    Daniel Roberts (Iris Energy) on Sustainable Bitcoin Mining

    Daniel Roberts (Iris Energy) on Sustainable Bitcoin Mining

    In this latest installment of the mining miniseries, Iris Energy cofounder and co-CEO Daniel Roberts joins us to talk through their approach to mining. In this episode: 
    How Dan came to work in mining Backgrounds of the Iris executive team Which thinkers influenced Dan in his Bitcoin journey Why Iris focuses on sustainable energy and on only entering energy markets where they will not drive prices up for households How Iris chooses geographies to operate How Iris found abundant underutilized power in British Columbia Why Iris’ entry to British Columbia actually drives down energy prices for regular households Why Bitcoin mining has better location agnosticism than aluminum smelting or hydrogen production How Bitcoin miners are more flexible loads than other datacenters How Iris is geographically diversified in Canada, Texas, and Australia, and why geographic diversification is so important How flexibility from Bitcoin mining replaces peaker plants burning fossil fuels Why the oversupply of power is an issue for many power markets Are Western miners being sufficiently responsible in finding low carbon energy sources How Dan thinks about political risk at the state level Can the world accommodate Bitcoin’s power consumption growth if the price goes up tenfold? What plateauing efficiency gains for ASICs means for Iris Why Iris doesn’t see itself as a pseudo Bitcoin ETF and does not seek to hold Bitcoin on its balance sheet Sponsor notes:

    Rep. Tom Emmer (R-MN) on MMT, CBDCs, and crypto policy for 2022

    House Representative Tom Emmer (R-MN) joins the show to share thoughts on his crypto policy agenda for 2022, as well as his views on inflation, MMT, stablecoins, and CBDCs. In this episode: 
    How Rep. Emmer came to be interested in public blockchains Rep. Emmer’s interest in Austrian economics How Rep. Emmer stays up to date with the industry Are MMTers the establishment or an outsider group? Is Washington dominated by covert MMT ideology? Is fiscal conservatism dead in Washington? Why Rep. Emmer voted for the CARES act any regrets he has How the massive injection of cash in the last two years warped our economy Is inflation driven by fiscal spending or corporate greed? Is crypto inherently a partisan issue? Rep Emmer’s concerns about a CBDC Why the US should not take cues from China Why CBDCs are not akin to physical cash Why insisting that stablecoins need bank charters is deeply ironic Problems with the Presidential Working Group’s guidance on stablecoins Is crypto favorable or hostile to American interests? What are Rep Emmer’s colleagues’ residual objections to crypto? The purpose of Emmer’s Securities Clarity Act Will the midterms alter Congress’ approach to the crypto industry? Useful links:

5 star turn up the audio.

Listen to every show. Brilliant. Please turn up the audio level. On full blast I can’t hear the show when I’m driving on the freeway.

Love your monotone gents

New theme song is something this listener would welcome, but not an existential necessity. Between this and uncommon core I think one can have a solid knowledge base.
