Bitcoin Sidechain Privacy

This post is part of my bitcoin privacy post!
My long promised sidechain privacy for bitcoin is here!
So you might be wondering what in the world is a sidechain?
Worry not that what I am here for! 😊
So a sidechain is a separate chain that connects with the main chain. The main chain currency acts like the currency on the sidechain. This introduces new tech to the coin without affecting the mainchain. Plus all transaction on a sidechain don't clog up the main chain so it good scalability solution as well 😊
Sidechain is being worked on bitcoin to help exchanges scale and introduce bitcoin to the Dapps's arm race!

However privacy side chains can be built as well!

The most well known bitcoin privacy chain is MimbleWimble.

MimbleWimble:

MimbleWimble uses a type of Confidential Transactions and Coinjoin.

In Mimblewimble, the receiver of a transaction generates the blinding factor which is used to prove ownership of the bitcoins. And the way it does this by "excess value", which is the difference between the inputs and outputs. This excess value is a set of random numbers that ensure that only the person who generated the blinding factor (the receiver) can spend the bitcoins. So, the blinding factors do not add up to zero anymore, but rather to another amount that is like a private key.
This is Mimblewimble version of Confidential Transactions.

Now to hide individual transactions, Mimblewimble uses a type of Coinjoin!
Instead of containing transactions, Mimblewimble blocks will only have a list of new inputs, a list of new outputs and a list of signatures which are created from the aforementioned excess value.

Mimblewimble is a scalable solution.

If it were to be active on Bitcoin since day one, the blockchain would be somewhat bigger (a few GB) than it is now. Compared to other real privacy coin this is amazing accomplishment.

MimbleWimble is natively private.

There are no ring signatures or zero-knowledge proofs on top of a transparent bitcoin-like transaction. In a MimbleWimble transaction, all values are fully obscured. There are no reusable or identifiable addresses. Every transaction looks the same to an outside party. Unlike the popular cryptocurrency, where the exact history of all transfers is publicly verifiable, that will not necessarily be the case for Mimblewimble. Private keys are no longer in play at all. (Nor are public keys or addresses. 😊)
So right now in theory MimbleWimble is better than Monero privacy in fact it so good Monero might be using a MimbleWimble sidechain themsleves.

This is the main privacy chain but in theory clones of Monero and zcash sidechain can be made for bitcoin but that boring and not that great :(

Hope you liked it guys! Cited my sources too but cheetah going to complain either way :(
I going to combine this all in one post to avoid confusion.
This is my end to my bitcoin privacy series.

See ya :)
Now time for my game and Dapps battle series
