Bitcoin - Overview > 자유게시판

15277 allows the Linux versions of Bitcoin Core to be deterministically compiled using GNU Guix (pronounced "geeks"). This is described in a new part of the BIP entitled "Change Detection" that describes how signing wallets can use this new field to identify which outputs belong to that wallet (in whole or as part of a set of wallets using multisig). Recently, an Optech contributor surveyed many popular wallets and Bitcoin exchanges to see what technical features they supported. Optional message extensions using Type-Length-Value (TLV) records allow omitting unnecessary details when the protocol defaults are being used (for more information about TLV, see the notable code and documentation changes section below). Also included are our regular sections about bech32 sending support and notable code changes in popular Bitcoin infrastructure projects. This week’s newsletter describes the availability of a libsecp256k1 fork implementing BIP-Schnorr compatible signatures, lists popular questions and answers for February from the Bitcoin Stack Exchange, and describes notable merges in popular Bitcoin infrastructure projects. This week’s newsletter announces the release of the newest version of Eclair and describes a potential routing improvement for youtu.be LN. This week’s newsletter summarizes a proposal for an update to the LN gossip protocol. By summer, Giga-Watt expects to have 24 pods here churning out bitcoins and other cryptocurrencies, most of which use the same computing-intensive, cryptographically secured protocol called the blockchain.

● C-Lightning 0.7.1 released: this new version contains new plugins and RPCs as well as numerous improvements to its handling of the channel gossip protocol that reduce the use of memory and bandwidth. Layer two solutions are thought of as one way to quickly and cheaply scale Bitcoin’s capabilities without having to overhaul Bitcoin’s primary protocol layer. Use as collateral: Another emerging idea in terms of investing in bitcoin is that it can be used as a way to digitally collateralize other non-digital assets, such as real estate or traditional stocks and commodities. Existing LN records haven’t been converted to use TLV, but subsequently-added optional records are expected to use this format. R.A. Farrokhnia, Columbia Business School professor and executive director of the Columbia Fintech Initiative, said, "It’s a marketplace and as long as people are willing to assign value to it, then that’s it." Bitcoin, the largest cryptocurrency in the world, accounting for more than half of all cryptocurrency, can be used to buy cars, furnishings, vacations and much more. So how much would it cost you to buy $10,000 of a given cryptocurrency at each level, assuming you were a taker using Advanced Trading?

The high return rate is an obvious advantage of using binary options on this platform. Put Option: Put options are below the strike price, and the trade can be made in cash or assets. The market has already spoken about which technology it thinks is best, between Bitcoin and others like Bitcoin Cash. No uniform convention for bitcoin capitalization exists; some sources use Bitcoin, capitalized, to refer to the technology and network and bitcoin, lowercase, for the unit of account. This auditable, distributed ledger that is the backbone of Bitcoin (other cryptocurrencies also rely on this technology) is called a blockchain. Other stories have been more mixed in terms of what they mean for cryptocurrencies. 15348 adds a productivity hints document describing tools and techniques developers have found to improve their efficiency. 2087 adds new fields to the results of the getinfo RPC for the number of the node’s peers, number of pending channels, number of active channels, and number of inactive channels. 2161 adds a small Python library and framework that can be used for writing plugins. It is difficult for society to work out a legal framework to differentiate between good and bad uses of this technology, says Arvind Narayanan, a computer scientist at Princeton University in New Jersey.

In separate answers, Gregory Maxwell and Andrew Chow each describe the differences between these two proposed uses of Schnorr-based signatures. Most notably, the proposal significantly reduces the byte size of messages through two mechanisms: schnorr signatures and optional message extensions. For example, if you have 100 peers, you send or receive 3,200 bytes of announcements, plus overhead, for what is (on average) just a 400 byte transaction. His definition describes a way to make it prohibitively expensive to fee bump even a small transaction that signals opt-in Replace-by-Fee (RBF). If that also doesn’t work, you’ll continue to randomly select peers to request the transaction from. This can be significantly faster than doing single multiplication in series, allowing multiple signatures to be verified together faster than they could be individually verified. Basic single pubkeys and signatures. Adapter signatures for scriptless scripts. For example, the Trezor and Electrum wallets each provide message signing support for P2WPKH and P2SH-wrapped P2WPKH addresses. Unfortunately, there’s no widely-implemented method for creating signed messages for legacy P2SH, P2SH-wrapped segwit, or native segwit addresses.
