user71277: I have a complete blockchain but when I set rescan = 1 in .conf file my bitcoind starts rescaning from 435000 block. How to start it from the first block? What's wrong with my blockchain?

user51948: As of Bitcoin Core v0.16 and later, it is recommended to rescan the blockchain using the rescanblockchain RPC rather than the -rescan parameter (which will be removed in the latest release). The default start height of this RPC is 0, so you can simply run rescanblockchain with no parameters to rescan the entire chain.
