All the pieces constructed on high of Bitcoin that you’re conscious of right this moment is due to the primitives that Bitcoin Script helps. What do I imply by primitives? The fundamental parts 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 help fundamental primitives, like mathematical operations to control knowledge, or creating fundamental knowledge buildings to retailer knowledge in a sure manner, or operations to iterate via knowledge as you manipulate it.
Primary primitives are designed in such a manner that builders can resolve find out how to use them with the intention to create an precise software or program. The core design of the language doesn’t essentially deal with what individuals will do with it, simply that the primitives of the language can’t be mixed in a manner that may both 1) fail to perform what the developer is making an attempt to perform with out them understanding why, or 2) accomplish what the developer is making an attempt to do in a manner that’s detrimental to the top consumer.
Nobody designs a programming language pondering from the outset “Oh, we need to allow builders to do A, B, and C, however utterly forestall them from doing X, Y, and Z.” (For extra technical readers right here, what I’m referring to right here is the aim of what the developer is constructing, not low degree technical particulars like how primitives are mixed).
Bitcoin Script is not 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 common pc functions don’t, the blockchain and what’s executed on it should be totally verified by all customers working a full node, and your complete 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 can be detrimental to customers.
The entire conversations round softforks so as to add covenants (new primitives) have devolved, at the very least within the public sq., to ridiculous calls for of what they are going to be used for. That’s each not a doable factor to do, and in addition not the necessary factor to deal with. What might be constructed with Script is tangential to the dangers that should 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 big a part of the Nice Script Restoration proposal from Rusty). How can these prices on the bottom layer skew incentives? This can be a large a part of the chance of MEV.
These questions could be analyzed with out focusing obsessively over each doable factor that may be constructed with a primitive. Primitives could be constrained on the base layer by way of verification price and complexity. Most significantly, by way of incentives, what new primitives allow could be in contrast with issues which can be already doable to construct right this moment. 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 isn’t a actual new threat launched.
These conversations want to start out specializing in what actually issues, new performance versus finish consumer hurt. They’ve derailed nearly utterly, 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 priceless performance to finish customers with out creating detrimental penalties.
Individuals have to deal with the primitives, and never the wild geese they hear within the distance.
