The Sawtooth Lake is a blockchain project proposed by Intel in April 2016 with some key innovations focusing on the decoupling of ledgers from transactions, flexible usage across multiple business areas using transaction families, and pluggable consensus.
Decoupling can be explained more precisely by saying that the transactions are decoupled from the consensus layer by making use of a new concept called transaction families.
Modular Blockchain for Enterprise Applications
Instead of transactions being individually coupled with the ledger, transaction families are used, which allows for more flexibility, rich semantics, and open design of business logic.
Transactions follow the patterns and structures defined in the transaction families.
Some of the innovative elements Intel has introduced include a novel consensus algorithm abbreviated as PoET, Proof of Elapsed Time, which makes use of Trusted Execution Environment (TEE) provided by Intel Software Guard Extensions (Intel’s SGX) to provide a safe and random leader election process.
