Hi Everyone,

I have a couple of follow-ups to Bitmark’s recent milestones mentioned in past newsletters.

Last week, our team received the Cohack award for Autonomy, our public health app. Taiwan president 蔡英文 Tsai Ing-wen presented CEO Sean with the award, which upon seeing up-close photos of, I’m quite envious.

See Sean at :15 from this tweet from the President.

We also officially announced our collaboration with UC Berkeley and its school of public health via this press release. We’re excited to transition Autonomy to the…

Hi Everyone,

It’s been a stressful few weeks to start November for the United States. First, the election, to which some claim is not over. Then, the rampaging COVID outbreak, to which some act as if public health is not a big deal.

I won’t say more.

Instead, I’d like to highlight our team’s recent work on the Hope in Crisis Podcast, a collaboration with Girls in Tech, a global non-profit organization focused on the engagement, education, and empowerment of women in technology.

As the Bitmark blockchain becomes more popular for NFTs, health data, music royalties and other types of digital property, we are frequently asked about the energy impact of the Bitmark blockchain and of blockchains in general.

Energy & The Blockchain

The energy usage of blockchains has been in the news a lot lately. What’s that about?

Q: Why do Blockchains Use Energy?

A: The most widely used methodology for securing blockchains is the “proof-of-work” algorithm, which is at the heart of Bitcoin, as well as the Bitmark blockchain.This means that you have to do work in the form of extensive cryptographic…

Hi Everyone,

A major discussion we’ve been continuing internally is about how Bitmark can make the control of digital rights accessible (applicable) to everyone. As hard as we’ve worked in the areas of personal data, healthcare, music, and art, there remains a significant learning curve for most people to join in. Many of us in the United States are used to signing our rights away without really considering what we’re reading. That’s the way it is.

If you’re now told you should have better control over your rights and this…

Dear Investors & Advisors

Bitcoin appears to be emerging from the trough of despair. The fundamentals are looking strong. Taproot, one of the most important improvements to the Core Protocol, was merged. That will enable more flexible (and private) smart contracts when activated. Or price, if that’s your signal, is again back to nosebleed levels. When…

Observations (from the future)

This is a letter from the future. It’s August of 2021 and even though we do have a vaccine, it’s not widespread. IP disputes between the US, Germany, and China (all contesting patents) are holding back deployment while the pandemic continues to punish society. But there is some…

At Bitmark, we believe that agreements around digital property (data, artwork, collectibles) cannot be resolved purely through traditional legal contracts or technology-based smart contracts. Legal contracts can’t handle the fidelity of digital assets (such as defining and enforcing the boundaries of digital property) at scale, technology-based smart contracts can’t handle the incomplete nature of contracts. No contract, and thus no…

In the last few years, headlines have blared that Bitcoin has grotesque energy costs. The Bitcoin Energy Consumption Index (Footnote 1) currently estimates 78 TWh a year. More importantly, in these years of climate change, which is a real, global crisis, they note a carbon footprint of 37 Mt CO2. The sensationalist headlines usually note that this is the same as New Zealand.

Though these numbers may be technically correct, that’s the worst type of correct, because the headlines are pure clickbait. They create outrage without offering context and in doing so create a false impression. …


This is the transcript of Hope in Crisis, a podcast series about rights and democracy and how technology enable or disable it. In this episode we will learn about how democracy is dismantling under the combination of authoritarian and big tech companies, and most importantly, how Hong Konger and the rest of the world can see hope in this crisis.

Dear Investors & Advisors

I can still clearly remember that sinking feeling, riding the bus from Niseko to the Sapporo airport, after reading the Wuhan Coronavirus Wikipedia page. This was mid-February.

Wikipedia is my filter for fake news. In this specific case, my aim was to disprove the wife. She wanted me to wear a mask…
