Nifty Royale Will Integrate Chainlink Keepers to Automate NFT-Based Battle Royale Games



Nifty Royale is delighted to announce our plan to integrate Chainlink Keepers to fully automate our NFT-based battle royale games in a decentralized and highly reliable manner. Chainlink Keepers is a decentralized service that calls smart contract functions when specific conditions are met. In the case of Nifty Royale, Chainlink Keepers will trigger the execution of elimination rounds after pre-defined periods of time.

We decided to outsource the management of this particular function to Chainlink Keepers because they are operated by the same nodes that service Chainlink Price Feeds, which currently secure tens of billions of dollars in value for leading blockchain projects. Knowing our battle royale games can be fully automated with the highest uptime guaarantees makes our platform more secure and frees up our development team to expand the value it provides to users.

finance.vote Integrates Chainlink Keepers to Automate and Decentralise Settlement of markets.vote

We are excited to announce that finance.vote has integrated Chainlink Keepers live on the Ethereum mainnet. This integration supports our previously announced integration of Chainlink Price Feeds by creating a fully automated and decentralised process for settling financial prediction markets on the markets.vote dApp.

Each markets.vote prediction market starts at midnight UTC and ends exactly one week later at the same time. Right when one ends, a new one begins. These prediction markets allow users to stake tokens and then vote on which coin out of a curated list of ten will grow the most in terms of price percentage against the U.S. dollar. If a user votes on the winning token, they win a share of a network-generated rewards pool.

markets.vote prediction markets rely on Chainlink Price Feeds to get a volume-weighted global price for each of the ten tokens at the start and end of each prediction market, which is Sunday at midnight UTC. This gives prediction markets an accurate and tamper-proof starting and ending price to then calculate the change over the seven day period.

Quantum Data Technologies to Launch Chainlink Node to Bring AI-Based Crypto Price Predictions On-Chain

We are pleased to announce that QDT will be launching our own Chainlink node to make our premium AI analytics and predictions for crypto available to developers building on various smart contract platforms. Chainlink is the industry-leading secure blockchain middleware for getting existing APIs compatible with blockchain networks. Through our Chainlink node, we can broadcast our data and predictive analytics directly onto leading blockchains, as well as cryptographically sign our data to provide on-chain proof that it originated from the QDT API.

Developers will be able to call the QDT Chainlink node to get daily BTC price predictions that have been generated through specialized AI and ML deep learning algorithms. These signals can be leveraged by developers to automate new data-driven smart contract applications on blockchains, particularly useful for institutional traders and investors. For example, developers can create on-chain trading strategies that trade BTC or that rebalance portfolios based on crypto price prediction forecasts. This gives users the ability to make real-time decisions in an automated manner using time-tested signals.



What does QDT’s collaboration with Chainlink mean for the future of Finance?

As mentioned, one of the major challenges faced on the blockchain is the onboarding of off-chain data. While our initial scope is to bring BTC price prediction signals onto the blockchain, the larger vision is to offer our extensive library of off-chain data to smart-contract developers.

Our Data Lake has 150,000+ unique sources from the following categories:

Alternative – e.g. Apple Mobility, Airport Traffic, COVID case and death rate
Bonds – e.g. Treasuries, Government Bonds, Overnight Rate
Commitment of Traders – e.g. Hedge Fund positions, Long/Short, Spreads
Commodities – e.g. Energy, Industrials, Agricultural
Cryptocurrencies – e.g. Bitcoin, Ethereum, Binance Coin
Currencies– e.g. USD, EUR, YEN
Equities – e.g. NYSE, Nasdaq, London Stock Exchange
Fundamentals – e.g. Car Production, Oil Production, Housing Index, Import/Export
Indices – e.g. Equities, Commodities, ETFs
Interest Rates – e.g. Gov, Corp
Macroeconomics – e.g. GDP, Unemployment, Inflation, Gov Debt
News – e.g. Headlines from 170 different news sources (Bloomberg, API Newswire, Thomson Reuters, etc.)
Shipping – e.g. Freight Rates, Vessel Tracking, Vessel Types
Technicals – e.g. Moving Averages, Bollinger Bands, Oscillators
Weather – e.g. Precipitation, Wind, Temperature

Our aim with Chainlink is to make this vast array of data available across the blockchain. Our goal is to dramatically broaden the scope of available data categories and types, and set the stage for huge growth and mainstream adoption of the DeFi ecosystem.

Prophecy chooses Chainlink VRF for Prophet Pools

The next evolution in verifiably fair dApps with Prophecy — rapid yield generation in a new, gamified vision.



We’re excited to announce that Prophecy, a DeFi and NFT-focused ecosystem of dApps and services, has integrated Chainlink Verifiable Random Function (VRF) across our flagship product — Prophet Pools. This comes as part of our commitment to building out the most revolutionary yield-generating product, with a focus on provable fairness and randomness in an engaging and exciting service.

By integrating Chainlink’s industry-leading decentralized oracle network, Prophecy now has access to a tamper-proof and auditable source of randomness needed to select Prophet Pool winners in a fair and secure manner. Ultimately this creates a more exciting, transparent, and fraud-proof user experience, as users can participate in individual Prophet Pools with strong assurances that the winners will be chosen with integrity and fairness. We’re humbled to be pushing forwards with ethical decentralization in a manner that puts supporter confidence first.

Chainlink VRF works by combining block data that is still unknown when the request is made with a user-supplied seed and the oracle node’s pre-committed private key to generate both a random number and a cryptographic proof. Prophet Pool smart contracts will only accept the random number input if it has a valid cryptographic proof, and the cryptographic proof can only be generated if the VRF process is tamper-proof. This provides users with automated and publicly verifiable assurances directly on-chain that using Chainlink VRF for randomness is provably fair and cannot be tampered with or predicted by the oracle, outside entities, or the Prophecy team.

Genshiro Integrates Chainlink Price Feeds In Its NFT Tokens

Genshiro is going to release a limited run collection of NFTs featuring cats pertaining to different cryptocurrencies. BTC, ETH, DOT, KSM, GENS, and EQ will all be represented here, and they’ll be available for sale on Rarible, the well-known NFT marketplace. All the money raised from the NFT sale will go toward covering our operational costs, primarily funding our bid for the Kusama parachain auction.

These NFTs are issued on Ethereum and come with a fun feature that depends on the real-time prices of these various cryptocurrencies. By way of the Chainlink integration, when the underlying assets cross a certain price threshold — when BTC crosses $100,000, for example — it unlocks a golden version of each cat NFT. Our Genshiro cats are like trading cards that can change appearance based on real-world price data!

In support of open-source development, we are proud to join the upcoming Gitcoin Grants Round 10 as a matching partner. Our financial contributions will go towards the development of Ethereum infrastructure that the Ethereum community has deemed most important via Gitcoin’s quadratic funding model. By democratizing funding, Gitcoin incentivizes developers to build key infrastructure and tooling such as open-source programming libraries, lightweight Ethereum clients, new Ethereum 2.0 implementations, more reliable monitoring tools, new testing suites and deployment tooling, and more. Gitcoin also provides financial compensation via open-source grants for the maintenance of highly critical existing infrastructure to ensure Ethereum dApps remain secure and operational at all times.

Democratizing Financial Support for Ethereum Developers

Very happy with LINK's development, luckily I held it for more than 3 years when I bought it for around $0.3, I'm sure Link's performance will continue to improve and there are no plans to sell this year.

DFX Finance Integrates Chainlink Price Feeds to Secure Forex-Based Automated Market Maker



The DFX AMM is designed specifically for forex and is not a generalized AMM. This new AMM is uniquely built for low volatility trading of currency pairs. We are working with stablecoin issuers in various countries covering multiple continents to provide access to domestic markets with local on/off-ramps. We leverage an oracle powered by Chainlink to provide external FX price feeds into the pricing engine.

The oracle design is very powerful. The oracle does not dictate the price, but rather provides a reference point for the bonding curve. This optimally shifts capital along the range of the bonding curve without any user intervention.
