indian headpiece jewelry wholesale What is hard fork and soft fork in Bitcoin? What are their own characteristics?

wholesale solid gold jewelry supplies In simple terms, because of different compatibility, hard forks and soft forks are generated. Soft forks are temporary, while hard forks are permanent.
Permanent differences occur in the blockchain. After the release of the new consensus rules, some nodes that have not been upgraded in time cannot verify the blocks generated by the upgraded nodes. At this time, the hard fork will happen. For the hard fork, the definition of the industry is like this. Hardbar means that when the Bitcoin's block format or the transaction format (that is, the "consensus" that everyone is familiar with), nodes without upgrading will refuse to verify that it has already been verified. Complete the block produced by the upgraded node. The upgraded nodes can verify the block generated by the unlimited node. Then everyone continues the chain that they think is correct. Therefore, two chains are divided into two chains: new and old chains.
has the following characteristics:
1, there is no forward compatibility, the previous version will not be available, and it needs to be forced to upgrade;
2, there will be a bifurcation at the level of the blockchain. The two chains, an old chain, and a new chain of fork;
3, you need to agree to the fork upgrade at a certain point in time, and you will enter the old chain if you disagree.

Is when the new consensus rules are released, the nodes that do not complete the upgrade will generate illegal blocks because they do not understand the new consensus rules, which will generate temporary forks. This temporary fork is also called soft fork. Regarding the soft split fork is defined like this: When the soft fork refers to the change of the data structure of the Bitcoin transaction, nodes without upgrades can verify the block generated by the upgraded nodes, and the nodes that have been upgraded can also be verified that there is no no verification. Blocks generated by upgraded nodes.
The soft fork has the following characteristics:
1, which has good compatibility. Some of the previous versions of the functions are available and can be upgraded without upgrading.
2, there is no bifurcation chain at the level of the blockchain, but the block of the chain of the composition is divided into new and old blocks;
3, for a long time, you can allow no upgrade to continue, continue to continue, continue Use the original version to generate old blocks and coexist with the new district.
