Editing Dumb contracts (section)

== Examples of decentralized autonomous systems. ==

* '''Bitcoin (and most cryptocurrencies)''' – Gives rewards for solving hash-based puzzles to facilitates consensus, allowing the movement of assets to be accurately maintained in a shared ledger – no human input or verification needed as this is all based on cryptographic proof.
* '''Namecoin''' – Runs on a standard blockchain and allows for registering domain names which can be queried on the blockchain for their IP address. The system is more useful when combined with standard DNS so that domains are accessible without installing Namecoin.
* '''Datachains''' – Full disclaimer: my speculation. Arbitrarily specialized AIs that are downloaded by peers to find patterns in scattered data sets. New assets in the system would be given to participants for finding matches which would be publicly verifiable so that the structure would function similar to a blockchain but would use collateral in a two-way-peg to mitigate spam and a hybrid PoW for security.
* '''Timechains''' – Full disclaimer: some of my work. Timechains create a time-lock encrypted chain of public keys which release rewards when broken. The public keys can be used to encrypt information so that the information is released in the future without human involvement.

Note: This last one may not be a good example of a DAS as a timechain requires initial trust in the person who stitches the chain together – but after the timechain is setup it requires no further human involvement to provide its basic functionality so it operates as a DAS.
