Weassume that the identity (public key) of the node can be ex-tracted from its signature, e.g., using ECDSA.

Then the other answered again, “Sir Gawain, so may I thrive as I am fain to take this buffet at thine hand,” and he quoth further, “Sir Gawain, it liketh me well that I shall take at thy fist that which I have asked here, and thou hast readily and truly rehearsed all the covenant that I asked of the king, save that thou shalt swear me, by thy troth, to seek me thyself wherever thou hopest that I may be found, and win thee such reward as thou dealest me to-day, before this folk.”

From the Introduction to Ed25519, there are some speed benefits, and some security benefits. One of the more interesting security benefits is that it is immune to several side channel attacks: No secret array indices. The software never reads or writes data from secret addresses in RAM; the pattern of addresses is completely predictable. The software is therefore immune to cache-timing attacks, hyperthreading attacks, and other side-channel attacks that rely on leakage of addresses through the CPU cache. No secret branch conditions. The software never performs conditional branches based on secret data; the pattern of jumps is completely predictable. The software is therefore immune to side-channel attacks that rely on leakage of information through the branch-prediction unit. For comparison, there have been several real-world cache-timing attacks demonstrated on various algorithms. http://en.wikipedia.org/wiki/Timing_attack

More "sales pitch" comes from this IETF draft: While the NIST curves are advertised as being chosen verifiably at random, there is no explanation for the seeds used to generate them. In contrast, the process used to pick these curves is fully documented and rigid enough so that independent verification has been done. This is widely seen as a security advantage, since it prevents the generating party from maliciously manipulating the parameters. – ATo Aug 21, 2016 at 7:25

const palette: { [key: string]: string } = {...

Object literals don't have index signatures. They are assignable to types with index signatures if they have compatible properties and are fresh (i.e. provably do not have properties we don't know about) but never have index signatures implicitly or explicitly.

Which... is confusing because Palette technically does have an index signature Palette is a mapped type, and mapped types don't have index signatures. The fact that both use [ ] is a syntactic coincidence.

Generate type with the index signature: interface RandomMappingWithIndexSignature { stringProp: string; numberProp: number; [propName: string]: string | number | undefined; }

we have no way to know that the line nameMap[3] = "bob"; isn't somewhere in your program

The other commenters are right about the potential solutions. However, it is actually considered a best practice to move the object with the index signature to a nested property.Said differently: No property in the object with the index signature should depart from how the index signature is typed.

Like others have noted, your function does not conform to index signature. [key: string]: string means "all fields are strings" and on the next line you declare a field with function in it.This can be solved by using union types:type IFoo = { [foo: string]: string } & { fooMethod(fooParam: string): void }

So now the question is, why does Session, an interface, not get implicit index signatures while SessionType, an identically-structured typealias, *does*? Surely, you might again think, the compiler does not simply deny implicit index signatures tointerface` types? Surprisingly enough, this is exactly what happens. See microsoft/TypeScript#15300, specifically this comment: Just to fill people in, this behavior is currently by design. Because interfaces can be augmented by additional declarations but type aliases can't, it's "safer" (heavy quotes on that one) to infer an implicit index signature for type aliases than for interfaces. But we'll consider doing it for interfaces as well if that seems to make sense And there you go. You cannot use a Session in place of a WithAdditionalParams<Session> because it's possible that someone might merge properties that conflict with the index signature at some later date. Whether or not that is a compelling reason is up for rather vigorous debate, as you can see if you read through microsoft/TypeScript#15300.

why is Session not assignable to WithAdditionalParams<Session>? Well, the type WithAdditionalParams<Session> is a subtype of Session with includes a string index signature whose properties are of type unknown. (This is what Record<string, unknown> means.) Since Session does not have an index signature, the compiler does not consider WithAdditionalParams<Session> assignable to Session.

A ring signature is created when the sender of a transaction is mixed together with a random collection of other IDs that basically serve as a decoy. This process produces a unique digital signature for the transaction, but it blurs the identity of the real sender.

A cognitive signature™ encodes the exact structure of a graph.●It is a lossless encoding, similar to a Gödel numbering. *●For unlabeled graphs, integers are sufficient for a cognitive signature.●For example, 0 maps to and from an empty graph with no nodes or arcs.●1, 2, 3, 4, 5, and 6 can be mapped to and from the following graphs:●To encode the structure of conceptual graphs in Cognitive Memory, the cognitive signatures are based on generalized combinatorial maps. **By contrast, a word vector encodes labels, but not structure.●A word vector is a “bag of labels” that ignores the graph connections.●Word vectors are often used for measuring the similarity of documents.●But they discard the structural information necessary for reasoning, question answering, and language understanding.
