#3414
  1. to increase the mB size of the block
  2. it put an end to transaction malleability and allowed for more transactions within a block without increasing the size of the block
  3. segwit allowed for layered protocols to exist by eliminating the transaction malleability like, lightning network
  4. no, there are still several people and wallets who have not accepted segwit

  1. A proposed alternative to SegWit was to increase the block size to 2MB which would also lead to a hardfork, Bitcoin Cash.
  2. SegWit fixed a bug in the bitcoin code called transaction malleability, lowered fees along with supporting a second layer solution.
  3. SegWit supports the second layer solution which is where the lightning network runs.
  4. No, it is a soft fork, however, wallets are adding SegWit support.

  1. Increase the block size.
  2. SegWit fixed transaction malleability by removing the signature information and storing it outside the base transaction block.
  3. SegWit supports the development of possible second layer protocols that is on the Lightning network.
  4. No, it is still compatible with the old protocol. (SoftFork)

What was a proposed alternative to Segwit? --> To increase the block size.
What did Segwit solve more than just the scaling issue? --> Also Trx Malleability
How is Segwit and the Lightning network connected? --> With Segwit, you can enable Layer 2 features eg: Lightning network as you do not need to relying on unconfirmed Trxs became less risky
Are people, wallets and other services forced to use Segwit? --> No. It is a soft fork.

1. What was a proposed alternative to Segwit?
Increasing the blocksize to >1MB. This would lead to a hard fork like Bitcoin Cash

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.

3. How is Segwit and the Lightning network connected?
SegWit Made made the development of second layer protocols pissible, such as the lightning network.

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

  2. It solved transaction malleability.

  3. Helped achieve second layer protocols

  4. No its a choice because its a soft fork.

  1. An alternative to SegWit was proposed, which involved increasing the block size, which led to a hard fork, Bitcoin Cash.

  2. SegWit also allowed the development of the lightning network, which makes unconfirmed transactions safer.

  3. SegWit;s malleability fix allowed the development of the lightning network.

  4. SegWit is not mandatory, as it was a soft fork.

A proposed alternative was to increase the blocksize.

Segwit decreased the tx size by removing the signature. The signature took up a lot of space. Also, it stopped solved the malleability issue.

Segwit and the Lightning network are connected by Sigwit solving the malleabilty issue and the Lightning network will take small tx off the block until the user is ready.

No, it’s a soft fork.

  1. What was a proposed alternative to Segwit?

A block size increase, but this would result into the same problem in the future.

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

It solved the fact that txid can be exploited, but now with the signature removed of the block, you cannot change the signature and therefore you cannot change the txid.

  1. How is Segwit and the Lightning network connected?

Segwit supports the developement of second layer protocols such as Lightning network.

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

No because Segwit is a softfork.

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

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

Segwit solved the scaling issue, as well as the issue of transaction malleability

3. How is Segwit and the Lightning network connected?

Segwit makes the second layer possible

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

No, as it is a soft fork update, wallets and other service can still use the old protocol.

1.The proposed alternative to Segwit was to raise the block size to increase the speed and
scalability to the blockchain.
2.Segwit solved the scaling issue by removing the signature from transactions so that more transactions can fit into a block and storing the signatures separately.
3.Segwit allows for second layer protocols to be added to blockchain such as the Lighting network.
4.Segwit is not being forced on anyone but more companies and wallets are making the change.

  1. What was a proposed alternative to Segwit?
    increasing block size beyonf the 1MB limit

  2. What did Segwit solve more than just the scaling issue?
    It also solved the issue of malleability which was a bug that would have resulted in future security problems if bitcoin was to scale

  3. How is Segwit and the Lightning network connected?
    Segwit made it possible to run second layer solutions like the Lightning network

  4. Are people, wallets and other services forced to use Segwit?
    No, but using segwit leads to lower transaction fees

  1. The alternative to SegWit ist Bitcoin Cash(BCH) where not the structure of the block tx is changes but the maximum block size is doubled to 2MB instead of one.

  2. Besides the block size problem SegWit fixed the mellability bug. You cant cheat anymore by changing the signature.

3.SegWit Supports the development of second layer protocols. By fixing the mellability bug every feature based of uncorfirmed tx is safer and easier to develop.

  1. As far as I understood : everyone who uses btc is using Segwit as long as your wallet has the necessary update. The alternative would be BCH. So if I am correct you are kind of forced to use it but by looking at the pros and cons I don’t get why people wouldn’t want it.

As a user you can still make old style txs on Bitcoin just fine. :slight_smile:

  1. What was a proposed alternative to Segwit?

The initial solution was to increase the sizes of blocks from 1MB to 2MB. However, the developers concluded that this would’ve been a repeated issue, having to increase block sizes once in a while. This also would’ve led to Bitcoin being more centralized because miners would require more demanding hardware and software and not every miner can afford this.

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

Segwit also solved the issue with transaction malleability. Before the Segwit soft fork, anyone could change the signature in their block, which would also change the hash of the block. By making the signature and the transaction block two separate entities, the hash of the transaction could not be tampered with, thus limiting malicious activities on the network.

  1. How is Segwit and the Lightning network connected?

The Segwit update enabled the Lightening network to exist. This second layer protocol increased Bitcoin’s transaction block capacity by taking some transactions off-chain.

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

No, in fact as of 2018, only 14% of transactions on the Bitcoin network were using the Segwit protocol. Furthermore, as is the nature of forks, users are not obligated to follow any new protocols and can move a new chain in a different direction, as Bitcoin Cash did from Bitcoin.

  1. Increase size of blocks to allow for more transactions but this has other inefficiencies.
  2. Transaction malleability, changing a transaction after it happens
  3. The malleability fix made any feature that relied on unconfirmed transactions less risky and easier to design. This allowed for second layer protocols like lightning network
  4. No because it avoided the need for a soft fork.

  1. An alternative to Segwit could’ve been increased block size.
  2. Segwit solved Transaction Malleability by removing the witness/signature data from the actual TX.
  3. Segwit supports the implementation of second layer protocols, such as the Lightning network.
  4. People, wallets and other services are not forced to use Segwit. Native bitcoin is still supported as this was just a soft fork.
