Blockchain smart-contracts in human language

Sawroom integrates the Zenroom VM to be used as a transaction processor in the Sawtooth blockchain distributed by the Linux Foundation's Hyperledger consortium.

To facilitate the creation of transaction families based on Zenroom and the Zencode human-friendly language for smart-contracts, the Sawroom TP uses the Sawtooth SDK in Python and the zenroom-py bindings.

Quick start

To try the Sawroom setup with a running Sawtooth is best to use the docker-compose inside docker-dyne-software repository:

git clone https://github.com/dyne/docker-dyne-software
cd sawroom
docker-compose up --build

Once all daemons are running, to run a transaction see:

docker exec -it zenroom-tp zenroom-tx --help

This will show you all the commands available from the zenroom-tx cli interface, which takes a Zencode script from stdin and sends its results into a transaction.

keygen

To send a transaction first generate a keypair using the keygen command

docker exec -it zenroom-tp zenroom-tx keygen FILENAME

transaction

docker exec -it zenroom-tp zenroom-tx transaction --help

Configuration

The only environmental configuration accepted is is ZTP_VALIDATOR_ENDPOINT.
