Why is Blockchain Good for You and What You Need to Know as a Beginner

“A Blockchain is a diary that is almost impossible to forge.” Blockchains are becoming incredibly popular. But how do they really work, for what purpose, and how can they add value to us at all? Blockchain is a term coined by a group of researchers in 1991 and was initially meant to put digital timestamps like a notary for digital documents so that they cannot be tampered with. Stuart Haber and Scott Stornetta worked on the first Blockchain. By the following year, Bayer, Haber, and Stornetta integrated Merkle trees into the design. It made the technology more efficient by allowing several document certificates to be collected into a block.

Each block in the Blockchain carries encrypted information distributed into multiple devices, that check and validate every bit of information added, all at the same time. It’s almost impervious to any form of tampering that a regular cyberattacker can easily do on a conventional network.

But it wasn’t until 2008, when a group who called themselves by the pseudonym “Satoshi Nakamoto,” adapted the technology for Bitcoin that the technology began to gain momentum. They released the whitepaper entitled Bitcoin: A Peer-to-Peer Electronic Cash System that described Bitcoin as a “purely peer-to-peer version of electronic cash.” It was when blockchain technology went public and was utilized by 2009. Since then, it has transformed into one of today’s leading ground-breaking technologies, conceived to impact every industry and sector of society.

By 2014, some experts began to look at Blockchain in a new light. They realized there was more to the technology than just running Bitcoin. It can revolutionize many other industries, from pharma to education, legal to government, and the like.

Security experts, for example, are now exploring Blockchain to bring defense systems against cybercrime and data breaches to a whole new level.

Blockchain removes intermediaries from being a peer-to-peer (P2P) system of data collection and sharing. As a result, proactive consumers are getting warmer to Blockchain as a viable alternative aside from the Internet. Blockchain technology can provide consumers with direct access to information without middlemen or third parties like the Internet does. In truth, Blockchain can protect consumers more than any internet network can. So, the P2P nature of Blockchain and the greater security and privacy it brings are making the technology more and more desirable for a market besieged by severe cyberattacks, data breaches, and theft.

Elements of a Blockchain:

  1. Data: It can be any data regardless of industry, such as home records, medical information, and even voting records.
  2. Hash Function: This is a mathematical formula that takes a variable number of characters and turns it into a string that has a fixed number of characters. Even a small change in this mathematical string creates an all-new hash.

Every hash function is unique and acts as a digital fingerprint. It identifies the block and all its contents. Once a block is created, the hash is automatically generated and distributed throughout the entire Blockchain. The use of hash functions makes it easy to detect any tampering with the data in any of the blocks throughout a Blockchain immediately.

3. Hash of the previous block: this technique makes a blockchain more secure. Except for the Genesis block, every block will have its unique hash function and the unique hash function of the block before it. If somebody would try to tamper even with a block, it invalidates the rest of the Blockchain because the hash function recorded on the next block will be different.

Characteristics of a Blockchain

Nicknamed the new and safer Internet, Blockchain also makes it possible for data to be distributed without duplication, different from the current structure the Internet has today. “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,” reveals Sally Davies of FT Technology (Blockchain Revolution: Understanding the Crypto Economy of the Future/Bradley Lakeman © 2018).

It has disruptive capabilities to existing systems the Internet has in place due to the Blockchain’s characteristics:

  1. Democratized: The blockchain network does not use central authority. The information in it is open for all in the network to see because it is a shared and immutable ledger.
  • Decentralized: The data in Blockchain is cryptographically stored inside. It is not owned by a single entity.
  • Immutable: As I mentioned, it is close to impossible to tamper with the data that is inside the Blockchain. All nodes or computer devices in a Blockchain, usually numbering hundreds, even thousands, would have to simultaneously approve any change made.
  • Transparent: All data created and stored in a Blockchain remains transparent. Everyone connected in the block is accountable for their actions. The data stored inside is also trackable because Blockchain acts as a distributed ledger system. Blockchain can be used beyond recording eCommerce transactions. It can be used for the medical database and keep binding agreements. It’s useful for tracking the delivery of goods, and tracing the origin and authenticity of items or contracts, (like artworks, land titles, antiques, and the like). It can also help safeguard all your personal credit records.
