[Cryptography] Security model of blockchains ?

[John Levine]

Have there been any good papers on the security model of blockchains?
I'm thinking of stuff like collusion, network partitioning, miners
losing interest or being bribed, and of course latent software bugs.
In some cases it's not obvious to me how you'd even tell that an
attack was happening until much later.

Any references appreciated.

R's,
