How Does Blockchain Work?

Instead than having a primary administrator like a traditional database, a digital ledger has a network of replicated databases that are synchronized through the Internet and visible to anyone on the system. Blockchain networks can be public, like the Internet, where everyone in the world has access to it, or they can be private, where there is a restricted membership that is similar to an Intranet.

When a digital transaction is completed, it is grouped together with other transactions that have occurred within the last ten minutes. They are grouped into a cryptographically protected block that is then sent out to the entire network. Miners are members of the system with high levels of computing power that compete to validate the transactions in the block by solving complex coded problems. The first miner to correctly answer the challenge and confirm the block receives a reward, usually in the form of a coin or token.

After the block of transactions is validated, it is timestamped and added to the chain in linear, chronological order. New blocks that have been confirmed are then linked to the older blocks, forming a chain of blocks that show every recorded transaction made in the history of that particular blockchain. The entire chain is updated constantly so that all of the ledgers in the network is the same, giving each member of the blockchain network the ability to prove who owns what at any given time.

The decentralized, open, and cryptographic nature of blockchains allow members of the network to trust each other and make peer-to-peer transactions, effectively eliminating intermediaries. It also brings with it unprecedented security benefits.

Is Blockchain Technology Secure?

Through the use of hash functions and timestamps, blockchain has made it so that the data in the chain cannot be changed or tampered with once it has been verified. Since you can’t overwrite the data in a blockchain, manipulating the data is impractical, ultimately securing the data and eliminating the centralized points that hackers and cybercriminals often target.

The key to blockchain’s security is that any changes that are made to the database are immediately sent to all of the users to create a secure and established record. All the users on the network receive a copy of the data keeping the overall database safe and secure, even if a handful of network users are hacked.

By storing data and financial information across a network of computers, it becomes much more difficult for hackers to compromise data. Rather than having to breach a single server, making a fraudulent transaction or falsifying a balance on a blockchain can only be accomplished if the majority of the network is compromised. Hacking into a single server is extremely difficult, even for the most accomplished cybercriminals. Being able to compromise more than half of the servers to falsify records on the blockchain is practically impossible because for hackers to successfully change information in the blockchain, they would need to breach each node in the chain simultaneously.

The decentralized and tamper-proof nature has made blockchain technology increasingly popular beyond its original intended function as a way to support digital bitcoin transactions and is starting to pique the interest of numerous industries that could utilize blockchain technology for their advantage.

What Are Some Other Applications for Blockchain?

There are several other applications for blockchain technology that don’t involve recording bitcoin transactions. According to the Sally Davies, a reporter for the Financial Times, “Blockchain is to bitcoin, what the Internet is to email. A big electronic system, on top of which you can build applications. Currency is just one.” Bitcoin is only one small application supported by blockchain. Blockchain technology is full of endless possibilities.

Payments and Cryptocurrencies

The most popular blockchain application is cryptocurrency because along with being the first application, it also has the most extensive network of users. In fact, Bitcoin has become so popular that restaurants, stores, and bars are starting to accept it as payment. It has also been used to cope with hyperinflation in Venezuela. The smart contract that is built into Ethereum’s cryptocurrency allow for a variety of deals to occur automatically once pre-negotiated terms have been met.

Trade

The blockchain, as well as cryptocurrencies, will have a tremendous impact on business. The reduction or removal of transaction fees, faster verification times, and the elimination of errors will make international and domestic trade easier than ever.

Crowdfunding

Blockchain will dramatically change how startups and businesses raise capital. Kickstarter, one of the most popular fundraising sites allows just about anyone to find financial backing from a broad audience rather than through traditional means like venture capital funds and banks. They charge a five percent fee for using the service. With blockchain, these fees will be eliminated since the network allows for immediate verification and smart contracts allow transactions to be completed only when a project is fully funded.
