There are two types of "fork" kriptocurrency forks: hard forks and soft forks.
### Hard Fork
The hard fork is the blockade of the blockade. Unrecognized on the new, and vice versa. Nodes that continue to run older versions of the software will see new transactions invalid. To mine a valid block on a new chain, all the nodes in the network need to be upgraded to the new rule.
### Fork Soft
The soft fork is the opposite of a hard fork, the soft fork is "backward compatible" in the sense that a transaction can be recognized by a new node. Unlike a hard fork, an unupgraded node will still see the new transaction as a valid thing. However, if the unupgrade nodes continue to mine blocks, the blocks will be rejected by upgraded nodes. Therefore, the fork needs to have hash power in the network to succeed. When supported by a small portion of the hash power in the network, it can be the shortest chain and become the sole of the network.
### Why is a fork going on?
Forks can be programmed and guided by developers who are dissatisfied with existing project elements. The latter is a highly contentious process for hard and full forks on governance issues associated with proposed solutions to problems such as scaling. In order for a successful fork, it takes a developer who believes in a new approach and knows it. In this way, the forks are important open source and important democratic. Garut is regularly incorporated, so happens, and finally accepted as a healthy component of the crypto ecosystem that allows people to build and determine what is most promising. This open source governance does not have a group that has absolute control over destiny.
## The latest Forks Governor
A recent major fork that is the Byzantine Ethereum guard (October 2017) is the first step in an upgraded step that is prepared into etereum to address the issue of scalability and the delivery of personal transactions. The hard pile planned recently is Monero's hard fork to introduce RingCT as an excellent means of privatizing deals (deeper about privacy coins here).
Two recent hard forks are Bitcoin Cash hard forks and Ethereal Classic hard forks. Bitcoin Cash as a hard fork to increase the block size of Bitcoin from 1MB to 8MB which will help scalability problems. This is the counterpart of the competing miners, so they can concentrate their strength on the hands of the big miners. Ethelium Classic becomes a hard fork to reply to a hack. Most communities (including core development teams) Throw a hard fork to reverse the effects of hack but smaller groups want to preserve blockchain as it used to, including hack. The smaller, hard-won and long-chain (including hack) groups become "Ethereum Classic" while the core development team and most of the public are open to the hack and retain the name "Ethereal" on a partially rolled back block that has no hacking effect.
Forks can also be spin-off coins that have a major difference from coins that are modeled but have many of the same technologies. Instead of floating from the existing blockchain these coins start fresh. Litecoin is one of the most famous spin-off coins and was created in 2011 as an alternative to Bitcoin with faster glowing times and greater supply of coins to address scalability issues.
### Fork the future
Forks will continue to be an important part of the growing cryptocurrency landscape. Will be a panorama for future ecosystems still working to overcome scalability and privacy issues. The fork allows crypto to be inflexible and in accordance with what is needed in the long run.
