All the pieces constructed on high of Bitcoin that you’re conscious of at this time is due to the primitives that Bitcoin Script helps. What do I imply by primitives? The essential elements of a programming language that you should utilize to construct precise functions to do issues. No programming language was ever designed particularly for a single software, i.e. to construct one program. They’re designed to assist primary primitives, like mathematical operations to control information, or creating primary information buildings to retailer information in a sure manner, or operations to iterate by way of information as you manipulate it.
Primary primitives are designed in such a manner that builders can resolve learn how to use them with a purpose to create an precise software or program. The core design of the language doesn’t essentially deal with what folks will do with it, simply that the primitives of the language can’t be mixed in a manner that can both 1) fail to perform what the developer is attempting to perform with out them understanding why, or 2) accomplish what the developer is attempting to do in a manner that’s detrimental to the tip consumer.
Nobody designs a programming language considering from the outset “Oh, we need to allow builders to do A, B, and C, however fully stop them from doing X, Y, and Z.” (For extra technical readers right here, what I’m referring to right here is the objective of what the developer is constructing, not low stage technical particulars like how primitives are mixed).
Bitcoin Script isn’t any totally different than different programming languages besides in a single respect, what it means for a sure mixture of primitives to be detrimental to finish customers. Bitcoin has two properties that normal laptop functions don’t, the blockchain and what’s executed on it have to be totally verified by all customers operating a full node, and all the development of the system is secured by monetary incentives that should stay in stability. Apart from these further concerns, Script is like another programming language, it ought to embody any primitives that permit builders to construct helpful issues for customers that can’t be mixed in methods which are detrimental to customers.
The entire conversations round softforks so as to add covenants (new primitives) have devolved, not less than within the public sq., to ridiculous calls for of what they are going to be used for. That’s each not a attainable factor to do, and likewise not the vital factor to deal with. What might be constructed with Script is tangential to the dangers that have to be analyzed, how issues constructed work together with the bottom layer is the main threat. What prices will it impose, and the way can these be constrained? (This can be a large a part of the Nice Script Restoration proposal from Rusty). How can these prices on the bottom layer skew incentives? This can be a massive a part of the danger of MEV.
These questions may be analyzed with out focusing obsessively over each attainable factor that may be constructed with a primitive. Primitives may be constrained on the base layer when it comes to verification price and complexity. Most significantly, when it comes to incentives, what new primitives allow may be in contrast with issues which are already attainable to construct at this time. If new primitives merely enhance the belief mannequin for finish customers of techniques that may already be constructed which have an affect on the system incentives, with out materially worsening the affect they’ve on these incentives, then there is no such thing as a actual new threat launched.
These conversations want to begin specializing in what actually issues, new performance versus finish consumer hurt. They’ve derailed virtually fully, once more within the public sq., not technical circles, into arguments over whether or not finish customers ought to be allowed to do issues or not. That isn’t the dialog that issues. What issues is offering beneficial performance to finish customers with out creating detrimental penalties.
Folks have to deal with the primitives, and never the wild geese they hear within the distance.
