Just a further follow up here please see below feedback from Max CEO of
Coinspaid - I asked him to send me a mail.
Peter - I can understand why some of our statistics seems off, some of our
clients when they have multiple outputs going to their cluster will query
each trx hash with a separate output address as for them they need each trx
or output deposit covered/guaranteed so we would count that trx hash each
time it is queried with a different output address as a trxs - this would
mean that value of our total processed is possibly a more
reflective indicator. Apologies for this inclarity we are not used to
communicating our statistics at all - its just not our nature.
I would think looking at Nov 2022 Stats - 900k unique trx hashes queried,
with 1.5m trxs on our count since trx hashes are queried with different
output addresses. The actual value is USD 220M benefiting from zero conf
acceptance.
See Maxes email below - I will also forward the email as is to the list
Hi Daniel,
Hope you are doing fine. I know you are in discussions with Bitcoin Core
team or RBF updates.
With current email, wanted to confirm that we are running quite a big
Bitcoin payment operation with over 300k incoming transactions, with 700+
inputs a month. Which is a fair percentage of overall BTC chain capacity
and we do enjoy zero conf flows that you offer. Our clients do like to give
instant experience to their end customers, I would not want to disappoint
them with news that “waiting for confirmations” is on a table again, after
all these years of smooth experience.
2 main production clusters are rotating around:
