Altogether this should reduce the amount of trust users need to place in the developers of Bitcoin Core and the software used to build Bitcoin Core. Both loop in and loop out are trustless except for the need for one party to pay a transaction fee if the other party backs out of the swap. E-commerce doesn’t have the same kind of physical, personal interaction that traditional commerce has, and for some consumers, the asocial experience of sitting behind a screen and clicking a virtual cart icon isn’t as desirable as the experience of actually getting out and pushing a cart around, even if it can be easier. As the tension builds up, the price often makes a big impulse move, eventually breaking out of the range. Although this merged PR only builds Linux binaries, it is expected that support for Windows and macOS will follow. 15277 allows the Linux versions of Bitcoin Core to be deterministically compiled using GNU Guix (pronounced “geeks”). In the first phase, money is transferred using HTLCs locked to a preimage not known to the receiver. Note also that any solution to Bitcoin’s first problem above, will necessarily exacerbate the second problem.

● LND 0.7.0-beta released: this new major version is the first to contain a watchtower implementation that allows third parties to help defend the in-channel funds of offline users. The Loop software is compatible with recent versions of LND. For more information, see PR author Carl Dong’s recent talk from the Breaking Bitcoin conference (video, transcript). Schnorr signatures based on bip-schnorr save a few bytes because of their more efficient encoding compared to DER-encoded ECDSA signatures, but their most significant savings in the gossip improvement proposal comes from the ability to aggregate the two signatures for a channel announcement into a single signature using MuSig. With the new loop in feature, LN users can conveniently refill their exhausted channels without using a custodial service. An update to the system now allows users to do the opposite: exchange bitcoins in a regular onchain UTXO for bitcoins in one of their LN channels, called a loop in. Bitcoin Classic stands for the original Bitcoin as Satoshi described it, “A Peer-to-Peer Electronic Cash System”.

784 updates BIP174 Partially Signed Bitcoin Transactions (PSBTs) to include a BIP32 extended pubkey (xpub) field in the global section. Optional message extensions using Type-Length-Value (TLV) records allow omitting unnecessary details when the protocol defaults are being used (for more info here information about TLV, see the notable code and documentation changes section below). It gives the Treasury Department the ability to force banks to keep records that make it easier to spot a laundering operation. Hayek advocates a complete free market in the production, distribution and management of money to end the monopoly of central banks. What we are witnessing now are merely FOMO driven dumps as speculators leave the market. Electrum has seen some reports though, which are public, such as “strange addresses” and “Localbitcoins does not support sending to bech32”. Mazars added it was pausing such work due to concerns about “the way these reports are understood by the public.” Mazars went on state that such reports had limitations in terms of providing assurances. Store of Value: Bitcoin is often called “digital gold” due to its limited supply and perceived ability to preserve wealth over time. The advantage of this method is that it allows the spender to prevent a payment from succeeding up until the last moment, allowing them to unilaterally cancel stuck payments or even try sending the same payment over multiple routes simultaneously to see which succeeds the fastest (before canceling the slower payments).

This week’s newsletter announces the newest release of C-Lightning, briefly describes several proposals related to LN, and provides our usual sections about bech32 sending support and notable changes to popular Bitcoin infrastructure projects. For one of the exchanges, he initially recorded it as supporting sending to bech32 addresses-but later he discovered its support wasn’t entirely complete. If that happens, it’ll be even more important for other wallets and services to support sending to bech32 addresses. Another problem was accepting all-lowercase bech32 addresses but not all-uppercase bech32 addresses. We solicited input from a number of services including BitGo, BRD, Conio, Electrum, and Gemini regarding their customer support burden from use of bech32 addresses. 1. Generate two addresses of your own, one for P2WPKH and one for P2WSH. Only one of Christodoulou’s 18.1 bitcoin was spared because he transferred it to a bitcoin savings service called BlockFi. One service said, “So Bitcoin address-related customer support tickets increased 50%, but the absolute number of tickets is so small that not sure we can give too much significance.
