Fantom: Streaming Full Historical Blockchain Data

Fantom is a DAG based Smart Contract platform that intends to solve the scalability issues of existing public distributed ledger technologies. The platform intends to distinguish itself from the traditional block ledger-based storage infrastructure by attempting to employ an improved version of existing DAG-based pro-tocols. The Fantom platform adopts a new protocol known as the “Lachesis Protocol” to maintain consensus. This protocol is intended to be integrated into the Fantom OPERA Chain. The aim is to allow applications built on top of the FANTOM OPERA Chain to enjoy instant transactions and near zero transaction costs for all users. The mission of Fantom is to provide compatibility between all transaction bodies around the world, and create an ecosystem which allows real-time transactions and data sharing with low cost.

Tables include:

- Blocks: 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/>
- Traces: Provided on archive nodes and store every function call that is emitted on the blockchain.<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/>
- Token Transfers: Provides information about token transfers, including transaction hash, sender, recipient, token type, amount, and timestamp.<br/>
- Traces No Transactions: Stores detailed records of execution traces that do not belong to transactions.<br/>
- Decoded Logs: A decoded representation of blockchain event logs, offering comprehensive insights into individual events recorded within each transaction.<br/>
- Decoded Traces: A decoded representation of the input and output data of the function call in the traces.
