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 number of transactions, timestamps, and transaction rates for mainnet, testnet, signet, and regtest networks based on recent blockchain data. There is no security issue here—this is normal maintenance data.
No action needed. This is a benign data-maintenance commit.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The change updates ChainTxData values (nTime, tx_count, dTxRate) across CMainParams, CTestNetParams, CSignetParams, and CRegTestParams in src/kernel/chainparams.cpp. These values are used for estimating blockchain size, sync progress, and fee estimation baselines. The values are derived from getchaintxstats RPC output at specific block hashes and are periodically refreshed as part of standard release preparation. No code logic, validation rules, or consensus behavior is modified.
