Self Custody Is Dead. Long Live Self Custody

The Coldcard hack last week dealt a serious blow to a segment of the Bitcoin industry. In its aftermath, a sober reassessment has begun around the practices and assumptions involved in securing bitcoin at the retail level. The full consequences of that reassessment may not be visible for months, but the incident has already sharpened a long-running debate over whether convenience features can ever fully coexist with the threat model self-custody requires.

Some observers are now saying that self-custody is dead. Reports estimate that more than 11,000 bitcoins were moved to custodial exchanges last week as users fled one of the Bitcoin industry’s most popular hardware wallets. The hack remains ongoing, and users can still protect themselves. So far, more than 1,300 bitcoins have been stolen, with some estimates placing the figure as high as 2,000 coins.

Coinkite, along with its outspoken founder NVK, has long held firm views on what it takes to secure bitcoin private keys from hackers. The company’s hardware wallets were airgapped to prevent malware from exfiltrating data through USB cables. They used low-resolution LED screens to avoid the complexity of touchscreens. Coinkite also developed protocols such as BBQR and integrated NFC, allowing data to move between the device and a computer without the two touching or sharing SD cards. The list of deliberately paranoid design choices that made Coldcard iconic is long.

Yet the attackers behind last week’s theft did not rely on anything resembling a modern spy thriller. Instead, they exploited the one feature Coldcard should have had completely locked down: the generation of keys with sufficiently high randomness, or entropy. In practical terms, that means secrets that are mathematically hard to guess. Although the devices were meant to rely on high-quality entropy sources, a firmware bug prevented that from happening, resulting in Bitcoin private keys that were relatively easy to guess. The flaw went undiscovered for years, during which time the product only became more popular.

Despite the loss, which hit a group of Bitcoiners among the most committed to self-custody, many in the industry argue that Bitcoin cannot abandon self-custody and still preserve its integrity. The case for that view is straightforward. Satoshi Nakamoto’s white paper presented Bitcoin as a solution to trusted third parties and intermediaries. It made a forceful case against financial hierarchies, especially in light of the systemic risks exposed by the 2008 financial crisis. Many believe that crisis was never truly left behind and that its effects continue to shape the present.

The argument is often extended further back, to the rise of modern banking and fiat currency. The 6102 executive order signed by President Franklin D. Roosevelt in 1933 led to the confiscation of gold from centralized trusted third parties and private citizens alike. After the order threatened gold owners with heavy fines and jail time if they did not sell their bullion to banks at $20.67 per ounce, $300,000,000 in gold was returned. More than 14 million troy ounces were turned in as a result. Another 200 million troy ounces are estimated to have been held in the American banking system at the time. The banking system, in the United States and globally, was built on the gold standard.

The U.S. was then the world’s largest economy and held the greatest concentration of gold within its borders. Its abandonment of the gold standard was seen by critics as a decisive break for gold as a free-market pricing mechanism for goods and services. Governments around the world, now freed from the constraints of sound money, were said to have benefited from inflation. At the time of the executive order, gold was fixed at $20.67 an ounce; less than a year later, it was repriced to $35 under the Gold Reserve Act of 1934, a 69% devaluation of the dollar.

In this view, the fiat standard was handed to governments by an alliance between the banking system and politicians. It gave central banks the legal power to create money at will. World War Two followed, funded by fiat currency, and tens of millions of people were sacrificed in the conflict.

A century later, U.S. government debt requires almost a trillion dollars a year in interest payments alone, with total debt close to 40 trillion and debt-to-GDP at 123%. Supporters of this argument say those are predictable consequences of the end of the gold standard. They also point to the collapse in the dollar’s purchasing power over the past century, even as technology has delivered dramatic gains in efficiency. In their view, that outcome is only possible under money that has steadily lost value for decades. By this standard, the dollar is still the strongest of the fiat currencies.

The confiscation of gold in a rising power like the United States effectively killed the gold standard. But advocates of Bitcoin argue that such a move would have been far harder if civilian custody of gold had been broader and more distributed. Many of the civilians who returned millions in gold after the 6102 executive order had taken it out of their bank accounts during a bank run. Their names and the amounts they held were known and tallied. If gold had been easier to move in large quantities, or if private ownership totals had been more ambiguous, then the state might not have been able to shut down the free flow of gold so easily by leaning on bankers. In that case, the world’s economies may not have been able to absorb such a vast and destructive war as World War Two in the following decade.

Bitcoin Is Gold, Engineered to Survive a 6102 EO

Bitcoin is presented as an alternative to gold designed to learn from gold’s weaknesses. It has properties that make it better suited to resist confiscation and survive state pressure. Bitcoiners envision a world in which Bitcoin becomes a global monetary standard, with a large minority or even a small majority of the global economy using it as their primary store of value. In that future, Bitcoin would replace gold and restore sound money to the capitalist order.

For Bitcoin to become a global reserve currency and defend that position, it must be better than gold. Advocates say it can be, precisely because it is digital. Private key control, even after the Coldcard hack, can be more powerful than any physical vault. Multi-signature scripts enable distributed storage of Bitcoin private keys, requiring a threshold of approvals before coins can move. That makes it possible to build multi-jurisdictional, multinational vaults that could resist a large state attempting a new kind of 6102-style takeover.

Bitcoin’s digital design also allows large amounts of value to be moved easily, without sending the navy to collect gold or building a hierarchy of banking custodians to transfer it. With tools available today, and better tools still to come, civilians may be able to conceal Bitcoin ownership, as has already been done in war-torn countries such as Ukraine, and thereby escape a hostile state’s control over public wealth.

Ultimately, a major hardware wallet manufacturer has failed the Bitcoin industry. But the fundamental qualities of money, as identified by Aristotle and others, remain unchanged, and Bitcoin is still presented by its supporters as the strongest of the three: Bitcoin, gold, and fiat.
