Ripple is focused on facilitating cross-border payments. Each protocol adapts the basic blockchain principles to suit specific industries or applications.

Different Types Of Blockchain Protocols You Need To Know

1. Public Protocols

Public blockchain protocols are decentralized systems that allow for secure and transparent transactions without the need for intermediaries which is basically open-source. These protocols are open to anyone who wants to participate, and they provide a high degree of security through encryption and consensus mechanisms. 

In a public blockchain, miners and nodes work together to validate transactions and add them to the blockchain ledger. Blockchain Miners are responsible for solving complex mathematical problems to validate transactions and create new blocks, while nodes maintain a copy of the blockchain and validate transactions. 

The consensus mechanism, such as Proof of Work or Proof of Stake, ensures that all nodes agree on the state of the blockchain. Bitcoin, Ethereum, and Litecoin are some of the most popular public blockchain protocols. Bitcoin is primarily used as a store of value and for peer-to-peer transactions, while Ethereum is a platform for decentralized applications and smart contracts. Litecoin is a faster and more efficient version of Bitcoin, with lower transaction fees.

2. Private Protocols

Private blockchain protocols are designed for a specific group of participants, unlike public blockchain protocols that are open to anyone. Private protocols are characterized by their restricted access, permissioned nodes, and centralized governance. 

These protocols are commonly used by organizations that require a higher level of privacy and control over their data, such as financial institutions, supply chain management, and healthcare industries. Private blockchain protocols provide a secure and efficient way for these organizations to share data with each other while maintaining confidentiality and control over their data. 

Examples of popular private blockchain protocols include Hyperledger Fabric, Corda, and Quorum. These protocols offer features such as smart contracts, permissioned access, and privacy layers that make them ideal for enterprise-level applications.

3. Hybrid Protocols

Hybrid blockchain protocols are a combination of public and private blockchains that offer unique features and benefits. The purpose of hybrid protocols is to provide a solution that combines the security and transparency of public blockchains with the privacy and control of private blockchains.

FAQ

How is a blockchain protocol different from crypto?

A blockchain protocol is the foundational layer of code that sets up the framework for all activity on the blockchain. It determines the storage and transaction verification processes of digital assets. On the other hand, cryptocurrency is an encrypted string of data that has some monetary value. Cryptocurrency can be exchanged utilizing a blockchain protocol, but it is not restrained to it. For example, Bitcoin is a cryptocurrency that is exchanged utilizing the Bitcoin Protocol. Protocols can distinguish how digital assets are shared. In short, a blockchain protocol is the backbone of the blockchain platform, whereas cryptocurrency is the digital asset that is exchanged utilizing the blockchain protocol.

What is a node in a blockchain network?

A node in a blockchain network is a device that is connected to other devices through the internet. It plays a crucial role in verifying transactions and maintaining the distributed ledger. Every node in the network has equal importance and follows pre-defined rules, known as protocols, to interact with other nodes. Nodes can be set up by anyone with a computer, and they hold copies of the public ledger, similar to how banks hold records of financial transactions.

What is a ledger in a blockchain protocol?

In a blockchain protocol, a ledger is a record-keeping system that stores information about transactions on the network. The ledger is a distributed, decentralized database that is shared publicly across all the nodes in the network. Each block in the chain contains information about the transactions, and the blocks are linked together using a unique hash address. The ledger is maintained and updated by all the nodes in the network, and each node has an identical copy of the ledger.

How does a blockchain protocol ensure the security of data?

A blockchain protocol ensures the security of data through its decentralized and distributed ledger of transactions that is secured using cryptographic techniques. The key components of a blockchain protocol, such as the consensus algorithm, validation mechanism, network protocol, and data structure, work together to ensure that transactions are recorded and verified in a secure and reliable manner. Once a block is added to the blockchain, it becomes immutable, making it nearly impossible for any single node to modify it. For example, in Bitcoin, each node in the network works on pre-defined rules or protocols, and all nodes store an updated copy of the blockchain’s transaction records. If any node wants to change a record, the protocol mandates that it can only do so by also changing the records of all the nodes. This ensures the security and integrity of the data stored in the blockchain.

What are the 4 main components of blockchain?

A blockchain is a decentralized, distributed, and often public digital ledger that stores transactions across multiple computers. The four main components of a blockchain are the consensus algorithm, validation mechanism, network protocol, and data structure. These components work together to ensure that transactions are recorded and verified in a secure and reliable manner. The consensus algorithm ensures that all nodes in the network agree on the state of the ledger, the validation mechanism ensures that only valid transactions are added to the ledger, the network protocol defines how nodes communicate with each other, and the data structure organizes the transactions into blocks. This creates a secure and decentralized system where transactions can be verified and audited independently and inexpensively.

Does blockchain use TCP?

Blockchain protocols do not necessarily use TCP (Transmission Control Protocol) for data transmission. TCP is a network communication protocol that breaks data down into packets, addresses them, and routes them through the network to their final destination. Some blockchain protocols, such as Horizen and Bitcoin, use their own value transfer protocols for the digital transfer of value from peer to peer. However, other blockchain protocols may use TCP for communication between nodes in the network. Ultimately, the choice of protocol depends on the specific needs and design of the blockchain.
