CHECKLOCKTIME fields. Locktime fields in Bitcoin can contain either a block height or a Unix epoch time value. Working with registered professionals may help to save time and hopefully increase your odds of a profitable investment. Sticking to a DCA plan can be a great way to set your investment strategy in stone and reduce the impact of emotions caused by price swings. A great way to keep up with current events. I think this was a great recap. In fact, I think that the threat that they pose as alternate currency can serve as a useful check on a central bank. 23480 updates the output script descriptor language with a rawtr() descriptor for referring to the exposed key in a taproot output in cases where either the key is used without a tweak (not recommended, see BIP341) or when the internal key and scripts aren’t known (which can be unsafe; see the PR comments or the documentation added by this PR for details). A previous proposal, BIP322, to provide fully generic message signing that could work with any script has not yet been merged into Bitcoin Core or added to any other popular wallet of which we’re aware. 627 adds support for P2TR keypath spends using the BitBox02 hardware signing device.

● Multiformat single-sig message signing: Bitcoin Core and many other wallets have long included support for signing and verifying arbitrary messages when the key used to sign them corresponds to a P2PKH address. 1652 updates support for onion messages with the ability to send reply paths, and to decode them when received. 23202 extends the psbtbumpfee RPC with the ability to create a PSBT that fee bumps a transaction even if some or all of the inputs to the transaction don’t belong to the wallet. Notably, invoices that require a mandatory but non-invoice feature would no longer be rejected, since the lack of support for a non-invoice feature does not affect an invoice’s ability to be fulfilled. Stickies-v provides an overview of Bitcoin Script operators, how taproot enabled with MAST improves upon spending conditions from a privacy and feerate perspective, and points out that Script’s lack of covenants makes the proposed conditions impossible solely in Script.

Ring signatures to protect sender privacy. ● Using Bitcoin-compatible BLS signatures for DLCs: Discreet Log Contracts (DLCs) allow a trusted third party known as an oracle to attest to a piece of data. While initial miniscript features will only include segwit v0 support, eventually support for tapscript and partial descriptors could make it possible to add commitments inside tapscript without solely using the raw() descriptor. Its release notes note that it includes breaking API changes but also numerous new features and bug fixes, including support for compact block relay data structures (BIP152) and improvements to taproot and PSBT support. Pieter Wuille provides a historical overview of mining-related features within Bitcoin Core over the years. The post makes a compelling case for the advantages of stateless oracles over existing DLC oracles which need to be aware of the contract at the time the contract is being created. Bitcoin Stack Exchange is one of the first places Optech contributors look for answers to their questions-or when we have a few spare moments of time to help answer other people’s questions.

A different exchange limited the length of address form fields so that they couldn’t fit all valid bech32 addresses. ● UTXO spendable by me or deposit to exchange after 5 years? 1. Sign in to the Luno app, select Wallets, then Deposit on your GBP wallet. They could then allocate their deposit funds according to the contract without even telling the oracle that they were planning to use it. Addressing the second issue, Poelstra’s post details how libsecp256k1-zkp attempts to minimize the risk of nonce-related failures and teases the possibility of even better solutions in the future. If you wish to ensure that your trade closes at the exact rate you have set without the risk of slippage, you can place a ‘Guaranteed Stop’. Mining can still occur whether transactions are added to the blockchain or not. " Though it also notes that dual funding is disabled by default and that tests for cross compatibility with Core Lightning will be added in the future. If the supply of available block weight increases and demand remains constant, we expect prices to go down (unless they’re already at the default minimum relay fee).
