Learn about blockchain development Note 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 Hyperledger Sawtooth is another general-purpose blockchain framework under Hyperledger Umbrella for building both distributed ledgers: Compared to Fabric, Sawtooth is more similar to a public blockchain such as Ethereum, but still maintains some design principles.

Hyperledger enforces modularization, configurability, and flexibility in plugging in different implementations. It maintains a cryptographically linked chain of transaction blocks, has a peer-to- peer validator network for relaying transactions between nodes, and relies on the gossip protocol to propagate all transactions to all nodes in the validator network.

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: At the network level, its task is to configure who has permission to join the validator network. At the local validator configuration level, it controls whether the validator has permission to access and process the transactions and messages.

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. A permissioned blockchain, initially contributed by IBM and Digital Asset, Fabric is designed to be a foundation for developing applications or solutions with a modular architecture.

It takes plugin components for providing functionalities such as consensus and membership services. Like Ethereum, Hyperledger Fabric can host and execute smart contracts, which are named chaincode. A Fabric network consists of peer nodes, which execute smart contracts chaincode , query ledger data, validate transactions, and interact with applications.

User-entered transactions are channeled to an ordering service component, which initially serves to be a consensus mechanism for Hyperledger Fabric. Special nodes called Orderer nodes validate the transactions, ensure the consistency of the blockchain, and send the validated transactions to the peers of the network as well as to membership service provider MSP services. Two major highlights of Hyperledger Fabric versus Ethereum are: Multi-ledger: Each node on Ethereum has a replica of a single ledger in the network.

However, Fabric nodes can carry multiple ledgers on each node, which is a great feature for enterprise applications. Private Data: In addition to a private channel feature, unlike with Ethereum, Fabric members within a consortium can exchange private data among themselves without disseminating them through Fabric channel, which is very useful for enterprise applications. Here is a good article for reviewing all Hyperledger Fabric components like peer, channel and, chaincode that are essential for building blockchain applications.

In short, thorough understanding of all Hyperledger Fabric components is highly recommended for building, deploying and managing enterprise-level Hyperledger Fabric applications. It can be run on the Ethereum public network or on private permissioned networks, as well as test networks such as Rinkeby, Ropsten, and Gorli. Hyperledger Besu supports several consensus algorithms including PoW, PoA, and IBFT, and has comprehensive permissioning schemes designed specifically for uses in a consortium environment.

The EEA specification was established to create common interfaces amongst the various open and closed source projects within Ethereum, to ensure users do not have vendor lock-in, and to create standard interfaces for teams building applications.

Besu implements enterprise features in alignment with the EEA client specification. As a basic Ethereum Client, Besu has the following features: It connects to the blockchain network to synchronize blockchain transaction data or emit events to the network. It uses a data storage of networks blocks. It publishes client API interfaces for developers to interact with the blockchain network. Clique is a proof-of-authority blockchain consensus protocol. The blockchain runs Clique protocol maintaining the list of authorized signers.

These approved signers directly mine and seal all blocks without mining. Therefore, the transaction task is computationally light. When creating a block, a miner collects and executes transactions, updates the network state with the calculated hash of the block and signs the block using his private key.

By using a defined period of time to create a block, Clique can limit the number of processed transactions. IBFT 2. Transactions and blocks in the network are validated by authorized accounts, known as validators. Validators collect, validate and execute transactions and create the next block. Existing validators can propose and vote to add or remove validators and maintain a dynamic validator set. The consensus can ensure immediate finality.

As the name suggests, IBFT 2. In IBFT 2. It also has JavaScript and Golang components. Sawtooth supports both permissioned and permissionless deployments. By design, Hyperledger Sawtooth is created to address issues of performance. As such, one of its distinct features compared to other Hyperledger DLTs is that each node in Sawtooth can act as an orderer by validating and approving a transaction.

Other notable features are: Parallel Transaction Execution: While many blockchains use serial transaction execution to ensure consistent ordering at every node on the network, Sawtooth follows an advanced parallel scheduler that classifies transactions into parallel flows that eventually leads to the boost in transaction processing performance.

Behlendorf told CoinDesk: "[Hyperledger] isn't just a collection of farm animals in one big barn. There really is a point to bringing these communities together and having them work out organically how they might sit on top of one another and be components into a broader architectural vision. Key collaborations Elsewhere, there's other evidence to suggest Sawtooth Ethereum is proof that Hyperledger is growing organically in the way Behlendorf described.

Because of this integration, ethereum developers with existing smart contracts are expected to be able to "transition their work to the Hyperledger Sawtooth platform" eventually, according to the blog post on the launch. Monax co-founder, Casey Kuhlman, said in the post: "Hyperledger Burrow has long been positioned to provide a core EVM that would then be utilized by other Hyperledger projects. Once the transaction processor validates the business rules, the Validator then adds the block to the Blockchain and transmits the message of the successful transaction across all the nodes.

According to Sawtooth documentation , in Hyperledger Sawtooth, the application environment and the core ledger system are completely separated from each other. An ideal architecture for any system, this also allows the platform to be highly scalable to handle extreme data load.

This particularly is very effective while dealing with systems containing complex transactions. The Seth transaction processor along with the help of the Hyperledger Burrow Ethereum Virtual Machine, enables the execution of Ethereum smart contracts on the Sawtooth platform. Hyperledger Sawtooth allows Parallel Transaction Execution due to its ability to group transactions into batches. In situations of multiple related transactions, Sawtooth configures special transaction processors that process concurrent transactions.

You can also configure transactions in different permutations and combinations but only after ensuring that they comply with the Atomicity, Consistency, Isolation and Durability ACID principle. Hyperledger Sawtooth - Conclusion From what we read above, Hyperledger Sawtooth has all the features and characteristics that are required to build an enterprise grade modular application.

Sawtooth is the perfect choice when it comes to applications that demand high efficiency, scalability and complex transaction execution.
