Bitcoin Lightning Network developer updates node software with Taproot support

Lightning Labs, a developer of the Bitcoin (BTC) Lightning Network (LN), released a beta version of the Lightning Network Daemon (lnd) — a complete implementation of the LN node — with added support to the latest protocol upgrades including Taproot and Musig2 among other improvements.lnd is a software component that handles various aspects within the LN including managing a database, generating payment invoices and revoking payments to name a few. The latest software release, named lnd 0.15 beta (v0.15-beta), aims to empower developers to create solutions for more use cases by leveraging the Bitcoin network’s latest capabilities.Announcing lnd 0.15 beta: To Taproot and Beyond! ♾️Featuring:Taproot + Musig2 support for better privacy + efficiency, Taro soon™~95% database space reduction for new data️ New pathfinding tool to choose speed vs. cost of paymentsRead more: https://t.co/5pavMcpxBg— Lightning Labs⚡️ (@lightning) June 28, 2022In the announcement, Lightning Labs’ product growth lead Michael Levin revealed that over 50 contributors participated in launching the company’s first release in the year 2022, adding that:“This release gives complete Taproot support for the internal lnd wallet, making it one of the most advanced Taproot wallets today. Further, this release has support for an experimental Musig2 API compliant with the latest BIP draft.”The primary goal of MuSig2, a multi-signature scheme, is to allow the creation of aggregate public keys that can be used in Taproot outputs, thus, introducing the ability to authorize transactions with Schnorr signatures.Unlike previous versions, the beta release also removes the redundant data from the revocation log bucket, which showed a reduction of 95% in database size during initial testing. While the update does not reclaim space for existing states, Levin envisioned that a follow-up release may include a migration feature that could reclaim old disk space.Staying true to their commitment to make the LN more reliable, robust, and secure, Lightning Labs introduced greater control over pathfinding preferences — ultimately helping to reduce the transaction fees by identifying the lowest cost route.Related: Bitcoin network power demand falls to 10.65GW as hash rate sees 14% dropThe Bitcoin network recorded the year 2022’s lowest power demand of 10.65 gigawatts (GW) on June 25. As a result, the computing power for mining BTC blocks came down to 199.225 exahash per second (EH/s).Bitcoin network power demand from 2018-2022. Source: ccaf.ioThe sudden reduction in Bitcoin’s power demand is directly correlated to the falling hash rate. The mining hash rate corresponds to the computing power required by BTC miners to successfully mine a block — a key security metric.

MetaMask rolls out Apple Pay integration and other iOS updates

ConsenSys-owned MetaMask tweeted a thread of updates on Tuesday for iPhone and Apple Pay users. The main feature is the ability to buy cryptocurrency using a debit or credit card through the mobile application, eliminating the need to transfer Ethereum (ETH) from a centralized exchange like Coinbase into the app.  MetaMask Mobile v4.3.1 is LIVE with some exciting updates:Buy crypto on iOS with Apple Pay (@sendwyre), more transparency when interacting with sites, & support for gasless transactions where relevant.Does it get any better? Yes it does! We now have dark mode! 1/— MetaMask (@MetaMask) March 28, 2022MetaMask uses two payment gateways, Wyre and Transak, to support debit card and credit card transactions. Users can now use their Visas and Mastercards stored in Apple Pay to buy ETH and deposit a daily maximum of $400 into their wallets, thanks to the Wyre API. Gas fees are reportedly lower, and according to MetaMask’s tweets, some transactions may even be gasless if done on a private blockchain or if a project pays for the gas on the user’s behalf. When completing an ETH purchase, MetaMask discloses that it does not profit from gas fess.Via Transak, it’s been possible to buy the stablecoins USDT, USDC and DAI on the Ethereum mainnet in MetaMask for some time now. The latest update allows users to make bank transfers and use credit/debit cards to buy crypto using over 60 global currencies. U.S. users can also buy Fantom and Avalanche native tokens now, according to the comapany. Exact payment methods and fees vary depending on the location. James Beck, Director of Communications and Content at ConsenSys, told Cointelegraph that the purpose of the updates is to increase accessibility and reduce friction. “We wanted to expand the way in which users can convert crypto within the app itself and not have to leave it,” he said. He also revealed that more integrations that “maximize” options and “streamline” buying crypto are coming soon.MetaMask tweeted about another “important” security update when it comes to sending tokens. Unlike sending ETH simply to a recipient address, tokens are sent to a contract address and instructions are included to send a specified amount of tokens to the recipient address. Users can now “clearly see which contract is requesting” permission and to label and save that contract. An earlier Twitter thread warned MetaMask users “to be careful when interacting with contracts” and approving a certain address to move those tokens. They claimed that the token approving action could result in assets being stolen and that the only way to be protected is to revoke token allowances. The same applies when you swap/mint/sell/stake/farm on all the fancy stuff built by amazing devs the past few years.When tokens need to be moved by a contract to facilitate an action, you must first *approve* that address to access/move those tokens. This is important.7/ pic.twitter.com/FNZH8Xdl3C— MetaMask (@MetaMask) March 4, 2022

Additionally, MetaMask has introduced the Apple Dark Mode feature as per popular demand.  Beck claimed that “wen dark mode?” and “wen token” have been the most anticipated requests by their users. Dark mode will automatically enable in the app if a user’s iPhone Operating System has dark mode enabled system-wide. The company tweeted that dark mode for the MetaMask Extension “is coming soon.”Related: ConsenSys raises $450M in Series D funding, doubles valuation in four monthsRecently, MetaMask acquired the Ethereum wallet interface provider MyCrypto with the intent of combining technologies and eventually merging MyCrypto with the MetaMask wallet to improve the security of all their products.
