- Private Keys (privatekeys.pw)
PrivateKeys.pw describes itself as a comprehensive private key explorer, with a directory of all possible secp256k1 ECDSA private keys in decimal, hexadecimal and WIF formats. According to the site, it does not store all keys but generates them on the fly from page numbers, and it covers ten cryptocurrencies, including Bitcoin, Ethereum, Litecoin and Dogecoin. It also offers search across several formats, automatic balance checks that color wallets with a balance green, previously used but empty wallets yellow and unused wallets gray, a collection of used brainwallets, and a mnemonic converter.

- Did HTX Really Play a Role in Russian Money Laundering? (wublock.substack.com)
The article argues that the UK's May 26, 2026 designation of HUOBI GLOBAL SA, HTX's Seychelles-based entity, is an allegation rather than a proven finding. OFSI stated there were "reasonable grounds to suspect" HTX provided financial services to A7 LLC and Garantex Europe OU, and it froze assets on that basis. The author says this was the first time a G7 country placed the entity behind a top-10 centralized exchange on an asset freeze list. The article also describes a Russian pipeline running from ruble conversion through A7A5 and USDT to an exchange endpoint, and notes that the US has not sanctioned HTX.

- why we're buzzing (x.com)
Block has released Buzz, an open source workspace that puts people, agents, conversations, and code on the same level behind one cryptographic identity system, with the aim of reducing its dependence on Slack and GitHub. The article says the main problem Buzz addresses is context, since work spread across chat, code hosting, CI, and agent tools loses information at each seam. Buzz stores every message, patch, review, workflow step, and approval as a signed event on a relay that users host themselves, and agents can search history, send patches, review code, and run workflows as equal members. The project is licensed under Apache 2.0, built on Nostr, and supports harnesses for goose, codex, and claude code. Channels, threads, DMs, canvases, search, the audit log, and the desktop app work today, while full git hosting, mobile, and push are still in progress.
- RULES FOR RECORDED CONVERSATIONS (open.substack.com)
The essay argues that recorded conversations should say something new and build lasting catalogue value, which it defines as asking what an episode will be worth in three years. It says content decays at the speed of its subject, so frontier AI content goes stale faster than a show like Founders, which keeps working through lessons from dead founders. It adds that venture media can see catalogue value turn negative when a featured company fails, and it recommends designing room for disagreement, preparing carefully, and cutting conversations down to remove the "pose" effect.

- When random.bytes() runs but doesn't work (insider.btcpp.dev)
ddustin, a Core-Lightning developer, analyzes the Coldcard firmware commit history to explain how weak entropy in the device's wallet generation arose. The key commit, titled "runs" and changing 1534 lines, set MICROPY_HW_ENABLE_RNG to 0, which disabled the STM32 hardware random number generator and switched to the weaker Yasmarang RNG. According to the analysis, the change was made to silence a "duplicate symbol" compiler error caused by redefining pyb_rng_get_obj, and the overridden functions are not called by make_new_wallet(), which uses random.bytes(32) and therefore falls through to the weak generator. The post concludes that developers must fully understand and verify code they ship, especially in security-critical sections.
- @BottoDAO: Solana wind-down complete, 10% of POL now locked on Ethereum (x.com)
BottoDAO has completed the wind-down of its Solana liquidity pool, following BIP-99, and bridged the remaining liquidity back to Ethereum mainnet. The $BOTTO pool on Solana had been set up under BIP-69 and is now fully removed, which the update says closes out the Solana initiative and consolidates liquidity into one place to reduce fragmentation and operational overhead. A new v3 liquidity position has been created on Ethereum, and 10% of protocol-owned liquidity has been permanently locked via UNCX.
- Memories of a Long-Time BitMEX User: Did the March 12 Outage Save Crypto? (wublock.substack.com)
Hedge fund manager Kuan argues that BitMEX's perpetual contracts were a major innovation and that offshore exchanges' golden era has passed as the industry moves toward compliance. In a WuBlockchain podcast interview, Kuan says BitMEX's funding rates, mark prices, insurance fund and auto-deleveraging solved the liquidity fragmentation of fixed-expiry futures, and that its order book depth frequently reached millions of dollars during the 2018 bear market. Discussing the March 12, 2020 crash, Kuan says the outage interrupted a liquidation cascade and Bitcoin stabilized around $3,800, though whether it was intentional cannot be proven from outside.
- Bitcoin cold-wallet attack spreads to 4,500 addresses as losses near $89 million (coindesk.com)
Galaxy Research flagged a third wave of attacks that drained about 208 bitcoin from 1,912 addresses between Friday midday and Saturday morning UTC, bringing total losses across three waves to 1,367 bitcoin, nearly $89 million, from 4,585 addresses. The attacks exploit a vulnerability in a March 2021 Coldcard firmware release that generated seed keys with predictable software randomness instead of the chip's hardware randomness, allowing attackers to reproduce keys offline. The first wave, on July 30, took 1,083 bitcoin from 1,196 addresses in 41 minutes, averaging close to one coin per victim. Galaxy Research believes each wave comes from a single operator but cannot determine whether the same attacker is behind all three.
