Hard Forks: An Overview
A hard fork is a significant event in the world of blockchain technology and cryptocurrencies. It is a radical change to the protocol that results in a split in the blockchain and creates a new, incompatible version of the blockchain. In the following, you will learn more about what a hard fork is, how it works, what types there are, and how it is treated for tax purposes in Germany.
What is a hard fork?
A hard fork describes a significant change to the blockchain protocol, which results in the blockchain being split into two separate chains. This change is not backwards compatible, meaning that nodes that don't use the latest software version are no longer part of the new network.
The underlying code of the blockchain is being changed as far as the rules for transactions and blocks are concerned.
The change leads to the creation of a new blockchain while the old one continues to exist.
As a rule, a new cryptocurrency is created that exists parallel to the original one.
How does a hard fork work?
The process of a hard fork involves multiple steps and participants, including the developer community, miners, and users. Here's a step-by-step explanation of the process:
Proposed protocol
A change or improvement to the protocol is suggested, often by the developer community.

Changes to the protocol that introduce new regulations for the blockchain.
instance
Increasing block size, changing consensus mechanisms.

description
Hard forks that arise as a result of disagreements within the community.
instance
Bitcoin Cash (BCH) and Bitcoin SV (BSV) from the Bitcoin network.

Hard forks to introduce new features or fix critical security gaps.
instance
Constantinople upgrade on the Ethereum network.
The tax treatment of cryptocurrencies created by a hard fork can be complex. Here are some basic guidelines:
It is important to accurately document all transactions and the receipt of new coins. The duty to provide proof lies with the taxpayer. The following information should be collected:
A hard fork is a significant change to the blockchain protocol that results in the creation of a new, incompatible blockchain and usually a new cryptocurrency. The tax treatment of cryptocurrencies resulting from hard forks is subject to income tax in Germany and must be carefully documented.
