Segwit Reading Assignment

Blockchain and Bitcoin 101

  1. An increase of the block size through a hard fork.

  2. It solved the transaction malleability issue where someone could change small aspects of the signature. This change would then affect the transaction id which is a hash of the transaction data.

  3. Segwit supports 2nd layer protocols like the lightning network which is also a solution to the Bitcoin scaling issue. The lightning network provides fast transactions off-chain and is meant for small transactions. The Segwit malleability fix reduces the risk of unconfirmed transactions on this 2nd layer.

  4. No because it was a soft fork the old rules still applied.

  1. What was a proposed alternative to Segwit? To only increaase the blocksize, which would need to be done again in the future as that size is eventually too small.
  2. What did Segwit solve more than just the scaling issue? malleability, signatures are no longer part of the tx so the hashes will not change by changing the sig.
  3. How is Segwit and the Lightning network connected? The LN is a 2nd layer solution using segwit.
  4. Are people, wallets and other services forced to use Segwit? No they are not.

  1. What was a proposed alternative to Segwit? Bitcoin cash chose to increase block size to 4mB.
  2. What did Segwit solve more than just the scaling issue? Removing signatures meant processing more transactions without changing block size.
  3. How is Segwit and the Lightning network connected? Through second layer of protocols.
  4. Are people, wallets and other services forced to use Segwit?No, but as more wallets embraced the upgrade, the segment of transactions that uses Segwit will increase .

1. What was a proposed alternative to Segwit?

Increasing the maximum block size to 2 megabytes

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

Transaction malleability

3. How is Segwit and the Lightning network connected?

SegWit supports the development of second layer protocols, such as the lightning network. The malleability fix made any feature that relied on unconfirmed transactions less risky and easier to design.

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

Not everyone in the bitcoin community agrees that SegWit is the solution bitcoin has been waiting for. Some believe that it is a case of “kicking the can down the road,” and at best a temporary fix.

Resistance to SegWit was one of the factors behind the development of 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.

Hello,

  1. the proposed alternative to segwit is increasing block size, as has been done with bcash.

  2. Segwit solved the problem of transaction malleability, meaning an actor could modify the signature of a transaction after it was broadcast, creating a completely different hash.

  3. Removing the transaction malleability vulnerability allows for greater certainty of broadcast but not confirmed transactions, making second layer easier to implement.

  4. No, it is a soft fork.

Best,

  1. Extending block size (BTC Cash hard fork)
  2. Transaction malleability
  3. lightning network will further boost bitcoin’s transaction capacity by taking frequent, small transactions off-chain, only settling on the bitcoin blockchain when the users are ready
  4. No because it is a backward-compatible soft-fork

  1. a hard fork to increase block size.

  2. it fixed transaction malleability.

  3. The Lightning network needed a fix to transaction malleability which Segwti provided.

  4. No Segwit is backwards compatible.

  1. to increase the block size.
  2. the transaction malleability, the possibility that someone was able to change the signature after the transaction was sent.
  3. segwit solves the signature problem
  4. no, it is a softfork update, original blocks that include the witness data still are accepted to the blockchain.

    1. Increasing the block size to 2MB. Network participants who took this route formed a hard fork named Bitcoin Cash.
    1. The security issue of transaction malleability. By storing the signatures separately to the Tx, any alteration to the signature would not affect the hash on the blockchain.
    1. Segwit enables 2nd layer applications.
    1. No one is forced to use Segwit, it is a soft fork the network has been slow to adopt it and there are still nodes that do not use it.

  1. Increase block size (B Cash)

  2. By keeping the signatures separate, anyone attempting to chain the signature does not affect the tx I’d, as the signature is not in the block, it does not affect the hash.

  3. Lightening network is a second layer solution which is only possible because of segwit.

  4. No, as segwit is a soft fork. But more and more are updating and adopting.

  1. To increase the block size to support more transaction which would have been a temporary solution.

  2. It solved the transaction malleability issue.

  3. Segwit supports second layer solutions such as lighting network by making any feature that relied on unconfirmed transactions less risky and easier to design. Lighting network will take small transactions off chain until ready to put on chain.

  4. No, it is a soft fork.

  1. Increasing block size (what Bitcoin Cash did).

  2. It solved the transaction malleability issue.

  3. The adoption of Segwit allows better development of second layer solutions such as the Lightning network, as it makes features that rely on unconfirmed transactions less risky and easier to design.

  4. No they are not, anyone can use the former protocol. Furthermore, Segwit is backwards compatible. Currently, at the time of writing (January 2020), Segwit’s adoption is around 50%.

  1. To increase the block size.

  2. It solves tx malleability problem.

  3. SegWit supports the develpment of secnf layer protocals, such as lightning network.

  4. There are not forced, althoug there high incentives in adopting SEGWIT as decrease the fees.

  1. Increasing capacity of block to 2mB
  2. It solves transactio malleability that may drive to scams
  3. It allows more tx per second and lower fees
  4. No, but it becomes more and more popular so fx wallets without this function can be pushed out of the market

  1. Alternative proposal to SegWit was increasing the block size to 2 MB.
  2. Segwit apart of solving scaling issue, also solved the malleability issue, that allowed changing transaction ID by changing a signature of a transaction.
  3. By reducing risk of malleability, Segwit boosted development of lighting network. The malleability fix made any feature that relied on unconfirmed transactions less risky and easier to design.
  4. Network participants are not forced to use Segwit, it is voluntary.

  • What was a proposed alternative to Segwit?
    • Increase the block size.
  • What did Segwit solve more than just the scaling issue?
    • The TX malleability issue, where the TXID could be changed.
  • How is Segwit and the Lightning network connected?
    • Lightning network is a second layer protocol which builds on Segwit. Both together can make millions of transactions per sec instead of 7 to 10 per sec on older network with a low risk of unconfirmed transactions.
    • Lightning is protocol that runs with (is a layer over) Segwit.
  • Are people, wallets and other services forced to use Segwit?
    • No, it is a soft fork. But once adaptability becomes high enough (!95%), it will be the only way to remain on the BTC network without forking.
