🗒️ Summary of this message: GAP600's research is based on monitoring transactions and network activity. They do not assess specific hashing pools or engage with clients for their names and applications. Coinpaid's root addresses can be validated using tools like Chainanlysis. It is possible to reach out to Max at Coinpaid to confirm GAP600's use. Changelly may not have implemented GAP600's service across all its offerings.
📝 Original message:
For clarity purposes.
1. Our research is based on monitoring main net transactions and network
activity - as too is our risk engine. We do not engage in specific hashing
pool assessments or research.
2. It is not easily possible or comfortable to engage with our clients
to offer up their client names and applications - the competition is fierce
and like other industries it is not an acceptable approach to ask.
3. The information offered by Coinpaid and posted on this list, provides
root addresses which using tools like Chainanlysis, or
similar service providers can confirm these addresses are associated with
Coinspaid. This can validate a significant amount of our traffic.
4. Based on the information provided it will be very possible to reach
out to Max at Coinpaid - and will be able to confirm GAP600 use with
Coinspaid. This is in addition to me posting an email from Max back in Dec
2022 to this list confirming all of this information.
5. It is more than likely that Changelly has not implemented our
service across all irts offerings, a large section of their business is
servicing partners.

🗒️ Summary of this message: The sender disputes the recipient's assessment of their dishonesty, stating that it is based on baseless assumptions and lacks commercial experience. They provide evidence to support their claims and challenge the recipient to provide concrete examples.
📝 Original message:
Your assessment of my dishonesty is based on your assumption of how I
should be running GAP600, your assumptions are baseless and lack commercial
experience and likewise your conclusions are false.
I have provided already back in December clear access to clarify opposite
our clients corroborated with easily verifiable trxs activity of a major
client of ours. This is more than enough to corroborate our statistics.
As far as validating real RBF adoption I have offered a clear option here
https://github.com/bitcoin/bitcoin/pull/28132#issuecomment-1661960440
something like this or similar would offer a clear assessment of adoption.
Since you are not able to provide documents or public emails of hashing
pools confirming there adoption of Full RBF.

🗒️ Summary of this message: The author claims that the research is not thorough and reaches an incorrect conclusion. They provide evidence of Coinspaid's use of 0-conf and offer to connect with the CEO for confirmation. They also mention speaking to Changelly for confirmation of GAP600 as a service provider. The author questions the need for full RBF and requests contacts of mining pools that have adopted it.
📝 Original message:
Your research is not thorough and reaches an incorrect conclusion.
As stated many times - we service payment processors and some merchants
directly - Coinspaid services multiple merchants and process a
significant amount of BTC they are a well known and active in the space -
as I provided back in December 2022 a email from Max the CEO of Coinspaid
confirming their use of 0-conf as well as providing there cluster addresses
to validate there deposit flows see here again -
https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2022-December/021239.html
- if this is not sufficient then please email support at coinspaid.com and ask
to be connected to Max or someone from the team who can confirm Conspaid is
clients of GAP600. Max also at the time was open to do a call, I can check
again now and see if this is still the case and connect you.
That on its own is enough of a sample to validate our statistics.
I have also spoken to Changelly earlier today and they offered to email pro
@ changelly.com and they will be able to confirm GAP600 as a service
provider. Also please send me the 1 trx hash you tested and I can see if it
was queried to our system and if so offer some info as to why it wasnt
approved. Also if you can elaborate how you integrated with Changelly - I
can check with them if that area is not integrated with GAP600.
As the architect of such a major change to the status of 0-conf
transactions I would think you would welcome the opportunity to speak to
business and users who actual activities will be impacted by full RBF
becoming dominant.
Are you able to provide the same i.e emails and contacts of people at
the mining pools who can confirm they have adopted FULL RBF ?

📅 Original date posted:2023-07-31
🗒️ Summary of this message: The implementation of full Replace-by-Fee (RBF) could negatively impact merchants and users who rely on 0-conf transactions. GAP600 has seen strong usage of their service and believes the adoption of RBF will change their business.
📝 Original message:
This would unnecessarily and extremely negatively impact merchants and
users who choose to accept 0-conf while using mitigation tools like GAP600.
This negative impact could be avoided by simply adding first seen safe rule
- ie a trx can be replaced but needs to include the original outputs.
At GAP600 we continue to see strong use of our service for BTC we have seen
circa 350k unique trx hash per month (over the last 3 months) requested to
our platform. Our clients include - Coinpayments, Coinspaid and Changelly.
Given the period of Mempool being full we have seen an increase in the fee
required in order to be approved by our platform for trx. This is not an
insignificant use case and one which can be easily maintained as is.
We have provided further statistics in the past and direct feedback from
Coinspaid CEO with in the mailing list see here -
https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2022-December/021240.html
We have not seen any impact of full RBF on double spend rates for our trxs
which seems to put in large question the stated figure of 40% adoption by
miners at such a rate of adoption we would expect to see a large increase
in double spends. We expect once this setting becomes default this will
greatly change the adoption of this service.
GAP600 model targets not to get it wrong and as such we are very sensitive
to any double spend which we get wrong in predicting as we reimburse our
clients. GAP600 is not a payment processor; rather services payment
processors, merchants and non custodial liquidity providers which service
non-custodial wallets.
