discard it and work on top of their empty block. (Remember, they are running an attack, not mining like everyone else)
SV chain would accept that block as valid yes. For a while.
When SV miners (attackers) working on top of their previous empty block (and not your block) find a new empty block on top - they send it to a ABC/SV chain - all clients recognise that
There won't be empty blocks. Too slow. @_opreturn
Easy fix: include their own transactions ordered with CTOR or include op_checkdatasig in one transaction in the block.
this (their empty) block has more accumulated proof-of-work than yours and orphan your block (discard it).
The longest chain in Bitcoin software is defined as "having most accumulated
proof-of-work".
Even if you don't believe that the network would orphan this block - SV would mine in some time future next empty block on top of their own network block. ""
