Is this technologically possible? The obstacles are political -- some of the most powerful forces in government are devoted to the control of these tools. In short, there is a war going on between those who would liberate crypto and those who would suppress it.
The seemingly innocuous bunch strewn around this conference room represents the vanguard of the pro-crypto forces. Though the battleground seems remote, the stakes are not: The outcome of this struggle may determine the amount of freedom our society will grant us in the 21st century. To the Cypherpunks, freedom is an issue worth some risk.
The term cypherpunk is mildly ambiguous. In most contexts it means anyone advocating cryptography as a tool for social change, social impact and expression. However, it can also be used to mean a participant in the Cypherpunks electronic mailing list described below. The two meanings obviously overlap, but they are by no means synonymous. Documents exemplifying cypherpunk ideas include Timothy C. John Gilmore said he wanted "a guarantee -- with physics and mathematics, not with laws -- that we can give ourselves real privacy of personal communications.
The Cypherpunk Manifesto stated "Cypherpunks deplore regulations on cryptography, for encryption is fundamentally a private act. Most were passionately opposed to various government attempts to limit cryptography — export laws , promotion of limited key length ciphers, and especially escrowed encryption. Anonymity and pseudonyms[ edit ] The questions of anonymity , pseudonymity and reputation were also extensively discussed. Arguably, the possibility of anonymous speech, and publication is vital for an open society and genuine freedom of speech — this is the position of most cypherpunks.
See Wikipedia's guide to writing better articles for suggestions. October Learn how and when to remove this template message A whole set of issues around privacy and the scope of self-revelation were perennial topics on the list. Consider a young person who gets "carded" when he or she enters a bar and produces a driver's license as proof of age. The license includes things like full name and home address; these are completely irrelevant to the question of legal drinking.
However, they could be useful to a lecherous member of bar staff who wants to stalk a hot young customer, or to a thief who cleans out the apartment when an accomplice in the bar tells him you look well off and are not at home. Is a government that passes a drinking age law morally obligated to create a privacy-protecting form of ID to go with it, one that only shows you can legally drink without revealing anything else about you?
In the absence of that, is it ethical to acquire a bogus driver's license to protect your privacy? For most cypherpunks, the answer to both those questions is "Yes, obviously! Should there be some restrictions on what he or she learns about you? Or a company that issues a frequent flier or other reward card, or requires registration to use its website? Or cards for toll roads that potentially allow police or others to track your movements?
Or cameras that record license plates or faces on a street? Or phone company and Internet records? In general, how do we manage privacy in an electronic age? Cypherpunks naturally consider suggestions of various forms of national uniform identification card too dangerous; the risks of abuse far outweigh any benefits. Censorship and monitoring[ edit ] In general, cypherpunks opposed the censorship and monitoring from government and police. In particular, the US government's Clipper chip scheme for escrowed encryption of telephone conversations encryption supposedly secure against most attackers, but breakable by government was seen as anathema by many on the list.
This was an issue that provoked strong opposition and brought many new recruits to the cypherpunk ranks. List participant Matt Blaze found a serious flaw [27] in the scheme, helping to hasten its demise. Steven Schear first suggested the warrant canary in to thwart the secrecy provisions of court orders and national security letters.
As a result, Cypherpunks have discussed and improved steganographic methods that hide the use of crypto itself, or that allow interrogators to believe that they have forcibly extracted hidden information from a subject. For instance, Rubberhose was a tool that partitioned and intermixed secret data on a drive with fake secret data, each of which accessed via a different password.
Interrogators, having extracted a password, are led to believe that they have indeed unlocked the desired secrets, whereas in reality the actual data is still hidden. In other words, even its presence is hidden. Likewise, cypherpunks have also discussed under what conditions encryption may be used without being noticed by network monitoring systems installed by oppressive regimes. Activities[ edit ] As the Manifesto says, "Cypherpunks write code"; [20] the notion that good ideas need to be implemented, not just discussed, is very much part of the culture of the mailing list.
John Gilmore , whose site hosted the original cypherpunks mailing list, wrote: "We are literally in a race between our ability to build and deploy technology, and their ability to build and deploy laws and treaties. Neither side is likely to back down or wise up until it has definitively lost the race. Expert panels[ edit ] Cypherpunks also participated, along with other experts, in several reports on cryptographic matters. At the time, the Data Encryption Standard with bit keys was still a US government standard, mandatory for some applications.
Don't ask permission," Smuggler , a crypto-native developer and philosopher so dedicated to privacy he usually appears in a mask, told CoinDesk over Jitsi, the open-source encrypted video service.

Ideologies and frustrations — the tone among committed cypherpunks shifted markedly over 20 years, from prodding to flabbergasted. Eric Hughes would write gently in 's " A Cypherpunk's Manifesto " about how, with cryptography, "in most cases, personal identity is not salient.
Are you stupid? Code embedded with ideas now has a cash value. But it also points to a worldview that moved from closing blinds to kicking down doors. In fact, it enhances it. Perhaps foremost among them is Taaki. The libbitcoin software is a library for building applications on the Bitcoin protocol. White papers are normal for software in this industry, but manifestos are a mood. Taaki released the libbitcoin manifesto in , after tensions arose between him and other contributors to Bitcoin Core the software that runs the protocol's software.
Read more: Bitcoin and the Rise of the Cypherpunks The manifesto signals that libbitcoin's intent is much larger than Bitcoin's, not even mentioning cryptocurrency until the fifth page of a seven-page document. Instead, it takes on much larger questions about how people approach the world, arguing: "Independence and autonomy is the ability to act.
If we always need third parties and central organisations to resolve disputes, solve our problems and coordinate us then we are doomed as a species. Central authorities are always a magnet for corruption and that will never change. Learn to be self reliant and make things happen. The space has been colonized by entrepreneurs motivated not by mission but money.

But the notion of counterfeiting only makes sense when there's a physical bill in the first place. In the digital world, a bill is just information. The "real bill" is just a sequence of bytes. How is this problem solved with digital payments schemes like PayPal? Simple: PayPal's servers enforce the "anti-counterfeiting.
This protects the system from double spending, but at the expense of giving PayPal complete control over the monetary system. PayPal's intellectual descendants include the entire fintech industry today, including Square founded in and Stripe founded in , all of which began with a centralized database at their core. But if you could solve the double spend problem without relying on a trusted third party, you could potentially create a digital currency native to the Internet.
Was this possible? No one was sure. So the cypherpunks got to work. Chaumian eCash David Chaum is considered by many to be the father of the cypherpunk movement. A prolific academic researcher, Chaum single-handedly created the field of anonymous communications research and invented many cryptographic protocols, including group signatures, mix networks, and blind signatures.
DigiCash used novel cryptography to ensure user privacy while solving the double spend problem. The underlying algorithm was known as eCash, first published in and later improved by other cryptographers. What follows is a simplified description of the eCash algorithm: First, coins are issued to users by a bank.
Each coin has a specific denomination and serial number, which are cryptographically signed by the bank. When a merchant receives a coin from a user, the merchant relays the coin to the issuing bank. The bank verifies that the signature over the denomination and serial number is valid and whether the coin has been previously spent.
If these check out, the bank ensures that all spent coins are real and haven't been spent before. The merchant is then paid out for whatever the coins were worth. On the face, this setup solves the double spend problem, but it seems quite centralized given the presence of the bank.
And how does this achieve privacy? Well, there's a little extra cryptographic magic for that. Accompanying this request she generates a random serial number for the new bill she's creating, plus a random "blinding factor". This blinding factor will be used to obfuscate which serial number belongs to her. The blind signature scheme lets Alice remove the blinding factor, while still having a valid signature on the coin. In other words, the eCash issuer cannot track the blinded coins they signed.
All they can see is the random unblinded serial numbers they eventually verify for merchants. And all the issuer is able to track are the total number of coins in each denomination and whether particular serial numbers have already been spent. A diagram of the Chaumian eCash protocol Chaumian eCash was a major leap forward in digital currencies. But in , the company founded on eCash DigiCash went bankrupt. It ultimately lost out in user adoption against credit cards and less private payments systems like PayPal.
And of course, when the company liquidated, its entire cash ecosystem evaporated. The cypherpunks saw this failure and realized that Chaumian eCash had another weakness that had previously gone underappreciated: it relied on a single company. If digital cash were to flourish, it would have to grow beyond dependence on any central party. It would have to become decentralized. Other attempts DigiCash was not the only attempt at creating a digital currency.
The cypherpunks launched many experiments, including Mojo Nation , a payments system for incentivized file sharing, and Hashcash , a "payments" scheme for mitigating email spam. We'll look at Hashcash and implement it ourselves in the cryptography module.
But the cypherpunks weren't the only ones trying to create digital currencies. Founded in , e-gold was one of the first dotcom companies to create a digital currency, two years before PayPal. Credit: netpennystocks. It was immensely popular, but because it had few restrictions on signup, the currency was widely co-opted by hackers, scammers, and organized cybercriminals.
The US government took notice. After a lengthy court case, a court ruled e-gold guilty of money laundering and retroactive violations of money transmitter laws. The founder was found criminally liable, and in , all e-gold balances were frozen. Over the next five years, the US government would manage redemptions of all e-gold account holders.
To the cypherpunks, e-gold demonstrated yet another important lesson: regulators did not want digital cash to exist. The problem with collateral While e-gold was collateralized with gold, DigiCash was collateralized with US dollars. But both ultimately fell within the purview of the state. If you wanted to create a currency that was beyond state control, it seemed that every form of collateral came with a centralization chokepoint.
So maybe, the cypherpunks thought, they should avoid collateral altogether. Was it possible to create a non-collateralized form of money? The US dollar managed to pull it off after Bretton Woods and left behind the gold standard. But if you had a non-collateralized form of money, you also somehow needed to enforce scarcity. Every form of money in the past, whether shells, gold, or US dollars, had some method of ensuring that the money supply didn't inflate out of control.
The cypherpunks explored several schemes for non-collateralized digital currencies. Two of the most important schemes were b-money, described by Wei Dai in , and BitGold, described by Nick Szabo in Both schemes were designed by prominent cypherpunks and were strikingly similar to Bitcoin, but they were both missing key ingredients.
We know that Satoshi was aware of b-money and he cited it in his whitepaper, and he later added an acknowledgement to BitGold on the Bitcoin website.
