| Essentially we use greenlets to make the IO layer async and the top layer uses async/await, but everything in | |
| between can be regular sync code. |
| /* | |
| Usage: | |
| 1. Account owner sends a request for verification, in this request he sends a fingerprint of his OpenPGP key stored on cryptonomica.net | |
| 2. This contracts sends back a string to sign | |
| 3. Accont owener signs this strign with his OpenPGP key and sends back to smartcontract. | |
| 4. Information about verification is public visible - who needs to check can download verified public key from cryptonomica.net and check if owner of stated Ehereum acconts is also known owner of verified OpenPGP key on cryptonomica.net | |
| It's also possible to create a web-inerface using Cryptonomica's API like: |
| /* | |
| This smartcontract is used to store documents text on the Ethereum blockchain | |
| and to get the document by document's hash (sha256). | |
| */ | |
| contract ProofOfExistence{ | |
| /* ---- Public variables: */ | |
| string public created; |
| pragma solidity ^0.4.15; | |
| contract StringsAndBytes { | |
| /* --- public variables for storing tests results */ | |
| string public lastTestStringResult; // | |
| bytes32 public lastTestBytes32Result; // | |
| bytes public lastTestBytesResult; // bytes: dynamically-sized byte array | |
| bool public lastTestBoolResult; // |
