This document introduces Agreements Network and their blockchain products Monax, Hyperledger Burrow, and Blackstone. Hyperledger Burrow is a permissioned blockchain that uses Tendermint consensus and supports the Ethereum Virtual Machine. Blackstone is a business process management tool that ingests BPMN files and converts them into process graphs that can run on Burrow. It allows modeling and executing business processes across companies on blockchain. The document demonstrates how to get started with Blackstone by installing Burrow, deploying Blackstone contracts, and starting the API.

BPM on Blockchain

2. Introduction
▶ Monax
▶ First to market with a Permissionable Blockchain -- now Hyperledger Burrow
▶ First to market with scalable systems of smart contracts -- now Blackstone
▶ First to position blockchain technology as enabler for legal -- now Agreements Network
▶ Overview of Hyperledger Burrow
▶ Overview of Blackstone
▶ Demonstration
▶ How to Get Started

3. Fast, easy, process-oriented blockchain client
Hyperledger Burrow

4. Hyperledger Burrow
▶ Tendermint Consensus Engine
▶ Permission layer and secure natives framework
▶ Built-to-spec EVM
▶ In-built tooling (configuration, deployment, monitoring)

5. 1. Single binary distribution with in-built tooling
2. Fast, simple and easy to use
3. Highly suitable for process-heavy use cases
Advantages of Burrow

6. BlackstoneFull-feature business process management in
Solidity

7. Blackstone
▶ High level API to ingest BPMN files and turn those into Solidity-based
process graphs. Full-feature business process modelling execution
engine
▶ Operating and managing business processes on a blockchain is
suitable for cross-company process tracking. NOT trying to replace
in-house BPM suites.
▶ Blackstone + Burrow allows for no-code blockchain-based
process-managed use cases

11. Systems extensibility via smart contract
applications
▶ User Tasks: human / organizational performer
▶ Proxy contract permissioning
▶ On-chain script (smart contract): synchronous processing
▶ Read
▶ Write
▶ Read+Write
▶ Off-chain integration (smart contract): asynchronous processing
▶ Read
▶ Write
▶ Read+Write

12. Branching allows extensible,
sophisticated processes

13. Loops and conditionals without IFs or
FORs

14. Getting Started
▶ Install burrow (see https://github.com/hyperledger/burrow)
▶ Clone blackstone
(https://github.com/agreements-network/blackstone)
▶ Deploy contracts (./contracts/deploy_contracts)
▶ Start API (cd api && npm start)
