proof machine
1Proof theory — is a branch of mathematical logic that represents proofs as formal mathematical objects, facilitating their analysis by mathematical techniques. Proofs are typically presented as inductively defined data structures such as plain lists, boxed… …
2Proof-of-payment — or POP is an honor based fare collection approach used on many public transportation systems. Instead of checking each passenger as they enter a fare control zone, proof of payment requires that each passenger carry a ticket or pass proving that… …
3Proof of impossibility — A proof of impossibility, sometimes called a negative proof or negative result , is a proof demonstrating that a particular problem cannot be solved, or cannot be solved in general. Often proofs of impossibility have put to rest decades or… …
4Proof of knowledge — In cryptography, a proof of knowledge is an interactive proof in which the prover succeeds convincing a verifier that it knows something. What it means for a machine to know something is defined in terms of computation. A machine knows something …
5Proof-of-work system — A Proof of work ( POW ) system (or protocol, or function) is an economic measure to deter denial of service attacks and other service abuses such as spams on a network by requiring some work from the service requester, usually meaning processing… …
6Machine that always halts — In computability theory, a machine that always halts also called a decider (Sipser, 1996) or a total Turing machine (Kozen, 1997) is a Turing machine that halts for every input. Because it always halts, the machine is able to decide whether a… …
7Proof Of Deposit - POD — The verification that the dollar amount of a check or draft being deposited is correct. Proof of deposit is accomplished when the amount written on the check is compared to the amount on the deposit slip. This is the second step in the process of …

10Turing's proof — First published in January 1937 with the title On Computable Numbers, With an Application to the Entscheidungsproblem , Turing s proof was the second proof of the assertion (Alonzo Church proof was first) that some questions are undecidable :… …
