What is Hyperledger Fabric
Hyperledger Fabric is a private blockchain for the development of decentralized solutions. It has a modular architecture that offers a high degree of privacy, flexibility, resilience and scalability. This allows you to use fabric to develop solutions that are suitable for any industry.
How does Hyperledger Fabric work?
The Fabric Framework allows you to use components such as consensus and membership services via plug-and-play.
What does that mean exactly?
Hyperledger Fabric uses container technology to host Smart Contracts (also called chain code in the Hyperledger Framework). These chain codes define the business processes and rules of the system. This means that you can set up contracts between companies in chain code. They will be executed fully automatically when the specified contractual requirements have been met by both parties. It is also designed to support different plug-in components.
Thus, hyperledger fabric does not offer “one-size-fits-all” solutions. Instead, it is a modular blockchain platform for the execution of decentralized applications. In addition, you can use different consensus methods. As a result, fabric fits for a lot of use cases.
Benefits of Hyperledger Fabric
Fabric offers the possibility to run dapps in different programming languages. Therefore, you don´t need a specific cryptocurrency. In contrast, other blockchain platforms usually require a domain-specific programming language or a specific cryptocurrency.
In addition, Hyperledger Fabric is a private blockchain that enables industry-standard identity management. So, to support this flexibility, fabric developed a novel architectural approach. This, they redesigned the way blockchains handle resource and hack attacks.
Fabric also enables the creation of channels. This allows a group of users to create a separate ledger with transactions. This is important when network partners are competitors and they need to hide information. Such an example could be a special price that only certain partners should see. This means that if a group of users creates a channel, only they will have a copy of the ledger.
What is Hyperledger Burrow?
Hyperledger Burrow is a private smart contract platform. It is a modular blockchain client with a smart contrat interpreter, which is partly based on the Ethereum Virtual Machine (EVM).
Thus, Burrow is a smart contract oriented blockchain. So it is protected by an access control layer through the use of Smart Contracts and an authorization layer.
How does Hyperledger Burrow work?
Burrow has a consensus engine that manages the nodes and orders transactions. So it has a smart contract application engine that enables developers to perform complex industrial processes.
If you want to connect the consensus engine and the smart contract application engine, you need an application blockchain interface. This provides a blockchain-specific interface so that you can connect two engines smoothly. Finally, a gateway is used, which provides an interface for system integration and user interfaces.
What is Hyperledger Indy?
Hyperledger Indy is a private blockchain that was developed especially for decentralized identities. Indy provides a variety of tools, libraries and reusable tools. Thus, you can create independent digital identities with it.
These identities can communicate across domains, applications, and other organizational systems. As a result, both business partners and competitors can rely on a common source of truth.
How does Hyperledger Indy work?
With Hyperledger Indy it is possible to find out who you are working with. It also helps you to find out information about the other party. Because the information is valid, you can handle business interactions with confidence.
For this purpose, the identity artifacts are stored on the blockchain. These artifacts can include private keys, proof of existence, withdrawal keys and many more. Only the true owner of the identity can change or remove something on the blockchain.
Indy preserves privacy, as there is no direct relationship to the user’s information and identity.
So you can confirm identities with your birth certificate, driver license or passport. You can use zero-knowledge proofs to confirm these identities without actually revealing the information about the user.
Benefits of Hyperledger Indy
Hyperledger Indy offers an enormous range of advantages in areas such as self-protection, privacy, and legal claims.
For example, you are able to delete large amounts of sensitive data. That is because everything is stored on one database and not distributed across many different databases. Also, only the owner of the data can access this information.
In addition, Indy meets the growing demands for privacy and regulatory compliance. Different companies can benefit from more secure interactions, which can create innovative new market dynamics.
Hyperleder Indy also offers a simple and easy to use API despite a very secure infrastructure. This makes it easy to use and benefit from Indy functionality in other systems.
What is Hyperledger Iroha?
Hyperledger Iroha is a blockchain framework that provides features to develop distributed applications for end-users. Iroha is designed to be easily and simply integrated into blockchain projects.
How does Hyperlayer Iroha work?
As mentioned before, Iroha has a simple structure that allows you to quickly and easily develop dapps. The reason for this is a modern domain-related C++ design. This ensures that Iroha is very useful for the development of mobile applications. The reason for that is a new Byzantine-oriented consensus algorithm. This helps to easily scale solutions.
What is Hyperledger Sawtooth?
Hyperledger Sawtooth is a modular blockchain platform for the development, deployment and operation of blockchain infrastructure. Decentralized ledgers provide a digital audit that you can manage without a central authority or implementation. So Sawtooth ensures that the blockchain remains decentralized. It also helps companies to use smart contracts safely and securely. In addition, Hyperledger Sawtooth is highly modular. This allows companies to decide on their own Dapps and not be affected by forks.
How does Hyperledger Sawtooth work?
Hyperledger Sawtooth uses a dynamic consensus. This means that companies can change the consensus algorithm of a blockchain simply by creating a transaction.
Basically Sawtooth uses a new and innovative consensus algorithm. This is called Proof of elapsed time (PoET).
What is Proof of elapsed time (PoET)?
Proof of elapsed time is nothing else than the Proof of Work consensus mechanism. The big advantage of PoET is that it has the scalability of Proof of Work, but it does not consumes a lot of power.
If you want to develop smart contracts on the Sawtooth blockchain, you can also develop them in any programming language. This also applies to different Smart Contract interpreters such as Hyperledger Burrow or EVM. You can also use Ethereum Smart Contracts in Sawtooth.
You can also process transactions way faster in Sawtooth thanks to a parallel scheduler. Therefore, a consistent sequence does not have to be maintained as with other blockchains. The faster block processing means that the scaling problem can be virtually solved. You can also send transactions privately with separate authorizations. This protects both trust and privacy.
