My talk from btc earlier this year is up here for you all to enjoy 💅💅
Optimistic execution of RISC-V in Tapscript by Johan T. Halseth. This presentation was recorded in May 2024 in Austin, TX during bitcoin conference, script edition. Watch now: buff.ly/4foP1u5 If it compiles, it can be verified in Bitcoin script. We'll show how a covenant addition to Bitcoin could power up Tapscript to enable verification of arbitrary computation, and other good stuff. #btcplusplus #devconf #bitcoineducation #bitcoinconf #bitcoindev Sign up for one of our upcoming dev conf at btcpp.dev - Florianopolis, Brasil | Feb 19 - 22, 2025: buff.ly/3C6hhU4 - Austin, Texas | May 7 - 9, 2025: buff.ly/3YizbKE

Dette er den harde realiteten av å være gründer. Du kan på kort tid miste hele livsverket ditt. Tenk om Karl hadde flyttet til utlandet da papirverdien av hans Oda-aksjer var verdt flere hundre millioner. Han ville fått en betydelig exit-skatt, og deretter blitt kalt inn til en generalforsamling hvor han opplever at verdiene hans praktisk talt nå er satt til null. Skatteregningen på flere titalls millioner ville fortsatt bestått. At både formuesskatt og exit-skatt er en realitet i Norge, er helt sjukt. Håper @kariekas , @SVparti, @Arbeiderpartiet, @Senterpartiet og resten av venstresiden nå forstår hva vi mener med papirverdi og arbeidende kapital.

NORWAY IS GOING TO BAN BITCOIN MINING WITHOUT PUBLIC CONSULTATIONS - WE NEED TO ACT NOW Norway's Ministry of Digitalisation and Public Administration responded to @ODFoundation that it "has no plans to conduct a public consultation" on a ban on cryptocurrency mining. There is no doubt that the ban designed to target #Bitcoin mining. Unfortunately, that's a stance of the @Stortinget and the Norwegian government. stortinget.no/no/Saker-og-pu… 🔴 Why we should protect our #freedomtech Bitcoin in #Norway NOW: (1) Norway is fully integrated in the European Single Market throught the European Economic Area (EEA) and Schengen Agreement. It means Norway can provide its legilsative approach as an input for new legislation for the EU/EEA both: - during the preparatory phase, when the @EU_Commission is developing proposals; - during work of expert groups and committees of the European Commission; - submitting proposals and comments to European Free Trade Association on upcoming legislation. (2) As a co-founder of the @OECD , Norway sets an example of regulation worldwide and provides its legislative recommedations for global standards. (3) Norway has historically been a place to meet, share experiences and educate human rights defenders and bitcoiners from around the world. Norwegian goverment will present its investigation a ban on cryptocurrency mining by the end od 2024. 🔴 What we should do together to prevent Bitcoin mining ban: (1) Repost this post and join our #BTC Coalition to educate local communities and media about social benefits of Bitcoin mining in Norway and worldwide; (2) Help us pool resources and best practices to convince Norwegian politicians and media to explore the social benefits of Bitcoin to prevent this repressive regulation; (3) If you are a Norwegian citizen: write a letter to your legislator and government asking for public consultation and providing arguments about the social benefits of Bitcoin mining for Norway. 🧡

There's been a lot of excitement around new #Bitcoin layer-2s and off-chain protocols lately. Kicked off by the Taproot upgrade and entering full force with MATT and BitVM, several promising protocols are being developed 🔧 (Thread on protocols and a ZK verifier demo🧵)

Here's an example of using Elftrace to compile the Winterfell ZK-STARK verifier to Bitcoin Script and use it to verify-the-verification of a STARK: github.com/halseth/elftrace/…

And with BitVM being heavily researched, maybe we can get close to this dream even without a script upgrade? 🤯 x.com/johanth/status/1712061…

There has been a lot of excitement around BitVM the last couple of days. We all believed arbitrary computation on #Bitcoin needed a script upgrade, so how can BitVM achieve this without a consensus change? 🧵👇 x.com/robin_linus/status/171…

Finally some drama! @reardencode thinks CAT scripts are ugly, and that combining CAT with CCV could be a great idea since truly building useful things with CCV requires CAT. @rot13maxi puts on a brave face behind his shades, but the audience can tell he is hurt.

Storbonden får 99 % formueskjerming på gården. Kan den ikke verdsettes til virkelig verdi, så kan jo bare bonden selge litt av gården for å betale skatt? Dette er vel svaret som blir gitt til alle andre som driver næring. finansavisen.no/finans/2024/…

Looking forward to visiting Austin in May!
@johanth presents Optimistic execution of RISC-V in Tapscript, a visionary look at how Bitcoin could verify arbitrary computation, opening new avenues for script flexibility and power.

The Norwegian government is killing their startup scene. The tax system was already bad enough for entrepreneurs, but now they’re taking it even further. If you leave the country having raised money for your startup, you’ll now have to pay an exit tax of >30% of your startup’s valuation - even if you never got a dollar out of the startup personally! Imagine a co-founder owning 30% of their $10m seed startup. They’d have to pay $1m in taxes if they leave the country. And it’ll only get worse as you raise later rounds. As a consequence, you’ll be kept hostage as a founder in Norway. It’s effectively becoming the Cuba of the Nordics. It’s especially sad given that Norway’s economy is extremely reliant on fossil fuels - and entrepreneurs are the only way to diversify the economy. The message here is clear: If you’re about to found a startup in Norway, make sure you move first.

Is @ecb secretly following the resurgence of OP_CAT??? cc @Arminsdev @Ethan_Heilman
Bitcoin has failed to become a global decentralised digital currency, instead falling victim to fraud and manipulation. The recent approval of an ETF doesn’t change the fact that Bitcoin is costly, slow and inconvenient, argues #TheECBBlog ecb.europa.eu/press/blog/dat…
Community note
Chainalysis found that only 0.34% of the transaction volume with cryptocurrencies in 2023 was attributable to criminal activity. Bitcoin's share of this is significantly lower with 25%. Illicit transactions with Euros accounted for 1% of the EU's GDP or €110 billion in 2010. chainalysis.com/blog/2024-cryp… transparency.eu/priority/finan…
