  • Crypto fund KR1 invests further in cross-chain liquidity protocol HydraDX

    Crypto fund KR1 invests further in cross-chain liquidity protocol HydraDX

    [ad_1]

    KR1, a blockchain and crypto-asset investment company, has now announced it has participated in the HydraDX (HDX) crowdloan and Polkadot (DOT) parachain auction. KR1 contributed a total of 350,000.00 DOT to the HydraDX crowdloan campaign, which successfully secured a parachain slot in the ongoing round of Polkadot parachain auctions.

    HydraDX.io is a cross-chain liquidity protocol designed to enable frictionless liquidity for crypto assets across various chains. In contrast to most decentralized exchanges in production today, which rely on separate pools for separate assets, HydraDX’s solution enables deposits of ‘all’ assets into one shared liquidity pool, the ‘Omnipool’, unlocking unparalleled efficiencies.

    The contributed DOT will be time-locked on the Polkadot blockchain for 96 weeks and will be returned to KR1 following the completion of the respective HydraDX parachain lease. Following the successful HydraDX parachain auction bid, KR1 is going to receive a to-be-determined amount of HydraDX tokens over a time period of 96 weeks in return for supporting the HydraDX crowdloan campaign.

    This method of token distribution involves no direct investment of capital, instead, it is an indirect investment with the opportunity costs being the inaccessibility of the locked DOT funds as well as foregoing any staking yields on the contributed DOT for the time period.

    In addition, KR1 will receive a total of 45,000,000 HDX tokens (and a yet-to-be-determined amount of Basilisk (BSX) tokens) in line with KR1’s previous backing of HydraDX’s seed funding round that was announced on December 22nd, 2020, and a much smaller, yet-to-be-determined amount of HDX tokens in line with the company’s contribution to Basilisk’s Kusama crowdloan campaign and parachain auction that was announced on September 22nd, 2021.

    HDX is the native token of HydraDX. It will be used for governance, staking, and more.

    “HydraDX winning a Polkadot parachain slot is the next big step for the project and a huge endorsement by the community of the protocol’s objective to bring all liquidity together in an ‘ocean of liquidity.’ We see HydraDX as the endgame of liquidity in a cross-chain world and we have a high conviction rate in the team’s ability to achieve this goal.”
    – Keld van Schreven, Managing Director & Co-Founder of KR1

    Bitcoin Recovery Halts, Technicals Suggest Fresh Decline To $36K

    [ad_1]

    Bitcoin is struggling to recover above the $38,400 resistance zone against the US Dollar. BTC could resume decline if it stays below the $38,500 level.

    • Bitcoin is currently facing resistance near the $38,400 and $38,500 levels.
    • The price is trading below $38,500 and the 100 hourly simple moving average.
    • There is a crucial bearish trend line forming with resistance near $38,450 on the hourly chart of the BTC/USD pair (data feed from Kraken).
    • The pair could start a fresh decline if there is no clear move above $38,500.

    Bitcoin Price Faces Hurdle

    Bitcoin price found support near the $36,350 after a sharp decline. BTC formed a base and started a recovery wave above the $37,000 level. The price was able to surpass the $37,500 resistance level.

    The bulls pushed the price above the 50% Fib retracement level of the key decline from the $39,492 swing high to $36,366 low. There was also a push above the $38,000 level. However, the price is now facing a strong resistance near the $38,250 level.

    To gain bullish momentum, the price must settle above the $38,800 level. In the stated case, there are chances of a move above the $39,500 resistance.

    Fresh Decline in BTC?

    If bitcoin fails to start a recovery wave above the $38,400 resistance zone, it could start a fresh decline. An immediate support on the downside is near the $37,250 zone.

    The next major support is seen near the $37,000 level. If there is a downside break below the $37,000 support zone, the price might gain bearish momentum for a move to $36,000. Any more losses could lead the price to $35,000.

    Technical indicators:

    Hourly MACD – The MACD is now losing pace in the bullish zone.

    Hourly RSI (Relative Strength Index) – The RSI for BTC/USD is declining towards the 50 level.

  • WEFUZZ, a fully decentralized, crowdsourced security audit and bug bounty solution | by Coinbase | Feb, 2022

    WEFUZZ, a fully decentralized, crowdsourced security audit and bug bounty solution | by Coinbase | Feb, 2022

    [ad_1]

    Coinbase

    This report updates on what WEFUZZ, Coinbase Crypto Community Fund grant recipient, has been working on over the first part of their year-long Crypto development grant. This specifically covers their work on a decentralized, crowdsourced security audit and bug bounty solution.

    By WEFUZZ, Coinbase Crypto Community Fund grant recipient

    WEFUZZ implements a fully decentralized, crowdsourced security audit and bug bounty solution: a set of smart contracts that allow developers and companies to get their smart contracts, blockchains, websites, etc., audited by the auditors and hackers community. With this work, WEFUZZ aims to become the *Hacker DAO*.

    Crowdsourcing is a sourcing model in which individuals or organizations obtain goods or services — including ideas, voting, micro-tasks etc., from a large, relatively open, and rapidly evolving group of participants. Companies like Uber, Gitcoin and GoJek already use this model. Crowdsourcing model offers improved costs, speed, quality, flexibility, scalability, and diversity.

    The traditional crowdsourcing system consists mainly of three roles: requesters, workers (auditors in our case), and a centralized system. Requesters submit tasks to be completed through the crowdsourcing system. A set of auditors complete this task and submit solutions to the crowdsourcing system. Requesters will then select a proper solution (usually the first or the best one that solves the task) and reward the corresponding worker

    This makes centralized systems vulnerable. User’s sensitive information (e.g. name, email address etc.,) and vulnerability reports are saved in the database of these centralized systems, which has the inherent risk of privacy disclosure and data loss. Centralized choke points are not only attack vectors for leaks and hacks, but also for outages.

    Crowdsourcing companies are keen on maximizing their benefits and require requesters paying for services, which in turn increase user’s costs. Most crowdsourcing systems demand a 10–25% service fee.

    All these issues add up to the already existing concerns of smart contract and multi-chains owners and developers (the audit requesters), freelance auditors’ and ethical hackers’ concerns. Some of these concerns are:

    • Ensuring their assets are safe from cyber theft, data hacks or any other risk that can result in a loss of funds and compromised data
    • Being able to get audits done in a cost-effective way — be it private or public security audits
    • Making sure the smart contracts are audited by multiple auditors
    • Hackers do not want to share sensitive personal data
    • Hackers and auditors and developers need complete transparency

    WEFUZZ is a fully decentralized, crowdsourced audit and bug bounty platform aiming to be the Hacker DAO. WEFUZZ aims to provide reliability, fairness, security and low service fees by design.

    The decentralized platform has many advantages such as higher user security, service availability, and lower costs. Smart contracts running on a chosen blockchain are used to perform the whole process of crowdsourcing tasks which contains posting audit and bounty campaigns, submitting audit and bug reports, bounty assignment, etc.

    WEFUZZ solution offers numerous added benefits to users:

    • Data Security: Reports are encrypted with auditors’ and target developers’ public key, so that the bug reports only gets read by who it is intended for. Files are encrypted and stored on the decentralized network storage. No more data breaches, hacks, password leaks or any other risk affecting existing cloud based audit and bug bounty platforms.
    • Cost Effectiveness: Allowing smart contract developers, multi-chain developers, and companies to get audits performed in a cost-effective way directly by the auditors and hacker crowd on the WEFUZZ platform. This helps the developers and companies avoid huge fees and congestion issues affecting the traditional bug bounty platforms.
    • Flexible anonymity: Auditors and hackers can choose to remain anonymous while submitting reports, protecting their privacy, and still getting paid.
    • Communication Security: No centralized data storage, complete anonymity, no data transfers, no moderators and complete end-to-end encryption. All the data resides encrypted on the Solana blockchain and all the files reside on the IPFS blockchain.

    Audit Requestors: Developers, companies or any individual can request audits or start a private/public bug bounty campaign.

    Auditors: Auditors can be anyone from ethical hackers to audit firms who can perform the requested audits or participate in bug bounty campaigns.

    Judges: Judges are community members who are either elected by the community or have been raised to the Judge category through reputation.

    Currently, we are working on the conceptualization, technical architecture, and system design of WEFUZZ, besides building our MVP on Solana and Polygon blockchains, and testing the optimal chain for our project.

    Please join our Discord and follow us on our Twitter and Medium to keep track of the progress. We are going to release the code and other tools we build as part of the research and development in this Github account.

  • Explore web3 confidently with Coinbase Wallet and Ledger | by Coinbase | Feb, 2022

    Explore web3 confidently with Coinbase Wallet and Ledger | by Coinbase | Feb, 2022

    Coinbase

    By Adam Zadikoff, Senior Product Manager

    Since launching the Coinbase Wallet browser extension as a standalone self-custody option in November, we’ve seen incredible adoption. Wallet extension makes it even easier to explore web3 by bringing the world of decentralized apps (dapps) to more devices. Today, we’re adding support for Ledger hardware wallets to Coinbase Wallet extension, providing an additional layer of security and greater peace of mind for our users.

    Ledger is an industry leader in hardware wallets, with more than 4 million people putting their trust in Ledger to keep their crypto safe. To celebrate today’s launch, we have partnered with Ledger to release the Nano X Coinbase Edition, which is available for a limited time in Ledger’s online store.

    Building the most user-friendly self-custody experience in crypto means giving our users more ways to keep their crypto secure while they access web3 and the world of crypto. And today’s launch is just the beginning — we will continue to build out support for more hardware wallets across all of our users’ devices.

    Coinbase Wallet is your passport to collecting NFTs, participating in DeFi, joining a DAO, and so much more. As you start to live more of your life on the blockchain, it’s more important than ever to keep your assets safe.

    Fortunately, there are many steps you can take to keep you and your assets safe as you explore web3. It all starts with your recovery phrase, backing it up in a secure location, and making sure to never share it with anyone. And as a reminder, Coinbase will never ask you for your recovery phrase.

    Coinbase Wallet offers additional layers of security for our users. For users of Wallet browser extension, we recommend adding a password to keep your assets safe. And in the Coinbase Wallet mobile app, you can use biometrics or a PIN to secure your Wallet.

    Today, we are adding support for Ledger hardware wallets in the Coinbase Wallet browser extension, introducing an additional security option for our users. Hardware wallets are physical devices that store the private keys to your crypto wallet offline. Because every transaction on the blockchain requires both a user’s public and private keys, a hardware wallet ensures that only the user who holds the physical device can complete a transaction.

    Using a hardware wallet is a lot like using two factor authentication to secure a website login, but instead of a six digit code that is sent as an SMS or generated in an authenticator app, your hardware wallet is used to physically confirm transactions with the press of a button.

    Whether you are a first-time hardware wallet user or already have a Ledger it is easy to use Coinbase Wallet to connect to the ever-growing world of NFTs, dapps, and DeFi. All you need to do is download the Coinbase Wallet browser extension, connect your Ledger to your computer, and follow the on-screen instructions.

    While today’s launch brings support for Ledger devices to the Wallet extension, we have ambitious plans to support more types of hardware wallets not only in Coinbase Wallet extension, but with our mobile apps as well. We will soon also add support for users with multiple active wallet addresses on a single Ledger device to select which address they want to use with Coinbase Wallet.

    We want to empower everyone to use dapps and access web3, and that requires building the easiest-to-use and most accessible self-custody wallet in the ecosystem. Today’s release solves another set of important user needs, including the ability to use a hardware wallet for enhanced security.

    You can experience the latest enhancements for yourself by downloading Coinbase Wallet for free from the App Store on iOS, Google Play on Android, or the Chrome web store. Make sure to follow us on Twitter @CoinbaseWallet for the latest Wallet-related news.

    Coinbase Wallet is a self-custody wallet providing software services subject to Coinbase Wallet Terms of Service and Privacy Policy. Coinbase Wallet is distinct from Coinbase.com, and private keys for Coinbase Wallet are stored directly by the user and not by Coinbase.com. Fees may apply. You do not need a Coinbase.com account to use Coinbase Wallet.

  • Bitcoin inches past $38K as Wall Street opens to strange calm on Russia sanctions

    Bitcoin inches past $38K as Wall Street opens to strange calm on Russia sanctions

    [ad_1]

    Bitcoin (BTC) recovered to $38,000 as Wall Street opened on Feb. 22 amid a tense atmosphere over geopolitical instability.

    Bitcoin tiptoes around macro cues

    Data from Cointelegraph Markets Pro and TradingView showed an eerily calm start to the first Wall Street session of the week for both stocks and crypto.

    Fears of a dramatic bout of volatility accompanying the open thanks to Feb. 21’s announcement by Russian President Vladimir Putin that he would recognize two breakaway republics in eastern Ukraine had been high.

    Sanctions, still being announced at the time of writing, were likewise assumed to be about to fuel the fire but on the day, there was little movement.

    The S&P 500 was all but flat thirty minutes after trading began, leaving Russian markets as the main losers and gold as the standout winner.

    “I think that we’re going to open in the red and then, immediately bounce up on the risk-on assets and have a slight correction on gold,” Cointelegraph contributor Michaël van de Poppe previously forecast.

    Fellow trader and analyst Scott Melker meanwhile focused attention on the potential for the Russia-Ukraine debacle to influence policy at the United States Federal Reserve.

    According to banking giant JPMorgan, the effect of a potential conflict could be to make the Fed abandon the veracity of its planned interest rate hikes this year.

    According to a note published Feb. 22 quoted by various media outlets, analysts at JPMorgan believe that the trigger for a Fed rethink would come in the form of commodity price increases.

    “Russia-Ukraine tension is a low earnings risk for U.S. corporates, but an energy price shock amid an aggressive central bank pivot focused on inflation could further dampen investor sentiment and growth outlook,” they wrote.

    The sanctions meanwhile held off on all-out economic retaliation, with Russia’s two largest state-owned banks, Sberbank and VTB, left untouched.

    Traders take Bitcoin’s recovery one step at a time

    Looking ahead on Bitcoin, popular trader Anbessa meanwhile eschewed calm as BTC/USD conformed to expectations without a significant trend violation.

    A potential support/resistance flip near $37,700 was on the cards, he said, this hopefully becoming an important feature for the higher timeframe chart going forward.

    As Cointelegraph reported, however, Bitcoin and altcoins remain off the radar for the majority of mainstream consumers, with mostly large-volume institutional players and whales maintaining meaningful participation.

    “If we are bleeding new users but still have heavy dilution and retail outflows. There is no recovery. Maybe for BTC. But not alts far out on the risk curve,” fellow trader Pentoshi added in his own discussion of the macro environment.
