Blockchain in the Future: What it Means to Businesses and How it Works

The blockchain is a digital, decentralized ledger that can record transactions between two parties efficiently and in a verifiable and permanent way.

It has the potential to disrupt a variety of industries and has already begun to do so. This article will highlight the ways blockchain is already being used, as well as its potential in the future.

How Does Blockchain Work?

Blockchain works as a distributed ledger – a type of database that is owned, managed, and controlled by many entities. These entities are known as “nodes.” A ledger is a database that keeps track of transactions between parties, including the transfer of assets. Nodes are connected to one another through a peer-to-peer (P2P) network. Transactions are added to the ledger by recording them in a database with the use of cryptography and a mathematical formula. Once recorded, the database can’t be altered retroactively without the alteration of all subsequent blocks and the consensus of the network.

Blockchain Benefits

Consensus: A blockchain network has a consensus mechanism that enables the network to agree on the transaction record without the need for a central authority. This results in higher levels of trust and security.

“Transparency: All transactions on a blockchain network are visible to the entire network. This makes the blockchain a transparent and trustworthy source of information.” Andrew Drow, WellPCB 

“Immutability: Once a transaction is recorded in a blockchain, it is extremely difficult to alter. This makes the blockchain immutable, which means it’s not susceptible to the same degree of fraud or manipulation as other types of systems.” Amelia, Stream Digitally

Fraud Resistance: Blockchain networks use a combination of cryptography and network economics to make fraud virtually impossible. This means that even if an individual tries to falsify data, it can’t be altered retroactively without the alteration of all subsequent blocks and the consensus of the network.

Blockchain Disadvantages

Cost: Currently, the infrastructure to support blockchain is still relatively immature. As such, the technology is not yet available to the general public, but rather is available only to select financial institutions and other organizations. This could change in the future, however, as the technology continues to develop.

Performance: As blockchain networks become more mature, their performance will increase. However, currently, due to their youth, performance is relatively poor, and networks can experience significant backlogs of unprocessed transactions.

Inconsistency: While it’s nearly impossible to falsify data or reverse transactions on a blockchain, it’s also pretty much impossible to make the blockchain 100% consistent. This means that some nodes may record transactions in a different order than other nodes. As such, the blockchain may be susceptible to “race condition” errors.

How to Build a Blockchain

The first step toward building your own blockchain is to decide what kind of blockchain you want to build. There are many different types of blockchains.

Server-based: If you’re planning to build a blockchain that will serve a single company or organization, a server-based blockchain may be the best option for you. A server-based blockchain doesn’t have a public network. Rather, it’s an internal network that companies use for recording transactions. One popular example of a server-based blockchain is the Hyperledger Fabric.

Community-based: A community-based blockchain allows public access to the blockchain. This means that anyone can join the blockchain as a “validator” and help maintain and secure the blockchain. Validators are individuals who contribute computing power to help process transactions and maintain the network. The public network of a community-based blockchain may be maintained by a variety of different organizations or individuals. One example of a public community-based blockchain is Ethereum.

Private: A private blockchain is intended only for a specific group of organizations to perform transactions that are restricted to participants in the blockchain network. The most common use of a private blockchain is to issue shares or bonds.

Conclusion

In short, the blockchain is a digital, decentralized ledger that can record transactions between two parties efficiently and in a verifiable and permanent way. It has the potential to disrupt a variety of industries and has already begun to do so. This article will highlight the ways blockchain is already being used, as well as its potential in the future.
