For years, Bitcoin in Ireland has quietly simmered at the grassroots level—discussed in pubs and meetups, debated in Telegram groups, and occasionally splashed across headlines with predictable suspicion. But recently, the temperature is beginning to rise. With the release of “A Sound Punt: The Case for Ireland’s Interest in Bitcoin” by Bitcoin Network Ireland (BNI), and a weekend that sees both the Bitcoin Ireland Conference and Aontú’s Ard Fheis, it’s clear momentum is building on the Emerald Isle.

A Sound Punt: A Paper for the Citizens of Ireland

The new paper, released today by Bitcoin Network Ireland, is a concise, accessible document crafted to cut through the noise…

In the last Mempool article, I went over the different kinds of relay policy filters, why they exist, and the incentives that ultimately decide how effective each class of filter is at preventing the confirmation of different classes of transactions. In this piece I’ll be looking at the dynamics of the relay network when some nodes on the network are running different relay policies compared to other nodes. 

All else being equal, when nodes on the network are running homogenous relay policies in their mempools, all transactions should propagate across the entire network given that they pay the minimum feerate necessary not to be evicted from a node’s mempool during times of large…

Medical equipment provider Semler Scientific has acquired 455 Bitcoin for $50 million, marking it one of the largest purchases as more publicly traded companies continue to adopt Bitcoin treasury strategies.

After a volatile start to 2025, Bitcoin has now reclaimed the $100,000 mark, setting a new all-time high and injecting renewed confidence into the market. But as prices soar, a critical question arises: are some of Bitcoin’s most experienced and successful holders, the long-term investors, starting to sell?

George Town, Grand Cayman — Ledn, one of the longest-standing digital asset lenders, today announced a sweeping update to its platform to discontinue any lending of client assets to generate interest, meaning that client assets will never be exposed to third party lending credit risk.

Going forward, Ledn will only offer its Custodied Bitcoin loan structure, under which client bitcoin collateral will remain fully in custody either with Ledn or its trusted funding partners.

As part of this strategic shift, Ledn will also remove support for ETH, doubling down on Bitcoin as its sole digital asset focus. These changes were unveiled by the company at Bitcoin 2025 in Las… Read more on bitcoinnews

My latest painting, The Citadel (v. Nardo), did not begin simply on canvas. It began as a whisper – an image passed digitally between anonymous hands, reposted, remixed, archived, and mythologized across the internet. Like many of my works, this piece builds from historical fragments and symbols, grounded in the belief that memes are not fleeting – they are foundational. They don’t just reflect culture, rather, they write it.

Last year in 2024, I presented a solo show in Abu Dhabi centered around the fact that Subway – the sandwich chain – was one of the first fast food restaurants to accept Bitcoin. That small historical detail became the seed of a larger conceptual…
