EntropyLab had a pile of updates in the last 24 hours. Here are couple I'm most excited about PSBT editor now draws the spend like mempool does.. one box per input, one box per output. Amount. Address. Signed or not. Tap a box, edit that field. rust bitcoin checks the file before it hands it back. Global sync is in too. One checkbox, off by default. Turn it on and the lab keeps dice, cards, number bases, seed words, and keys talking to each other as you type. Enough bits land, the next character appears. Hashed inputs can fill the rest. Edits in the other direction never overwrite a hashed source. This one is my favorite.. Vanity grinding should merge later today. Same offline HTML file. You pick a prefix. The lab walks the keyspace on CPU, or GPU if the browser has WebGPU. Regular addresses and Silent Payments. Default is a calculator: hash a salt, add a counter, same salt always replays the same key. No RNG for the private key. Nothing leaves the page. Don't ever use it for real Bitcoin. Educational purpose only!

One week old today. What EntropyLab already did: • Dice, coins, cards, hex, or binary → seed • Dice methods: hash the rolls, BitBox-style, Ian Coleman / Keystone, D++ D8/D16 • Live die-fairness check while you enter rolls • Seed phrase, xprv/xpub, WIF, hex key, Casascius minikey • Optional passphrase • All five BIP39 lengths: 12, 15, 18, 21, 24 • BIP39 seed, xpubs, fingerprints, descriptors, Bitcoin Core wallet.dat export • LifeHash next to each fingerprint so two keys are not easy to mix up • Legacy, nested SegWit, native SegWit, Taproot • Mainnet and testnet • Watch-only multisig from xpubs. No private keys required • Recovery sheet you can save or print • PSBT inspect: where it sends, amounts, fee, signed or not • Same inspector accepts a fully signed raw transaction • Labels outputs as change, receive, or not in this wallet when a session key is loaded • Finds inscription envelopes in tap-leaf scripts and witnesses (`OP_FALSE OP_IF "ord"`). Reports content-type, size, and a text preview. It does not number sats, fetch the chain, create inscriptions, or render images. • ECDSA nonce reuse check • Optional RFC 6979 check with a key that stays in RAM for that session only • Jade anti-exfil transcript check without a key What we added in the last two days: • BIP-85 child entropy from the parent you supply. Same parent, application, and index always reproduce the same child. Matches COLDCARD. Calculator, not a generator. • Silent Payments (BIP-352): reusable `sp1q` / `tsp1q` addresses, labeled codes, BIP-392 `spscan` / `spspend` descriptors, sender taproot outputs from pasted vin JSON, receiver check of pasted x-only outputs. It does not connect to a node or scan the chain. • Decodes OP_RETURN size and a text/hex preview. It does not create OP_RETURN outputs. • All Bitcoin math now runs on rust-bitcoin in WASM. Same library family Bitcoin Core uses. The HTML no longer ships a JS crypto stack. It still does not generate entropy. • Real PSBT editor. Open a PSBT, see every field, change a field, export only if rust-bitcoin accepts the file. It does not sign. It does not go online. • Pick the derivation scheme instead of hoping the tool guessed BIP84. BIP44 / 49 / 84 / 86 / 48, or type the path yourself. • PSBT inspect now reads Taproot script-path spends, UR crypto-psbt payloads, BitBox anti-klepto transcripts (not Jade), and reused Schnorr nonces. Reused nonce is the alarm. RFC 6979 mismatch is not. • Taproot multisig starts on BIP87, the co-signer account standard — not BIP86. A pasted BIP87 xpub no longer silently flips you to legacy P2SH. • After it is done with a seed or key, it wipes those buffers. Strings in the page are still strings. Download the file. Verify it. Open it on a machine that never goes online. This tool is for a Bitcoin power user which was only possible because of token maxen. #OogaBooga#

I told you so. December 18, 2023: "You can fire the miners by choosing a different pow algorithm." January 14, 2024: "You can't 'fire the miners.' You can create a new network with different miners." October 14, 2024: "Who's saying fire the miners? Lol, that's an idiotic take. Firing miners gives us an airdrop." May 6, 2025: "It's going to get merged. Luke is going to advocate for a PoW change (again)... It's one big nothing burger." June 9, 2025: "First part done. 2nd part might not happen because Luke cucked himself with sha256 miners employing him." June 11, 2025: "Luke's livelihood relies on sha256 miners now." September 23, 2025: "he can't 'fire the miners' anymore because he relies on sha256 miners for income. So basically nothing happens." August 10, 2026: "Uno reverse. The 2nd part is happening. Luke is no longer being employed by sha256 miners." And Luke's latest, August 29: "OCEAN and Luke Dashjr announce today that, by mutual agreement, Luke Dashjr has separated from OCEAN, resigning as Chairman, Chief Technology Officer, and director."

@btcpavao @brian_trollz One more note.. With high entropy passphrase there is no need for steel. You can make many backups of the seed. You're not worried about the bank raiding your deposit box because you know the passphrase has as much entropy as the seed.

Didn't think about adding this when I started EntropyLab. Rob Hamilton and Shinobi convinced me. Now it's the feature I like the most. Read a PSBT. Check its ECDSA nonces. No key required for inspect-only.

These are purely tokens.. The investment he made into altcoin companies is even worse than this... But at least the gen pop doesn't get rekt with those directly. BOB (Build on Bitcoin): Castle Island invested (multiple rounds including seed/strategic). Token launched, hit ATH around $0.029 in late 2025, now trading ~$0.004 range → roughly 86% drawdown from peak. Lags BTC hard over the period. Babylon (BABY): Castle Island portfolio company. Token ATH ~$0.17 (April 2025), now ~$0.012 → ~92% drawdown. Significant underperformance vs Bitcoin. STFX: Confirmed seed (July 2022). Near-total wipeout (~99%+ from ATH). Moonwalk Fitness (MF): Nic Carter listed as investor in the Oct 2024 seed. Token down ~90%+ from peak. Ethena (ENA): Appears in lists tied to him/Castle Island involvement in the extended seed. Deep drawdowns from its ~$1.50 ATH (multiple 80-90%+ periods).
