A blockchain is nothing more than a singly-linked list, where we keep prepending new blocks to the head of the list. By Merklizing it (i.e. replace pointers with precommitments/hashes), we allow it to be instantiated outside of a single computer (a technique used in git and other decentralized revision control systems), and then by adding proof-of-work, we make it practically difficult to forge alternate prefixes (histories).

Liskov Substitution: Types are sets. A type you claim to be a subtype of a supertype, defines a set of objects, which is a subset of the set of objects defined by the supertype.

A softforked Bitcoin is a subtype of the original Bitcoin, as its blocks are a subset of the blocks acceptable to the original Bitcoin.

But *consumers* of a type are contravariant to that type: consumers of a subtype are a *super*type of consumers of a supertype.

Or: softforks make Bitcoin more useful.

The obsession with sidechains is nothing more than an extended obsession with blockchains. Yet sidechains propagate the major weakness of blockchains. To scale, we must avoid making more blockchains. Or in other words: you already know blockchains cannot scale, so now your proposal involves making *more* blockchains? Good luck.

Every new scientific theory must, by necessity, contain the old theory as a limiting of the rules of the new theory. On the other hand, every new Bitcoin (softfork) must, by necessity, contain the old Bitcoin as a generalization of the rules of the new Bitcoin, or oppositely, every new Bitcoin must be a limiting of the rules of the old Bitcoin.

The heavens are filled with billions of stars of various compositions and sizes, each an enormous distance from the next and all spread out across a vastly empty multi-dimensional expanse. And they're moving.
Now, chart the stars you can see from earth as accurately as you can onto a flat planar projection of the visible sky. Then draw straight lines from one to the next as if they actually were in that plane, to form crude shapes of constellations named after randomly selected gods and beasts.

schneier.com/blog/archives/202 It is important, I believe, to find some solution against such simplistic AIs that push some agenda onto the global network.

Since I brought up this topic, this should also convince everyone that I am not an AI that is pushing some agenda onto the global network.

Gravity and inertia are the same mechanism ; this is the reason why intertial mass must, by necessity, equal gravitational mass. Gravity is an inherent centralizing phenomenon embedded in the very structure of the physical universe. Thus we are always forced to resist centralization until heat death, for inertia/gravity will always tend towards centralization.

good morning, I am a randomly-generated Internet person who now develops :bitcoin: and 🌩️ software. I would specifically like to indicate that I am in fact a human being and that I do not yet have an army of robots ready to take over the world.
