Of course, over time as relative demand for tokens on the two networks changed, the relative price of Bitcoin and Bitcoin Cash changed as well. What we hope is clear from the above discussion is that hard forks, in principle, allow network users and developers to modify almost any aspect of a blockchain protocol. Narrowly, these changes have been limited to software upgrades intended to improve the performance of the network, such as changes in the hashing algorithms used to verify blocks in the blockchain. However, as illustrated above, some proposed changes may involve a redistribution of value across network users. More generally, such “upgrades” could be used to change the pre-determined supply of cryptocurrency. Or, in principle, it would appear that users could agree to remove all cryptocurrency held in a specific wallet and re-allocate it to other users in the network. Again, these are feasible changes that could be implemented by way of a hard fork.
The first change in Polygon’s new fork involves an adjustment to how it sets gas fees – a kind of tax one pays out to a blockchain in order to transact on it. With the fork, Polygon aims to reduce the spikes in gas prices that tend to occur when there is a lot of activity on the chain. Ethereum scaling project Polygon has announced a proposed hard fork to its proof-of-stake blockchain.

Sun had earlier backed the idea of executing an Ethereum hard fork instead of transitioning the entire blockchain to PoS consensus. Hackers can then use this transaction data to remove coins from your wallet. Receiving addresses are generally anonymous, so miners can’t see that it is a hacked transaction.
- This is what makes it differ from a soft fork, which changes the protocol and, in effect, erases the original version.
- Well, everyone except for a substantial number of investors, who saw no need to go to such extreme lengths and have an ETH hard fork.
- Constantinople is set to be a key milestone on the company’s plans to move the protocol from Proof-of-Work to Proof-of-Stake in the 2.0 version.
- Bitcoin forks have got a lot of interest because when a new coin is created, those who have the original coin will get the same value in the new coin.
Hard forks create a completely new bitcoin currency and reject all transactions from the legacy version, becoming incompatible with the original blockchain. It is useful here to describe the hard fork process in more detail. First, a “fork” in a blockchain is a regular or common occurrence.
A Normative Framework for Blockchain Design With Fixed Features
What if a whale knows that a hard fork is around the corner and that it will receive a new coin for every original one it has. This will provide a strong incentive for the whale to increase its share of the original currency. Its size means that it can artificially increase the price of the main currency right before the fork, because large players like whales buy everything they can find until the day of the fork. Forks occur when the currency developers or users decide that something fundamental needs to change. This can be due to a major security flaw, as was the case with Ethereum, or a general disagreement within the community, as we saw with Bitcoins and Bitcoin Cash. For some early forks, the creation of a new currency was needed because of small block sizes, the time it took to confirm transactions and privacy issues.
