Cryptocurrency is a type of virtual currency that uses cryptography to secure transactions that are digitally recorded on a distributed ledger, such as a blockchain. A transaction involving cryptocurrency that is recorded on a distributed ledger is referred to as an “on-chain” transaction; a transaction that is not recorded on the distributed ledger is referred to as an “off-chain” transaction.
Every bitcoin transaction must be added to the blockchain, the official public ledger of all bitcoin transactions, in order to be considered successfully completed or valid. The work of validating transactions and adding them to the blockchain is done by miners, powerful computers that make up and connect to the network. Miners spend vast amounts of computing power and energy doing this for a financial reward: with every block (a collection of transactions not exceeding 1 MB in size) added to the blockchain comes a bounty called a block reward (currently 6.25 BTC), as well as all fees sent with the transactions that were included in the block
Again due to the fact that a block on the bitcoin blockchain can contain no more than 1 MB of information, transaction size is an important consideration for miners. Smaller transactions are easier to validate; larger transactions take more work, and take up more space in the block. For this reason, miners prefer to include smaller transactions. A larger transaction will require a larger fee to be included in the next block.
Blockchain Wallet users will always have options when it comes to bitcoin transaction fees. Our wallet uses dynamic fees, meaning that the wallet will calculate the appropriate fee for your transaction taking into account current network conditions and transaction size. You can choose between a Priority fee and a Regular fee. The Priority fee is calculated to get your transaction included in a block within the hour. The Regular fee is lower, and is for users who can afford to be a bit more patient; a confirmation for a transaction that includes a Regular fee will typically take a bit more than an hour.
Blockchain technology connects millions of computers (much like the internet) that can all store/host encrypted copies of these records. So instead of one record keeper, you have millions of record keepers called 'nodes'. One record keeper can tamper records, collude with third parties and commit fraud, but now there are a million nodes who are keeping a watch on each other. Much like the internet provides an infrastructure for communication, blockchain provides an infrastructure for record keeping.
Regulation can solve this concern. Across the world, regulators (including in the US, Singapore, Japan, Dubai and UK) have evolved regulations to solve this issue. Licensed intermediaries (crypto-exchanges) can help the regulator maintain oversight and control over cryptocurrency transactions through mandatory requirements such as extensive know-your-customer or KYC checks on traders, taking anti-money laundering measures and maintaining transaction records. This is how existing financial institutions such as banks and stock exchanges keep track of financial transactions and verify customer identity. A dashboard can be made accessible to all relevant authorities to provide real-time trading data in relation to all exchange users in India, and trade of cryptocurrencies can be restricted to only those users whose addresses have been whitelisted by licensed exchanges in India. These features can provide substantial controls to the regulator to monitor the flows of cryptocurrencies and restrict them to verified/legitimate users. We also propose the adoption of Aadhar-based e-KYC, mandatory capitalization requirements, creation of a central repository with details of blacklisted users and formation of an investor protection and education fund.
Cryptocurrencies have an inherent utility as a technology. People also buy them to use them as a monetary asset, and demand and supply determine their value. Now this is similar to buying land – you can buy land to use it (build a house etc) or invest in it. Likewise, people invest in cryptocurrencies. These investments are used by cryptocurrency developers to fund further development of their projects. Given the tremendous potential of this technology, investments here will reap high returns. Taking a note of this companies such as Tesla are investing their treasury reserves in to bitcoin.
