Here is my list of 43 (mostly) reviewed Bitcoin forks (+3 Bitcoin Cash forks).
This list is not comprehensive, I am not adding anymore forks that I newly learned about that very clearly have just a website (and maybe an old source code) and never really took off, it would be just a waste of my time.
Feel free to suggest a bugfix, addition or any other improvement.
The difference between this list and most of the other lists is that I personally compile the source code, run the software, sync or import all the shared pre-fork blockchain data (using
the method I described here, if possible - almost always is), sync-up the blockchain, replace wallet.dat with my Bitcoin Core's encrypted wallet.dat, zap/rescan the wallet and verify that my balances are properly present. Since I never import any private key (and so far never made a since transaction on any of these new forks, thus never unencrypted and revealed my keys) even if the software is evil and would like to babble out the private keys it can't.
I am only interested in forks with full-node source code based on Bitcoin Core. If all this checks out I deem the fork as "
seems to be working". Aferwards I prune the blockchain up to the fork block by starting the daemon with "prune=1" and then issuing an RPC command "pruneblockchain <forkblock>" as the pre-fork blockchain data is not necessary anymore. That way we can see how much the fork's blockchain actually grew since its inception and that (the size of the "blocks" directory) is what the GB amount indicates.
(Last update: February 26th, 2019)Total number of reviewed Bitcoin forks: 43 of which
-
seem to be working: 16 (214.59 GB)
-
first worked then stopped (and possibly disappeared): 5 (10.22 GB)
-
seem to have no nodes: 1 -
haven't published full-node source code based on Bitcoin Core: 11 - seem like a waste of my resources to compile/sync/test (sorry): 3
-
seem abandoned: 2 -
don't seem to exist (anymore): 5Total number of reviewed Bitcoin Cash forks: 3 (5.89 GB)
