Learn about blockchain development
If you are new to the blockchain technology, taking our Introduction to Blockchain Technology self-paced course is highly recommended. Also, for a comprehensive coverage of blockchain development with Sawtooth, taking our below self paced courses is highly recommended:
Hyperledger Sawtooth is another general-purpose blockchain framework under Hyperledger Umbrella for building both distributed ledgers:
While Fabric is a permissioned blockchain, Sawtooth supports both permissioned and permissionless blockchains. Permissions are set at both the network level and the local validator configuration level:
Unlike other private blockchains such as Hyperledger Fabric, Corda, or Quorum, where a sensitive or private transaction may not be accessible to all nodes, all transactions in Sawtooth are stored in validators in the network; it relies on the local permissions to enforce transaction privacy.
The consensus in Sawtooth, by design, is pluggable too. Consensus algorithms can be configured at the network level during the initial validator network's setup. They can be switched during the transaction process too. By default, it supports the Proof of Elapsed Time (PoEt) consensus protocol, although a voting-based consensus in RAFT is under development. PoET is a Nakamoto-style lottery-based consensus algorithm that relies on Intel's Software Guard Extensions (SGX) to select a validator to create blocks based on random waiting times, without using the PoW algorithm.
Similar to Fabric, Sawtooth supports smart contract development in many different programming languages, such as Java, JavaScript, Go, and on. In addition, it supports Solidity and Rust too, which are quite successful in the Ethereum community. One notable difference with transaction processing in Sawtooth is the ability to batch the transactions and ensure all or nothing when processing all the transactions in a batch. This could be quite useful for an enterprise that's dealing with some business scenarios with large, complex transactions.
