This video will demonstrate how an Ethereum Smart Contract can use Bluzelle Database.
Text guide: https://blog.bluzelle.com/ethereum-smart-contract-support-in-bluzelles-lovelace-release-f8ff22a2b906
We assume:
– The viewer of this video is adept with Ethereum and writing Solidity Smart Contracts
– Metamask (or the equivalent) is configured as needed, and is holding sufficient ETH from the Ropsten network to test with
– The viewer already has installed the Bluzelle desktop CRUD application (Detail guide to setup: https://github.com/bluzelle/crud)
The tutorial will go through the following steps:
Part I: Smart Contract Deployment
1. Copy the sample smart contract code to Ethereum Remix (link to sample code: https://github.com/bluzelle/bluzelle-sol/blob/master/contracts/SampleDappPublic.sol)
2. Compiling and deploying the smart contract to the Ropsten testnet using Ropsten ETH
3. Retrieving the ABI and smart contract address for later use
Part II: Using Smart Contract
1. Setting up MyEtherWallet with deployed smart contract values (found during deployment)
2. Executing a CREATE operation (onchain), from MyEtherWallet
3. Verifying the CREATE complete (offchain) with a READ, via the desktop CRUD application
4. Changing the key-value-pair value (offchain) with an UPDATE, via the desktop CRUD application
5. Reading the changed value back (onchain), from MyEtherWallet
* You can modify the sample smart contract based on your needs
