What is blockchain Technology?
In recent years, blockchain or blockchain technology is a word heard a lot when investing in the crypto spectrum. However, many people are not aware of the nuances of the term and its origin and usage. This reading focuses on blockchain and how it powers a cryptocurrency.
Define blockchain
Blockchain technology is basically a system of recording information in a way that makes it extremely difficult or impossible to change, hack or defraud the system. It is a chaining technique, meaning that each step is closely related to and dependent on the previous one.
A blockchain is an essential digital ledger of transactions. It is replicated and distributed across a network of computer systems on a blockchain, which keeps a record of every transaction.
Each block on the chain contains a number of transactions. Every time a new transaction occurs on the blockchain, a record of that transaction is added to each participant’s ledger at the same time to avoid fraud.
This decentralized database managed by many participants is known as distributed ledger technology (DLT). Blockchain is a type of DLT, where transactions are recorded with an immutable cryptographic signature called a ‘hash’.
In other words, if a block is changed anywhere in the world, it will be immediately apparent that tampering is taking place within the system. If hackers wanted to corrupt the blockchain system, they would have to change every block in the chain at the same time.
This task is apparently impossible, thanks to the anonymity in the network, in all the distributed versions of the chain, which are spread all over the world.
The powerful and oldest blockchains, such as Bitcoin and Ethereum, are constantly and steadily growing globally as blocks are being added to the chain, which significantly adds to the security of the ledger.
Features of DLT
-
Programmable: A blockchain is programmable, which means smart interaction
-
Secure: A block is secure because all records are individually coded.
-
Anonymous: The identity of the participants is either anonymous or artificially anonymous. This is one of the biggest and most argued features of blockchain.
-
Unanimity: All network participants agree on the validity of each record at a particular point in time.
-
Timeliness: Transactions in the block chain have a time stamp.
-
Immunity: Any valid record on the blockchain cannot be reversed or changed.
-
Distribution: All network participants have a copy of this ledger to make it completely transparent.
The thrill of blockchain technology
History shows that there have been many attempts to create decentralized digital money, which never achieved success until late 2008, when the first coded currency or cryptocurrency came into existence, known as ‘Bitcoin’. goes.
Every legal tender or modern-day currency operates on the trust factor. Users of a particular currency know that the central bank or government of the particular region is backing the currency, which gives it value. If the government withdraws its support, a currency bill is as good as another piece of paper.
The prevailing issue in digital currency is trust. If someone creates a new currency called ‘ABCD’, the question arises how can one believe? Won’t they give themselves enough of a particular currency or steal the user’s currency for themselves, or will the user’s share remain the same in the whole?
Bitcoin’s design tries to solve these problems by using a specific type of database called a blockchain. Also, only 21 million bitcoins can be mined, meaning that if a user holds one bitcoin, his share will remain 1/21,000,000 for as long as he holds the bitcoin.
In most common databases, someone in charge can easily change entries. Blockchain is different because it has no central authority, and everyone is treated equally. The shares thus granted remain fixed in perpetuity as the initial details or ante-dated information cannot be changed.
Let’s understand it another way, if the government wants, it can print as much domestic currency as it wants in the economy. These practices may sound attractive, but an excess of supply will lead to inflation in the economy.
This means that if someone has $1,000 out of $100,000 in the economy. Currency holders account for 1% of the economy. However, if the authority doubles the currency to $200,000, the currency’s power will be reduced from a $1,000 share to less than 0.5%.
Blockchain addresses the problem once the maximum supply is reached and the stock is stable as no mining can be done. What’s more, bitcoin or blockchain-backed coins cannot be counterfeited, hacked or double-spended. So those who own this money can believe that it has some value.
Disadvantages of Blockchain
Not everything is excellent in blockchain technology as it has its own challenges, which need to be addressed significantly. The barriers to application of this new-age technology are not just technical. They are real life challenges, which can pose a serious threat to the economy.
Some of these challenges are political and regulatory, to say nothing of the thousands of hours spent in custom software design and back-end programming required to integrate blockchain into current business networks.
Cost: Blockchain can save on transaction costs, but the technology is not free yet. The ‘Proof of Work’ system used to validate transactions consumes a lot of energy and computational power.
In the real world, the power of the millions of networked megacomputers on the bitcoin blockchain is equivalent to the annual electricity consumption of several European countries. If electricity costs up to $0.05 per kilowatt-hour, the hardware expenses could add up to mining costs of up to $7,000 per coin.
Despite the high cost, users continue to validate transactions on the blockchain because they are rewarded for it. Blockchains that do not use cryptocurrencies still require miners to be paid or incentivized to validate transactions.
However, various solutions have emerged to address this problem. There are several blockchains, which are claiming 50,000 transactions per second.
Legality and misuse: Blockchain may be a ‘hack proof’ and ‘duplication proof’ technology, but it also allows illegal activities on the network. There are many activities carried out on the dark web, whose legality is always questionable.
This gives anyone access to financial accounts but also allows criminals easy transactions. Users are kept anonymous, making them impossible to trace. Such mediums of exchange can also be used in terrorism.
Regulatory issues: Several global governments have raised their concerns about the crypto space and cryptocurrencies. However, they could not stop the Bitcoin or Ethereum networks from growing.
Governments could theoretically make it illegal to own cryptocurrencies or participate in their networks. But his decision is being challenged on various legal platforms.
The second concern is that by moving to such a decentralized or anonymous currency, the government would weaken its central bank, which has thus far monopolized the currency used in a particular currency. Hence it is a serious threat to the economic stability and existence of the country.
Conclusion
The history or roots of blockchain technology dates back to the early 1990s. It’s been a three-decade-old concept, and people born in that era have increasingly embraced it. However, the technology, its use and access have still come under public scrutiny over the years, especially in recent years.
This new age technology has immense potential, and businesses around the world are speculating about its potential and where it is headed in the coming years. Blockchain, as a technology, is gaining acceptance.
Not only with many practical applications for Bitcoin or Ethereum, blockchain technology is already being implemented and explored, but it exists to make operations more accurate, efficient, secure, and cheaper, only when the given challenges are met. And legitimate issues are resolved.
blockchain technology is a word heard a lot when investing in the crypto spectrum. However, many people are not aware of the nuances of the term and its origin and usage. or medium of exchange. However, the question has not shifted from ‘if’ to ‘when’.
