Spritely project ( https://spritelyproject.org/ )

Yes i'm following this project it's really interesting though i have a very weak understanding of how such "secure remote computation" can take place.

blockchain, allows for a form of distributed provable computation

Well a blockchain is merely a linked list of data. This data can contain programs/contracts as Ethereum is doing, however who gets to decide what block is next on the chain is up to individual implementation and their own trust model (usually majority wins).

The least-authority (permissionless, or anarchist) alternative is the DHT. Distributed Hash Tables are decentralized databases, but contrary to blockchains they are not an ordered list of items (with restriction on how to push something) but a loose collection items anyone in the network can publish.

Examples of DHTs include: Bittorrent, IPFS..

But the crucial bit is that a blockchain is public-key-signed transactions on top of a DHT. So I might not be able to make a particular transaction happen on a blockchain, but if it lists a transaction as having occurred then it did occur. So it doesn't prove everything and it can do things (good, bad, or neutral) in addition to proofs, but the things it lists as proved are actually proved.
