Hyperledger Composer simplifies application development on top of the Hyperledger Fabric blockchain infrastructure. If you are interested in the blockchain infrastructure, start with the Fabric tutorials. If you are interested in blockchain applications, start with the Composer tutorials. The Fabric tutorials also include samples of low level chaincode development (in golang). Composer is a higher … Read more
Here are the important differences to consider when choosing between Hyperledger Fabric and Hyperledger Sawtooth: Permissioned/Permissionless Hyperledger Sawtooth supports both permissioned and permissionless blockchain networks. Sawtooth has a flexible approach using roles and permissions. Hyperledger Fabric supports only permissioned blockchain networks. Fabric has a prescriptive/well-defined approach through pluggable membership service providers (MSPs) that enables a … Read more
