Types of blockchain networks
Blockchain networks can be categorized into public, private, or hybrid, depending on who can access and participate in them.
- Public blockchains: Public blockchains are open and permissionless, meaning anyone can join and contribute to the network. They are usually decentralized and democratic, meaning no one has control or authority over the network. Examples of public blockchains are Bitcoin and Ethereum.
- Private blockchains: Private blockchains are closed and permissioned, meaning only authorized entities can join and contribute to the network. They are usually centralized and hierarchical, meaning someone has control or authority over the network. Examples of private blockchains are Hyperledger Fabric and Corda.
- Hybrid blockchains: Hybrid blockchains are a combination of public and private blockchains, meaning they have some features of both. They are usually designed to achieve a balance between security, transparency, scalability, and interoperability. Examples of hybrid blockchains are Quorum and Dragonchain.
Types of consensus mechanisms
Consensus mechanisms are the rules and processes that govern how transactions or data entries are validated and added to the ledger. They are essential for ensuring the integrity and reliability of the ledger. There are many types of consensus mechanisms, but some of the most common ones are:
- Proof-of-work (PoW): PoW is a consensus mechanism that requires participants to solve complex mathematical puzzles to verify transactions or data entries. The first participant to solve the puzzle gets to add the block to the ledger and receive a reward. PoW is used by Bitcoin and Ethereum.
- Proof-of-stake (PoS): PoS is a consensus mechanism that requires participants to stake or lock up a certain amount of tokens or coins to verify transactions or data entries. The participants with the highest stake have a higher chance of adding the block to the ledger and receiving a reward. PoS is used by Cardano and Polkadot.
- Proof-of-authority (PoA): PoA is a consensus mechanism that requires participants to have a certain reputation or authority to verify transactions or data entries. The participants with the highest reputation have a higher chance of adding the block to the ledger and receiving a reward. PoA is used by VeChain and POA Network.
- Byzantine fault tolerance (BFT): BFT is a consensus mechanism that requires participants to reach an agreement on transactions or data entries through a voting process. The participants need to have at least two-thirds of the votes to add the block to the ledger and receive a reward. BFT is used by NEO and Stellar.
Types of blockchain platforms
Blockchain platforms are software frameworks that allow developers to create and deploy blockchain applications or solutions. They provide various tools and features that simplify the development process and enhance the functionality of the applications or solutions.
