1. What was a proposed alternative to Segwit?
The proposed alternative to Segwit was to make the block size limit greater than 1mB which resulted in a hardfork called bitcoin cash. In this fork of the bitcoin network it chose to implement a larger block size limit rather than rely on a new transaction structure.
2. What did Segwit solve more than just the scaling issue?
Without the signature information Txs weigh much less. This means that more Txs can fit in a block. BTC can then process a greater throughput without changing the block size.
3. How is Segwit and the Lightning network connected?
Segwit supports development of second layer protocols, which Lightning network is one of. Segwit’s malleability fix made Lightning network possible because it is a second layer solution that relied on unconfirmed transactions.
4. Are people, wallets and other services forced to use Segwit?
In short the answer is no. Segwit was a soft fork which was completely voluntary; however, today more and more are adopting it because of its value to the network and users.

1.Increasing the block size as in BCH.
2. Segwit also solved tx malleability issues by removing signatures from the block thus allowing for smart contracts and layer 2.0 solutions.
3. Segwit added security to unconfirmed tx and allows for lighting network to resolve some tx off-chain. This is turn allows for faster validation of tx and blocks when the network is handling more volume.
4. It was a soft fork which does not force users to comply, however, there are many benefits and the update is gaining adoption.

- Blocksize increase, but it was not a good idea because in time the blocksize had to increase more
- Tx ID malleability and lower fees along with supported a second layer solution
- Segwit helped for making lightning network possible
- No its a soft fork and all previous rules are already there

- Simply to increase the block size
- The Segwit solved the scalability problem by removing the signature out of txn block, thus making it a lot smaller so that you can fit in a block more and at the same time, the malleability bug was fixed since the signature is stored outside the txn block and does not change the tnx ID while being edited.
- The Segwit implementation has enabled the ability to integrate the second layer solution and smart contracts on the blockchain.
- No, they are not forced but since it made the network more secure, faster, and scalable more people are joining the update.

1.- A bigger block size
2.- The maleability issue (actually the main goal of SegWit)
3.- By puting apart the signature, it enables the use of the lightning network and other second layer solutions.
4.- No,they are not, it is optional and currently its adoption is growing.

1. What was a proposed alternative to Segwit?
Increasing block size which would have led to a hard fork.
2. What did Segwit solve more than just the scaling issue?
The transaction malleability issue which allowed changing transaction Id after it was sent.
3. How is Segwit and the Lightning network connected?
SegWit supports the development of second layer protocols. The malleability fix improved security for operations with unconfirmed transactions. Lightning network would take some frequent and small transactions off-chain, to settle them on the actual blockchain once users are ready, thus, boost bitcoin’s network productivity.
4. Are people, wallets and other services forced to use Segwit?
As a soft fork, it is not mandatory.

- Increase block size but that would have just postponed the problem and implied a hard fork
- transaction malleability
- It’s a layer 2 solution to Bitcoin enabled by the Lightning network
- not all nodes have updated

1 - It’s been proposed to increase the block size from 1MB to 2 MB.
2 - It also solved the problem of the Transaction malleability.
3 - SegWit supports the development of second layers protocols. One of this is the Lightning network which boosts the bitcoin’s transaction capacity by taking frequent small transactions off-chain and only settling on the bitcoin blockchain when the users are ready.
4 - Within the bitcoin blockchain SegWit has been fully adopted but the resistance in using it has lead to the development of bitcoin cash, a fork which implemented a larger block size limit.

To increase the block size to two mB.
Now if signature is changed it doesn’t effect the original transaction hash.
Segwit helps with layer 2support
No it doesn’t.

Increase in block size to 2mB (Bitcoin cash fork) -
What did Segwit solve more than just the scaling issue?
SegWit fixed transaction malleability by removing the signature information (otherwise known as the “witness” information) and storing it outside the base transaction block. -
How is Segwit and the Lightning network connected?
A big step forward made possible by SegWit is that 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. -

Alternative to Segwit was to increase the block size but this idea would lead to the same problem after a cetrain period of time. Increasing block size was never an option.
-
Segwit solved transaction maleability problem by removing the digital singatures out of transactions block and added 4 MB layers to base transactions extending to add more security and other layer of applications.
-
Lighting network can be added to the second layer that is introduced by segwit.
-
No. Community can still work with original transactions as it is a soft fork. There are companies adding SegWit support to their wallets.

In any case you can still use old style txs on Bitcoin just fine.

Opposition to SegWit led to developers offering an alternative upgrade which increased the block size to 2MB. Developers initiated a hard fork resulting in Bitcoin Cash, which chose to implement a larger block size and avoid adopting the new transaction structure of SegWit.

SegWit solved the issue of transaction malleability. Transaction malleability allows anyone to alter the signatures which results in a modified transaction ID after a transaction has been sent. SegWit fixed this issue by removing signature information and storing it outside the base transaction block. This also allowed for the development of second layer protocols such as: lightning network (boost transaction capacity by enabling numerous transactions outside the main blockchain until the payment channels are closed and then recorded as a single transaction on the blockchain); MAST (enables more complex bitcoin smart contracts); Schnorr signatures (enables transaction capacity boost) and TumbleBit (anonymous top-layer network).
-
The lightning network adds another layer to the bitcoin blockchain and enables users to create payment channels between any two parties on that extra layer. Channels can exist as long as required and because they’re between two people, transactions will be almost instant and fees will be extremely low or non-existent. Numerous transactions can take place off-chain, and once the channel is closed, information about the initial and final balance is broadcasted to the bitcoin blockchain and recorded as a single transaction. The lightning network is a way to increase the transaction capacity of bitcoin.

People, wallets and other services are not forced to use SegWit - the SegWit upgrade is still compatible with the previous protocol and as such avoids a hardfork (although a hardfork was initiated in response to SegWit which resulted in bitcoin cash). The initial uptake of the SegWit upgrade was very slow but as more wallets upgrade, the percentage of transactions that use the SegWit structure will increase and bitcoin fees should decrease as blocks contain more transactions.

Increase the capacity of the blocks.

Eliminating the possibility of altering the hash of a transaction when modifying the signature. By saving the signature outside the transaction, the hash of the transaction would not be modified by altering the signature.

Al Segwit solving the problem of malleability made possible the implementation of a 2nd layer, which would allow transactions to be carried out in a faster and safer way.

No, because is a softfork.
