SCRU128: Sortable, Clock and Random number-based Unique identifier

SCRU128 ID is yet another attempt to supersede UUID in the use cases that need decentralized, globally unique time-ordered identifiers. SCRU128 is inspired by ULID and KSUID and has the following features:

  • 128-bit unsigned integer type
  • Sortable by generation time (as integer and as text)
  • 26-digit case-insensitive portable textual representation
  • 44-bit biased millisecond timestamp that ensures remaining life of 550 years
  • Up to 268 million time-ordered but unpredictable unique IDs per millisecond
  • 84-bit layered randomness for collision resistance
import Scru128

print(scru128()) // e.g. "00RNOS8DGRPBRNGKN57QHSVFDC"
print(scru128()) // e.g. "00RNOS8DGRPBRNIKN57RO9NCBG"

See SCRU128 Specification for details.
