Is there a way to disable a blockchain validation? I installed Bitcoin Full Node on Raspberry pi 3b+. Blockchain sync is dead slow because of less CPU. I Guess blockchain validation is time/CPU consuming thing. Is there a way to disable the validation and just download the chain? I understand the consequences. If my peers send wrong data, I will end up using wrong data. But I don't have an alternative. RPC calls are dead slow right now. I just need data to write some code.
It you just want to test your code with the Bitcoin Core RPC calls, you can use regtest mode by starting Bitcoin Core with -regtest. This mode sets up a private testing network so there is no need to sync the blockchain or connect to other peers unless you set up other peers to connect to. You can mine your own blocks in this mode too so blocks are produced when you want them.
