Michael Folkson summarizes fuzz testing, a technique of feeding a program like Bitcoin Core varying malformed inputs for purposes of finding bugs. This week’s newsletter summarizes posts to the Bitcoin-Dev mailing list about payjoin adoption and making hardware wallets compatible with more advanced Bitcoin features. As of this writing, all pools listed on the site-who represent more than half of the current network hash rate-have indicated that they will support activation. Compared to previous designs for payment pools (such as joinpool), the CoinPool design focuses on allowing participants to make offchain commitments to transactions between the members of the pool. ● CoinPool generalized privacy for identifiable onchain protocols: Antoine Riard and Gleb Naumenko posted to the Bitcoin-Dev mailing list about payment pools, a technique for improving privacy against third-party block chain surveillance by allowing several users to trustlessly share control over a single UTXO. ● Making hardware wallets compatible with more advanced Bitcoin features: Kevin Loaec started a discussion on the Bitcoin-Dev mailing list about how hardware wallets could be changed to allow them to handle scripts more complicated than single-sig or multisig

However, the higher the expiry is, the more time a payment could become temporarily stuck in an open channel (either by accident or deliberately). The network-wide HTLC limit of 0.043 BTC prevents payments greater than that amount over a single channel. This prevents an outside observer examining block chain data from assuming all inputs in that transaction belong to the same user (e.g.1). If the taker preserves their own individual privacy, the makers also indirectly gain increased privacy against third party block chain surveillance. 120), Bastien Teinturier posted a proposal to have both the party offering an HTLC and the party receiving it each pay fees to the other-although the receiving party receives a refund on their fees if the payment is settled within a specified amount of time. His rulings have made smart references to "The Big Lebowski," "Dr. Strangelove," and "SNL" parodies of the McLaughlin Group. Bitcoin influencers and enthusiasts from around the world have also flocked to the crypto paradise, and some have even started to copy Peterson's experiment elsewhere. With P2P, you can easily buy and trade crypto from the peer-to-peer exchange, while OTC allows for large trades. Early efforts to that end included adding a BIP111 services flag to indicate whether or not a node supports bloom filters so that clients can find supporting nodes, and a peerbloomfilters configuration option that allows node users to disable bloom filters in case they’re worried about the DoS attac

Here's a case where an overseas exchange is offering an 'escrow service' that virtually matches a local buyer and seller in an offshore marketplace though the payment is settled here in INR. Consider Binance: this mainland China backed exchange pretending to be a Hong Kong exchange appeared out of nowhere with fake volume and demonstrated the gullibility of the entire industry by being treated as if it were a respected member. Binance, the original platform, despite its many outages in recent months, stands out from its U.S. The move comes as the U.S. At the time of the U.S. Discussion was still ongoing at the time of this writing. MULTISCHNORR I guess which has multiple public keys but still only a single signature. ZmnSCPxj replies that anything under 64 bytes could still be vulnerable, but that the 65-bytes-or-greater rule seems fine. Fournier questioned the utility of combining visit the next page private key plus the randomness using an xor operation rather than a more standard method of hashing the private key with the randomness. The previous standard protocol uses four transactions. One suggestion by Craig Raw was to extend the protocol to allow it to work even when the receiver doesn’t operate a serv

Because this is MuSig n-of-n key aggregation, it doesn’t require interaction. He first describes the savings available to users of threshold keys, aggregated public keys that only require a subset of the original parties in order to create a valid signature, such as an aggregated key created from three individual keys that can be signed for by any two of the participants for 2-of-3 multisig security. The proposed protocol contains a significant number of differences from Wasabi’s current protocol (such as replacing blind signatures with keyed-verification anonymous credentials), so its authors are seeking review, criticism, and suggestions about how the protocol can be used most effectively. ● Optech schnorr/taproot workshops: Optech is hosting workshops in San Francisco (September 24) and New York (September 27) on schnorr signatures and taproot.
