The [Private, Shielded] Path to Better Payments with Trevor Filter from Flexa - ZconVI #zcash Zcash Foundation 2025-03-06 | Credit and debit cards were invented decades before the internet, and continue to entrench fundamental shortcomings that waste money and compromise our privacy. Unfortunately, most of the current attempts to take crypto payments mainstream simply bolt on top of these legacy systems. If we're going to realize the cypherpunks' vision of electronic money, we need to hard fork the payments timeline to better protect our personal data. Trevor Filter will share what Flexa has learned over the past seven years of building a purely digital payments system, and offer new ideas for helping crypto supplant fiat money in global commerce.Flexa's Transparency: flexa.co/transparencyTechnical Level: BasicTimestamps:00:00 Intro01:01 Flexa's Vision for Private and Shielded Payments01:53 Agenda02:05 About Me04:30 Discovery #106:54 About Flexa08:03 Discovery #210:57 Discovery #313:27 Flexa's Payment Technologies15:15 Flexa and Zcash16:03 Electronic cash needs to be fast and cheap17:51 Privacy Concerns in Current Payment Systems19:50 Flexa and User Data Collection21:40 Flexa Worldwide Government Information Requests22:38 What's Next24:50 Wrapping UpSpeaker:- Trevor Filter is a cofounder of Flexa, a payments platform focused on making it as simple as possible for every business to accept digital assets.
