The Status module that consumes go-ethereum
https://status.im
a2ff03c79e
Extends wallet module with the history package with the following
components:
BalanceDB (balance_db.go)
- Keeps track of balance information (token count, block, block timestamp)
for a token identity (chain, address, currency)
- The cached data is stored in `balance_history` table.
- Uniqueness constrained is enforced by the `balance_history_identify_entry`
UNIQUE index.
- Optimal DB fetching is ensured by the `balance_history_filter_entries`
index
Balance (balance.go)
- Provides two stages:
- Fetch of balance history using RPC calls (Balance.update function)
- Retrieving of cached balance data from the DB it exists (Balance.get
function)
- Fetching and retrieving of data is done for specific time intervals
defined by TimeInterval "enumeration"
- Update process is done for a token identity by the Balance.Update function
- The granularity of data points returned is defined by the constant
increment step define in `timeIntervalToStride` for each time interval.
- The `blocksStride` values have a common divisor to have cache hit
between time intervals.
Service (service.go)
- Main APIs
- StartBalanceHistory: Regularly updates balance history for all
enabled networks, available accounts and provided tokens.
- GetBalanceHistory: retrieves cached token count for a token identity
(chain, address, currency) for multiple chains
- UpdateVisibleTokens: will set the list of tokens to have historical
balance fetched. This is a simplification to limit tokens to a small
list that make sense
Fetch balance history for ECR20 tokens
- Add token.Manager.GetTokenBalanceAt to fetch balance of a specific
block number of ECR20.
- Add tokenChainClientSource concrete implementation of DataSource
to fetch balance of ECR20 tokens.
- Chose the correct DataSource implementation based on the token
"is native" property.
Tests
Tests are implemented using a mock of `DataSource` interface used
to intercept the RPC calls.
Notes:
- the timestamp used for retrieving block balance is constant
