Can a fully-functional oracle network ecosystem that anonymously collects and validates geospatial (location-specific) data exist? One blockchain firm seems to have gotten the gist of the idea. Founded in 2012, XY Labs and its namesake protocol XYO, which is built on the Ethereum blockchain, seek to reward participants for the genesis, interpretation, analysis, and storage of data to be called upon for specific problems. There are currently over 4 million nodes worldwide on the XYO network. In a recent ask-me-anything (AMA) session with Cointelegraph Markets Pro, Arie Trouw, founder of XY Labs, explained that fundamental to the XYO system is a special type of payload called BoundWitnesses. It contains a list of user-input data points that are signed by one or more nodes in the XYO network. They can be modified to include time, date, and location, and be signed by nodes as to reflect the certainty of the embedded data.”The job of an oracle is to provide an answer with as much certainty as possible. We use blockchain to memorialize these answers and provide transparency into the process of creating the solutions by linking to supporting data using immutable hashes.”To ensure security, BoundWitnesses only share the hashes of payloads while keeping the payloads themself private. Each node has its own blockchain, and with BoundWitnesses, those blockchains are linked together and, as a whole, provide one reflection of the imperfect data of reality. Since inception, over 77.4 million BoundWitnesses and 244.7 million payloads have been submitted to the XYO Main Net.Together with the firm’s COIN mobile application that rewards users for data collection and production and the XYO token as a payment channel, a fully-functional marketplace is born where users can exchange data for incentives. There are approximately 12 billion XYO tokens with no fixed supply. Factors such as token inflation and burn mechanisms will affect its supply-side tokenomics.Join Cointelegraph’s markets intelligence platform Markets Pro for an exclusive AMA with leading figures in the blockchain industry every week.

MetaMask warns of security vulnerability from older versions of popular crypto wallet

MetaMask warns of security vulnerability from older versions of popular crypto wallet

Uverejnil používateľ | jún 15, 2022 |

On Wednesday, MetaMask said that it uncovered a critical security vulnerability in older versions of its crypto wallet with the help of security researchers at Halborn. The security firm was awarded a bounty of $50,000 for the discovery. For users of the MetaMask extension before version 10.11.3, three necessary conditions would have led to the potential vulnerability. They are: (1) an unencrypted hard drive, (2) having imported a secret recovery phrase into a MetaMask extension on a device that was compromised, stolen, or has unauthorized access, and (3) having used the “Show Secret Recovery Phrase” checkbox to view one’s secret recovery phrase on-screen during the import process.”We’ve only found that the Secret Recovery Phrase could be extracted under very specific circumstances, and we’ve been able to introduce new protections over the period that Halborn has waited to disclose.”Apparently, the exploit affects all browser versions of MetaMask wallet versions prior to the 10.11.3 update, and all operating systems if all three circumstances were met, but not mobile versions. MetaMask is warning affected users to migrate their funds from their compromised wallets. However, keep in mind that all three conditions need to have been met for the vulnerability to be active on older versions of MetaMask.

Kraken reiterates hiring targets as CEO denounces 'woke activists' in corporate culture

Kraken reiterates hiring targets as CEO denounces 'woke activists' in corporate culture

Uverejnil používateľ | jún 15, 2022 |

On Wednesday, cryptocurrency exchange Kraken announced that it would continue to hire over 500 roles in various departments amidst a market downturn. The company’s hiring efforts are in stark contrast to a week of severe layoff announcements from major blockchain firms such as Coinbase, BlockFi, etc. In support of the decision to expand its staff, Kraken said: “We have not adjusted our hiring plan, and we do not intend to make any layoffs. We have over 500 roles to fill during the remainder of the year and believe bear markets are fantastic at weeding out the applicants chasing hype from the true believers in our mission.”However, Jesse Powell, Kraken’s CEO, also expressed critical remarks over a small subset of employees at Kraken, estimated to be 20 out of 3,200 people. As told by Powell: “I think we’ve developed some really thoughtful policies that might not appease woke activists but work for the other 99% of the world.”Powell explained that the said employees possessed great talent, but were not a fit for the company as they were accused of focusing on “minor sights” and “first world problems” instead of the company’s stated mission of bringing financial inclusion to billions of people around the world. “Most people don’t care and just want to work,” said Powell when addressing the various social topics raised by the said subset of employees.As the year progressed, the cryptocurrency exchange became known for its frank and honest approach to everyday operations. In April, Powell made the decision to close down Kraken’s San Francisco headquarters, citing rampant crime in the area and specifically named the city’s District Attorney Chesa Boudin as being responsible.11/11 We’re going to keep building and hopefully do a better job of filtering up front. I think we’ve developed some really thoughtful policies that might not appease woke activists but work for the other 99% of the world.

ICI Bucharest to use Elrond blockchain to develop decentralized domains and an institutional NFT marketplace

ICI Bucharest to use Elrond blockchain to develop decentralized domains and an institutional NFT marketplace

Uverejnil používateľ | jún 14, 2022 |

On Tuesday, Romania’s National Institute for Research and Development In Informatics, also known as ICI Bucharest (ICI), announced that it would be building an institutional nonfungible tokens, or NFTs, marketplace and a decentralized Domain Name System.Both services will be built on the Elrond (EGLD) blockchain, which is known for its ability to speed up transactions via sharding. ICI was founded in 1970 and is currently the most institution for government-sponsored research in the field of information technology in Romania. It currently supervises the Romanian National Register for Domain Names. As told by Elrond, the initiatives would be the first of their kind within the European Union. One use for the NFT marketplace would potentially be to digitize, access, transfer and store official documents, property deeds, or various certificates via a decentralized blockchain identity.Meanwhile, ICI seeks to leverage Elrond’s 3,200 strong network validators to overcome the security vulnerabilities of legacy DNS and TLD systems. Adrian Victor Vevera, general director of ICI Bucharest, commented:”Web 3.0 technologies can transform public administration and help its institutions and processes leap forward in terms of efficiency and speed while decreasing costs, overhead, and excessive bureaucratic activities.”Elrond claims its blockchain can process up to 15,000 transactions per second with six-second latency, is carbon-negative, and has negligible transaction costs. This was not Elrond’s first venture in Romania. Three months prior, the National Bank of Romania approved Elrond’s proposal to purchase Romanian fintech Capital Financial Services, also known as Twispay.

OpenSea announces migration to Seaport protocol

OpenSea announces migration to Seaport protocol

Uverejnil používateľ | jún 14, 2022 |

On Tuesday, OpenSea, the most popular nonfungible tokens, or NFTs, marketplace by trading volume, announced that it was migrating to Seaport. Among many perks, the protocol says it will feature lower gas fees, the ability to make offers on entire collections, removal of new account initialization fees, and more user-friendly signature options.As told by OpenSea, users would pay 35% less for gas fees when transacting on Seaport. Based on data from 2021, it would amount to an estimated $460 million (138,000 ETH) in total savings. In addition, the removal of the setup fee would potentially result in $120 million (35,000 ETH) per year in additive savings.The year prior, the Ethereum network became periodically congested due to celebrity NFT drops on OpenSea, with users reporting losses due to failed transactions. However, gas prices on the network have stabilized as of late. Average Ether gas prices tracked by YCharts have fallen to $95.86 compared to spikes of hundreds of dollars in 2021. OpenSea also teased features such as the ability to purchase many NFTs in a single transaction, making real-time creator fees available to multiple recipients, and defining fees on-chain on a per-item basis. Seaport listings have the same basic structure as previous ones while its developers worked in Assembly to optimize transaction efficiency.OpenSea does not control or operate the Seaport protocol and merely builds on top of it. Interestingly, the firm says it’s still “hiring across the board” in concluding comments. This is in contrast with steep rounds of layoffs announced by multiple cryptocurrency firms, including most recently BlockFi and Coinbase. OpenSea said that it does not control or operate the Seaport protocol and merely builds on top of it.
