# Metadata oracle node ## Problem statement Cardano metadata oracles (nut.link) are the first generation of oracles providing external data sources to the blockchain, that the developers can use. At the moment, there is no operator-friendly node, making it hard for people to participate. By having a node that can be easily run by multiple operators, we would achieve both higher reliability of endpoints and higher degree of decentralisation. ## Describe your solution to the problem We want to build an open-source, feature-rich, yet operator-friendly, node software. By doing so, we would lower the barrier of entry for new oracle operators and build the foundation of oracle pools. External data provided by oracles is critical for developers and is a major dependency for dApps creations on Cardano. You probably all know our proof of concept metadata oracles called https://nut.link/. At this time, we have five independent oracle operators that have provided more than 4 000 data points already! The nut.link metadata oracles has been featured in: * https://btcmanager.com/ergo-oracle-solution-cardano-ada-interoperability/ * https://ergoplatform.org/en/blog/2020-11-09-first-steps-towards-interoperability-with-cardano-oracles/ * https://www.youtube.com/watch?v=FaIk0sK-3Ps& * https://heraldsheets.com/ergo-unveils-oracle-solution-for-cardano-ada-to-enhance-interoperability/ ## Potential We would like to see more than 100 independent operators by end of this year, with datapoints consumed not only by wallets, but also by the dApps deployed within the Cardano ecosystem. But we need to start with an oracle node. ## Deliverables Within 2 months of receiving the funding, we will release the beta version, engaging with early adopters from the community. We will deliver the stable release within 4 months from the funding. Deliverables of the metadata oracle node are broken down below: * Support for metadata oracle registration and data posting * Data source definitions templates that are easy to share within the operators' community * Fetching and scraping of data with error handling and retries * Transaction construction, including dynamic fee estimation * Support for full local Cardano node (using `cardano-cli`) or remote API endpoint (lightweight metadata oracle client) * Prometheus style endpoint for monitoring and Grafana integration * Licensed under the open-source Apache License 2 We will maintain the project for at least a year and use project Catalyst in the future to extend it if there will be an interest from the community. ## Relevant experience We have experience with oracles on UTXO blockchains. We launched the first metadata oracle on Cardano, and we were the first community public oracle pool on Ergo blockchain. Five Binaries is an infrastructure development company. We're Cardano pioneers - with the first Cardano block minted on an aeroplane, first stake pool on the ITN and the first Shelley transaction on the mainnet. We are trusted by customers such as Emurgo, Trezor or Ergo Foundation. To get in touch or find more information about us, please visit https://fivebinaries.com/. ## Budget We estimate it will take us 200 engineering-hours to complete the deliverables and we plan to allocate three people to this project. 8 engineering-hours – planning, specification and administration 52 engineering-hours – engineering and development 6 engineering-hours – infrastructure and release 4 engineering-hours – testing and QA 120 engineering-hours – maintenance (bug fixes and security updates) phase for one year Our rate, which comprises of our engineers' salaries, infrastructure costs, office rent, accounting and taxes is 100 EUR per hour. We pay our people well, because they are both skilled and exceptionally experienced in the industry. And last but not least, because we respect them and want them to feel good and appreciated while working on Cardano.

Webdesign blockfrost.io

Ahoj, rádi bychom nový design pro https://blockfrost.io. Web má jen pár stránek. Všechny jsem popsal dole. Nechceme, aby ten web vypadal jako každý jiný web o kryptu. Mohlo by to mít 80s nádech. Nápady a věci, co se nám líbí. https://comma.ai/ https://hellonesh.io/ https://www.alchemy.com/ https://dribbble.com/shots/14938703-Coubra-Free-Font

Continuity token website

The project Continuity token is a digital asset that provides a backup solution to our other digital assets such as NFTs. When you hold the Continutity token in your digital wallet, we make sure to backup all your media that are inside this wallet in different ways. Structure of the website Top bar Will have the links to different sections of the landing page. "Home", "About" "Plans" "Team" "FAQ" and a button to the right "Verify your wallet". Also, it will include logo of the Continuity Token (not yet created)

Design What is the name of your company or project? Don’t have a name yet? We can help. Five Binaries is the company. Blockfrost is the product. State a word or phrase that describes your product / company. It's an API for Cardano decentralized blockchain. Accessing and processing information stored on the blockchain is not trivial. We provide abstraction between you and blockchain data, taking away the burden of complexity, so you can focus on what really matters - developing your applications.

Happy new year 2023 and thank you for being with us! Without your support in 2022, we wouldn't be able to provide free infrastructure to thousands of developers and lower the entry barrier for building your ideas on Cardano. Last year was extremely challenging. We were tackling unprecedented problems and spent many sleepless nights solving these conundrums. We estentially redesigned, iterated and rebuilt Blockfrost several times during this period. All this had to be done in parallel and on the fly. Many of you have felt the impact, be it the temporary negative or the permanent positive one. We would like to thank you for all the feedback, critisism and praise to learn from. We are still miles from what we want and can provide, but we're walking the walk. Obviously, this is just the start. 2023 is going to be even more challenging, but we are commited more than ever before to deliver the initial promises and being here with and for you as a part of this amazing community.
