- The difference between a softfork and a hardfork is that hardforks make previously invalid blocks valid, whereas softforks do the exact opposite; they make once valid blocks invalid.
- The reason one would do a hardfork would be for consensus rules changing.
- The risk to performing a hardfork is the community splitting, simultaneously making the hash power split.

Hi everyone,
- A soft work makes previously invalid blocks become valid (it’s an expansion). A hard fork makes previously valid blocks become invalid (it’s a contraction).
- To change consensus rules.
- There is a split of the chain, a split of the community, a split of the hash power which can represent a security issue.

A reason you would do a hard fork is to expand the network.
-
The risks of performing a hard fork include splitting up the community, creating a new currency, and splitting the chain and hash power.

The Softfork update makes previously valid blocks invalid, whereas Hardfork updates make previously invalid blocks valid. Softforks are a contraction of the consensus rules, while Hardforks are a expansion of consensus rules.
- What are some of the reasons why you would do a hardfork?
The update is clear to everyone. You expand the rules, which can create a new currency.
- What are some of the risks with performing a hardfork?
- split the chain
- split the community
- split the hashpower, which leads to reduced security

A soft fork update is a contraction of the rule set and blocks that were previously valid become invalid. A hard fork update is an expansion of the rule set and blocks that were previously invalid become valid.
-
To expand the rule set, to improve (tokenomics) or change direction (vision) dealing with a bug or hack.
-
Risks involve splitting the chain and the community. Security vulnerability as a hash power is split among miners.

- What is the difference between a softfork and a hardfork?
The difference in the changes of the block validation rules. Soft - previously correct is incorrect after changes and Hard - previously incorrect becomes correct after changes. - What are some of the reasons why you would do a hardfork?
I think it’s some performance or quality improvements. - What are some of the risks with performing a hardfork?
Decreasing security of the network because of splitting the total hash power. Also community splitting can be a risk.

- A hardfork changes the rules of the protocoll. It will create a new chane and nodes that dont update cant participate at the new protocoll. A softfork is when the protocoll is changed in the frame of the rules of the protocoll. Here can also not updated miners and nodes participate in the updated/non updated blockchain and the “best” version of a porotocoll will win in the end or will be mostly accepted.
Its like if you update your whatsapp you still have whatsapp Thats a softfork. But you cant send from Whatsapp to Telegram a message even you have the same phonenumber with this apps. Thats the hardfork…
-
To make big changes to the protocoll. To create your own coin or Blockchain. Everybody who wants to participate can by there own rules.
-
The Network can splitt. The community can splitt. You may dont find wide acceptence of you fork. you cant participate in the old version of the blockchain

What is the difference between a softfork and a hardfork?
- A hard fork is caused by an update that expands the rule set that determines the eligibility of a block to be included in the network. A soft from minimizes the rule set as to making some blocks already in the network invalid.
What are some of the reasons why you would do a hardfork?
- Hardforks provide a more democratic selection process and clearer distinction between the previous and updated chains
What are some of the risks with performing a hardfork?
- Hardforks may split the blockchain, leading to fewer nodes within the that network, decrease in hash power and therefore security in the network

- Soft forks are preferred as they are backwards compatible and offer software upgrades but don’t affect the network. They are possible when the majority of users choose to upgrade to the new version. A hard fork is a change to the protocol that makes the old and new incompatible and users running the old version will be completely separated. All users need to switch to the new version to be able to continue validating and verifying transactions and you end up with 2 different chains with differing protocols.
- Developers would do a hard fork if they want to add features, correct security issues or reverse transactions if say there was a hack that needed to be reversed.
- Double spending on new blocks and controversial forks are risks that could disrupt security and endanger the network.

- What is the difference between a softfork and a hardfork?
A hard fork update expands the rule set such that previously invalid blocks become valid whereas soft forks contract the rule set and blocks previously valid become invalid.
- What are some of the reasons why you would do a hardfork?
Developers may implement a hard fork in order to correct important security risks found in older versions of the software, or to add new functionality.
- What are some of the risks with performing a hardfork?
Hard forks may result in “double spending” : coins spent in a new block can be spent once again in an old block as merchants and users with the old version of the software will not see the spending registered on a new chain. It is also an unstable time for the cryptocurrency potentially resulting in volatility.

What is the difference between a softfork and a hardfork?
Softforks They are planned mass updates (not accidental) to contract the consensus rules that make previously valid blocks invalid. If less than 50% of hash power will lead to a fork.
Hardforks are planned mass updates (not accidental) to expand the consensus rules. They make previously invalid blocks valid.
What are some of the reasons why you would do a hardfork?
Update to the consensus rules to expand them, e.g increase MB of block.
What are some of the risks with performing a hardfork?
Splits chain, community, and hash power.
If 100 % of the network to update does not occur two different blockchains with two communities will exist moving forward.

- What is the difference between a softfork and a hardfork?
[Ans] hard-fork is the case that makes a previously invalid block as valid with change of consensus rule, however in case of soft-fork a previous valid blocks becomes invalid. Hard-fork are usually for case with rule expansion while soft-fork happens for rule contraction. Hardfork updates are not backward compatible while soft fork are backward compatible and a preferred one. - What are some of the reasons why you would do a hardfork?
[Ans] To create new currencyand at times to improve the performance. - What are some of the risks with performing a hardfork?
[Ans] It splits the chain and also the community

Soft fork is usually constricting the ruleset for valid transactions and blocks - for example, reducing block size. It makes previously valid blocks invalid in at least one ruleset.
-
Hard forks can happen due to ideas being accepted by some and not by others in the community (community includes everyone from those who transact, mine, run nodes etc) and one side deciding on the change to go ahead which will expand the ruleset of valid transaction blocks. This could be due to block size acceptance, or to have a decision made by the community.
-
Splitting the community, hash rate being split quite substantially causing security vulnerabilities in one side, possible double spends as both sides may not see txs on each others side.

Hard fork makes blocks that were invalid before valid by for example relaxing some of the protocols rule (increase block size). Soft fork makes blocks that were valid before invalid, by for example tightening some of the protocol rules (reduce block size)

Update to the consensus protocol

If both fork has support the community is divided and so it’s the hashpower, reducing network security

A hard fork can split the community and the blockchain- splitting hash power reduces security temporarily

- What is the difference between a softfork and a hardfork?
Hardfork: Makes previously invalidated blocks valid– expansion of the ruleset.
Softfork: Update that makes previously valid blocks invalid – shrinking the ruleset .
- What are some of the reasons why you would do a hardfork?
- If the chain wants to split because it cant get the majority of nodes to agree to an update.
- If the community wants to make a new blockchain, taking the chain in a different direction and make a new currency like Bitcoin Cash.
- What are some of the risks with performing a hardfork?
- Splits the community
- Loss of hash power also means a less secure network.
