"On the 30th of September, 2023, Samourai Wallet initiated a pre-planned server maintenance phase. The scheduled downtime was initially pegged at two hours, starting from 13:00 UTC; however, due to unforeseen circumstances, Samourai later extended the downtime of their wallet server, including their self-hosted public node, to just under 10 hours."
"The maintenance period acted as an unexpected quasi-experiment. With self-hosted Dojo users running Whirlpool without interruption, a unique opportunity arose to evaluate the volume of Whirlpool users dependent on Samourai's self-hosted public node."
"Whirlpool users' continuing remixes without interruption constituted 85-90% of the total user base actively mixing before the downtime."
"This data provides a transparent and verifiable metric, measuring the volume of Whirlpool users reliant on Samourai Wallet's public node, a figure now confirmed to be a minority of only 10-15% of the Whirlpool community. Due to the public nature of the Bitcoin blockchain, anybody can verify the credibility of this data independently."
"The overarching mission of Whirlpool is achieving complete decentralization. The next major milestone is eliminating the need for a centralized coordinator, perceived as Whirlpool's last primary attack vector."
