the Polkadot network. This table includes details about who initiated the extrinsic, its type, and parameters, making it valuable for analyzing on-chain actions and transactions.<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 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/>
