Segwit Reading Assignment

Blockchain and Bitcoin 101

You can still make old style transactions on Bitcoin just fine so the user is not forced to use it. :slight_smile:

Segwit assignment

1- the other option was increasing the block size limit. This led to the creation of a hard fork and the origin of the BTC cash blockchain.
2- It solved also, actually the update was meant to solve this being the size block issus solving a positive side effect, the malleability of the transactions. The possibility of tampering the signature of the transactions making the original Tx desappear of the mempool.
3- THe lightning network is a second layer protocol built on top of the main BTC blockchain which allows to get the most frequent and smaller Txs off the main chain making the general chain more agile and faster.
4- If they want to stay in the BTC blockchain, yes they are forced to use it.

  1. The development of Bitcoin cash. A larger block size limit (Hard fork).

  2. Transaction malleability. A bug in the bitcoin code.

  3. Segwit protocol upgrade supports the development of Light network, which is a second layer Protocol.

  4. No. It is kind of like a Soft fork.

  1. Increased block/tnx size
  2. Solves the signature malleability
  3. It allows smaller transactions to be taken off chain until the users are ready for it to be added to the block .
  4. No. They will get segwit tnx’s but do not have to update their protcol and will still add the blocks.

  1. To increase the block size from 1MB to 2MB and would result in a hard fork.

  2. It also removed the tx malleability and made it possible to have lighter nodes that do not store the signatures.

  3. SegWit made it possible to design secure second-layer applications.

  4. No, it is a soft fork, so it is still valid with the old protocol.

  1. TO increase the block size only.
  2. Transaction Malleability.
  3. The introduction of Segwit allowed the use of second layer protooals like lightening.
  4. Not forced as the block didnt change, over time more people took on the segwit to move with the developments.

  1. What was a proposed alternative to Segwit?
    Increasing the block size which is how Bitcoin Cash was created.

  2. What did Segwit solve more than just the scaling issue?
    Transaction Malleability issue and lowers fees.

  3. How is Segwit and the Lightning network connected?
    Segwit helped make the lightening network and second layer solutions possible

  4. Are people, wallets and other services forced to use Segwit?
    No it was a soft fork so not everyone is forced to use it and old addresses c an still be used.

  1. What was a proposed alternative to Segwit? - To increase the block size

  2. What did Segwit solve more than just the scaling issue? - SegWit fixed transaction malleability by removing the signature information

  3. How is Segwit and the Lightning network connected? - By supporting the development of second layer protocols

  4. Are people, wallets and other services forced to use Segwit? - Short answer is “NO” at the time of the article. I have looked around and looks like even now it is not forced.

  1. To increase size of blocks to 2 MB
  2. Segwit also solved the issue with transactions malleability, secured network and allow Bitcoin to process transactions quicker due to the fact that transactions weight is less without signatures.
  3. Segwit supported the development of second layer protocols such as lightening network. By fixing transactions malleability Segwit made unconfirmed transactions less risky. The lightening network helps boost Bitcoin transactions by taking small transactions off the chain, until users will be ready to process bigger transactions, than it will attach it to the Bitcoin blockchain.
  4. No, wallets and another services can still use the old protocol. Many big names among wallets use Segwit already, but it’s only their choice.

  1. Increase block size

  2. Kept block size at 1MB and solved TX malleability by removing signature data from the block. Signatures can be changed without changing the TX data. Increases security.

  3. SegWit made second layer protocols possible

  4. No it’s a soft fork.

  • How is Segwit and the Lightning network connected?
    Segwig makes second layer possible

  1. increasing block size but this was seen as a temporary fix only.
  2. Transaction malleability, it also helped increase network/ transaction security.
  3. Second layer protocols were made possible such as lightning network which provides faster transaction times.
  4. No as older nodes that don’t implement segwit are still active on the network and its a soft fork so still compatible with the previous protocol.

To increase block size

  1. What did Segwit solve more than just the scaling issue?

Segwit also solved transaction malleability - the problem being able to change the hash of tx after it has been sent.

  1. How is Segwit and the Lightning network connected?

Segwit made second layer solutions possible.

  1. Are people, wallets and other services forced to use Segwit?

Not at all. This was a ‘soft-fork’, so people’s old addresses and transactions can still be utilized.

  1. To increase the Block Size (Bitcoin Cash)
  2. The allowance of implementing second layer protocols, such as smart contracts and the lightning network
    Decreasing transaction fees per transaction
    Fixed the transaction malleability issue
  3. SegWit supports the development of second layer protocols, such as the lightning network
  4. No since it’s a soft fork. Therefore, the non updated nodes find every block in the updated network valid

  1. By going from a 1mb block to a 2 mb block.

  2. Lowering transaction fees, and people cant change the tx id anymore.

  3. Segwit supports the second layer solution, which is the lightning network.

  4. No

What was a proposed alternative to Segwit? -  Increasing block size to be able to append more transaction by removing the need for signatures. Transaction ID was adequate because it can't be altered. Also, 
What did Segwit solve more than just the scaling issue? - Segwit fixes the bug issue of transaction malleability by removing the need for user input signature repeatedly. 
How is Segwit and the Lightning network connected? The lightning network boost transaction capacity by taking frequent, small off-chain and only then append when users are ready.
Are people, wallets and other services forced to use Segwit? - not force but some big names have implemented Segwit while others such as Coinbase is working on it.

  1. What was a proposed alternative to Segwit?
    Bitcoin cash, a fork of the bitcoin network which chose to implement a larger block size limit rather than rely on a new transaction structure.
  2. What did Segwit solve more than just the scaling issue?
    SegWit fixed transaction malleability by removing the signature information and storing it outside the base transaction block. With that, signatures and scripts can be changed without affecting the transaction id.
  3. How are Segwit and the Lightning network connected?
    Segwit supported the development of the lightning network a second layer protocol increasing bitcoin’s transaction capacity by taking frequent, small transactions off-chain, only settling on the bitcoin blockchain when the users are ready.
  4. Are people, wallets, and other services forced to use Segwit?
    No.

  1. An alternative to SegWit is block size increase. Bitcoin Cash is an example of implementation of larger block size.

  2. SegWit solved security issue in Bitcoin called “transaction malleability” when signature of transaction can be changed and therefore block hash will be different from the original.

  3. SegWit removed malleability issue and made possible development of second layer protocols such as Lightning network.

  4. No, SegWit is a soft fork and people, wallets and other services can start adopting it gradually.
