Resources committed exclusively to a _single_branch_ of the block chain in any fork are the key to any block chain security (including proof-of-stake) that doesn't immediately fail.

The only thing I can come up with that is limited in the way that committing it to a single branch would be meaningful, is transactions. And that's why I advocate transactions-as-proof-of-stake.

Does Reddcoins Proof of Stake Proof / Proof of Velocity fit transactions-as-proof-of-stake?
FWIW, Factom is plannig to use the same or similar PO* model.
