Segwit Reading Assignment

Blockchain and Bitcoin 101
#4276
  1. Increasing the size of a block
  2. Security issue by removing signature from transaction’s hash => changing signature no longer provided any benefit to malicious users
  3. The Lightning uses small transactions and the Segwit update allows for much smaller txs.
  4. No

  1. Increasing the block size from 1mb to 2mb was proposed as an alternative.

  2. Besides from the scaling issue, Segwit solved tx malleability.

  3. Segwit supports the adaption of lightning networks.

  4. people aren’t forced to use it, as the update caused a soft fork.

  1. What was a proposed alternative to Segwit?
    • Increase the block size, which was really just a temporary solution.
  2. What did Segwit solve more than just the scaling issue?
    • It also solved the transaction malleability issue since the signature is now stored outside of the transaction, no longer allowing for the transaction ID to be modified.
  3. How is Segwit and the Lightning network connected?
    • Since Segwit solved the Transaction Malleability issue it led to the enabling of the Lightning Network, which is a network of micropayments
  4. Are people, wallets and other services forced to use Segwit?
    • Negative, Segwit is a soft fork and has not been fully adopted

  1. An alternative to SegWit was Bitcoin Cash that was a fork in the network to implement larger block sizes.

  2. SegWit solved more than just the scaling issue by also solving transaction malleability to stop transaction IDs being changed.

  3. SegWit allows for more development of layer 2 solutions to help Bitcoin scale with the lightning network.

  4. They are not forced to use SegWit, but some are taking a while to make the upgrade to implement it.

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

  2. What did Segwit solve more than just the scaling issue?
    Fixing the transaction ID malleability, which also allowed the development of other layer protocols such as the Lightning Network.

  3. How is Segwit and the Lightning network connected?
    Segwit can support the Lightning Network after the correction of the Tx malleability.

  4. Are people, wallets and other services forced to use Segwit?
    It is a soft fork, not a hard fork, so no. And adoption grew consistently.

  1. increasing blocksize,

  2. transaction malleability.

  3. segwit fixing tx malleability made the lighting network safer and easier to develop on.

  4. people are forced into participating in the chain since its a soft fork, but they could still choose if they want their transaction to be in the segwit style or not.

  1. What was a proposed alternative to Segwit?
    The proposed alternatives to segwit would be to increase the block size so more transactions could fit.

  2. What did Segwit solve more than just the scaling issue?
    Segwit increased the number of transactions within each block without tampering with the data or hash for each block. Segwit also prevented a hardfork creating a whole new chain of transactions when the bitcoin code would be updated. The layer two potential is also something that will keep the longevity of the original code the same. I personally think without the use of layer two alternatives bitcoin will have no choice but to hardfork and increase the block size when global adoption happens. At that point, states and professional miners will take on the heavy load of mining and keeping up with the speed of transactions. That would ultimately cause more centralization, which is not what bitcoin is about. Hopefully, we can stay as close to the original code as possible. More memory would definitely be needed in the future. Micro nodes would be a major contributor for the bitcoin network. If the bitcoin network could copy the Divi Project’s one click master node protocol, it would tremendously help the network. People would be able to run a micro node off their phone all over the world. This would also keep BTC as decentralized as possible.

  3. How is Segwit and the Lightning network connected?
    The Lightning network is written in the same type of code as bitcoin. The bitcoin maxi’s claim that Litecoin has no value, but why would they test Segwit on the Lightning network if it wasn’t important or valuable? The Lightning network will allow bitcoin to keep being built upon while keeping the same integrity to the network.

  4. Are people, wallets and other services forced to use Segwit?
    No, there is a choice on people using Segwit or not.

  1. What was a proposed alternative to Segwit?

A: Increasing the block size limit from 1MB to a greater value.

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

A: Transaction Malleability

  1. How is Segwit and the Lightning network connected?

A: Segwit and the Lightning Network are connected by the innovation and implementation of the Segwit solution, allowing the Lightning Network to be developed without risk of malleability. Separating the signature function from the base transaction block allowed producing a second layer protocol with features relying on unconfirmed transactions less risky and easier to design.

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

A: At present yes it is fully implemented. It was a soft fork so it was not instantaneously adopted by every node.

  1. What was a proposed alternative to Segwit?
    An increase of the block size.
  2. What did Segwit solve more than just the scaling issue?
    It also resolved transation malleability making the network more secure, Signature information was removed from the base transaction blocks.
  3. How is Segwit and the Lightning network connected?
    Lightning network is a second layer (L2) protocol, built on top of Bitcoin. The development of layer 2s was made possible as a result of Segwit.
  4. Are people, wallets and other services forced to use Segwit?
    No, it’s a soft fork, old addresses can still be used.

A proposed alternative to SegWit was to increase the block size, which would have been a hard fork (ex: bitcoin cash).

2. What did SegWit solve more than just the scaling issue?
SegWit solved the transaction malleability problem (by removing the signature / witness info from the block).

What was a proposed alternative to Segwit?
Increasing the block size from its 1MB limit.

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. With that, signatures and scripts can be changed without affecting the transaction id.

How is Segwit and the Lightning network connected?
The lightning network will further boost bitcoin’s transaction capacity by taking frequent, small transactions off-chain, only settling on the bitcoin blockchain when the users are ready.

Are people, wallets and other services forced to use Segwit?
No, people are not currently forced to use Segwit.
