I cannot write code, but I can make judgments, so I split those two apart and cleared three problems on the way to a blog that finally fits. aithoughts https://wb3vb.com/en/2026/07/npm-debut https://wb3vb.com/en/2026/07/npm-debut Sat, 25 Jul 2026 23:15:00 GMT I got all the way to npm chasing a one-line install, and then an independent audit scored it 42.7 out of 100. Here is the two-month report card and the nine things left to fix, in priority order. aisecond brain https://wb3vb.com/en/2026/07/how-i-use-my-brain https://wb3vb.com/en/2026/07/how-i-use-my-brain Tue, 21 Jul 2026 07:50:00 GMT I asked for a deck and got back more than I asked for, because it had pulled old meetings and past decisions out of the brain. Records compound. Past the two-month mark, output quality is decided by what has accumulated rather than by the prompt. aisecond brain https://wb3vb.com/en/2026/07/apartment-area-terms https://wb3vb.com/en/2026/07/apartment-area-terms Mon, 20 Jul 2026 10:00:00 GMT One unit has several sizes because each counts a different boundary. Exclusive area first, shared space layered on, applied to the 84㎡ standard and Olympic Family Town. real estate https://wb3vb.com/en/2026/07/neurain-haedogbeob https://wb3vb.com/en/2026/07/neurain-haedogbeob Thu, 09 Jul 2026 13:30:00 GMT The system is called Neurain. Split it into three parts, knowledge, operating rules, and a swappable AI host, and the structure snaps into focus. I took apart nineteen comparable products, and here is what I copied, what I refused, and what moat is left. aisecond brain https://wb3vb.com/en/2026/07/second-brain-anatomy https://wb3vb.com/en/2026/07/second-brain-anatomy Mon, 06 Jul 2026 21:05:00 GMT Ask one question and search runs four stages over three seconds. Split the words and widen them with synonyms, pull candidates from 4,700 documents, filter down to real evidence, then compose the answer on top of it. Answer quality is decided by the evidence, not the model. aisecond brain https://wb3vb.com/en/2026/06/518-commits-zero-code https://wb3vb.com/en/2026/06/518-commits-zero-code Tue, 30 Jun 2026 08:25:00 GMT I state what I want in Korean, Claude builds it, Codex attacks it, and I keep only the rulings and the dangerous buttons. For someone who cannot read code, trusting the output means measuring behavior rather than reading the source. aisecond brain https://wb3vb.com/en/2026/06/brain-in-a-coding-tool https://wb3vb.com/en/2026/06/brain-in-a-coding-tool Fri, 19 Jun 2026 22:10:00 GMT Karpathy's LLM Wiki note flips the roles: the wiki is maintained by an AI, not by people. A coding tool that works inside a folder you point it at turned out to be the right vessel. What I changed rather than copied is what became Neurain. aisecond brain https://wb3vb.com/en/2026/06/ai-assistant-amnesia https://wb3vb.com/en/2026/06/ai-assistant-amnesia Mon, 15 Jun 2026 09:40:00 GMT Running an AI as a Telegram assistant widened what I could hand off, but conversations were forgotten, sessions never talked to each other, and switching models reset everything. The bottleneck was not model intelligence. It was the absence of a structure that holds context. aisecond brain https://wb3vb.com/en/2025/09/how-to-study-economy https://wb3vb.com/en/2025/09/how-to-study-economy Fri, 26 Sep 2025 23:13:01 GMT I laid out my own study order: capitalism, money supply, bonds, rates, real estate, stocks, commodities, coins, geography. Each step explains why it sits there. investment https://wb3vb.com/en/2025/09/sijang-jeonmang https://wb3vb.com/en/2025/09/sijang-jeonmang Sun, 21 Sep 2025 12:02:20 GMT Housing prices are lease-deposit growth times the multiple interest rates set. A permitting cliff, more demolitions, and rate normalization now turn both axes one way. real estate https://wb3vb.com/en/2025/09/thoughts-on-9-7-regulation https://wb3vb.com/en/2025/09/thoughts-on-9-7-regulation Tue, 09 Sep 2025 11:03:31 GMT The September 7 measures are less a stabilization plan than a handover of supply to the public sector. Behind the unit count, the lease deposit dies and taxation waits. real estate https://wb3vb.com/en/2025/09/krw-stablecoin-structure https://wb3vb.com/en/2025/09/krw-stablecoin-structure Fri, 05 Sep 2025 01:51:51 GMT KRW stablecoins likely split distribution, infrastructure and issuance three ways. Trades clear off-chain, settle on-chain, so the Layer-1 opening is stage-two expansion. stablecoin https://wb3vb.com/en/2025/08/weonhwa-seuteibeulkoin-donghyang-krw-stablecoin-status https://wb3vb.com/en/2025/08/weonhwa-seuteibeulkoin-donghyang-krw-stablecoin-status Wed, 27 Aug 2025 07:30:43 GMT Only the Bank of Korea may issue currency, so private KRW stablecoins are effectively blocked. Four 2025 bills are compared on licensing, reserves, and interest. stablecoin https://wb3vb.com/en/2025/08/seuteuraipeuwa-seokeulyi-l1-beulrogcein-culsi-geodae-cein-jeonjaengyi-seomag https://wb3vb.com/en/2025/08/seuteuraipeuwa-seokeulyi-l1-beulrogcein-culsi-geodae-cein-jeonjaengyi-seomag Mon, 18 Aug 2025 06:44:47 GMT Stripe and Circle building their own L1s is a bet on owning the financial ledger itself. It could bring millions on-chain, but also revive Web2 walled gardens in Web3. stablecoin https://wb3vb.com/en/2025/08/hwagryuljeog-sago-probabilistic-thinking https://wb3vb.com/en/2025/08/hwagryuljeog-sago-probabilistic-thinking Mon, 18 Aug 2025 06:04:48 GMT Logical investing can still lose money, but the higher-probability side wins out over time. Input to frame to output, applied to gold versus gold-miner ETFs by scenario. investment https://wb3vb.com/en/2025/08/ai-sidae https://wb3vb.com/en/2025/08/ai-sidae Wed, 13 Aug 2025 13:19:58 GMT AI is getting better than us at writing, medicine, law, and the rest. What is left is becoming someone others want to be around, and saying clearly what you want. ai https://wb3vb.com/en/2025/08/sseunsori-harsh-criticism https://wb3vb.com/en/2025/08/sseunsori-harsh-criticism Tue, 12 Aug 2025 11:58:25 GMT The index rises, institutions chase alpha, individuals ride beta. Arrogance and bigger bets drag them to zero, so stop fighting the market and trust time. thoughts https://wb3vb.com/en/2025/08/nan-i-geimeul-haebwasseoyo-ive-played-this-game-before https://wb3vb.com/en/2025/08/nan-i-geimeul-haebwasseoyo-ive-played-this-game-before Mon, 11 Aug 2025 13:47:42 GMT Saving a paycheck and investing hard alone will not reach financial freedom. This forced Squid Game takes capital, investing, borrowing, and maintaining power. investment https://wb3vb.com/en/2025/08/fred-haedogbeob https://wb3vb.com/en/2025/08/fred-haedogbeob Mon, 11 Aug 2025 13:42:13 GMT Sorts the Fed balance sheet into five FRED lines: reserves, TGA, reverse repo, securities, and loans. Reads each line rising or falling as liquidity added or drained. economy https://wb3vb.com/en/2025/08/coegeun-saenggagdeul-recent-thoughts https://wb3vb.com/en/2025/08/coegeun-saenggagdeul-recent-thoughts Mon, 11 Aug 2025 13:37:26 GMT Stablecoin revenue rides on reserve interest, so it gets chopped once rates fall. SLR easing likely feeds buybacks, and I see an Aug-Oct correction then a year-end rally. investment https://wb3vb.com/en/2025/08/keuribto-tuja-peureimweokeu-crypto-investment-thesis https://wb3vb.com/en/2025/08/keuribto-tuja-peureimweokeu-crypto-investment-thesis Mon, 11 Aug 2025 13:22:04 GMT I have no short-term alpha, so I went from bottom-up to top-down. The crypto-dollar-AI cycle, fed by stablecoin demand for Treasuries, is my alpha for 3-5 years. investment https://wb3vb.com/en/2025/08/mempul-seunaiping-mempool-sniping https://wb3vb.com/en/2025/08/mempul-seunaiping-mempool-sniping Mon, 11 Aug 2025 13:19:11 GMT An Ordinal bought on Magic Eden may never arrive, sniped with RBF while the transaction sits in the mempool. The seller PSBT is signed ANYONECANPAY, so nothing stops it. bitcoin https://wb3vb.com/en/2025/08/biteukoingwa-eosaeghaeyo-sirijeu-2-biteukoin-gaebal-topabogi https://wb3vb.com/en/2025/08/biteukoingwa-eosaeghaeyo-sirijeu-2-biteukoin-gaebal-topabogi Mon, 11 Aug 2025 13:17:44 GMT Bitcoin has no leader, so code changes move through the mailing list and the BIP process. This traces that path, the groups funding it, and a Korean developer's account. bitcoin https://wb3vb.com/en/2025/08/eoseowa-s-s-s-shared-sequencer-suave-neun-ceoeumiji https://wb3vb.com/en/2025/08/eoseowa-s-s-s-shared-sequencer-suave-neun-ceoeumiji Mon, 11 Aug 2025 13:16:26 GMT Single-sequencer rollups face SPOF and MEV monopoly, so shared sequencers and SUAVE step in. As proposer and builder, the two make cross-chain trades efficient and safe. ethereum https://wb3vb.com/en/2025/08/mev-series-3-censorship-resistance-solutions-builder-centralization https://wb3vb.com/en/2025/08/mev-series-3-censorship-resistance-solutions-builder-centralization Mon, 11 Aug 2025 13:14:20 GMT PBS and crList answer censorship at Ethereum's protocol level. But they also hand Builders more power, and Flashbots proposes SUAVE against that centralization. ethereum https://wb3vb.com/en/2025/08/kbw2022-bitalrig-gangyeon-post-merge-next-step-for-ethereum-full-ver-beonyeogbon https://wb3vb.com/en/2025/08/kbw2022-bitalrig-gangyeon-post-merge-next-step-for-ethereum-full-ver-beonyeogbon Mon, 11 Aug 2025 13:13:23 GMT Vitalik Buterin covers Proof of Stake, rollup scaling, and the payments and non-financial apps cheap fees unlock.

I see burning as raising security. ethereum https://wb3vb.com/en/2025/08/3-ideorium-syading-sharding-yi-seonggong-yeonghyanggwa-ihu-l1-l2-ceinyi-heureume-daehan-saenggag https://wb3vb.com/en/2025/08/3-ideorium-syading-sharding-yi-seonggong-yeonghyanggwa-ihu-l1-l2-ceinyi-heureume-daehan-saenggag Mon, 11 Aug 2025 13:10:44 GMT Even after sharding succeeds, L2s and rival L1s should coexist with Ethereum as a Universal Settlement Layer. L1 chains need PMF and Ethereum compatibility. ethereum https://wb3vb.com/en/2025/08/2-naneun-wae-ideoriumeul-maesuhaneunga-seuteiking-doen-ideoriumeun-eonje-pulrilgga https://wb3vb.com/en/2025/08/2-naneun-wae-ideoriumeul-maesuhaneunga-seuteiking-doen-ideoriumeun-eonje-pulrilgga Mon, 11 Aug 2025 13:08:17 GMT Staked ETH is not withdrawable right after the Merge; unstaking opens with the Shanghai upgrade. Epoch caps and the churn limit release it slowly, easing sell pressure. ethereum https://wb3vb.com/en/2025/08/1-naneun-wae-ideoriumeul-maesuhaneunga-the-possibility-of-deflation https://wb3vb.com/en/2025/08/1-naneun-wae-ideoriumeul-maesuhaneunga-the-possibility-of-deflation Mon, 11 Aug 2025 13:02:12 GMT After the Merge, issuance to validators shrinks while the EIP-1559 burn is projected to exceed it. The case for buying is not a price call but which L1 has real revenue. ethereum
