PolarSys B612 font family

B612 is an highly legible open source font family designed and tested to be used on aircraft cockpit screens.

Main characteristics are:

Maximize the distance between the forms of the characters
Respect the primitives of the different letters
Harmonize the forms and their spacing

Distributed randomness beacon.

Verifiable, unpredictable and unbiased random numbers as a service.

This prototype implementation generates full-entropy bit-strings and posts them in blocks of 512 bits every 60 seconds. Each such value is sequence-numbered, time-stamped and signed, and includes the hash of the previous value to chain the sequence of values together and prevent even the source to retroactively change an output package without being detected.

A selection of currently implemented calls are listed below. Users submitting a request need to provide the pulse generation time in POSIX format (number of milliseconds since midnight UTC, January 1, 1970 (see http://en.wikipedia.org/wiki/Unix_time for more information and http://www.epochconverter.com for an online time converter.)

The reference document for version 2.0 of the beacon may be found at: https://nvlpubs.nist.gov/nistpubs/ir/2019/NIST.IR.8213-draft.pdf.
