Sawtooth by Intel is another distributed ledger project in Hyperledger. It’s focused on being a highly modular platform for building new distributed ledgers for companies.

Sawtooth does not operate with a cryptocurrency. It maintains the security of the platform by allowing businesses to create private blockchains. These businesses running private blockchains then share the burden of computational requirements with the network. In its documentation, Sawtooth states that this type of setup will ensure universal agreement on the state of the shared ledger.

Sawtooth has taken the basic model of blockchains and turned it on its head. Most blockchains have three elements:

 A shared record of the current state of the blockchain

 A way of inputting new data

 A way of agreeing on that data

Sawtooth merges the first two into a signal process it calls a transaction family. This model is best in use cases where all the participating parties have a mutual benefit to having a correct record.

Intel has allowed its software to be flexible enough to accommodate custom transaction families that reflect the unique requirements of each business. It also built three templates for building digital assets.

 EndPointRegistry: A place to record items in a blockchain

 IntegerKey: A shared ledger that is used for supply chain management

 MarketPlace: A blockchain trading platform for buying, selling, and trading digital assets
