Which Are the Most Popular Blockchain Networks?

Layer two networks have emerged which are less decentralised than public blockchain vs private blockchain their layer one equivalents, but they can support a greater transaction throughput. Examples include the Polygon network for Ethereum and the Lightening network for Bitcoin. There are four main types of Blockchain networks- Public, Private, Hybrid, and Consortium. And here, the question arises why we need these different Blockchain types or networks. These skyrocketing market statistics have led industries toward this platform for making highly secured transactions and providing their customers with a safe & amazing experience. These blockchains are completely open to following the idea of decentralization.

There are four main kinds of the technology used in the crypto, NFT and Web3 sectors.

All the nodes within the blockchain have equal rights to access and interact with the network. This kind of blockchain is often used for exchanging and mining cryptocurrency. The most widespread consensus mechanisms https://www.xcritical.com/ used in public blockchains are proof-of-work and proof-of-stake. In general, there are private and public blockchains, while hybrid blockchains try to combine different aspects of private and public blockchains for specific use cases.

Why permissioned blockchains are ideal for business applications

For example, “permissioned” can encompass private, consortium and, in some contexts, hybrid blockchains—but is not directly interchangeable with any of those terms. Similarly, “permissionless” is a broad term that’s often applied to, but not synonymous with, public blockchains. Classification ultimately depends on the specific blockchain’s design and implementation. This is one of the biggest disadvantages of private blockchain and goes against the core philosophy of distributed ledger technology or blockchain in general. A private blockchain is one of the different types of blockchain technology. A private blockchain can be best defined as the blockchain that works in a restrictive environment, i.e., a closed network.

How Many Blockchain Networks Are There?

Consequently, consensus on private blockchains is achieved much faster, and the risk of overload is low, unlike public blockchains. A consortium blockchain tends to be more secure, scalable and efficient than a public blockchain network. Consortium blockchains are a specific type of permissioned blockchain in which a group of organizations share control and governance of the network. Compared to a single-entity, private blockchain, these models foster increased trust and security.

Where Can We Use Different Types of Blockchain Networks?

All types of blockchains can be characterized as permissionless, permissioned, or both. Permissionless blockchains allow any user to pseudo-anonymously join the blockchain network (that is, to become “nodes” of the network) and do not restrict the rights of the nodes on the blockchain network. A hybrid blockchain is a type of blockchain that combines elements of both public and private blockchain. It allows for a mix of open and restricted access to the network, depending on the use case and application. In contrast to a public blockchain, a private blockchain is a closed database that uses cryptography to ensure security and comply with the organization’s requirements. Many enterprises use this option to keep some or all of their transactions private or only for internal uses.

Decentralized Identifiers (DIDs) for Digital Identity Management

A number of companies are active in this space providing services for compliant tokenization, private STOs, and public STOs. Most cryptocurrencies use blockchain technology to record transactions. For example, the bitcoin network and Ethereum network are both based on blockchain.

Why Some Organizations Use Private Blockchains

This means that some of the partners have rights as to a private blockchain, and the others have rights as to a public blockchain. Private blockchains are rather so called because they are data registers, access to which requires authorization. These permissions are granted by administrators, and help to guarantee the security of the information, since the prerogatives of the public regarding reading or adding data are limited.

Such Blockchain is mostly used within an organization where only particular members are participants of a Blockchain network. It is best suited for enterprises and businesses that want to use Blockchain only for internal uses. The major difference between the Blockchains is that the public is highly accessible, whereas private is confined to a particular group of people. Moreover, a private Blockchain is more centralized due to the fact that a single authority maintains the network. IBM, R3 Corda, Hyperledger Fabric, Hyperledger Sawtooth, etc. are the examples of private Blockchains.

Some users may have malicious intentions and take advantage of anonymity, so the protocol must include certain counter-mechanisms. Blockchain technology ensures the reliability and immutability of data. Distributed ledger frees us from intermediaries; there’s no need for auditors. To learn more about blockchain, its underlying technology, and use cases, here are some important definitions.

In simple words, it is the best of both private and public blockchains. This blockchain type gives choices for access management and rights while controlling the same blockchain technology and earning its paybacks (Al-Jaroodi and Mohamed, 2019). Consortium blockchains are the union of a public and private blockchain that is partly decentralized. There are some controlling nodes to verify and validate transactions or blocks. The miner blocks are valid only when approved and signed by these controlling nodes. The data or transaction details can be open source, like public blockchains, but the nodes can verify and validate transactions instead of a specific individual or a single company.

By design, some might use immutability techniques such as cryptographic security measures and validation through consensus mechanisms. Public-permissioned blockchain networks also run on the internet, however, access to those networks is restricted. Only specific participants on the network can run transaction-validating nodes that can process transactions. In addition access to those nodes can be restricted either physically or by using a cryptocurrency created exclusively for this network.

A great example of this is Project Ubin, a collaborative Ethereum project that Consensys participated in with the Monetary Authority of Singapore to create an interbank payment network. While still an emerging business model, theyhave already found a wide variety of applications. Permissioned blockchains have been used to manage supplychains, create contracts, handle claims, verify payment between parties, and administer user identity. To date, public blockchains are primarily used for exchanging and mining cryptocurrency. You may have heard of popular public blockchains such as Bitcoin, Ethereum, and Litecoin.

• Bitcoin is much more suitable for law-abiding and regulated transactions, which – if necessary – can also be arbitrated by authorities.
• This can lead to slow transaction times and high fees during times of high network traffic.
• However, due to the level of decentralisation and security they provide, they do face scalability issues with the number of transactions they can process during a given time window.
• The main allure of private blockchain networks is that they’re effective for securing information.
• Public blockchains use consensus mechanisms such as Proof of Stake (PoS) or Proof of Work (PoW).

A smart contract defines conditions for corporate bond transfers, include terms for travel insurance to be paid and much more. Blockchain technology offers lots of opportunities for businesses across different sectors. It has been here for years, but it seems only now companies understand its value for their processes. It isn’t hard to predict that blockchain will impact the future as we know it, while 80% of banking experts say that blockchain will bring many changes in the next 20 years.
