This repository host the attestation libraries TokenScript. Discussion goes to the forum https://community.tokenscript.org/
In short, an attestation can be likened to a token created off-chain and usable on-chain. An example of an attestation would be a Devcon ticket. See document here: http://tokenscript.org/Attestation.html
You need the following installed:
- JDK (version 11 or higher)
- Gradle (version 7.1.1 is used by our devs)
- node.js (version 15 is used by our devs)
Once you have them installed, run:
$ gradle build
The build script will run a few tests, resulting a few pem files created in build/test-results/ directory.
To create a jar file for running the demo, run:
$ gradle shadowJar
Which will create a jar file that you can run in the commandline
build/libs/attestation-all.jar
There is a walk-through to use the functionalities provided by this library through commandline: commandline cheque demonstration and the commandline EIP712 attestation demonstration
This repository has the following content:
data-modules :the data modules definitions used in this project
src :the implementation of the attestation and protocols. We use a Java-Solidity model for quick prototyping - testing.
ethereum/lib : lib for smart contracts which uses attestations
ethereum/issuers : example smart contracts used by issuers, for example, revocation list management.
ethereum/trustlist : members of trustlists to be adopted by smart contracts
ethereum/experiments : work not in the published specifications
ethereum/example-james-squire : an example to be used in your projects which requires attestations
paper : the paper behind the design of this project. The current version there is dated (2018) and doesn't reflect the new work in the last a few years. The current focus is the cheque/attestation protocol
