Bitcoin XT. Most recent release is K.
Bitcoin XT is an implementation of a Bitcoin Cash (BCH) full node that embraces Bitcoin's original vision of simple, reliable, low-cost transactions for everyone in the world. Bitcoin XT originated as a series of patches on top of Bitcoin Core and is now a independently maintained software fork. See some selected features.
Bitcoin XT downloads are code signed and are built reproducibly using gitian. Discussion can be found at the XT Gitter.
If using a data directory from a different BCH or BTC full node, specify
-reindexon first launch.
wallet.datfrom Bitcoin Core or Bitcoin ABC (reason: HD wallet not yet supported). Also delete
fee_estimates.datfrom these clients.
Bitcoin XT can run in BTC chain mode by specifying
-uahftime=0. Please note that Bitcoin XT does not validate segwit, and the conversion notes above still apply.
Ideas for useful features are tracked in Issues. Pull requests from developers, including well-done cherry picks from other clients or cryptos, are very welcome.
