Alguien ha cogido el BIP 148 propuesto por shaolinfry y ha hecho un
fork (en el sentido de código fuente
) de bitcoin core implementándolo. En
bitnodes se puede ver que ya hay unos cuantos nodos ejecutando este código. Ahora no sale pero antes había uno de Barcelona, gracias!!
Me he bajado el fuente de core y el de core+bip148:

Cambié a la rama 0.14 en ambos repositorios:
$ cd bitcoin-core
$ git checkout 0.14
Branch 0.14 set up to track remote branch 0.14 from origin.
Switched to a new branch '0.14'
$ cd ..
$ cd bitcoin-UASF
$ git checkout 0.14
Branch 0.14 set up to track remote branch 0.14 from origin.
Switched to a new branch '0.14'
$ cd ..
Comprobé las diferencias entre core y core+bip148:
