What is a Blockchain Protocol

In the real world, the energy consumed by the millions of devices on the Bitcoin network is more than Pakistan consumes annually. For all of its complexity, blockchain’s potential as a decentralized form of record-keeping is almost without limit. From greater user privacy and heightened security What is a Blockchain Protocol to lower processing fees and fewer errors, blockchain technology may very well see applications beyond those outlined above. By spreading its operations across a network of computers, blockchain allows Bitcoin and other cryptocurrencies to operate without the need for a central authority.

Scott Stornetta, two researchers who wanted to implement a system where document timestamps could not be tampered with. But it wasn’t until almost two decades later, with the launch of Bitcoin in January 2009, that blockchain had its first real-world application. The hash is then entered into the following block header and encrypted with the other information in the block. Because there is no way to change a block, the only trust needed is at the point where a user or program enters data. This aspect reduces the need for trusted third parties, which are usually auditors or other humans that add costs and make mistakes.

How do blockchain protocols work?

By using smart contracts — i.e., self-executing code stored and accessible on an immutable blockchain —  companies and individuals can avoid the expense and often the ambiguity of engaging with third parties to accomplish routine business. A number of companies are active in this space providing services for compliant tokenization, private STOs, and public STOs. They are distributed ledgers that use code to create the security level they have become known for. A blockchain allows the data in a database to be spread out among several network nodes—computers or devices running software for the blockchain—at various locations. This not only creates redundancy but maintains the fidelity of the data.

  • The block size debate has been and continues to be one of the most pressing issues for the scalability of blockchains going forward.
  • DLTs allow members to securely verify, execute, and record their own transactions without relying on a middleman, rather than requiring a central authority to update and communicate records to all participants.
  • Transactions follow a specific process, depending on the blockchain they are taking place on.
  • They are distributed ledgers that use code to create the security level they have become known for.
  • Thus, blockchain protocols are an essential foundation for the entire blockchain ecosystem.

Let’s dissect the various types of blockchain protocols and their characteristics. Decentralization, transparency, immutability, enhanced security, reduced fraud, faster and more efficient transactions, and improved supply chain management are blockchain protocol benefits. In crypto or any other information technology system, protocols are the rules that govern data sharing between computer systems.

These personal health records could be encoded and stored on the blockchain with a private key so that they are only accessible to specific individuals, thereby ensuring privacy. For instance, imagine that a hacker runs a node on a blockchain network and wants to alter a blockchain and steal cryptocurrency from everyone else. If they were to change their copy, they would have to convince the other nodes that their copy was the valid one. Protocols are basic sets of rules that ensure data sharing between computers or computing systems.

The protocol-based design allows for better service of permissioned networks. A Blockchain protocol runs on top of the Internet on a peer-to-peer network of computers that all run the protocol and have an identical copy of the transaction ledger. This allows P2P value transactions without a middleman through machine consensus. With the increasing number of blockchain systems appearing, even only those that support cryptocurrencies, blockchain interoperability is becoming a topic of major importance.


This is probably because public distributed ledgers bear similar operational resemblances to the public internet itself. In the field of computer programming, protocols refer to a set of rules that determine how a system should function. Similarly, blockchain protocols are a set of codes and regulations that govern the operations of a blockchain network. Blockchain itself a file – a shared and public ledger of transactions that records all transactions from the genesis block (first block) until today.

The blockchain industry’s definition for the word “protocol” is essentially any distributed ledger-based service, including the distributed ledgers themselves, that can receive and respond to programmatic requests. Similarly, if a decentralized autonomous organization (DAO) offers an automated liquidity pool (LP) that includes various forms of cryptocurrency liquidity via a software programmable interface, that LP is considered to be a protocol. Through public-key cryptography (PKC) — which gives users a public key for receiving transactions and a private key for sending transactions — blockchains allow users to remain pseudonymous and for the transfer of data to remain secure. A blockchain is a distributed database or ledger shared among a computer network’s nodes. They are best known for their crucial role in cryptocurrency systems for maintaining a secure and decentralized record of transactions, but they are not limited to cryptocurrency uses. Blockchains can be used to make data in any industry immutable—the term used to describe the inability to be altered.

The nature of blockchain’s immutability means that fraudulent voting would become far more difficult. For example, a voting system could work such that each country’s citizens would be issued a single cryptocurrency or token. Of course, the records stored in the Bitcoin blockchain (as well as most others) are encrypted.

What is a Blockchain Protocol

A private blockchain can be run behind a corporate firewall and even be hosted on premises. Crypto protocols govern how a blockchain network can function, its security, and what its users can do with it. For example, they usually include a consensus mechanism such as proof-of-work (PoW) or proof-of-stake (PoS) that governs how transactions are processed and validated securely. So, as you now know, the layer 1 blockchain protocol is the main blockchain network in charge of on-chain transactions and core functionality.

Blockchain builds on the idea of P2P networks and provides a universal data set that every actor can trust, even though they might not know or trust each other. It provides a shared and trusted ledger of transactions, where immutable and encrypted copies of information are stored on every node in the network. Economic incentives in the form of native network tokens are applied to make the network fault tolerant, and attack and collusion resistant. Openchain is an open-source distributed ledger technology that provides support to organizations to issue and manage digital assets. For example, it can provide support to a start-up company that sells security tokens or equity tokens.

  • The two approaches here to make the base protocol more efficient are things like consensus protocol selection and sharding.
  • Timing would be everything in this type of attack—by the time the hacker takes any action, the network is likely to have moved past the blocks they were trying to alter.
  • They are supposed to verify the identity of each customer and confirm that they do not appear on any list of known or suspected terrorist organizations.
  • This consensus is governed by an algorithm fed into the protocol layer of the blockchain.
  • This blockchain solution can help turn any developer into a blockchain developer.
  • The blockchain protocol would also maintain transparency in the electoral process, reducing the personnel needed to conduct an election and providing officials with nearly instant results.
