"Nanoflakes" is a specification for unique identifiers which can be generated locally or from a remote server. The specification is designed to be simple and easy to implement, and to be compatible with Twitter's Snowflake algorithm, which Nanoflakes is based on.
A nanoflake is a 64-bit signed integer, and supports 1024 unique ID generators, each being able to generate 4096 (2^12) unique IDs per millisecond, and with 41-bit timestamps.
The main and only difference between a nanoflake and a Twitter Snowflake
is that nanoflakes merges Twitter's 5-bit datacenter ID and 5-bit worker
ID into a single 10-bit generator ID.
Additionally, the specification suggests encoding nanoflakes using base-36, in order to fit the largest possible nanoflake into a 13-character string.
The official, full specification can be found here.
