This BEP describes how to have a better understanding of the origin of a transaction with a special field in a transaction for recording its source.
By adding a field in each transaction message, the origin of any transaction could be tracked.
This BEP is already implemented.
BNB Beacon Chain is designed to connect with multiple service providers, such as different wallet providers and trading platforms. By adding an optional field in each transaction message, the origin of any transaction could be tracked. This proposal does not want to deal with assigning the values for various source types. The different sources will claim different value and such a proposition will be assigned afterwards.
The transaction is a standard way to wrap a message with signatures.
| Field | Type | Description |
|---|---|---|
| Msgs | message | transaction message |
| Sig | signature | signatures from the account holder |
| Memo | string | some notes come with the transaction |
| Source | int64 | where does this transaction come from |
| Data | byte[] | transaction data |
- Service Provider choose their own source identifier
- They have to create a PR to BEP-10 and add their identifier code in the form under section 5.3
- Maintainer review their PR
- If the PR gets accepted, this new identifier will be recognized
These are the registered source types.
All of these constant values shall be considered hardcoded in client implementations.
