My #API3 Thinkathon 1.0 idea: Stablecoin Black Swan Protection, using #API3Alliance members

  • @finageltd, fixer.io, @currencyfreaks, exchangerate-api.com in a Forex dAPI, and
  • @FTX_Official, coinlayer by @apilayer, and @KaikoData in a stablecoin price dAPI.

The product would check to ensure a deviation of > a volatility threshold % in the value of the transacted stablecoin hasn’t been surpassed, in the comparative price of a basket of similarly pegged stables, and in forex compared to another “baseline” fiat currency.

This would safeguard against high volatility in the (i) pricing/valuation of the stablecoin being transacted and (ii) the fiat currency to which the stablecoin is pegged. High-demand protections if smart contracts are to be used for high-value and longer-term-locked transactions.

By calling the dAPI interfaces before stablecoin payment, the Forex dAPI & stablecoin price dAPI responses would ensure the stablecoin price and relative fiat price are not a certain amount different (volatility threshold) than the initially agreed price.

The stablecoin could also potentially be compared to $RAI volatility, or the contract could hedge the volatility with derivatives via #API3Alliance members @DeribitExchange’s & @KaikoData’s data. This can address local hyperinflation and stablecoin regulatory/exploit risks.

Create an ecosystem made up of multiple and diverse ONGs dedicated to helping immigrants in North, Central and South America (or the entire world). This ecosystem can with the help of the blockchain manage in a transparent and decentralized way the resources and statistics destined to help immigrants and in this way everyone who wishes to donate to the cause can track the organizations which would generate more trust and motivate others to collaborate. At the same time the staff of the ONGs is selected and trained and they are responsible for creating educational programs so that people (immigrants) have the opportunity to learn about web3.0 technology and can create a better life, thus spreading knowledge. The creation of a database in blockchain favors the formation of a platform that selects from among migrants human talent capable of working for API3 or any of its partners.




A Public Record of Individual Carbon Offsets

There is a pressing need for accelerated investment in strategies to reduce rising greenhouse gas (GHG) levels due to their strong effect on the global climate. While there are numerous approaches individuals can take to reduce emissions, reaching carbon neutral is difficult. Carbon offset is an approach to compensate for emissions through initiatives such as renewable energy development, GHG capture and/or destruction, and reforestation.

ClimateKuul is an existing API3 data provider with endpoints for calculating the carbon footprint of travel by air and road. This functionality could be incorporated into a dApp that enables individuals to calculate the carbon footprint of their travel activities and, utilizing the verifiable nature of the blockchain, demonstrate a public commitment to offsetting those emissions through cryptocurrency payment to validated carbon offset entities. Growth in users publicly committing to carbon offset could spur new, globally distributed entrants with creative solutions to tackling GHG emissions.

This idea of public commitment to carbon offsets could even be extended to one’s participation in the blockchain itself. While it would require numerous assumptions e.g. the energy source composition of electricity consumed by blockchain miners, it is not unreasonable to envision an API3 data provider calculating the emission cost of blockchain transactions for a given address.

A suite of complex RNG dAPIs using standard off-chain RNG APIs
(random number generator = RNG)

Germany lost World War II due to a lack of sufficient randomness. The Enigma machine used by Nazi Germany to encrypt messages used in the war was cracked by the British Bombe. Given enough time, the machine developed by Alan Turing exploited the Enigma machine’s cryptographic algorithm and cracked the encryption. I blame all of this on the lack of randomness (and hence the predictability) of the enigma machine.

Trying to code (true)randomness into a deterministic system is probably impossible, however, getting as close to it as possible is also absolutely essential. Many anons have similarly faced the issue and abuse of having to play a rigged game in the past couple of months. I’m talking about generative art NFTs of course. The vast majority of generative art NFT projects that I have tried to mint faced significant challenges in terms of being able to retain fairness/randomness around the minting process. We often see people attacking the non-randomness of a lot of these generative processes with bots and algorithms and compromising the fairness of the distribution process. You might want to say that it doesn’t really matter, who cares what piece of art you happen to generate and if someone else can game the system, right? However, at the same time, you can’t deny the importance of random numbers in creating truly fair distribution models, and yes you might want to write off that importance for some random (pun intended) NFT project, however, the importance of NFTs, their use cases and the narrative around their utility/value is increasingly undeniable.
The ‘metaverse’ is just one of those increasingly undeniable narratives/utilities. On-chain multiplayer games with Battle Royale modes (Floor loot RNG etc.) and on-chain MMORPGs (quest rewards RNG) are coming, they’ll need increasingly better and secure RNG sources. Not to mention all of the chance related games. You can even add non-NFT related implementations like chance-based games (fair lucky draws, lotteries, Russian roulette-style games etc.) and even dApps like tornado.cash to add privacy/security layers on transaction paths etc.

There are many RNG APIs available off-chain, I would like to see a dAPI implementation that combines 5 or more of them to create an on-chain RNG API source. I’m not technically proficient, but my inept understanding would be, adding a few layers of calculative processes (multiplying/dividing/squaring) and some random sequencing among the off-chain RNG APIs, or something along those lines. I suggested a suite of these dAPIs, tailored for different use-cases and priced respectively, so the more complex it is, the more it can (and should) cost, but also simpler/cheaper solutions for simpler/cheaper use-cases.
(I know VRF exists. I just think dAPIs are plausibly better solutions, add the insurance aspect on top and mind-blown)


Hello Everyone!
Quick submission on this subject guys.

Expanding a bit on the whole ecosystem idea and potential future implementations, guidelines specify theoretical ideas using the API3 protocol and existing data providers; but ever since hearing about API3 and Airnode, I´ve had my target set on expanding the data providers ecosystem to data generators who are unaware they could be providing data to other projects or initiatives, through the blockchain, not necessarily on-chain smart contract applications only.

For example, through Airnode and API3 implementations, academia and research could benefit from useful, remotely generated, realtime sensor data, which could be monetized more easily and made more accessible to other researchers, for example, publishing papers on subjects such as changing climate patterns around the globe.

All this enabled thanks to easily deployable, maintenance-less Airnode nodes, monetized and insured through the API3 protocol, potentially governed under their own research applications specific sub-DAO.
