The government could cryptographically prove that the Bitcoin backing digital dollars actually exists and is securely held, instead of relying on Americans' faith that hunks of gold exist in a basement somewhere. The primary advantage of gold is that you can't just print more of it. This email discusses improvements that would benefit everyone, and some that are more suitable for "layer 2" or pre- signed transactions protocols. While this can be exploited for fee attacks, it is a bigger threat to pre-signed transactions protocols. American dollars are centrally financially controled, but we can transact without that being public information. A survey of how Lightning is being used now and discussion of opportunities for Bitcoin businesses adopting Lightning. Each Bitcoin transaction contains metadata such as: the input addresses (where the money is coming from), the output addresses (where the money is going), the amount of Bitcoin actually being sent, and cryptographic signatures proving the authenticity of the transaction. Going further, the xpubs could be aliased the first time they are entered/verified (as part of, say, an initial setup ceremony) for instance with the previously mentioned Miniscript policy: or(pk(Alice), and(pk(Bob), after(42))). Relative performance is measured for each stock from the time you placed the trade (option start).

This can provide a much better controlled network environment than proof-of-work testnets where adversarial miners can use various tricks to make the network practically unusable for long periods of time. The region’s five huge hydroelectric dams, all owned by public utility districts, youtu.be generate nearly six times as much power as the region’s residents and businesses can use. However, the worldwide commercial use of bitcoin remains minuscule, indicating that few people use it widely as a medium of exchange and those that do can be encumbered by security precautions and long delays needed to verify transactions. The PSBT can then be copied to an external wallet (such as a hardware device or cold wallet) for signing. Going further, most of these protocols require to follow a specific signing order (typically the "clawback" first, then the regular spend path) so adding a way to check that a "clawback" has been signed first, with the same input, would be very helpful. If you assume it may be compromised, then the HW needs to be able to defend against those.

A quick note about Bitcoin versus bitcoin: You may notice while reading this page, or on other pages on this site that both Bitcoin with a capital B and bitcoin with a lowercase b are used. While I mainly foresee issues/improvements that may affect Revault, I would be really happy to see people joining this thread with any other ideas and remarks that would benefit some parts of Bitcoin that I overlooked. For more information on gains and losses, see Publication 544, Sales and Other Dispositions of Assets. What makes fiat more than just pieces of paper is the belief that it will have value in the future. The fact is, it doesn't have to be backed by anything except this belief. I strongly disagree with this notion, and point to the fact that fiat currency has not made gold obsolete. Troves of Bitcoin, unlike gold, can't be randomly found under the ground, debasing our currency in a way that nobody controls. Let's compare gold, the metal, with unbacked paper dollars.

Mark Erhardt: I believe you are getting that right. Bitcoin miners set up their hardware to tackle resource-intensive mathematical problems, and whoever gets the right solution first gets to add the next block to the blockchain. Problem: Poisoned inputs are a major risk for HW as they don't know the UTXO set. ● Help test LND 0.9.0-beta-rc1: this pre-release of the next major version of LND brings several new features and bug fixes. This is a major issue for anyone using Bitcoin "advanced" features. Myers’s sample implementation works by using the Bitcoin Core functional test framework to simulate payments in an eltoo payment channel. Litecoin uses much less energy than Bitcoin as well, but it’s easier for a well-capitalized group to attack. They don’t just consume energy when there is an excess of renewables, but still require power during production shortages. Bitcoin mining-the complex process in which computers solve a complicated math puzzle to win a stack of virtual currency-uses an inordinate amount of electricity, and thanks to five hydroelectric dams that straddle this stretch of the river, about three hours east of Seattle, miners could buy that power more cheaply here than anywhere else in the nation. Not only does one need to know the power requirement of the Bitcoin network, but one also need to know where this power is coming from.
