This is an implementation of a DNSSEC oracle for Ethereum. With it, you can securely prove the contents of any DNSSEC-signed DNS record on the Ethereum blockchain, as long as it was signed using supported public key schemes and digests. Presently, the oracle only supports RSA and SHA-256; fortunately, over 3/4 of TLDs use this combination of algorithms.
Once a record is proven to the oracle, any contract or external caller
can fetch it with the rrsets
constant function, allowing other
contracts to read data from DNS.
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.
The DNSSEC Oracle uses npm to manage dependencies, therefore the installation process is kept simple:
npm install
The DNSSEC Oracle uses truffle for its ethereum development environment. All tests can be run using truffle:
truffle test
To run linting, use solium:
solium --dir ./contracts
npm install dnssec-oracle --save
import "dnssec-oracle/build/contracts/DNSSEC"
var data = require("dnssec-oracle/build/contracts/DNSSEC.json")
The JSON file is same as the one generated using truffle compile
. You
can pass the loaded data to truffle-contract
or use it via web3 by
passing data.abi
.
A command line utility is available that automates the task of generating the necessary proofs from DNS data and submitting them to the oracle.
The oracle is still in alpha, and does not yet have any official deployments on the main network or test networks.
