You could have a peek at other answers :wink: Segwit made 2nd layer solutions safer and easier to design.

#3636

My Answers:

  1. Introducing a larger block size limit to the protocol, resulting in a hard fork.
  2. Transaction Malleability, an attack that lets someone change a BTC transactions unique ID before confirmation on the network. As well as supporting second layer protocols and smart contracts.
  3. The Lighting network is a second layer protocol in BTC which was maybe possible to implement because of Segwit.
  4. No, due to the fact it was a soft fork protocol upgrade. Allowing all nodes on the network to still communicate with each other, no matter if they have the updated protocol or not.

  1. The proposed alternative was to increase the overall block size like with bitcoin cash.

  2. Segwit solved the transaction malleability problem as well as making transactions smaller.

  3. Segwit solving the transaction malleability problem allowed the lightning network to build a system that can finally utilize unconfirmed transactions in a more secure way.

  4. No, the update resulted in a soft fork so segwit is optional .

1.Increasing of block size (from 1 MB to 2 MB or more).
2.Solving transaction ID malleability by removing the signature in the transaction block.
3.Segwit enables the Lightening network.
4.No, because Segwit is a soft fork.

  1. Increase a block size to 2 mB
  2. It solved vulnerability to attack by changing transaction hash by manipulating signature which was in the transaction data.
  3. Segwit supports second layer solution such as lightning network.
  4. No.

  1. What was a proposed alternative to Segwit?
    Proposed alternative to Segwit was to increase the block size but it has its own issues like increasing the cost of mining removing the smaller miners from the competition and causing decentralisation. It was also not reasonable as increasing block size raise other issues like propagation of block over the network, more storage and limit the network growth once more people join the network.

  2. What did Segwit solve more than just the scaling issue?
    It also solve the issue of transection malleability. Removing the signature from transection details decrease the size of block and also protect the transection id from attacks.

  3. How is Segwit and the Lightning network connected?
    SegWit supports the development of second layer protocols, that give birth to lightning network.

  4. Are people, wallets and other services forced to use Segwit?
    No one was forced to use the Segwit, as it was soft fork and all old version works perfect with this change.

  1. increasing the blocksize which leads to a hard fork
  2. by solving the issue of tx mall. more complex features such as second layer protocols and smart contracts are partly possible.
  3. segwit made lightning network possible
  4. no, since it is a soft fork. wallets are supporting segwit.

  1. What was a proposed alternative to Segwit?
    Increasing the block size. (For example from 1mB to 2mB). However that would not solve the problem, because at the rate at which demand for the size grown, it would reach 2mB sooner or later anyway and we would face the sambe problem.

  2. What did Segwit solve more than just the scaling issue?
    It solved the issue Transaction Malleabillity. By taking signature out of the transaction details people were no longer able to change the signature in incoming transactions.

  3. How is Segwit and the Lightning network connected?
    By fixing Transaction Malleabillity, Segwit allowed second layer sollutions such as Lightning networt to bloom.

  4. Are people, wallets and other services forced to use Segwit?
    No they are not, as it was the soft fork.

Ah ok, thank you Alko!

1.The proposed alternative was to increase the block size from 1MB-2MB
2. Segwit also solved the transaction malleability problem
3. Segwit supports the development of the lightning network as a layer 2 protocol, where small4. transactions can be taken off-chain
4. People are not forced to use Segwit but are incentivised because of its promise of lower fees and faster confirmations.

  1. Hard fork to double the transaction size limit from one mB to two mB
  2. Transaction malleability
  3. Segwit allowed the development of lightning network
  4. No, people, wallets, and nodes are adopting at their own rate because the transaction block size remained at 1Mb with segwit

Make the block full

Fix the malleability problem that anyone can change and that the exchange id can be altered.

SegWit upholds the improvement of second layer conventions, like Lightning organization.

NO

  1. Increasing the block size to 2 mB

  2. It made it so that people are not able to change the signature of an imput and change the hash.

  3. Segwit allows for layer 2 protocals and light the lightning network and smart contracts.

  4. No, they can use Bitcoin Cash or another alternatives

  1. The proposed alternative was to fix a bug in the bitcoin code (transaction malleability).
  2. SegWit is temporary fix. It allowed more TX within a block (reduced fees), without increasing block size or Hard fork, supports development of 2nd layer protocols.
  3. SeWIt and Lightning are connected through SegWits support of layer protocols and enables the security of such.
  4. No, however many have and it will reach a point where it would be silly not to include segWit.

  1. The alternate to Segwit was to increase the Blocksize to 2MB, which happened with the creation of Bitcoin Cash.
  2. Segwit also solved a bug in bitcoin’s code called transaction malleability. This flaw allowed anyone to change small details (signature) that modified unconfirmed transactions and therefore changing their hash value.
  3. Segwit allowed second layer protocol like the lightning network (off-chain transactions)
  4. No, because Segwit was a soft fork.

Increase the block. But for a temporary solution.

Misuse of the manufacturability of the exchanges.

Lightning organization required an exchange malleably fix in layer 1 of the blockchain, like SegWit.

No
