Blockchain in the Browser

Blockchain is a distributed ledger that records transactions in a secure, flexible, verifiable and permanent way. The talk focuses on how Blockchains can be interacted with or modified from the Browser. Examples were focused on Hyperledger Blockchains and tools.

3. What is Blockchain ... a distributed ledger that records transactions in a secure, flexible, verifiable and permanent way* Uchibeke and others in IEEE Cybernetics 2018 (http://cse.stfx.ca/~cybermatics/2018/Proceedings/pdfs/iThings!GreenCom!CPSCom!SmartData!Blockchain!CIT!Cybermatics2018-1Q1rrimpxFNyCxx89cHrQN/7ulNQ4fpJr6beQEQNaBxjG/255il6J1usQ8tk371S50r U.pdf)
4. Keywords: distributed ledger • By design, gives us multiple nodes for free • No single point of failure • Protects from the WanaCry
5. Keywords: transactions • Day to day operational tasks that we already do ◦ Exchange of asset ◦ Execution of the clause of an agreement ◦ Update to customers/merchants Identity information
6. Keywords: secure, flexible, verifiable & permanent • A hacker would have to hack each and every node on the blockchain at exactly the same time to be successful. ◦ Statistically, highly unlikely
7. Low Level High Barrier of entry High Investment Web Browser Low Barrier of entry Quick POC to browser
8. Hyperledger Blockchain
9. Tools: Hyperledger Fabric • Private and permissioned blockchain • Linux Foundation Project • Provides benefit of blockchain without sacrificing speed or scalability https://www.hyperledger.org/projects/fabric
10. Tools: Hyperledger Composer • Modeling tool • Rapid prototyping of blockchain POC https://www.hyperledger.org/projects/composer
11. Tools: Hyperledger Playground • Interact with Hyperledger Blockchain from browser • Requires soe tech knowledge (JSON, REST etc) https://composer-playground.mybluemix.net/editor
12. Tools: Hyperledger composer form generator? • Generates a form from a Composer model file • Fill out form and click button to submit • Working on this https://github.com/uchibeke/composer-form
