        @bascule Nice post, although SCP is dead on arrival. It has no real mechanism to prevent forks. Very dangerous.

        @bascule Forks seem likely, and once they occur reconciliation seems impossible.

        @taoeffect Bitcoin has exactly that problem (losing accepted writes/transactions in forks). At least SCP requires a quorum to accept a write

        @bascule Bitcoin does not have the problem I am describing at all. Bitcoin has a way of defining "truth", whereas SCP does not.

        @taoeffect Bitcoin loses acknowledged writes. From a CAP theoretic perspective, it sacrifices partition tolerance:http://codahale.com/you-cant-sacrifice-partition-tolerance/ …

        @taoeffect that's saying that to tolerate faulty networks (or faulty clients), systems *must* be partition tolerant. Bitcoin isn't.

        @bascule Why do u say after partition transactions on losing fork are lost? Won't they be incorporated into new blocks? Except double spend.

        @jiceman no, any transactions in an orphan block or fork are irrecoverably lost

        @bascule Nothing looks at the orphan block to ID tx's not in other blocks and to return those to mempool for inclusion in another block?

        Replying to @jiceman

        @jiceman no, nor is there a merge algorithm defined. Clients have to replay transactions and assume they’ll be included in subsequent blocks

        @bascule And, in that case, isn't this "sacrificing consistency" for availability? Or, am I missing something?

        @jiceman since Bitcoin loses accepted writes, it's just broken. It is neither consistent, CAP-available, or partition tolerant
