Wakefield Scott Stornetta (born June 1959) is an American physicist and scientific researcher.His 1991 paper "How to Time-Stamp a Digital Document”, [1] co-authored with Stuart Haber, won the 1992 Discover Award for Computer Software and is considered to be one of the most important papers in the development of cryptocurrencies.
Linked timestamping is inherently more secure than the usual, public-key signature based time-stamping. All consequential time-stamps "seal" previously issued ones - hash chain (or other authenticated dictionary in use) could be built only in one way; modifying issued time-stamps is nearly as hard as finding a preimage for the used cryptographic hash function.
In computing, timestamping refers to the use of an electronic timestamp to provide a temporal order among a set of events.. Timestamping techniques are used in a variety of computing fields, from network management and computer security to concurrency control.
The term "timestamp" derives from rubber stamps used in offices to stamp the current date, and sometimes time, in ink on paper documents, to record when the document was received. Common examples of this type of timestamp are a postmark on a letter or the "in" and "out" times on a time card .
This is a list of all Internet Relay Chat commands from RFC 1459, RFC 2812, and extensions added to major IRC daemons. Most IRC clients require commands to be preceded by a slash (" / "). Some commands are actually sent to IRC bots ; these are treated by the IRC protocol as ordinary messages, not as / -commands.
The Time to Live is an indication of an upper bound on the lifetime of an internet datagram. It is set by the sender of the datagram and reduced at the points along the route where it is processed. If the time to live reaches zero before the internet datagram reaches its destination, the internet datagram is destroyed.
Whenever a transaction initiated, it receives a timestamp. The transaction's timestamp indicates when the transaction was initiated. These timestamps ensure that transactions affect each object in the same sequence of their respective timestamps.
According to the RFC 3161 standard, a trusted timestamp is a timestamp issued by a Trusted Third Party (TTP) acting as a Time Stamping Authority (TSA). It is used to prove the existence of certain data before a certain point (e.g. contracts, research data, medical records, ...) without the possibility that the owner can backdate the timestamps.
