Recent News – Tesla Inc. expects to allow customers to pay for its electric vehicles with Bitcoin soon, a move that can expand how the most popular cryptocurrency is used for real-world transactions.
For the past few years, bitcoin has become more of a household name as an investment product. While people are fancying incorporating cryptocurrency into their investment portfolio, many are not aware of the technology working behind it – blockchain, and how its applications can go quite beyond the financial sector. The technology is capable of supporting various applications across multiple sectors like supply chain, manufacturing, healthcare, real estate, and so on. Companies like Pfizer, AIG, Walmart, Siemens, IBM, and Unilever have already started leveraging the potential of blockchain technology.
While many people find cryptocurrencies, bitcoin, and blockchain as complex terms, blockchain is nothing but a specific type of database. It is different from a typical database in the way it stores information. Blockchain stores the data in blocks that are then chained together through peer-to-peer nodes. This kind of storage is commonly known as a digital ledger. While the data in common databases can be easily tampered with, the information stored in digital ledgers is highly secure. Blockchain uses a digital signature feature, which makes it impossible for anyone to corrupt or change the data without a specific digital signature.
A lot of companies around the world are working on blockchain-based projects so as to use the technology in ways to help the common man other than just recording transactions. In light of this trend, the demand for blockchain developers is reaching new heights every year. Professionals are learning the Blockchain basics by going through various tutorials and online courses available online. For such aspirants, we have listed some of the best courses you can take to learn the fundamentals of blockchain technology. Moreover, the mentioned courses are free of cost, and you can learn them anytime at your convenience.
