Segwit Reading Assignment

[Coco]

1. To increase the block size
2. Tx malleability, which means being able to change the transaction hash of a transaction after the transaction has been sent
3. Segwit is connected to lightning network because it supports the development of second layer protocols, such as lightning network.
4. No, because it is a soft fork

[bithomie]

1. Blocksize increase which led to hard fork BCH
2. BTC smart contract capability, anonymity of top-layer network
3. Segwit introduction makes 2nd layer solutions like lightning network possible, its a pre-requisite for it to be established.
4. No it is a soft fork no forcing

1. increasing block size

4. no, it is a soft fork

[CryptoEagle]

What was a proposed alternative to Segwit?
The proposed alternative to Segwit was to increase block size, which took the form of bitcoin cash.

What did SegWit solve more than just the scaling issue?
SegWit ended up solving more than just the scaling issue by reducing block size so that more throughput could occur and by developing a second layer protocol which reduced the risk of unconfirmed transactions. Additional benefits also included MAST, Schnorr Signatures, and TumbleBit.

How is Segwit and the Lightning network connected?
SegWit enables a second layer protocol to be coded on the bitcoin blockchain; the lightening network is a second layer protocol; therefore, the lightening network is a second layer protocol enabled by SegWit.

Are people, wallets and other services forced to use SegWit?
Technically, people are not forced to use SegWit, but practically, they are. As the blockchain and associated applications adopt SegWit more and more user services will directly or indirectly require SegWit to function.

[Cashflow101]

1. The alternative proposed to Segwit was to increase the size of the block

2. Segwit prevented transaction mallability and makes a transaction size smaller

3. and it support development of a second layer protocols

4. No, but exchanges and wallets are slowly adding Segwit to their platforms or wallets

[Marc-C]

1. What was a proposed alternative to Segwit? Increase he block size - ex. bitcoin cash
2. What did Segwit solve more than just the scaling issue? support second layer contracts like lightning network and smart contract support
3. How is Segwit and the Lightning network connected? segwit allowed the second layer for the lightning network
4. Are people, wallets and other services forced to use Segwit? no it would be a soft fork

[Douma]

1. Alternative to segwit is proposition of increasing block size limit.
2. It solves transaction malleability in which transactions ID´s can be changed but segwit update solved the problem by removing signatures from transaction data, still signatures can be changed but it don´t effect transaction id .
3. Segwit further supports development of second layer solutions such as lighting network in which smaller transaction can be taken off-chain. Malleability fix made any feature of reliable on unconfirmed transaction less risky and easier to build on.
4. No it all depends on their will because is a soft fork.

[alex.stahmer]

1. Increasing the size of a block to 2MB

2. Malleability issue. Changing the signature of a txn and therefore changing the hash. This could have led to fraud in transactions and prevented bitcoin blockchain from more complex transactions, such as smart contracts

3. Segwit made the Lightning network possible, since it fixed the malleability issue (I honestly don’t know what the Lightning network is at this point of the academy)

4. No, they don’t. But it would have limited their services to their customers.

[Tor]

1. What was a proposed alternative to Segwit?
   Answer: Increase blocksize
2. What did Segwit solve more than just the scaling issue?
   Answer: Get rid of malleability of transaction Id
3. How is Segwit and the Lightning network connected?
   Answer: 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.
4. Are people, wallets and other services forced to use Segwit?
   Answer: No, there is a migration towards intergration, but it takes time to adopt

[GoHackYourself9]

1 bitcoin cash
2 keeping block size to 1mB by removing the signature thus more secure for malleability issues
3 a seconde layer of protocol with small transactions off-chain
4 no, but adoption came gradually

[Mal]

1. Increase the block size. This caused a hard fork, resulting in Bitcoin Cash.
2. Dealt with transaction malleability, which allowed people to alter transaction ID.
3. Segwit supported the development of second order applications like the Lightning network.
4. No

[HexagonalView]

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

2. What did Segwit solve more than just the scaling issue?
It solved the issue of transaction malleability.

3. How is Segwit and the Lightning network connected?
With SegWit, the Bitcoin network is supporting the development of a second layer protocol, such as lighting network.

4. Are people, wallets and other services forced to use Segwit?
There is no force imposed to update, since Segwit is considered a soft fork.

[Belle3]

1. What was a proposed alternative to Segwit?
   The proposed alternative to Segwit is to increase block size limit.

2. What did Segwit solve more than just the scaling issue?
   Transaction malleability by removing the signature from the actual hash that is the transaction ID.

3. How is Segwit and the Lightning network connected?
   Segwit supports a second layer which enables the lightning network.

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

[uP_CadeiraMan]

1. It was an increase in block size limit which lead to the bitcoin cash fork.

2. Segwit fixed the transaction malleability bug.

3. Segwit facilitated the development of second layer protocol such as the lightning network which relied on the unconfirmed transactions.

4. No, it was a soft fork update.

[DigiCoin]

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

What did Segwit solve more than just the scaling issue?
-it resolved transaction malleability,due too put transaction ID’s outside the block.

How is Segwit and the Lightning network connected?
-With a second layer protocol

Are people, wallets and other services forced to use Segwit?
-No,there are forks of the network that use another structure.

[Rob_McCourt]

1. One of the fixes was to increase the block limit from 1mb to 2mb

2. It solved the Tx Malleability and decrease size of Txs

3.The big step forward for Segwit was that it supported development of layer protocols like Lightning Network, The Malleability solved the risk of unconfirmed transactions and easier to design.

4. People arent forced but the fees will come down when more people use the alternative wallets.

Any more input is welcome folks. thanks. Enjoyed this section but still not up to scratch with multiple Inputs and Outputs and re hashing the signatures etc.

Thanks.

[Hamburgler]

1. What was a proposed alternative to Segwit?
   To increase the block size allowing more information into each block.

2. What did Segwit solve more than just the scaling issue?
   it helped enable more complex bitcoin smart contracts. Also an uptick in both usage and additional functionality experimentation like the lighting network.

3. How is Segwit and the Lightning network connected?
   They are similar in the sense that they are separated (Signature & tx / bitcoins mainnet and lighting network) allowing for more transactions. Segwit lead to the lighting network creating second layer protocols.

4. Are people, wallets and other services forced to use Segwit?
   No because it still falls under the old protocol (soft fork)

[Fati]

1. Increase in block size, Bitcoin cash
2. Malleability, second layer protocols.
3. By solving malleability it lead to second layer protocols like lighting network.
4. Not forced but many wallets are supporting Segwit update.

[vandenBosch]

1. Increasing the blocksize

2. Transaction ID malleability. Lower fees as more transactions are possible in a block

3. Segwit made second layer protocol possible on witch the lightning network is build

4. No, its a softfork. Transactions are still possible withinnthe rules set

[Shawn1]

1. it is an block size increase
   2.transactoin ID malleability witch in turn allows aesier deployment of lightning the network
   3.segwit helped make lightning network possibel
   4.no it was an soft fork. though cosidering they read segwit transactions as cliamable by anyone old transactions can be used as well,some fields are only emty
