I have programmed a block explorer in Java, but it is not yet finished.
The project is not yet on Github etc.
In principle, you can look for everything in the blockchain, for any sign in certain calculation, or after lengths, according to the same "R" etc.
If you can do a little Java, you can program your own search cries.
- The blockchain must be available locally.
- The blockchain is then copied to its own database, takes a while and need a lot of space.
So if you are interested, just write to me.
When you say the blockchain is available locally, do you mean a copy of Bitcoin Core's block data must be available beforehand?
And then the copying - how much extra space does it need on top of that, in gigabytes? Does it just harvest the blocks folder of some full nodes and then converts it into its own format?
