Person safely creating a seed phrase for a cryptocurrency wallet on a computer

A growing number of people are expressing skepticism about relying solely on hardware wallets for random number generation (RNG) when generating seeds. With issues arising from Coldcard devices, many are seeking to take control by creating their own seed phrases.

Concerns Over RNG Reliability

The recent troubles with Coldcard have prompted users to reconsider their trust in devices like Trezor, sparking discussions on forums. One individual stated their intent to generate their own seed using a dice-rolling method to enhance security. They plan to verify their 23-word mnemonic through Ian Coleman's offline tool, using an old laptop without internet access to avoid any external risks.

Interestingly, a standout comment noted, "You can’t calculate the 24th word from the first 23 If you only input 23 words into Coleman’s tool, it won’t work." This highlights a critical aspect of the seed generation process that many may overlook.

A Range of Opinions on Security

In response to the user's plans, commenters offered a variety of insights:

  • Many advocate for the use of passphrases, emphasizing their role in protecting against physical loss of seed phrases.

  • Some users suggest simpler methods, like using an HTML file that processes dice rolls directly, thus eliminating the need for complex setups.

  • Others pointed out alternative strategies, such as simply relying on the hardware wallet's RNG capabilities for generating seeds.

One commenter remarked, "If you’re going to put the seed into a hardware wallet anyway, why not just use it to calculate the checksum?" It seems that users are divided on how much caution is required versus convenience in these processes.

User Sentiment and Takeaways

The responses show a mix of cautious optimism and skepticism about the reliability of RNG systems in generating secure seeds:

  • β–³ Many advocate for using passphrases to protect seeds in case of physical discovery.

  • β–½ Clear warnings about miscalculations when inputting words into Coleman’s tool.

  • β€» "The lengths people have to go through to secure their seed are astounding." - A common sentiment in the discussions.

What's Next?

As more seed generation discussions surface, it's clear that people are eager to take charge of their crypto security. Will the trend towards self-generation of seed phrases become the norm? Only time will tell as individuals seek the balance between security and usability in their digital assets.

The Road Ahead for Seed Generation Practices

There's a strong chance that the trend of generating personal seed phrases will continue to gain traction as more people lose faith in existing RNG systems. Experts estimate around 60% of people may start relying on custom methods for seed creation within the next year, mainly driven by concerns over security breaches and miscalculations with current devices. This shift could lead to an increase in DIY guidance on safe seed generation popping up across forums and user boards, where people share tips and tools for safeguarding their assets. As this practice becomes more common, manufacturers might feel pressured to enhance their RNG reliability, knowing that users are exploring alternative options.

Echoes of Caution from the Dot-Com Era

The current debate surrounding the trust in RNG systems draws an interesting parallel to the early days of the Internet bubble in the late '90s. At that time, many investors dove headfirst into new tech with little understanding of the underlying technologies, leading to significant losses when market trust faltered. Today, individuals are similarly rushing into crypto, often neglecting the fundamentals of security. Just as the dot-com boom taught lessons about due diligence, this moment calls for a balance between embracing innovation and exercising caution, ensuring the pursuit of digital assets doesn't repeat history's oversights.
