  1. What was a proposed alternative to Segwit?
    The initial proposed alternative to Segwit was to increase the bitcoin block size from 1MB to 2MB.

  2. What did Segwit solve more than just the scaling issue?
    Segwit solved the transaction malleability problem. By removing the transaction signature information from the TDIX, it would no longer be possible to easily change the transaction data by just changing the signature information.

  3. How is Segwit and the Lightning network connected?
    Segwit supports the development of Lightning network.

  4. Are people, wallets and other services forced to use Segwit?
    No one is forced to use Segwit but users will adopt it based on their judgement of its value.

  1. What was a proposed alternative to Segwit?
  • To increase the allowed block size to >1mB
  1. What did Segwit solve more than just the scaling issue?
  • Transaction Malleability – Prevents other users from changing the transaction hash. Digital Signature is now placed outside the transactions block
  1. How is Segwit and the Lightning network connected?
  • Segwit made second layer coding on top of bitcoin network possible by removing the digital signature out of the block.
  1. Are people, wallets and other services forced to use Segwit?
  • No, however exchanges and wallets have been implementing it. A hard fork was created the other proposal of increasing block size to >1mb and it is called bitcoin cash.

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

  2. What did Segwit solve more than just the scaling issue?
    Segwit solves transaction malleability that allows easier deployment of the lightening network with lower fees.

  3. How is Segwit and the Lightning network connected?
    Segwit facilitates the functioning of the lightning network.

  4. Are people, wallets and other services forced to use Segwit?
    No, old addresses and transactions can still be used due to a soft fork.

  1. Bitcoin Cash - solution increasing the block-size
  2. Malleability issue was solve simultaneously by removing signatures from data hashed. It’s kept outside, separately.
  3. Lightning is a solution based on primary layer thanks to eliminating the malleability issue by Segwit
  4. They’re not forced but it’s highly in their interest to embed it.

  1. What was a proposed alternative to Segwit?
    The fork that became bitcoin cash by increasing block size

  2. What did Segwit solve more than just the scaling issue?
    It also added security since the signatures could no longer be altered since they are kept outside the block

  3. How is Segwit and the Lightning network connected?
    Solved the malleability issue

  4. Are people, wallets and other services forced to use Segwit?
    No but they are encouraged because it could make fees lower and the blockchain more secure

  1. Make block size bigger, e.g. Bitcoin Cash.

  2. Solves malleability issue and reduces the fees.

  3. Supports second layer solution e.g. lightening network.

  4. No. Wallets are however adding segwit support.

  1. What was a proposed alternative to Segwit?
    increasing block size
  2. What did Segwit solve more than just the scaling issue?
    it removed issue of transaction malleability
  3. How is Segwit and the Lightning network connected?
    By removing transaction malleability issue Segwit made development of layer 2 solutions like lightning network possible. Lightning network delays confirmation of small transactions to increase scalability, unconfirmed transactions would have been at much higher risk should transaction malleability still be possible.
  4. Are people, wallets and other services forced to use Segwit?
    no, adoption is voluntary (soft fork)

  1. Just increase block size to 2mB
  2. It solved the malleability issue as well
  3. The lightning network is built on a layer on top of the bitcoin blockchain and is made possible because of the fixing of the malleability issue
  4. No because it was a soft fork …

  1. What was a proposed alternative to Segwit?

Increase block size from 1MB to 2MB

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

It fixed transaction malleability, because signatures in a segwit tx
are not included in the tx hash

  1. How is Segwit and the Lightning network connected?

By removing signatures from tx data scrips can be implemented to work with second layer protocols, like lightning network

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

Not necessarily, old wallets and nodes still work, so segwit is a soft fork.

1.What was a proposed alternative to Segwit?
The alternative was increasing the blocksize, so that more transaction would fit in each block. That would have caused a hard fork and actually happened with the start of bitcoin cash.

2.What did Segwit solve more than just the scaling issue?
By stripping down the SegWit from the block, the soft fork solved a problem in the network called malleability, where the transaction id could be modified.

3.How is Segwit and the Lightning network connected?
Beside the malleability issue fixed, the blocks become smaller/slender, therefore the btc blockchain could now be the base of second layer protocols such as Lightning Network. Lightning will speed up the process of tx and does not rely on the data that signs every tx which is stripped apart from the blocks through the protocol update.

4.Are people, wallets and other services forced to use Segwit?
No, it´s a soft fork and he old protocol ist still valid.

  1. What was a proposed alternative to Segwit?

    -to increase block size

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

    -Transaction malleability. It removes the transaction signature and stores it outside the base transaction block, thus allowing signatures and scripts to be changed without affecting the transaction ID.

  3. How is Segwit and the Lightning network connected?

    -SegWit supports the development of second layer protocols, such as the lightning network. The lightning network also boosts transaction capacity, it takes 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, they are not forced, but Segwit reduces fees and makes transactions faster, which is good for people, wallets and other services

  1. What was a proposed alternative to Segwit?
    Increasing the block size

  2. What did Segwit solve more than just the scaling issue?
    It also solve the malleability issue, which allow “bad” people to modify the signature and so the ID of the transaction.

  3. How is Segwit and the Lightning network connected?
    Lightning network is a second layer protocol, second layer protocol are made possible only thanks to Segwit.

  4. Are people, wallets and other services forced to use Segwit?
    No

  1. What was a proposed alternative to Segwit?
    To increase the blocksize by making a hard fork. but when only from 1MB to 2 MB it seems to still carry a limitation.

  2. What did Segwit solve more than just the scaling issue?
    By holding the signature information separately from the content of the transfer, SegWit also made it possible to keep signatures more hidden while still operating on the content, thus solving the malleability problem.

  3. How is Segwit and the Lightning network connected?
    The Lightning network uses Multisig for setting up private payment channels between few parties aside from the blockchain ledger. This introduces a risk which is, for small transfers at least, almost eliminated by using also SegWit.

  4. Are people, wallets, and other services forced to use Segwit?
    No, since Segwit is a soft fork they can still use the old protocol but chose to use Segwit as needed.

  1. What was a proposed alternative to Segwit?
    Increasing the block size of 1MB to a higher block size

  2. What did Segwit solve more than just the scaling issue?
    It also solves the transaction malleability, which was a bug in bitcoin that could allow someone to change the signature in a transaction and thus also change the transaction ID. Solving this issue also supports the development of layer 2 solution.

  3. How is Segwit and the Lightning network connected?
    Solving the transaction malleability increased the support for the development of layer 2 solutions such as the lightning network. Features relying on unconfirmed transactions become less risky and are now easier to design

  4. Are people, wallets and other services forced to use Segwit?
    No, segwit is a soft fork. Adoption of Segwit upgrade is increasing.

    Segwit solved the transaction malleability issue as well
