#4216

  1. What was a proposed alternative to Segwit?
    Increase the block size from 1mB to 2mB.

  2. What did Segwit solve more than just the scaling issue?
    It fixed the block malleability problem.

  3. How is Segwit and the Lightning network connected?
    Segwit made it less risky and easier to design features like lightning network. This will also increase the number of transactions per second in the future.

  4. Are people, wallets and other services forced to use Segwit?
    No, because it is a soft fork. The deployment is ongoing.

  1. To increase size of the block from 1 MB to 2 MB
  2. It help increase more transactions in each block and reduce fees, it also fixed the malleability problem so no one can change small details.
  3. It provides a second layer solution
  4. No

  1. What was a proposed alternative to Segwit?
    Doubling the block size limit from 1 mB to 2.

  2. What did Segwit solve more than just the scaling issue?
    By stripping signature data out of the block, Segwit also solved the malleability issue, in which a TX could be modified after confirmation by tweaking the signature, resulting in fraudulent TX’s to unsavy users.

  3. How is Segwit and the Lightning network connected?
    Segwit’s removal of the signature from the block data is what allowed the Lightning network to be implemented.

  4. Are people, wallets and other services forced to use Segwit?
    No. Segwit is only in use during mining (transaction confirmation).

What was a proposed alternative to Segwit?
=> Increase the block size

What did Segwit solve more than just the scaling issue?
=> it also solved the problem with transaction malleability

How is Segwit and the Lightning network connected?
=> Lightning network relies on unconfirmed transactions. By removing the signature data from the transaction data, SegWit made the features that relies on unconfirmed transactions safer and easier to design.

Are people, wallets and other services forced to use Segwit?
=> No. As a Soft Fork update, it is optional.

Homework - segwit

What was a proposed alternative to Segwit?
Increasing the block size from 1mb to 2 mb’s, which would result in a hard fork.

What did Segwit solve more than just the scaling issue?
Security for malleability in the signatures.

How is Segwit and the Lightning network connected?
Because segwit removed the malleability susceptions they could get connected with lightning payments.

Are people, wallets and other services forced to use Segwit
Segwit was a soft fork so it shouldn’t make any problems if you update or not.

What was a proposed alternative to Segwit?

Changing the block size to 4MB instead of 1MB.

What did Segwit solve more than just the scaling issue?

SegWit activation also boosted development work on other features such as MAST and solves transaction malleability.

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.

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

No.

  1. What was a proposed alternative to Segwit?
    A proposed alternative to Segwit was to increase the block size, however developers felt they needed a more permanent solution as this was seen as a temporary fix.

  2. What did Segwit solve more than just the scaling issue?
    Besides the scaling issue another issue Segwit addressed was transaction malleability which made the network more secure, as before it was vulnerable to possible hacks and currency theft.

  3. How is Segwit and the Lightning network connected?
    The advancement of Segwit allowed for the development of second layer protocols, which the Lightning network is built on.

  4. Are people, wallets and other services forced to use Segwit?
    No, it was a soft fork. However, as the upgrade continues to be embraced adoption will continue to increase.

  1. What was a proposed alternative to Segwit?
    A hard fork increasing bitcoins block size from 1mb to 2mb

  2. What did Segwit solve more than just the scaling issue?
    It also solved the transaction malleability issue. By removing the private signatures from the blocks editing the transaction information is impossible.

  3. How is Segwit and the Lightning network connected?
    segwit made layer 2 solutions possible like MAST for example.

  4. Are people, wallets and other services forced to use Segwit?
    No, segwit was a softfork, currently right now about 40% of bitcoin transactions use segwit, but its increasing more and more every year.

  1. The one’s who didn’t want to follow the new transaction structure, but were focused on increasing the block size introduced a hard fork and created Bitcoin Cash.

  2. Segwit solved the problem related to Transaction Malleability.

  3. Segwit supports 2nd-layer solutions (lighting network) - operations based on unconfirmed transactions (e.g. smart contracts) were made possible and less risky = micropayments, off-chain enabled.

  4. No, Segwit was a soft work - therefore no need for 100% adoption. Nevertheless, great opportunity since less sat/byte.

1/ a hard fork by increasing block size from1 to 2mb.
2/transaction malleability- where some was able to make small changes to the trx id which would change the hash. The recipient was then able to say no transaction received .
3/Segwit allowed for scaling layer 2 solutions due to faster and larger transactions.
4/ People, wallets and other services are not forced to use Segwit because it is still compatible with old protocol however some hardware wallets have built in segwit ie ledger

  1. A increased block size.

  2. Besides the scaling issue Segwit resolved the TXN malleability problem.

  3. By solving the malleability problem, which Segwit did, it enabled the development of Layer 2 solutions on BTC network, such as :zap: network, MAST, Schnorr signatures, and Tumblebit.

  4. No one is forced to do anything in regards to BTC. It’s voluntary participation. If someone doesn’t want to accept the change in development and improvement of BTC network, they can take a hike or switch to another network - BCASH, BGOLD, etc.

  1. What was a proposed alternative to Segwit?
    Increasing block size, which is what Bitcoin Cash did to create a fork.

  2. What did Segwit solve more than just the scaling issue?
    It stopped transaction malleability so signatures would not have an affect of transaction malleabilty.

  3. How is Segwit and the Lightning network connected?
    Segwit allowed layer 2 protocols to be developed. Lightning network was introduced allowing frequent small transactions.

  4. Are people, wallets and other services forced to use Segwit?
    No, there are still plenty people not using Segwit. But, more and more people continue to embrace it.
