Video is a medium that is included in several media that can be used for learning. A lot of someones experience about bitcoin is also shared via video and we can use it as an effort to increase knowledge. When a student needs a teacher to make it easy to understand something, the video will be very helpful when practicing directly without ignoring other learning media.
If too much reading can make us bored and difficult to understand something, then video is another alternative that we can use to learn and improve skills and knowledge when we are still in a difficult situation related to Covid-19 and is something that is recommended and I agree with OP.
Agree, videos are mostly very demonstration-friendly. Research has shown that 83% of human learning takes place visually, especially for an audience with a short attention span. And videos, helps me a lot in efficiently learning a technical and complicated topic like Bitcoin.
Segwit - (1) Segregated Witness is a method of scaling the Bitcoin network to confirm more transactions on each block (2) without increasing the block size itself. It is invented in order (3) to shrink the file size of a bitcoin transaction. Every Bitcoin transaction has three parts: sender, recipient, digital signature. The signature is considered to be "the witness" for the transaction. Segwit means that we are (4) separating the witness from the base transaction in order to make it (3) smaller in size. This allows more transaction to be approved each time a block of transactions have been confirmed.
i'm surprised that after 3 years people are still confused about SegWit and make mistakes about what it does!
you made 4 mistakes here.
(1) SegWit is not a scaling solution, it was mainly a malleability fix that also helped with scaling by increasing the capacity. it also paves the way for second layer solutions (for scaling) such as LN.
(2) SegWit did increase the block size, of course we no longer use "size" but "weight" instead but the raw byte size of a block is increased for example nowadays blocks grow as big as 1.2 MB with a record of 2.1 MB and they can grow to a little less than 4 MB
(3) neither block size nor transaction sizes were decreased. in fact in some cases they grow to bigger sizes when you use SegWit due to its overhead. the reason why more transactions can fit in a block is because capacity is increased using 4 MB weight.
(4) signature is not "separated" from transactions. it is still a part of it, but now it is placed near the end of it before the locktime instead of inside txin's sigscript.
Thanks for this, appreciate this one and it really helps me a lot too! So much articles about Segwit! Will fix this mistakes!
1. Segwit fixes transaction malleability that also helped with scaling by increasing the capacity.
2. Segwit blocks are restricted by weight. The raw byte size of a block is increased, though Legacy nodes will still receive blocks that are 1,000,000 bytes or lower due to stripped witness data.
3. More transactions can fit in a block because capacity is increased using 4 MB weight
4. scriptSig data is not separated but it is moved to the end of the transaction.
Thaks for reading the thread all the way through!
