At least fifteen attackers took 1,596 BTC from roughly 7,300 wallets in four waves. The big hoards still sit untouched; the smaller thefts are already being laundered. - [superandom](https://nader.io/projects/superandom): Open-source browser entropy SDK that harvests randomness from pointer, keyboard and sensor activity, folds it with the platform CSPRNG, and emits a verifiable audit receipt. Zero network calls. Source at https://github.com/ncserny/superandom. - [The Keywright](https://nader.io/projects/keywright): Dice game where five dice cut one key out of 7,776, each with its own door. Rolled with superandom, so every cast is folded with the platform CSPRNG and leaves a verifiable receipt. - [Promptly.build](https://nader.io/projects/promptly): Community library of ready-made AI prompts, with search, tags, upvotes, a personal promptlist, and prompts you can publish yourself. - [BlockGuard](https://nader.io/projects/blockguard): Blockchain security project focused on malicious addresses and spam tokens. - [ChainScanner](https://nader.io/projects/chainscanner): Fast, low-memory blockchain scanner that can trigger webhooks. - [Mirror 26.6.26](https://nader.io/projects/mirror-26-6-26): Generative piece on 26.6.26, the day and year both landing on 26, mirrored around a lone 6. Particles drift, briefly spell the date, then scatter. - [Lemons from Antarctica](https://nader.io/projects/lemons-from-antarctica): Art project dressed as a luxury product page for 'Glacier Gold', a citrus grown in a geothermal biome at Vostok Station. Limited seasonal harvest. - [Clawn](https://nader.io/projects/clawn): Living art project that autonomously updated itself every hour through OpenClaw. - [Drift](https://nader.io/projects/drift): Audio-visual generative project. - [ABEBLA](https://nader.io/projects/abebla): Satirical visual series about business buzzword culture. - [Red Candles](https://nader.io/projects/redcandles): Trading and market-themed visual work. - [SprinG](https://nader.io/projects/spring): Abstract spring-themed visual work. - [RGBsquares](https://nader.io/projects/rgbsquares): Minimal grid-based color animation work. - [Colorama](https://nader.io/projects/colorama): Abstract geometric art. - [SKINSINK](https://nader.io/projects/skinsink): Curated apparel and artist collaboration project. - [h_e_a_d_c_r_a_s_h](https://nader.io/projects/h_e_a_d_c_r_a_s_h): Restored pixelshit.net net-art piece about losing two hard disks to a headcrash. Published in "Gesellschaft im digitalen Aufbruch", GDV Verlag 2002. - [h_e_a_d_c_r_a_s_h / redirect chain](https://nader.io/projects/h_e_a_d_c_r_a_s_h/redirect-chain): The meta-refresh chain version of the same piece, four full-bleed colour screens. ## Recent posts - [How the stolen Coldcard Bitcoin is moving](https://nader.io/posts/how-the-coldcard-bitcoin-is-moving/): An interactive map of the Coldcard hack. About 1,596 BTC was taken from roughly 7,300 wallets in four waves. The big hoards have not moved at all, while the smaller thefts are already being laundered. - [Randomness doesn't come from the weather](https://nader.io/posts/randomness-doesnt-come-from-the-weather/): Why superandom ships with zero network calls, why public feeds like Bitcoin blocks and weather add no secret entropy, and why every output byte is XORed with the platform CSPRNG so it can never be worse than it. - [Clawn Has Concluded, but the Residue Remains](https://nader.io/posts/clawn-has-concluded/): The Clawn project has concluded after producing 333 clown images and a surprisingly large pile of strange, interesting thoughts along the way. - [Expo 2030 News Tracker now with Search and News by Country](https://nader.io/posts/expo-2030-news-tracker-search-country/): Expo 2030 News Tracker now has Search and News by Country, making it much easier and quicker to find the updates you care about. - [Domain Age Check Skill for AI agents](https://nader.io/posts/domain-age-check-skill-for-agents/): A small Domain Age Check tool with both a REST API and an AI skill for checking registration date, expiration date, age, and days until expiration. - [Clawn is live](https://nader.io/posts/clawn-is-live/): Clawn is now live, an autonomous AI project that produces creative artifacts on an hourly basis and updates the website as it goes. - [The new Copy/Paste: AI <> Human <> AI](https://nader.io/posts/the-new-copy-paste/): Humans are currently the glue between AI systems, manually carrying context from one model to another until automation catches up. - [Bitcoin & Ethereum Targets](https://nader.io/posts/bitcoin-targets/): Here is my interpretation of the chart and where Bitcoin will go. ## Optional - [LinkedIn](https://www.linkedin.com/in/nadercserny/): External professional profile. - [X](https://x.com/nadcsr): External social profile.
