Learn how to set up a blockchain network and deploy your first application using Amazon Managed Blockchain. Attendees will build a blockchain network for a nonprofit organization, to allow the nonprofit to distribute funds without an intermediary. This will ensure immutable transactions and full transparency to a donor about how his/her donation is being used. Using Hyperledger Fabric on Amazon Managed Blockchain, workshop attendees will create a peer node and connect the node to the nonprofit blockchain network. In the example application, donors can register their profiles with the nonprofit network, review the nonprofit and the causes it supports, and donate funds. Using smart contracts, the nonprofit will distribute the funds and the network will track how each donor's donation is allocated. In addition to donors viewing how their contributions have been spent, donors can view all donations received by the nonprofit and how they've been spent.

WorkshopObjectives The objective of this workshop is to create an AWS Managed Blockchain Fabric network, then deploy an application that interacts with the Fabric network. You will do the following: • Create an AWS Managed Blockchain Fabric network • Create a peer node in the network • Create a new channel, install and instantiate chaincode • Query the chaincode and invoke transactions • Deploy a RESTful API which connects to the Fabric network and exposes the chaincode functions as REST endpoints • Test the RESTful API using cURL • Deploy a Node.js application that calls the RESTful API

Getting started Look at the README here: https://tinyurl.com/y7h6369b Start with Part 1 Use the AWS Console to create a Fabric network Create a AWS Cloud9 instance Use AWS Cloud9 to create a Fabric client node From the Fabric client node, install chaincode, test chaincode, etc. On the Fabric client node install the RESTful API On the AWS Cloud9 instance, install the Node.js application

- RDBMS All statements that mutate or change data are written to a transaction log (i.e. the binary log in MySQL). Updates to the log are cached until the transaction is committed, at which point they are written to the transaction log. Databases can be rolled backwards and forwards using the events in the transaction log. Useful for point in time recovery. These logs are often used for replication, where the events are send to replicas who play the events in order. I still have a central copy of my master database, and I potentially have read replicas and slave databases Ethereum Uses an order-execute model My $100 transaction, along with other transactions happening right now, are sent to miners Transactions are sent to miners who group them into blocks and propose the next block in the chain The first miner to complete the PoW on a block with the required difficulty level, broadcasts the block to all other nodes on the network Each peer node receives the same blocks Each peer nodes loops through the transactions in the block and executes the smart contract (i.e. the Solidity code) against this transaction. The results of the smart contract are then applied to the World State, which is just a KV store, and the block is stored in the blockchain. The new block is cryptographically signed, and linked to the previous block See the parallels to an RDBMS? The results are similar in that we end up with a world state and an event store (i.e. a blockchain), but the process is different because we have to apply the change to thousands of nodes globally, rather than to just one node (in the case of an RDBMS). Hyperledger Uses execute-order-validate Each endorsing peer simulates the TX first, but does not update the blockchain or the world state. Then the TX is sent to the orderer where it is grouped into a block The block is then sent to all peer nodes Each peer node validates the block and stores the block in the blockchain The transactions in each block are processed and applied to the World State, which is just a KV store
