The ‘Source’ field provides information about where are the address labels (i.e. the address name and address entity name) from. The list of values available for this fields are provided in the table below:
| Value | Description | Example |
|---|---|---|
| Ground Truth | generated from: 1) direct interactions (transactions) with the labelled entity, or 2) official sources like OFAC or On-chain protocol page (e.g. Uniswap documentations) | Initiated deposit and withdrawals transactions against Binance to identify Binance addresses on chain. |
| Open Source | generated from external parties that are available to general public - e.g like Twitter, Discord, Etherscan, etc | Binance PoR addresses from Binance’s official website |
| Heuristics | generated from rule based approaches that are used to clusterize addresses on chain based on their transaction patterns - e.g. common-spend, core addresses, change, etc | Common-spend clusterizers running on Airflow for UTXO based chain - e.g. Bitcoin, Dogecoin |
| Machine Learning | generated from machine learning based models | |
| General On-chain Research | generated from analysis over historical transaction data available on-chain - these labels are not directly coming from external sources or rule-based model | VC addresses participated into Binance funding round - injections going into Binance’s addresses on-chain |
