Bitcoin Conditions: CheckigFromtom (BiP 348)

This is the second article in a A row Delete target to reach individual contract recommendations that have reached mature point eliminating the deep breast.

No sure, CSS) with Brandon Black and Jeremy Rubin by Bip 348, is contracted. As I have said in the start article to this series, they do not cover the conditions, but co-operate or within them in some way. CSFS is the first instance of that.

The OPCOS CSFES is very simple, but before going through as it goes through as it works that we will work on the basic scripts in fact how a Bitcoin script works indeed.

Script is a steady language based language. That means that “stacks” data are together on the top of each other on the stack, and run back, returning the data or prosperion from the data.

There are two parts of script when executed and determined, the “witness” is given to solve script, and have the script. The witness / scripting is the script “to add a” on the left of the lock script, and then all elements are added to (or working on this example (or “|“Identifying the limit between the evidence and script):

1 2 | Air_add 3 on_feth

An example script contribute to the “1” value to the stack, then the value “2” according to that. OP_add brings the two elements of the stack and put them together, putting the product back to the stack “3”). “3” has added to the stack. The last thing, Of_all, gives the two best things of the stack and returns “1 and 1 represent the stac (1 and 1).

Script must expire with the last thing on top of the stack, otherwise the script (and trade is invalid.

This is this fundamental example of the Pay-to-Push-to-PubUby Script (P2pkh), ICT to a legacy that starts with a legacy that starts with a legacy that begins with “1”:

| Dup hash160 Cookies equality

First signature and the public key will be added to the stack. Then the best stac is called a dup and doubled, return to the top of the stack. Hash160 makes the best stack stack (public public key), oak, and then returning it to the top of the stack. The public key from the script has been placed on top of the stack. Activities decide the same as equality, it captures the two upper stack items and returns 1 or 0) based on the outcome. The same intervenexious difference also is running out after equality, which fails to the item's High Stac 1, and removes the best stac. Eventually there are cooks run, which grasping the best two assume that they are signed and PubUbyE, determined the signal against the transaction. If it is valid he is sending 1 on top of the stack.

As CSFS works

The cook is one of the preferred OPCODes in Bitcoin. All businesses, with almost all these businesses to this concerter will have some point in one of his scripts. Signature confirmation is a fundamental proportion of the Bitcoin Protocol. The problem is, it is not almost gone about what the message you are examining the signature. The Cooba Bon will only be able to verify the signature of the signature against the matter. There is some flexibility, ie you can decide with freedom rate which parts the signature relates, but that.

CSFS aims to change this by allowing any signature of any irregular message against any irregular message, instead of being limited to the matter of the matter. Opcode follows very basic operating structure:

| CSFS

The signature and the message is dropped on top of the stack, then capturing three best-to-stage three objects of the stage to base the message. If the signature is valid, 1 has been placed on the stack.

That's it. Very simple ranges the query allowing users to specify irregular messages instead of just the existing exchange.

What is CSFS useful for

So what is this good? What is the signature of the signature against the stack of the stack in place?

Initially, along with CTV will be able to provide action by something which electronic developers want bleeding, signatures that may connect to a variety of matters. This was first commended as a new Sigrah flag for signatures (the area that says to the parts of the business that is signed by). This was needed as a trade signature covers the transaction ID of the business they created the result. This means that no signature is not available for a spending that detail product.

This is a wishing to do for lightning for lightning because it allows us to make a channel penalty away with channel paintings. Every electronic electronic statements are made for a punishment of a punishment and punish trade to ensure that your channel does not use any of them. If they try you can apply to their money. Advanced action would just allow you to just prove the current State transaction to one to stop the attempt to stop.

This can be achieved by a basic script that will carry out a CTV and signature over a survey with CSFS. This would allow no favor with the CSFS key to create any product that is created by this script.

Another useful feature of UTXO is. In the same way as the CtV Hask signings that are submitted validly with a script into the bottom of the survey, such as a new public key. Allows a script that allows a CSFS key to none Public key, which may be determined by CSFS and used for normal check confirmed. This would allow the ability to wear the ability to spend a will without moving it on the chain.

Finally, with a cat, CSFS can be used to make more complex competencies. As we can see later in the series However, CSFS doesn't need to name any of this more advanced behavior, as the cat is alone able to do so.

Closing thoughts

CSFS is very fundamentally fundamental to providing simple ability to a simple ability to create a great deal to create great potential. Although examples of signed signed names, referring to the electronic network, relevant to any protocol make use of the Bitcol.

In addition to the French names, the production format is very useful than common control exceeding Utxo to a new public key. The same fundamental competence of “outdoor variables” after the truth of scratch verification stream can flow to anything, not just public keys. Leaf values, Hashlock customs, etc. Any script that is added to the face against the face of the fact.

In addition, CSFS is a great speaker recommendation. It has implements that have lived on the liquid network and elements (Cykbase customs) from 2016. In addition to 2018 is a bitcoin version.

CSFS is a critical proposal that goes back to the front of the start as I have been in this place, and the use of a wipeless use of the Favorite Payment, and Favorite Usage issues.
