This document discusses the author's approach to blockchain strategy and application development. The author works with clients who have issues with business processes and data sharing across organizations. The author believes blockchain can help with shared governance, processes, auditing, and reputation. Specifically, the author focuses on designing proofs of concept for clients over 2-3 month periods to test how blockchain could address their issues while conserving data privacy and ownership. The author develops applications using the Eris platform and smart contract language.

• my clients have issues with process
chains
• interfacing is hard and done wrong IMO
• governance issues
• liability issues
• technical issues
• enter blockchain - my key points
• shared governance
• shared processes
• audit trail
• member reputation

5. E C O - A P P S
• my clients are increasingly
domain connected
• value is in the data layer
• but …
• data is copied throughout
process chains
• version issues
• privacy and governance
• we need an approach…
• …conserving client properties

• i don’t care, clients do
• stakeholder governance
• data privacy
• performance
• trust or KYS is good for
liability and audits
• control what’s going on for
our chain

• design sprint | 1 week
• what process chain issue is my client having?
• where can blockchain add value?
• proof of concept | 2 months
• prototype based on design sprint
• test with few stakeholders
• pilot | 3-6 months
• evaluate concept - design/develop MVP
• all stakeholders participate

• develop - full account; test /w local validator - root
account; production /w cloud validators
• node/express middleware
• reduced to pure API server talking to contracts
• wrapping eris-contracts.js
• elm front-end
• talking to node API server
• material design

• keep it simple - attack vectors around
• fan of the factory/manager pattern - owner based
• using contracts as classes - familiar to me
• need to figure out key management - this is hard!
• permissions and modifiers keep things clear and secure
• bypass Solidity constraints using address[]
• maybe this is all wrong … newbie alert!

• great explainers and tutorials - I finally got Solidity
• easy to set up - docker containers
• love the EPM functions - compile, test, deploy
• even I can explain what’s going on..
• help on slack by Monax people - very helpful and
patient - but other community experts as well
