Blockchain is a distributed ledger technology that changed from the Internet of Information and represented a second phase of the Internet. While the first era of the Internet democratized the exchange of information, blockchain promises to democratize the business of real-world values. Blockchain emerged in late 2008 amid the global financial crisis.
Satoshi Nakamoto introduced a new protocol for a “Peer-to-Peer Electronic Cash System” and created a digital currency or cryptocurrency called Bitcoin based on blockchain technology.

They are not stored in a bank arch or recorded anywhere in an electronic file; they are a global table or repository of all transactions that use the resources of an extensive peer-to-peer network to review and approve every bitcoin transaction. But blockchain is more than just cryptocurrencies; blockchain has more applications, and investors realize the business potential and money flows in at high speed.
Blockchain has five characteristics that make it a potentially transformative and disruptive technology:
A protocol creates a set of rules in the form of distributed mathematical calculations.
Also that guarantee the integrity of data exchanged between many computing devices without going through a trusted third party.
Each chain block runs on computers provide by volunteers from around the world, and there is no central database to be hacked, corrupted, or shut down.
This means that money, stocks, bonds, intellectual property rights, music, cars, Also you can even votes can be store and exchange without an institution or middleman.
Smart Blockchain Contracts
Smart contracts are just like regular contracts; nonetheless, the contract rules are apply to a blockchain in real-time, eliminating the middleman and increasing liability for all parties involve in a way that smart contracts cannot. This protects companies’ time and money while ensuring obedience for everyone involved.
Also, Blockchain-based contracts are gaining popularity as sectors like government, healthcare, and real estate discover the benefits. Below are examples of how companies use blockchain to make contracts smarter.
Blockchain and IoT
The Internet of Things (IoT) is the following rational prosperous in blockchain applications. IoT has millions of applications and many security issues.
A proliferation of IoT products means better opportunities for hackers to steal your data from Amazon Alexa to a smart thermostat.
Blockchain-infused IoT adds a higher equal of security to prevent data breaches.
Also using technology’s transparency and virtual incorruptibility to keep things “smart.”.
Below are some companies using blockchain to make the Internet of Things safer and more innovative.
According to AARP, as many as 42 million Americans were victims of identity fraud in 2021 alone. Deception on this scale can happen from forged documents to personal hacking files.
The government could see a radical drop in identity theft claims by storing social security statistics, birth certificates, birth dates, and sensitive information on a dispersed blockchain ledger. Also, Here are some blockchain-based companies at the lead in identity security.
