That’s kinda the point - this is how traditional media covered a simple story. I should add or even write a detailed one with proper coverage.

Thanks for the feedback!

🕰️ 'Moscow Time' Meme is Born | March 25, 2021

During a congressional hearing, Jack Dorsey's Blockclock Mini, displaying the sats/USD rate, sparked confusion in the normieland. Cybersecurity analyst Chris Vickery mistakenly claimed it showed Moscow time, fueling conspiracy theories. Bitcoiners embraced the term 'Moscow Time' as shorthand for the sat/USD conversion rate: the lower it is, the stronger Bitcoin's purchasing power. When 00:00 strikes, it's hyperbitcoinization time, baby.

Timothy C. May responds to a Cypherpunks mailing list discussion on digital cash, highlighting double-spending as a critical challenge. He proposes online clearing and blinding protocols as potential solutions, though neither fully resolves the issue.

📑 Bitcoin-dev Archives |March 24, 2017

In this email thread, developers explored mining centralization risks, debating empty block attacks and the declining role of independent full nodes.

While the issue remains open, discussions like these drive Bitcoin's continuous evolution. https://gnusha.org/pi/bitcoindev/5b9ba6c4-6d8f-9c0b-2420-2be6c30f87b5@cannon-ciota.info/

If only we had a way to to authenticate users via a private-public key cryptography 🔐

Maybe looking into history could help us find the solution.

Nixon shock

08-15-1971 | An end to convertibility of US dollar into gold

Nixon directed Treasury Secretary Connally to suspend, with certain exceptions, the convertibility of the dollar into gold or other reserve assets, ordering the gold window to be closed such that foreign governments could no longer exchange their dollars for gold. This marked the initial step towards a detrimental fiat system that saps our time and diminishes the worth of our work and savings.

The detrimental consequences of unlinking currencies from gold are vividly portrayed at https://wtfhappenedin1971.com/.

08-01-2017 | Bitcoin Independence Day

Today bitcoiners are celebrating Bitcoin Independence Day. This holiday is the culmination of a two-year war between two camps within the Bitcoin community, defending their vision of how to approach protocol scaling.

Today, in 2017 the UASF softfork was activated, marking the control of users (rather than miners and corporations) over the Bitcoin protocol. Spare 6 minutes to watch this short video by Aaron van Wirdum, where he explains what UASF is and why this softfork is so important to the Bitcoin community and the further development of the protocol.

You can learn more about Bitcoin's Block Size War and the events leading up to UASF from Jonathan Beer's book: https://blog.bitmex.com/the-blocksize-war-chapter-1-first-strike/

Test post at BitMeet Nostr Community with satellite.earth. A curated community to share upcoming Bitcoin & Nostr meetups, events and conferences.

Exactly one year ago, Salvadoran students received their first diplomas for completing the 10-week Bitcoin course. The program introduced the children to the theoretical and practical aspects of Bitcoin and the Lightning Network.

“In 2021 we taught 400 students in San Salvador, in 2022 we expanded to 12 of the nation’s 14 departments, in March 2023 alone we taught over 5,400 new students.”

It's back! Sorry - got carried away by so much stuff. Now that I'm concentrated on nostr:npub10eezfnlq4ad2lyf3478na8f5las4l7guuf55vs8378lwtk87hd7slf6zka it is obvious that the calendar will be a nice parallel project to accompany a news resource.
