About This Episode
Blockchain and cryptocurrency have been wrapped in hype, speculation, and myth for years. But beneath the noise lies a more interesting question: what is blockchain actually doing, and when does it matter? In this episode, Mikkel Svold sits down with Rasmus Risager Lindegaard, product manager of the Grow Colony at Lunar (a Danish digital bank), to cut through the confusion. They explore blockchain not as a revolutionary technology that will replace banking, but as a database innovation that solves specific problems in specific contexts. The conversation moves methodically from first principles. Consensus mechanisms, proof of work versus proof of stake, the double spend problem appear alongside real-world adoption patterns that look remarkably different depending on where you are. In Nigeria or the Philippines, crypto adoption is not a curiosity. It is a rational financial tool. In the Nordic countries, it remains niche. That gap between speculation and utility is the real story of blockchain's future.
Rasmus brings the perspective of someone who has to make practical product decisions about how Lunar engages with blockchain, not someone selling you on a vision. He has watched the conversation shift from "cryptocurrency will replace banks" to "how do we use blockchain for specific financial problems?" This episode is essential listening for anyone who wants to move past the headlines and understand what blockchain actually is, what it can do, and where the real opportunities and genuine drawbacks actually sit.
In This Episode
- How blockchain differs from traditional databases and why distributed consensus replaces central authority
- Why proof of work functions as a race and proof of stake functions as a lottery, and what that means for energy use
- How Bitcoin achieved its goal of creating money outside central authority, then failed as a payment system because it became too valuable to spend
- Why less than 1% of blockchain transactions are linked to crime, compared to 2-5% for traditional money
- Global adoption patterns that reveal where crypto actually solves real problems: 30% in Nigeria, 6-14% in the Nordics
- Remittance costs, play-to-earn economies, and the concrete ways blockchain is already changing lives in developing countries
- What decentralized finance looks like when you remove the central bank entirely
Key Quotes
"The word has been used so much in recent years that it kind of means nothing at this point. People, oh, blockchain, yeah, that's this amazing magical technology almost. But I think when you boil it down, blockchain is a database technology, that's it."
"Bitcoin was created with the express purpose of being a form of payment, right. But it became such an investment in and of itself, it has failed in actually becoming an efficient means of payment."
"If you look today at Chainalysis, a blockchain analysis firm, they estimate it's a really low amount of percentage of blockchain transactions that are expected to be related to crime in one way or another. Now, it used to be around 30%, but now it's down to essentially 1%."
"There are pockets where this is already mainstream and where it is already well known. And you also have examples such as Axie Infinity, which is a sort of play-to-earn game also based on blockchain technology and cryptocurrencies, which meant that you could actually statistically see in the Philippines, men's income relative to women's was increasing because they were all playing this game and actually earning crypto."
