Richard Stallman, the fervently committed founder of the free software movement, is discussing the term “libertarian,” when he stops talking abruptly and says, “Hello?”
I tell him I’m still listening, but he explains that the confused greeting wasn’t intended for me. Instead, he says a man’s voice – neither mine nor an echo of his – had just cut in with one word: “liberty.”
“Does that sort of thing happen a lot?” I ask. I hadn’t heard anything.
“Yes,” he says. “It wasn’t a voice I recognize.” He added, “It could be … ”
Then a quick burst of static made his next words inaudible.
It was a strange incident, but apparently not a new experience for Stallman, whose emails urge any NSA or FBI agents reading to “follow Snowden’s example” and blow the whistle.
Stallman seems to check all of the old school cypherpunk boxes: in addition to being an Edward Snowden admirer, he’s a hacker of the original ’70s and ’80s generation, a privacy activist, and a frequent invoker of liberty. As a result, cryptocurrency enthusiasts could be forgiven for thinking Stallman was also head-over-heels for bitcoin.
Before his oration on libertarianism was interrupted, he said that the right-wingers who made up a significant portion of bitcoin’s early adopters don’t really deserve the label. His own pro-freedom views are more “libertarian” than bitcoiners’ “anti-socialism,” he argued.
As we spoke, it became clear that Stallman doesn’t find the decade-old technology all that appealing, for more reasons than just politics.
“I have never used it myself,” he told CoinDesk.
If that’s surprising, keep in mind that fine distinctions matter a great deal to Stallman. For example, he wrote a 9,000-word explainer on the difference between the terms GNU and Linux.
In 40-ish words: GNU, which Stallman proposed in 1983, is an operating system using exclusively free software. Linux, created years later by Linus Torvalds, is a kernel. Many refer to packages combining the two as “Linux,” but Stallman insists that the proper term is GNU/Linux or just GNU.
He also wrote 3,000 words on the differences between free software and open source software. Advocates of both push for the freedom to use, study, change and redistribute software, but Stallman said that those similarities conceal “a deeply important moral disagreement” centered on freedom and human rights, which the free software movement stresses.
The Taler project’s maintainer Christian Grothoff told CoinDesk that the system is, rather, designed for a “post-blockchain” world.
Concerned with privacy…
It doesn’t even seem like the technology has been around long enough to already be thinking of a world after it, but to Stallman, bitcoin isn’t suitable as a digital payment system.
His biggest complaint: bitcoin’s poor privacy protections.
He told CoinDesk, “What I’d really like is a way to make purchases anonymously from various kinds of stores, and unfortunately it wouldn’t be feasible for me with bitcoin.”
Using a crypto exchange would allow that company and ultimately the government to identify him, he said. And as for mining the bitcoin himself, it’s a big investment and besides, he continued, “I’ve got other things I’d rather do.”
Asked what he thought about so-called privacy coins, Stallman said he’d gotten an expert to assess their potential, and “for each one he would point out some serious problems, perhaps in its security or its scalability.”
And speaking broadly, Stallman continued:
“If bitcoin protected privacy, I’d probably have found a way to use it by now.”
To be sure, Stallman is deeply concerned with surveillance by governments and corporations. His emails include a header urging “any NSA and FBI agents reading” to “follow Snowden’s example” – meaning, presumably, to blow the whistle on domestic spying by U.S. intelligence agencies.
…But not ‘perfect’ privacy
That pessimism aside, the GNU Project’s Taler does share some aspects with cryptocurrency projects – most notably it aims to fill the same niche.
Start with Taler’s intellectual lineage. It’s based on blind signatures, a cryptographic technique invented by David Chaum, whose DigiCash was among the first attempts at creating secure electronic money. Plus, Taler’s attempt to create a digital money that resists surveillance by governments and payments companies aligns it with many cryptocurrency projects.
Yet, Taler does not attempt to bypass centralized authority.
Payments are processed by openly centralized “exchanges” rather than peer-to-peer networks of miners because, Grothoff said, such a system “would again enable dangerous, money laundering kind of practice.”
Indeed, in a break with the anti-government ethos that has tended to characterize bitcoin and some of its peers, Taler’s design explicitly tries to block opportunities for tax evasion.
Speaking to this, Stallman told CoinDesk, “We need a state to do many vital jobs, including fund research, fund education, provide people with medical care – provide everyone with medical care – build roads, maintain order, provide justice, including to those who are not rich and powerful, and so the state’s got to bring in a lot of money.”
What a break from the political leanings of many of bitcoin’s first adherents.
“I wouldn’t want perfect privacy because that would mean it would be impossible to investigate crimes at all. And that’s one of the jobs we need the state to do.”
Privacy in the Taler system, then, is limited to users spending their digital cash. They are shielded from surveillance because, Grothoff said, “the exchange, when coins are being redeemed, cannot tell if it was customer A or customer B or customer C who received the coin, because they all look identical from the exchange.”
“Nobody,” he added, “exactly knows who has how many tokens.”
Merchants (or anyone) receiving payments, on the other hand, do so visibly and in the open, making it possible for governments to assess taxes on their income – not to mention harder for the recipients to participate in money laundering.
A place for crypto?
While Taler is not a cryptocurrency and doesn’t have a native asset (there are no talers or TalerCoins), as a new payment rail for existing assets, the system could support cryptocurrency at some point.
Just as euros (the first currency that will be supported by the system), dollars and yen could all be sent using Taler, so could bitcoin.
Similarly, while Taler is not a blockchain, a blockchain-based system could take the place of a bank within the system.
For users to be able to move euros into the Taler wallet, though, Taler exchanges will need to interact with the traditional banking system to withdraw that money. In this same way, a blockchain-based system could work with Taler exchanges to allow users to get access to their cryptocurrency.
Grothoff compared the act of moving bank deposits to a Taler digital wallet to taking cash out of an ATM. Coins in the wallet are stored locally on a user’s device, and if a user loses the key to their wallet, there’s nothing that can be done to recover it, much like the crypto space’s use of private/public key pairs.
Currently, Taler is in talks with European banks to allow withdrawal into the Taler wallet and also re-deposit from the Taler system back into the traditional banking system.
While the launch date on the project’s website still lists 2018, Grothoff said, it’s dependent of how quickly discussions with banks can be wrapped up. And he said, “The banks are not necessarily easy or cheap to deal with.”
Although, nothing about the traditional banking system per se is essential to Taler’s functioning (except perhaps for regulatory compliance). In principle, the “register-based system” that Taler plugs into could be a bank account or, in theory, a blockchain, said Grothoff.
If Taler gains traction, developers can experiment with different implementations and integrations – using banks or blockchains or whatever other register system they prefer. After all, Grothoff said:
“It’s free software.”
