Service: Amazon Managed Blockchain
Answer:
Amazon Managed Blockchain supports smart contracts and chaincode using two open source blockchain frameworks: Ethereum and Hyperledger Fabric.
For Ethereum, developers can write smart contracts in Solidity or Vyper, which are the two main programming languages for Ethereum smart contracts. These smart contracts are deployed to the Ethereum Virtual Machine (EVM) and executed on the nodes in the Ethereum network.
For Hyperledger Fabric, developers can write chaincode in various programming languages such as Go, JavaScript, and Java. The chaincode is deployed to the peers in the network and executed within a Docker container.
To develop and manage smart contracts and chaincode, Amazon Managed Blockchain integrates with various AWS services such as AWS Lambda, AWS CloudFormation, and Amazon S3. Developers can use AWS Lambda to execute code in response to events on the blockchain, while AWS CloudFormation provides a way to automate the deployment of blockchain networks and resources. Amazon S3 can be used to store and manage data associated with the blockchain network.
Amazon Managed Blockchain also provides a web-based console and APIs that allow developers to create and manage smart contracts and chaincode, monitor network activity, and manage network resources.
