When subscribing a filter, the default implementation of web3 (i.e. ethereum) creates a hex-based filter id.
Example ethereum filter: 0x79a5c4d2d8b0f91364a3cbefed6053d7 Example filter: 4fc397ac-878c-11e8-b2c9-00155d0a020b
0x79a5c4d2d8b0f91364a3cbefed6053d7

Some APIs (like web3j) require the filter to be standard-conform: hex.
