My heretical take of the day: 1/ Classical double-entry ledgers don’t store sufficient information to permit tracing specific assets to specific liabilities except in the simplest of cases. 2/ Being able to do so actually matters, especially in fintech, and to non-bank actors involved in programmatic flow-of-funds orchestration. Jotted down some notes here for the curious: formance.com/blog/engineerin…

There Is a wave of open source ledger / financial database that’s happening, bundling integrations, a DSL that describes transactions, and a ledger that can execute transactions correctly. @amanda_robs and I sat down with @superzamp about @formancehq, which you should listen to!

Thinking this through, it’s the type of government-caused crisis that could lead to a CBDC. Because I don’t know how businesses could practically operate with only a $250k max in each account. They’d have to keep buying and selling T-bills. Instead they’d want to somehow send $1 worth of T-bills back and forth without doing constant buys and sells. They’d want fully digital dollars where their counterparty isn’t a bank, but the central bank… And that becomes a central bank digital currency (CBDC).

If businesses lose money on deposit, then every business in the country will move all cash above $250K into Treasuries and we’ll have a system-wide bank run at Twitter speed. They’ll tell their banker, “the only counterparty I want is the US Treasury.”

I don't think people understand. We did everything we were supposed to with the iOS app. Try downloading it (while you can?). You can't sign up, because Apple says no. We don't mention subscriptions. You can't upgrade. You can't access billing. We did all of it! Wasn't enough.
