Aether (https://getaether.net) also uses a roughly equivalent version of this I had thought, up to this point, that I ‘discovered’. I call it ‘Rolling Bloom’. (Not sure which implementation is first.)
Thanks for the pointer. I took a look at the code and it’s different. Looks like Aether maintains several bloom filters, each link to a given time range. In contrast the paper builds a different kind of bloom filter where hash functions can overlap.
Interesting, thanks for taking a look. That is correct. Aether also does some partial merging in the cases where the time range required does not exactly match the filter sequence.
