NextStream V2 has just gained another 0.5ms in speed...we are nearing the absolute limit of how fast shreds can be ingested & decoded!
While 0.5ms may not seem like a lot, when it comes to being first, it matters.
Our team just finished a late night crunch to deploy a custom feature for a client who had a special need...at NextBlock, we're open to feedback, feature requests, & more.
If you have a special request or idea, feel free to shoot us a DM!
