Bitcoin Core refuses to relay or mine transactions smaller than 82 bytes. The standardization of these preimage fields was found to be necessary for Suggested Internet page miniscript-aware finalizers, though they can be used by any PSBT finalizer needing to satisfy hash preimage challenges (e.g. for onchain LN commitment transactions). In that sense, the protocol acts as a sort of generalized channel factory that applies not just to LN but to many protocols that create onchain transactions with unique fingerprints. So, we can predict that cryptocurrency transactions are going to be really quick down the road, which will help increase cryptocurrency investment down the road. Also offered is the Dual Investment Pools. 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. And you decide your customer is primarily big mining pools and businesses that just want a “full node” that runs on the network. They work through a network of computers. This prevents surveillance nodes from circumventing Bitcoin Core’s existing privacy-enhancing behavior of waiting a slightly different amount of time for each peer (or group of peers) before announcing new transactions to them, causing each transaction to propagate across the network using a different path.
Zcash proposes with security, privacy, and transparency in functioning and transactions. For privacy, the broadcast status of a transaction is only tracked if it was submitted by either the node’s wallet or the sendrawtransaction RPC. If the taker preserves their own individual privacy, the makers also indirectly gain increased privacy against third party block chain surveillance. The taker directly gains the privacy benefits of the coinjoin and the makers directly gain income for providing liquidity. ● Joinmarket has two types of users: those who pay to coinjoin (market takers) and those who are paid for allowing their UTXOs to be used (market makers). 2051: ensures that an attacker who chooses to lock his funds for a very long period of time (up to about 10,000 years) can’t cause your node to lock the same amount of your funds for the same length of time. This is where the amount of mined Bitcoins was halved, causing half the rewards for miners, for performing the same amount of work.
6), but it may result in slightly higher fees due to spending all inputs received to the same address when only a subset of those inputs might be needed. 1: partial spend avoidance is completely disabled to optimize for faster fee calculations, which may be useful for very large wallets with many UTXOs. This extends commitment transactions with two extra outputs-one for each counterparty-which can be used for Child Pays For Parent (CPFP) fee bumping. Anchor outputs also provide greater security because, if feerates do increase beyond what was predicted, the node can fee bump its commitment transaction. In practice, LN nodes using anchor outputs should normally pay lower fees because there’s no longer any incentive to overestimate fees. There’s debate between this and that economic school. This new major version allows accepting large channels (by default, this is off) and contains numerous improvements to its backend features that may be of interest to advanced users (see the release notes). All release notes since the October 2018 release of Bitcoin Core 0.17 have announced that the only supported versions of Windows are version 7 or later. 2938 delays reprocessing of incoming HTLCs at startup until after all plugins have been loaded.
19550 adds a new getindexinfo RPC that lists each optional index that has been enabled, how many blocks have been indexed so far, and whether those blocks constitute syncing all the way to the tip of the block chain. 688 adds support for anchor outputs to the LN specification. ● WabiSabi coordinated coinjoins with arbitrary output values: in the coinjoin protocol, a group of users collaboratively create a transaction template that spends some of their existing UTXOs (inputs) to a new set of UTXOs (outputs). Later, each user connects under another anonymous identity and submits each output along with its unblinded signature. ● Why isn’t RFC6979 used for schnorr signature nonce generation? To prevent that coordinator from learning which inputs fund which outputs, users anonymously commit to the outputs they want to create, receiving a chaumian blinded signature over the commitment. With this change, it becomes possible to fee bump commitment transactions that may have been signed days or weeks earlier, when the current feerates would’ve been hard to predict.
