However, while centralized service providers easily update their software with new features at the touch of a button, decentralized applications, such as cryptocurrency on a blockchain, require a different, more complex approach.
For example, blockchains are decentralized open-source protocols that lack a central authority. As such, the decision to upgrade to the protocol requires the consensus of all users on the network.. This unique process of updating or upgrading a blockchain is called a fork. Forks can be categorized into either soft or hard forks, depending on their purpose. But first, let us look at what it means to have a fork on the blockchain. Understanding Forks on a Blockchain At its most basic level, a blockchain is like a set of data blocks , connected by secure cryptographic keys that form a chain of blocks going back to the very first block.
Therefore, one can picture the blockchain as a straight path made of blocks linked to one another. Because the blocks are chained together through a consensus that all of the blocks agree upon, any upgrade to the system requires a change of consensus on all of the blocks. Such a consensus is unlikely to occur because the blocks are linked through a functionally immutable set of rules.
Thus, instead of rewriting each block, changes to a blockchain are often achieved through the use of a fork. A fork is an event on the blockchain that copies the original software and adds the desired changes to it. Because the two blockchains cannot coexist, the new blockchain splits into two branches, forming a fork-like diversion from the main blockchain.
Who Determines a Fork Formation? Because the blockchain is not run by any central authority, it is the responsibility of the participants on the network to agree on the way forward and implement changes that increase the overall efficiency. Blockchains, however, feature different subsets of participants ranging from miners to full node users and developers.
So, who gets the final say on what changes should be implemented on the network? Because each subset contributes differently to the network, some participants have more voting power than others. For example, miners, who secure the network by dedicating computational resources for block validation, tend to determine the security and popularity of the fork versions. Most open-source blockchains allow for an overlap of responsibilities and, therefore, a shared responsibility on the fork formation process.
Other subset roles include developers who create and update the code that runs inside the blockchain , and full node users who act as the backbone and auditors of the network, as they validate and maintain the history of the blockchain. What is a Hard Fork? If there is a cryptocurrency running on an old blockchain , for example, a fork on that blockchain will result in the creation of a second cryptocurrency on the new, forked blockchain.
With a hard fork, the rules of the blockchain protocol are updated or changed so that the old blockchain and the resulting blockchain are incompatible. This means that the old nodes will not accept the newly updated blocks, and the new blockchain will operate on new rules that continually reject blocks from the old blockchain.
For example, a hard fork was created on the Bitcoin blockchain over a disagreement in the Bitcoin community over the best approach for scaling the network. On one side of the argument were members who wanted to increase the block size,. On the other side were those members who opposed such changes.
Subsequently, those who wanted to increase the size of the block followed the Bitcoin Cash fork, while those who opposed such changes remained on the main Bitcoin network. For this reason, while both coins i. Correct Security Risks - Blockchain software may have inherent security vulnerabilities that need to be fixed before a hacker takes advantage of them.
In these cases, a hard fork may be required to protect the larger ecosystem. Reverse Previous Transactions - A hard fork can be used to roll back previous transactions on a blockchain. This was seen in the case with the hard fork to reverse the hack on the DAO decentralized autonomous organization on the Ethereum blockchain.
The IRS discusses cryptocurrency forks in its new cryptocurrency guidance and ruling, Your cost basis in the newly received cryptocurrency becomes the income you recognized. For example - If you held 2. If you do not receive new cryptocurrencies after a hard fork, you will not have any taxable income. The amount of income recognized should be determined using the fair market value of the cryptocurrency at the time.
If you did not receive any cryptocurrency when an airdrop event occurred, you do not recognize income as you did not receive the property. Cryptocurrency Tax Software You can leverage cryptocurrency tax software like CoinLedger to automatically account for all of your hard forks and airdrops in accordance with the new IRS guidance.
Simply import all of your cryptocurrency trades and transactions into the platform. In step 2 of CoinLedger, you can add any cryptocurrency you have received as a result of an airdrop or hard fork. Every single one will be assigned with the appropriate cost basis and fair market value in USD at the time of receipt, allowing you to immediately generate your necessary tax documents with the click of a button.
