1. What started the large interest in permissioned blockchain technologies such as Hyperledger?

Many businesses found that the core systems of blockchain tech could solve a number of their problems. However, they were still facing underlying issues on scalability and the drawbacks of control in a permission less blockchain. That’s where Hyperledger came in.

2. Why are the popular public blockchains not suitable for business use cases?

Usually, companies want to keep their proprietary information classified, and only accessible to approved parties. That’s why they require a permissioned blockchain system rather than a permissionless one.

3. What programming languages can be used to write smart contracts on Hyperledger Fabric?

Jave, Node.js and Go.

4. What does it mean to have support for “pluggable consensus protocols”?

It means the program can be easily customizable to fit certain use cases.

  1. The popularity of Bitcoin and Ethereum led to interest in Hyperledger being developed. Hyperledger was designed for enterprise use, whereas permissionless blockchain technologies were not.
  2. Lack of confidentiality, businesses wouldn’t want their transactions made public
    participants must be identified, networks need to be permissioned, high transaction throughput performance and low latency of transaction confirmations.
  3. Java, Go and Node.js
  4. Enables the platform to be more effectively customized to fit particular use cases and trust models. Enterprises can choose between crash fault-tolerant (CFT) consensus protocol or byzantine fault tolerant (BFT) consensus protocol - whichever one suits that platforms needs.

  1. What started the large interest in permissioned blockchain technologies such as Hyperledger?
    Started when the nature of permissioned blockchain solved many of the issues that organizations have with permissionless blockchain.
    Like:
  • Participants must be identified/identifiable
  • Networks need to be permissioned

  1. Why are the popular public blockchains not suitable for business use cases?
    Because participants are not identified, anyone can contribute , lack of privacy and also there is a performance aspect as well.

  2. What programming languages can be used to write smart contracts on Hyperledger Fabric?
    Currently Go and Node.js but looking to implement Java and many more

  3. What does it mean to have support for “pluggable consensus protocols”?
    In Fabric , consensus is a logically decoupled from peers that execute transactions and maintain the ledger. Having this modularity gives the option of tailoring the implementation to fit the needs of different stakeholders.

1. What started the large interest in permissioned blockchain technologies such as Hyperledger?
Enterprises, versus individuals, are more focused on being able to identify the participants in the network (versus privacy / anonymity), being able to authorize who can and can’t enter the network (since it’s private company ‘property’), ensuring fast and efficient transaction processing (for better profitability), and confidentiality of some or all transactions to protect company IP and other proprietary data

2. Why are the popular public blockchains not suitable for business use cases?
The popular public blockchains are open to anyone, anywhere (permissionless). In addition, transaction execution and confirmation can take a longer time. Lastly, governance and transparency are ‘public’ and not able to be controlled by a central entity

3. What programming languages can be used to write smart contracts on Hyperledger Fabric?
Java, Go and Node.js as examples

4. What does it mean to have support for “pluggable consensus protocols”?
It means that there is a modular component for consensus of transactions that is separate and independent from the peers that execute the transactions and maintain the ledger

1)The main interest in the permissioned blockchain technology was in the need of a KYC and to trace the identity and the authority to joining the network. Many business was interested in the blockchain technology but the permisionless network weren’t able to deliver the business needs.

2)because you reveal business operations to the public, networks are permisionless, there are slower transactions and confirmation, and open governance.

3)Java, Go, node.js

4)Enables the platform to be more effectively customized to fit particular use cases and trust models

1. What started the large interest in permissioned blockchain technologies such as Hyperledger?
The popularity of successful blockchain use-cases such as Bitcoin and Ethereum, which allowed to understand how useful may be the usage of this technology in a enterprise environment.
2. Why are the popular public blockchains not suitable for business use cases?
Because of performance issues, such as having a higher transaction throughput, with lower transaction confirmation lag, at a much lower cost. They also need to fulfill compliance requirements (such as KYC and AML), related to data privacy and confidentiality, protection of key secret data of the company, and the ability to identify every participant in the network. This implies a permissioned network, when all users are identified (so it isn’t anonymous), and have different degrees of access to the data.
3. What programming languages can be used to write smart contracts on Hyperledger Fabric?
Java, Node JS and Go
4. What does it mean to have support for “pluggable consensus protocols”?
It means that you can choose the most suitable consensus protocol for your use case. For instance, you may use crash fault-tolerance (CFT) consensus protocol in a more centralized company or consortium, or you can use a byzantine fault-tolerant (BFT) protocol in a more distrubuted environment.

  1. What started the large interest in permissioned blockchain technologies such as Hyperledger?
    The need for Enterprise / business use applications amid the KYC & AML regulations.

  2. Why are the popular public blockchains not suitable for business use cases?
    There is mining, anonymous participants & tax code compliance complications, nodes are peer / trusted nodes, quicker transactions speeds due to lessened consensus model due to less decentralization,

  3. What programming languages can be used to write smart contracts on Hyperledger Fabric?
    Java, Go and Node.JS.

1. What started the large interest in permissioned blockchain technologies such as Hyperledger?
A: The fact that, while quite interested in the blockchain technology, they require performance that the permissionless blockchain technologies are unable (as of today) to deliver. Additionally, in many use cases, the identity of the participants is a must, as in the case of financial transactions where Know-Your-Customer (KYC) and Anti-Money Laundering (AML) regulations must be followed.

2. Why are the popular public blockchains not suitable for business use cases?
A: Because business has requirements that are not adequately addressed by public blockchains, such as:

  • Participants must be identified/identifiable
  • Networks need to be permissioned
  • High transaction throughput performance (TPS)
  • Low latency of transaction confirmation
  • Privacy and confidentiality of business transactions

3. What programming languages can be used to write smart contracts on Hyperledger Fabric?
A: General-purpose programming languages such as Java, Go and Node.js, rather than constrained domain-specific languages (DSL).

4. What does it mean to have support for “pluggable consensus protocols”?
A: It means that enable the platform can be customized to fit particular use cases and trust models.

  1. What started the large interest in permissioned blockchain technologies such as Hyperledger?

The what started the large interest in permission blockchain technologies such as Hyperledger as to allow enterprise use cases that require performance characteristics that the permissionless blockchain technologies are unable (presently) to deliver. This knowing the identity of the participants is a hard requirement, such as in the case of financial transactions where Know-Your-Customer (KYC) and Anti-Money Laundering (AML) regulations must be followed.

  1. Why are the popular public blockchains not suitable for business use cases?

Popular blockchains are not suitable for some business use cases due to data is transparent - there is no privacy or confidentiality of data or transactions. Networks are permissionless. Slower transaction performance and confirmation. Open governance

  1. What programming languages can be used to write smart contracts on Hyperledger Fabric?

Programming languages used to write smart contraction Hyperledger Fabric are Java, Go and Node.js which are general purpose programming languages

  1. What does it mean to have support for “pluggable consensus protocols”?

Pluggable consensus protocols mean since consensus is modular, its implementation can be tailored to the trust assumption of a particular deployment or solution. This modular architecture allows the platform to rely on well-established toolkits for CFT (crash fault-tolerant) or BFT (byzantine fault-tolerant) ordering.
