       This is your periodic reminder that not all blockchains are cryptocurrencies and not all cryptocurrencies are blockchains.

       @steko Haha, I actually made the post before I read it, but it was actually not about that!  It was about the conversation about "stamps" on the fediverse, and peoples' default assumption that this means blockchains

       @cwebber @alexl hmm, what's our working definition of a block chain? I would have disqualified git since it tolerates branching. Does any merkle dag count as a block chain? Also, another example: stellar, a crypto currency with no block chain.

       @zenhack @alexl And yes, "blockchain" is sufficiently vague that I think any merkle tree appliesI frequently comment that "blockchain" is the "cloud" of merkle trees ;)

       @cwebber @alexl I guess this feeds into the point that block chain is just a buzzword by now. I suppose I'd been assuming proof of work as a criterion too. Iirc the stellar docs don't talk about block chains at all. But from a marketing standpoint that probably helps then differentiate, since their whole schtick is about how they don't have some of Bitcoin's glaring problems.

       @zenhack @alexl @cwebber Requiring PoW is a bit too narrow, but some form of distributed consensus mechanism should be part of the blockchain to make it meaningful as a concept beyond any old Merkle chain.
