One Word: Bitcoin

[stantonchacon]

<br> While I primarily foresee points/enhancements that will have an effect on Revault, I could be really pleased to see individuals joining this thread with another ideas and remarks that might benefit some elements of Bitcoin that I missed. While this can be exploited for charge attacks, it’s a much bigger menace to pre-signed transactions protocols. A decisive, high-quantity break above this channel would sign that further beneficial properties are likely forward, whereas a break beneath this channel would improve the probability of further downside action. Because it tracks price motion that has already occurred, it’s a lagging indicator. This is the classic “chicken and egg” drawback with new know-how: new expertise will not be worth much till it’s value lots. As such, it is merely an excessive example- not a plan for a way bitcoin will grow to handle wider wants (as a decentralized system it is the bitcoin utilizing public who will resolve how bitcoin grows)- it’s simply an argument that reveals that bitcoin’s core design can scale a lot better than an intelligent person would possibly guess at first. This can be rather more environment friendly than Bitcoin’s current multisig, which requires placing k signatures and n pubkeys into transactions for okay-of-n safety, whereas multiparty ECDSA would at all times require just one signature and one pubkey for any ok or n. Bitcoin’s value plunges once more, persevering with a rapid drop in December 2017, and leading to but more hypothesis of a everlasting bubble burst. Bitcoin’s designation as a commodity opens a wealthy alternative for ICE: It now operates the 2 of the largest commodities futures exchanges on the planet-ICE Futures U.S., and ICE Futures Europe. By distinction, chia lisp has fewer opcodes than Simplicity’s jets, has possible approaches to low-impression gentle forks to extend functionality, can be utilized with only two ranges of abstraction (lisp with macros and the opcodes-only vm level) that appear not too unhealthy to understand, and (for my part) doesn’t seem too laborious to implement/maintain reasonably. This is weak security and bad user experience. The postulate we begin from is that Hardware Wallets (HW) are helpful to mitigate the compromission of the day-to-day gadget of a consumer. The proper usage could be for a user to verify this handle on a 3rd system (cell phone, for example). The Bitcoin you purchase might be sent to this handle. Problem: A typical HW at the moment would show the “destination” of a transaction in the form of a bitcoin handle.
Problem: Poisoned inputs are a major risk for HW as they do not know the UTXO set. Problem: http://www.youtube.com at the moment HW can’t “identify” addresses or keys. Proposed improvement: The HW may know pubkeys or xpubs it doesn’t hold the private keys for, and show a label (or understand it for logic causes, comparable to “expected pubkeys” as the earlier instance). Going further, the xpubs could possibly be aliased the first time they are entered/verified (as a part of, say, an preliminary setup ceremony) as an illustration with the beforehand mentioned Miniscript policy: or(pk(Alice), and(pk(Bob), after(42))). The technical crew will always hold you with assist at any time even when the product is at you and ready to be altered or changed if something it’s good to upgrade later. Then there is PSBT support and the utmost transaction measurement restrict for these: we’d like extra transparency from HW manufacturers on their li mitations. Or maybe you can arbitrarily restrict the strings to a max of 520 bytes at a consensus stage, and the corresponding Simplicity sorts to 4160 bits and go from there? Simplicity requires finite varieties. Proposed enchancment: for protocols that requires it, protecting monitor of inputs already signed once could be extraordinarily useful.
This e mail discusses enhancements that might benefit everyone, and some that are more appropriate for “layer 2” or pre- signed transactions protocols. Hello everybody, I would like to start out a dialogue on bettering Hardware Wallets. 4715 adds a –reset-wallet-transactions configuration parameter that will take away all onchain transactions from LND’s wallet and then begin a rescan of the block chain to repopulate the wallet. We’ll confirm account balances prior to name resulting from demand. If we were to undertake this, obviously we should not call it “chia lisp” anymore, because it wouldn’t work the same in vital methods. Miners in the Bitcoin blockchain community all try and confirm the identical transaction concurrently. Going further, most of those protocols require to comply with a selected signing order (sometimes the “clawback” first, then the regular spend path) so adding a approach to check that a “clawback” has been signed first, with the same enter, would be very helpful.

Still others avoid banks for philosophical reasons, preferring to decide out of mainstream society and all its trappings. I do not think they’ve solved the broader problem, and thus I believe it nonetheless makes more sense to stick with bitcoin’s present mannequin<br>e.
