On the day of the split, analysts forecasted that Bitcoin ABC (retaining the original name Bitcoin Cash) will likely prevail, receiving up to 60% of total hash power. As tensions rose, developers and miners within the BCH community increasingly moved toward the support of one or the other of two major personalities in the digital currency world, Roger Ver and Craig Wright. Ver and Wright are both known as strong supporters of digital currencies in general and Bitcoin Cash in particular, but they have been unable to reach an agreement about how to proceed in this case. Bitcoin Gold is a different hard fork that occurred in October 2017 with the goal of making Bitcoin mining a more equal process that requires only basic equipment. The two biggest Bitcoin hard forks are Bitcoin Cash and Bitcoin Gold, although there are others as well.

  • Ultimately, I don’t think any of the Bitcoin forks I have mentioned go far enough to become a truly useful global payment system.
  • Otherwise, there can’t be any full nodes managed by everyday users, which dramatically impacts the decentralization and security of a network.
  • These forks can be developed on larger blocks and result in a brand-new currency.
  • Both the United States and China have moved in a really rapid way into a new domain, and that is low Earth orbit.
  • Although each movement of funds is still posted to the public ledger, both the sender and the receiver remain private.

Well, in January of 2022, China put a satellite into space that had an arm that reached out and grabbed another satellite that was there in geosynchronous orbit. If they can’t target and they can’t communicate, they’re basically useless. So here, we need to slow down and explain what that means, why it’s so alarming, why nukes would ever be in space. Reporters heard that this had to do with Russia and with a new type of military threat.

What Is a Blockchain Protocol?

The complexity of changing rules has made Bitcoin unlimited largely unacceptable. A hard fork is a protocol upgrade to a blockchain network that is incompatible with older versions of the software. This is different from a soft fork, where older versions are able to interact with the new protocol. Sometimes an intentional fork is implemented to repair or resolve the history of a protocol in response to a catastrophic bug or hack.

In contrast, hard forks occur when the update is so fundamentally different from the previous version that the protocol is no longer backwards compatible. A notable example is the Bitcoin Cash (BCH) hard fork that took place in August of 2017. The BCH hard fork aimed to tackle Bitcoin’s scalability problem but took a very different approach than SegWit. In 2017, some of Bitcoin’s core developers wanted to increase Bitcoin’s maximum block size from 1MB to 8MB.

The nodes of a blockchain network are responsible for carrying out this specific process of verification, which is governed by the network’s protocol. In other words, the Bitcoin network is the sum total of all the decentralized nodes that carry out the Bitcoin protocol. The proposal for a hard fork did not exactly unwind the network’s transaction history.
