Your signal. Your price.
Liquid Network attackers returned 3,400 of the 4,000 stolen Bitcoin but kept nearly 600 coins as a ransom. Adam Back confirmed the Liquid peg will remain fully covered one-to-one, while Blockstream refuses to negotiate with the hackers.
Chinese researchers claim they can break the elliptic curve cryptography protecting Bitcoin with 835 logical qubits, down 60 percent from prior estimates. Q and A notes that avoiding address reuse is vital because spent addresses expose public keys.
The Yeti Cold 2.0 protocol outlines a complex 3-of-7 multisig scheme using CD-ROMs, Bitcoin Core, and offline laptops. Max and Q and A criticize the setup as a hazardous user experience that increases the likelihood of self-custody loss.
Electrum Rust Server 0.12 introduced a new indexing library requiring a full reindex, while Fedimint patched a critical gateway payment vulnerability. Q and A also updated his open-source Bitcoin Seed Tool to support seed XOR splitting.
Recent NIP updates allow relays to signal that more filter results exist post-authentication. Additionally, the Nostr Wallet Connect specification clarified that the list transaction API must return actual transaction counts instead of raw database rows.
NIP-18 mandates kind 6 events for kind 1 reposts, while other kinds must use kind 16 with a "k" tag. NIP-25 defines kind 7 reactions, requiring "+" for upvotes, "-" for downvotes, and custom emojis to avoid automated vote interpretation.
An attacker exploited Liquid's consensus engine to drain 4,000 BTC from its 11-of-15 multisig federation. The hacker returned 3,400 BTC but kept 600 BTC as an involuntary bounty, demanding a 10% voluntary payment for the rest.
Blockstream communicated with the Liquid hacker via PGP-encrypted onchain messages before the attacker threatened to publish negotiations in plain text. Blockstream plans to pursue every legal avenue to recover the remaining 600 stolen Bitcoin.
Security researcher Cali publicly claimed Blockstream could have avoided the Liquid exploit by answering red team emails. Keon criticizes this as clout-chasing influencer behavior, arguing that effective security work must be conducted quietly.
Den questioned whether anyone can successfully launder stolen Bitcoin. Keon notes the cold card hacker attempted to launder funds through CoinJoin, ThorChain, and Ethereum swaps, but the efficacy of maintaining unlinkability across these protocols remains highly uncertain.
The BIP 300 drivechain fork, branded as e-cash, is scheduled to launch on October 31, coinciding with Bitcoin's 18th anniversary. The project uses SHA-256 mining to enable optional, sidechain-based features.
Summerwill clarifies that the DAO rescue hard fork was an irregular state transition rather than a blockchain rollback. It transformed the targeted smart contracts into simple refund contracts, effectively transferring coin ownership without the use of private keys.
Ethereum Classic survived the split because its rapid difficulty adjustment algorithm prevented block production from stalling. In contrast, Bitcoin hard forks with slow adjustments often grind to a halt when they lose majority hash power.
The host notes that the 21 million coin cap is absent from the original white paper. A November 2008 pre-release client yielded a total supply of 20 million coins due to its 100-coin block reward.
The host criticizes the BIP 110 Blake fork as reductionist and authoritarian. The project artificially shrinks block sizes and relies on easily manipulated Discord votes to bypass miner consensus, undermining Bitcoin's original design.
Summerwill highlights data showing Ethereum's Layer 2 ecosystem capitalization reached 30 percent of its Layer 1 value. In comparison, Bitcoin's L2 market share, including Liquid and Stacks, languished at roughly 1 percent of its Layer 1 value.
Tyler Warner reports that AI coding agents helped researchers decrease the benchmark for a key step in a quantum attack on Bitcoin and Ethereum by 86%. David Bennett criticizes the report for framing a global cryptographic threat as only a cryptocurrency issue.
The Ethereum Foundation set a hard December 2029 deadline to make transactions, validators, and storage quantum resistant. Meanwhile, NIST drafts propose deprecating classical public key algorithms after 2030 and disallowing them entirely after 2035.
Ezra Regreira reports that Blockstream refused to pay a 10% ransom to hackers who exploited the Liquid Network federation wallet. The hackers initially withdrew 4,000 Bitcoin but returned 3,400 after Blockstream patched the affected bridge nodes.
Jordan signs Ashigaru Desktop releases with his BIP-47 code. To protect user privacy, the software automatically sanitizes exported logs to strip out private addresses or transaction details.
Users without a personal Electrum server can discover alternative trusted nodes. The app connects to the Dojo Bay reference instance over Tor to locate available Electrum servers.
Whirlpool mixes on Ashigaru Desktop operate in 0.025 BTC and 0.25 BTC pools. Change that falls below these minimums goes to the bad bank, which cannot be mixed.
The Mix To feature allows users to route coins automatically to a hardware wallet, such as Passport Prime, once they reach a specified mix count. This process uses watch-only output descriptors.
Blockstream Liquid was hacked for 4,000 BTC after an attacker exploited an inflation vulnerability. The exploit resulted from a flawed code patch released on September 1, 2024, which attempted to fix an older 2018 range proof vulnerability.
Adam Back announced the Liquid network peg will remain one-for-one. Blockstream and its partners are plugging the remaining 600 BTC deficit after the hacker returned 3,400 BTC through encrypted OP_RETURN negotiations, keeping 15 percent as an unsolicited bounty.
The Liquid exploit exposed structural risks in federated sidechains, where members blindly run software updates without auditing the code. The attacker bypassed security controls by exiting through Sideswap, a federation member that lacked KYC or transaction velocity controls.
Bob Burnett estimates that public mining companies have dropped their share of the network hash rate from nearly 40 percent down to around 28 percent. This shift decentralizes the physical distribution of hashing power across the network.
Nacho Pauls reports that Ocean's hash rate dropped from 40 exahashes to 23 exahashes following the controversial BIP-110 hard fork. Despite the decline, the pool remained functional and profitable for miners who chose to stay.
Bob Burnett stopped signaling for the BIP-110 proposal on June 1st after recognizing a complete lack of broader ecosystem consensus. He argues that pursuing technical updates is useless without the explicit support of pools, exchanges, and node operators.
Bob Burnett argues that the Bitcoin network needs three to five independent node clients with significant market share to safely negotiate future protocol upgrades. He models this after the historical standardization of PC components like USB and PCI.
