Bitcoin’s block rewards are shrinking. Security depends on fees which means higher economic density per block. Portal is building BTCFi so Bitcoin becomes the settlement layer for all markets. Listen to our CEO explain below 👇

"I used to be a bitcoiner. The transition to a new store of value only happens once every 3,000 years. That's the main prize -- just focus on that. But [security] is the criteria that ultimately convinced me to flip from Bitcoin to ETH." "I have a higher degree of certainty that Ethereum will be around longer [than Bitcoin]. The reason for that is because Bitcoin relies on proof-of-work, which is less efficient than proof-of-stake and doesn't scale with the value of the network. And as the block subsidy of Bitcoin halves every four years, it is increasingly becoming more and more reliant on transaction fees to fund the security budget paid to miners." "If you look at [Bitcoin's] security budget right now, about 0.6% of revenue to miners is transaction fees... The problem with that is if Bitcoin becomes 'digital gold', flips gold, and becomes a $30 trillion asset, but it only costs $10-20 billion to attack it, that's too asymmetric." "You want the security budget to scale with the market cap, similar to how countries spend a % of their GDP on defense. The more valuable something is, the more you need to spend to protect it." "Ethereum, with the Merge, migrated to proof-of-stake, which is fundamentally more secure because it's less reliant on transaction fees and it scales with the value of the network. If 1/3rd of ETH is staked and then you need 1/3rd of those ETH to censor the network, you're looking at roughly 10% of the total market cap as the cost to attack the network." "So if Ethereum flips Bitcoin and gold and becomes a $30 trillion asset, it'll cost ~$3 trillion to attack the Ethereum network versus Bitcoin at like $10 billion." "The other aspect here is that as AI hyperscalers invest more and more in AI, proof-of-work becomes increasingly vulnerable because the cost to attack the Bitcoin network is starting to look close to the quarterly CapEx these hyperscalers are spending on their data centers."

BITCOIN RAILS #34: Bitcoin’s Security & Quantum Risks—and the Future of Satoshi’s Coins | with Jameson Lopp Jameson Lopp “Most people don’t think about security until it’s too late,” says the Casa co-founder and CSO. One of the most prolific thought-leaders in Bitcoin security and privacy, there are few people who understand the nuances of Bitcoin security quite as deeply - not to mention the OPSEC practices required to protect against wrench attacks, for instance, which are rising globally as Bitcoin price increases. More recently, Lopp has turned his attention to mitigating Bitcoin’s quantum vulnerabilities, including market risks associated with quantum-vulnerable Satoshi’s Coins + longer-term strategies for quantum-hardening of Bitcoin addresses long term. In this special episode of Bitcoin Rails, we cover: - Lopp’s experiences designing self-custody products at both BitGo and Casa - The swatting attack he suffered in 2017, and the radical steps he’s taken to secure his home location since - The ‘quantum computing’ challenge for Bitcoin and its impacts on Satoshi’s Coins - How the network may respond to QCs in the face of ossification and why QC preparation may be the hardest governance test the network has ever faced This episode is powered by: - Best In Slot (Best in Slot | BRC2.0 🧑‍🍳), the leading API for Ordinals and BRC20 data aggregation and indexing - Spark (Lightspark), a statechains implementation leading the path towards institutional adoption of Bitcoin-powered payments - Citrea (Citrea), the leading Bitcoin Rollup technology and contributor to the BitVM alliance 📌 Timestamps 00:00 – Intro: Quantum Computing Meets Bitcoin 00:19 – Jameson Lopp on the Bitcoin Rails 00:53 – The Quantum Threat to Bitcoin Security 06:32 – Lopp’s Path into Bitcoin & Security 12:58 – The Swatting Attack During the Block Size Wars 25:28 – Could Quantum Crack Satoshi’s Coins? 43:55 – Announcements & Sponsors Messages 45:30 – Building Bitcoin’s Quantum Resistance 47:00 – QBTC and the Push for Quantum-Resistant Bitcoin 48:43 – Why Changing Bitcoin Is So Hard 51:19 – Email Protocols, Ossification, and Bitcoin’s Future 01:01:53 – A Roadmap for Quantum Resistance
