What's the difference between Hyperledger Fabric and Sawtooth?

Question

Both Hyperledger Fabric and Hyperledger Sawtooth are platforms for building distributed ledger applications, supporting pluggable consensus mechanisms and smart contracts (chaincodes).

What are the main differences between then? When to choose one over the other to implement a blockchain solution?

Answer 1

The differences between Hyperledger Fabric and Hyperledger Sawtooth are many. They can be listed down as:  

Feature/Protocol	Hyperledger Fabric	Hyperledger Sawtooth
Blockchain Type Support	Supports only permissioned blockchain networks as it features MSPs for enabling secure governance.	Supports both permissioned and permission-less blockchain networks as it enables flexible roles and permissions
Consensus Algorithm	Supports pluggable consensus algorithms.	Supports Proof of Elapsed Time (PoET) which is more energy-efficient and effective than traditional Proof of Work.
Smart Contract Language	Supports Go, JavaScript, Java, Python, Rust, and Solidity based Smart Contracts.	Supports Go, Java, JavaScript, and Solidity based Smart Contracts.
Privacy	Enables multiple levels of privacy and channels can be defined to preserve anonymity and stronghold security as per requirements.	Users can have access to all transaction data.
Transaction Flow	Transactions are executed at an initial level on a set of users by following an Execute-Order-Commit Model. Therefore, scalability and security in transactions are substantially improved.	Supports the traditional blockchain flow ‘Order-Execute-Commit’
General Differences	Supports queries from smart contracts using the key range or JSON queries.	Either all transactions are committed or none of them are committed.
