What Bitcoin Did with Peter McCormack
Business:Investing
“This was the reason why I think ecash is coming back now: because it needed Bitcoin. Ecash is almost worth nothing if you don’t have a free sovereign monetary layer below it… and we found the base money of the internet.”
— Calle
Calle is a Bitcoin and Lightning developer contributing to LNBits and the Cashu ecash system. In this interview, we discuss Cashu’s mission and development, undertake a live demonstration of it in action, the importance of privacy, removing ideology from Bitcoin, and the future of AI and robots.

“By providing a high degree of privacy in payments, cash helps to slow the growing information asymmetry between consumers and companies… between citizens and public authorities… privacy is crucial for individuals to safeguard their position when dealing with organisations which are more powerful than a single person.” Not the words of an anarcho-capitalist, but a prominent Deutsche Bank economist from 2019.
It is a truism that privacy is the bedrock of democracy. The problem is we’re sleepwalking into a cashless society where digital payments are tracked, recorded and stored. You can learn everything about someone through their transactions. Privacy in other areas means nothing in this environment. The issue has been how to replicate the utility of cash in the digital world.
David Chaum solved this problem in 1982: his dissertation “Computer Systems Established, Maintained and Trusted By Mutually Suspicious Groups” was the original blueprint for blockchains (excluding the proof of work consensus mechanism). His company Digicash launched ecash in 1995, predicated on Chaum’s blind signature innovation. For various reasons, ecash did not take root. Until now.
Amongst a small number of initiatives aiming to revive ecash under the Bitcoin umbrella, is Cashu, which allows for private ecash payments over the Lightning Network. It is essentially digital cash, backed by Bitcoin. It requires no accounts or personal information, and everyone involved in the system is blind to other users' transactions.
There are tradeoffs: it’s a custodial system where sats are deposited in ‘mints’ to create ecash. The creator Calle, a respected Bitcoin and Lightning Network developer, is working on technical solutions to overcome concerns. Even so, given how well the test version of Cashu is working, Cashu could be the go-to digital cash feature we’re all using very soon, and the feature that enables the next cycle of adoption.

What Bitcoin stands for and should be is a debate that has been raging since 2009. Bitcoin’s unique characteristics have drawn many people into its gravity. The realisation that its immaculate conception may never be replicated has resulted in many of those same people guarding Bitcoin’s development with uncompromising zeal.
The result has been the rise of Bitcoin Maximalism. Maximalist ideology can be a fuzzy concept: there are no clearly agreed rules or principles; there have been various iterations with different priorities over time. However, it is clearly characterised by conservatism over the development of the protocol, and intolerance for those with differing attitudes.
Nevertheless, that is not to say that Bitcoin development can forever remain in stasis. There are and have been pressures requiring upgrades both to the base layer, and in the development of additional layers. This means there is always a creative tension on what changes are required, and how quickly these need to be implemented.
Further, as Bitcoin has no leader, it has engendered an ecosystem where advocates organically emerge, who can gain traction and have an outsized influence on the community. This creates further tensions as Bitcoin’s purpose is being proselytized using competing and sometimes muddied beliefs.
Thus, it is important that Bitcoiners enable an open dialogue where all ideas are questioned, scrutinized and tested. And such debates should be open to all Bitcoiners, without fear or favour to any powerful interests. Is the question therefore how intolerant we should be of those with differing views? And, can we live without trolling, or is this a necessary defensive tool?
