1: A hard fork makes previously invalid blocks valid, while a soft fork makes previously valid blocks invalid.

2: If you wanted to expand the consensus in some or multiple ways.

3: A hard fork can split the community and hashing power, reducing security.

1- A hardfork is an expansion and a softfork is a contraction.
2- If the current rule set is too small for the consensus need in you use case.
3- Running a risk on security with two seperate yet the same chains.

  1. Hardfork = expanding the rules, Softfork = tightening the rules
  2. To change the consenus, it’s clear and “democratic”
  3. Splitting the chain so also the community and the hashpower

1.What is the difference between a soft fork and a hard fork?
1.A. A Hard Fork update includes blocks that where not valid previously and now are valid by the rule set change and is expansionary in nature. A Soft Fork does the opposite and with an update makes previously valid blocks invalid and is contractionary in nature.

2.What are some of the reasons why you would do a hard fork?
2.A. Split the into two chains and take control, force/make 100% change or choose democratic update, to avoid an update, implement a rule change, fundamental security failure.

3.What are some of the risks with performing a hard fork?
3.A. Other chain doing a 51% attack, decrease security and hash power, splitting community.

  1. A softfork is created by an update making a previously valid block invalid. A hardfork is created by an update making previously invalid block valid.

  2. Change in consensus rules; e.g. newly allowing blocks up to 2mb rather than 1mb.

  3. Splits the community and chain while also reducing hash power.

1.) A soft fork makes previously valid blocks invalid and doesn’t result in a chain split if > 50% of the network’s hash power adopts the new rules. Conversely, a hard fork makes previously invalid blocks valid & requires 100% of network nodes to adopt the update to avoid a chain split, making a split inevitable. One way to visualize the difference is in terms of expanding the validation requirements so that more blocks are considered valid (hard fork) or contracting validation requirements so that less blocks are considered valid (soft fork).

2.) Developers might propose a hard fork if they want to push out a new update that does not fit within the current consensus rules.

3.) The biggest risk of performing a hard fork is splitting hash power and compromising network security as a result. Hard forks also tend to split the community, as some people prefer the old set of rules and others prefer the new ones.

  1. A softfork is a contraction of existing rule set making previously valid blocks invalid.
    A hardfork is an expansion of existing rule set making previously invalid blocks valid.

  2. Hardfork is done to create a separate chain where a subset of the community can create a rule set that they like-- not consistent with the rule set of the existing chain.

  3. When hardfork is done, hashpower is split and thus reduced for the 2 new chains. Reduced hashpower means reduced security.

  1. What is the difference between a softfork and a hardfork?
    The diferente is when you have a hardfork you have an expansion of the rule set witch makes a previous invalid block to become valid. A soft fork you have a contraction of the rule set witch makes a previou valid block to become invalid.
  2. What are some of the reasons why you would do a hardfork?
    Some of the reasons are that the hard fork is more clear and democratic update
  3. What are some of the risks with performing a hardfork?
    The risks are: split the chain, split the community and split the hash power

  1. A Soft Fork updated makes previously valid blocks invalid, which means that can work inside the current set of rules. and a Hard Fork makes previously invalid blocks valid, this means that don’t work with the current set of rules.
  2. To make a change in consensus rules.
  3. That it will split the community and the chain in 2 ways, this will make the hash power split and makes it less secure.

1.A Soft Fork update makes the previously valid block invalid.
2. A hard fork is a change to the bitcoin protocol that loosens the ruleset enforced by full nodes that update to enforce the hard fork rules. An example could be to increase the block size from 1MB to 2MB, 2MB which was valid previously is now a valid block.
3.It will split the chain in 2 ways, which will create less hash power that results in security mattes

  1. Soft fork is when the updates are a contraction of the consensus rules and makes previous valid blocks invalid. Hard fork is when the updates are a expansion of the rules and makes the previous invalid blocks valid.

  2. Its clear and democratic. Expandi g the rules.

  3. It splits the community, the chain and the hashpower (security)

  1. Soft fork is for the for updates on same chain, it do not split chains and improves performance, hard fork splits chain (new members are added to the Community) , therefore hash rate power decrease the nodes that does not updates stay with the og chain (Community is split). But still I think both of them are important for network to keep updating.

  2. If there are some issue with the og chain or it get slow for some reason you can introduce a hard fork for solving the issue of the network.

  3. The risk involved are Community gets split, if hash power get reduced, then the Security of the chain also get reduced and it slow down the progress of the project.

1.A hard fork expands the rule set while a soft fork contracts the rule set in mining.

2.A hard for would be done to create a new currency, have a clear update based on new needs.

3.The risks are you will be splitting the hash power of the network, splitting the community and splitting the chain.

  1. Soft works makes valid block invalid and hard forks make invalid blocks valid.

  2. Update the protocol to specialize its use and functionality. To change its consensus.

  3. Security is at risk, chain may be split and therefore the hashpower and the community will be split.

What is the difference between a softfork and a hardfork?

A hardfork update makes previous invalid blocks valid and a softfork update makes previous valid blocks invalid. A hard fork splits the chain whereas a soft work doesn’t.

What are some of the reasons why you would do a hardfork?

You want to increase the block size or do another update that expands the number of blocks that would be valid.

What are some of the risks with performing a hardfork?

Less hash power can mean lower security.

  1. A Soft Fork happens when an update makes previously VALID blocks, INVALID. A Hard Fork happens when an update makes previously INVALID blocks, VALID.
  2. A Hard Fork is seen as a clear update, therefore, we may call it “Democratic”.
  3. There may be a split chain, a split in the community and, a hash power split which may result in reduction of security.

  1. What is the difference between a softfork and a hardfork?
  • HardForks makes previously invalid blocks vaild which is an expansion of the rule set.
  • Soft Fork makes previously valid blocks invalid which is a contraction of the rule set.
  1. What are some of the reasons why you would do a hardfork?
  • The rule set is clear and not ambiguous
  • It is settled in a democratic way
  1. What are some of the risks with performing a hardfork?
  • This results in a split chain
  • It also splits the community
  • Hash power split, making it not as secure

    1. What is the difference between a softfork and a hardfork? In order for the network to avoid a hard fork, 100% of it must be updated with this new set of “rules” that validate previously invalid blocks. If only a certain percentage of the network (nodes) update, a hard fork is created, as two sets of consensus rules are governing two chains now. There is an expansion of the rules in a hard fork. What is a soft fork? A soft fork will mean that previously valid blocks will now become invalid. As opposed to a hard fork, where a whole new chain is formed, a soft fork works as an “update’ because it is backwards compatible – the nodes simply update their consensus so that new blocks can be appended. There is a contraction of rules in a soft fork.
    1. What are some of the reasons why you would do a hardfork? to form a new cryptocurrency, expand consensus rules, denote a clear change in consensus
    1. What are some of the risks with performing a hardfork? split up a community, split the chain
