Sentence examples for computational puzzle from inspiring English sources

The blockchain is composed, as you might guess, of "blocks," each consisting of a list of recent bitcoin transactions, time-stamped and verified by one of the network's "miners"—computers that secure a block's inclusion on the chain by solving a computational puzzle called a proof of work.

The authors examined captive pigeons' ability to navigate the traveling-salesman problem, a classic computational puzzle that asks you to devise the shortest round-trip route that stops at each city once.

In order to prevent MITM attack even for a new IP address, we propose a new IP/MAC mapping conflict resolution mechanism based on computational puzzle and voting.

There are other proposals that involve "computational puzzles": time-consuming tasks the sender's computer must perform, unnoticeable to someone who is sending e-mail normally, but too much for someone sending e-mail in bulk.

The proposed scheme is based on two key concepts: long-term IP/MAC mapping table and computational puzzle-based voting.

The proposed computational puzzle-based voting scheme can provide fairness among different nodes only when the computation power of the CPUs of those machines is not significantly different.

The computational puzzle-based voting prevents ARP poisoning-based MITM attack whenever a machine is rebooted or a new machine is added.

We use computational puzzle-based voting, which corresponds to the case (C) in Figure 1, to solve the poisoning problem for this particular case.

The proposed scheme shares the basic concept, preservation of (IP, MAC) mapping while the node corresponding to the original MAC address is alive, with the Antidote, but resolves the race condition in a different way using computational puzzle-based voting.

Conventional computational puzzles [16 18] based on hash functions might satisfy most of the above requirements.
