Segwit Reading Assignment

[LuisDePablo]

1. What was a proposed alternative to Segwit? Increase block size from 1MB to 2 MB
2. What did Segwit solve more than just the scaling issue? The TX malleability problem: if Alce sends 1 BTC to Bob with sign “abc”, Bob could change the TX but only the sign to “def” so Alice would not be able to find the TX while it actually happened.
3. How is Segwit and the Lightning network connected? Segwit made it possible for the lightning network to be developed on top of BTC.
4. Are people, wallets and other services forced to use Segwit? Nope

[Zaan]

1. As an Alternative to Segwit was to enlarge the block size limit.
2. It stoped the transaction malleability by removing the signature from tx block.
3. Segwit supports the development of second layer protocols like lightning network, which boost btc transaction capacity by taking frequent small transactions off-chain and settling on etc blockchain when the users are ready
4. No , since its a software, however the adaptability rate is growing and that d be the only way to progress further

@cosmicbuc

ready for what–I’m unsure. Again, if someone can elaborate a bit more on this, it would really help my understanding

The Lightning network only requires 2 transactions on the main chain, one to open a channel and one to close the channel. Once the channel is open you can have unlimited number of transactions with basically no fee and only settling the difference between the channels on back to the main chain once they are closed.
You can learn more in detail how the Lightning network works in our Lightning network course.

1. To raise the MB to a higher number, so more transactions can run through.
2. The Tx ID issue by placing the sig outside the block thus removing the opportunity to alter the sig.
3. Lightning network is building on top of the SEGWIT to smoothen the network allowing second layer protocols to be built.
4. Old adresses can also be used–> softfork.

[Ole_Zwarts]

1. to increase the blocksize
2. it also solved the issue of TX malibility
3. Segwit makes the second layer possible
4. no

• What was a proposed alternative to SegWit?

The alternative to SegWit was to increase the block size (a hardfork) which did happen and created Bitcoin Cash.

• What did SegWit solve more than just the scaling issue?

The SegWit protocol solved the issue of the transaction malleability. This flaw allowed anyone to change small details that modified the transaction id (and the subsequent hash) but not the content.

• 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. The lightning network wants to boost transaction capacity by taking Sam transactions off chain and settling them on chain at a later date. Lightning network creates payment channels between two nodes.

• Are people, wallets and other services forced to use SegWit?

No, because it is a soft fork protocol.

[magicnum3er1]

1. What was a proposed alternative to Segwit?
   Increasing the block size. That’s how we got the BTC cash

2. What did Segwit solve more than just the scaling issue?
   The malleability fix which removes the signatures from the tx data.

3. How is Segwit and the Lightning network connected?
   Lightning network is the protocol ‘build on top’ of the btc blockchain.
   Segwit allowed some tx to be processed of chain.

4. Are people, wallets and other services forced to use Segwit?
   It was done with the softfork so No

[aperes]

1. Simply increasing block size
2. Solved the scaling issue while retaining the security (no mallability)
3. Segwit solved the malleability problem which enabled Lightning network to be developed.
4. No

[George21]

1. To increase the size of the blocks.

2. It solved the issue of transaction malleability.

3. It 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. No it was a soft fork.

[drala.lungta]

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

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

3. How is Segwit and the Lightning network connected?
   Segwit enabled second layer protocols such as the lighting network.

4. Are people, wallets and other services forced to use Segwit?
   No but segwit adoption is increasing slowly.

[Adzio]

1. Increasing block size.
2. It fixed malleability problem - oportunity to make a small change in signature that couses tx id to change. It was a way to convince sender that his transaction wasnt valid/confirmed.
3. Fixing malleability problem allows to create Lightning network. This network is fast transactions, based on “transfer tunnel” and multisignature wallet. Bob can make such a tunnel with Kris and send funds back and forth offchain. When transactions are finished they will go to blockchain network and become part of it.
4. No, but it looks resonable to use it - it fixes problems.

[shonesto]

1. What was a proposed alternative to Segwit?
   Increasing the clock size to 4MB
2. What did Segwit solve more than just the scaling issue?
   It also solved malleability
3. How is Segwit and the Lightning network connected? it is what made lightning network possible
4. Are people, wallets and other services forced to use Segwit? No but it is being added to wallets

[Kevko]

1. What was a proposed alternative to Segwit?
   Increasing the maximum block size to for example 2MB

2. What did Segwit solve more than just the scaling issue?
   Having the first created transaction id deleted so the initial transaction id could not be tracked anymore

3. How is Segwit and the Lightning network connected?
   Segwit made second layer solutions (lightning network) possible

4. Are people, wallets and other services forced to use Segwit?
   No, this update was a soft fork update

[gcradduck]

1. What was a proposed alternative to Segwit?

One proposed alternative was to increase the block size so as to allow more transactions per block, instead of addressing signature data.

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

Segwit also addressed the malleability of signature data such that attempts to modify unconfirmed signature data could not result in a new transaction id.

3. How is Segwit and the Lightning network connected?

Segwit’s approach to the malleability issue provided greater security and integrity in the context of unconfirmed transactions, making second layer projects more feasible.

4. Are people, wallets and other services forced to use Segwit?
   Segwit represents a softfork, meaning participants are not forced into its use and may continue on the same blockchain while adhering to the previous rules of the network.

[jenell]

1. What was a proposed alternative to Segwit? Increasing the block size limit - such as 1MB to 2MB

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

3. How is Segwit and the Lightning network connected? Segwit made possible the development of 2nd layer protocols like the lightening network. The lightening network is a solution to help solve the problem of transaction speed on the blockchain network by introducing off-ledger transactions.

4. Are people, wallets and other services forced to use Segwit? - No they are not forced to use Segwit. More wallets are implementing it though.

[RGehl]

What was a proposed alternative to Segwit?

To increase block size

What did Segwit solve more than just the scaling issue?

It also solved transaction malleability because people can not make slight changes to the signature as the signature is stored somewhere else.

How is Segwit and the Lightning network connected?

Segwit supports second layer protocol like lightning network.

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

It is optional and is a soft fork

[travmc]

1. Increase in block size, Which is what Bitcoin Cash did with their fork.
2. Solved the malleability issue and took out the signatures that cold be altered.
3. Segwit supports second layer solutions like the lightning network.
4. Nobody is forced to use Segwit (Segregated witness)

[Suat_S]

1. Increasing the block size was proposed as an alternative.

2. Also solved the transaction malleability bug.

3. SegWit made the network more secure and this led to the development of second layer protocols like Lightning Network.

4. No, it is a soft fork.

[jschlier]

1. Increasing the size of the block.

2. It solved the transaction malleability by removing the signature out of the transaction.

3. Segwit makes the lightning network far more secure and relaiable.

4. No.

[Devin.Crypto]

1. What was a proposed alternative to Segwit?

Increase the block size from 1 MB to 2 MB.
