kernel: update chainTxData
What changed, and why it matters
This commit updates routine network statistics in Bitcoin Core's chain parameters. It refreshes the recorded time, total transaction count, and transaction rate for mainnet, testnet, signet, and regtest networks based on recent blockchain data. There is no security issue here—this is normal maintenance data that helps the software estimate sync progress and blockchain size.
No security action needed. This is a routine data-maintenance commit. Reviewers may verify the updated values match the cited block hashes via getchaintxstats RPC if desired.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The patch updates ChainTxData constants in src/kernel/chainparams.cpp for CMainParams, CTestNetParams, CSignetParams, and CRegTestParams. These values (nTime, tx_count, dTxRate) are used by the node for progress estimation during initial block download and assume-valid chainstate sizing. The values are derived from getchaintxstats RPC output at fixed block heights. No code logic, validation rules, consensus behavior, or cryptographic checks are modified.
