arduino-cli VS chainlink

There's a vscode extension you can install that uses the arduino backend to compile and upload new sketches. You'll have to have the IDE/CLI already installed. If you want to avoid the IDE entirely I'd recommend the CLI available on github here and the instructions for the vscode extension can be found on circuitstate here. Good luck!

The Arduino folks also make the Arduino-CLI if you like typing at the shell like me: https://github.com/arduino/arduino-cli

> I'm sure you can still develop in VSCode with third-party plugins.

The Arduino IDE 2.0 uses the ArduinoCLI as backend and they comunicate through a gRPC API, most functionalities are implemented only in the latter. It's technically feasible to create a VSCode plugin. :)

> (To be honest though, I would have been happy enough if they built it in Emacs, even if similar objections apply.)

Never used Emacs but I think it should be doable to integrate the ArduinoCLI as a plugin, if you want to take a try at it I suggest you read the docs. The gRPC is still not 100% stable though, I made a big refactoring in the initialization steps recently that still needs to be merged.

I created some BitBake recipes to compile Arduino sketches using arduino-cli during a Yocto/Bitbake build. The (perhaps less convenient) alternatives would be to:

As well as feeding real-world data to smart contracts, oracles can be used to monitor other blockchains and pass information about them between networks. Chainlink has made progress in this direction, with their Cross-Chain Interoperability Protocol (CCIP). This enables the creation of multi-chain apps. The protocol is maintained by a decentralized network of nodes. However, this is unlikely to be as secure as the chains between which messages are being sent.

I do like the example of Etherisc as a simple showcase of what could be possible. It is a decentralised insurance platform, where right now you can purchase insurance against flight cancellations. Should the flight be cancelled a decentralised network Chainlinkreports to Ethereum the flight number and smart contract pays you out. Unlike traditional insurance (provided there has been security system of all systems involved) there is no way for the smart contract not to pay you out. With companies they can go bankrupt, argue against some technicality or have their own funds frozen due to clerical error.

We’d like to express our deep gratitude to Axelar, Chainlink Labs, Polkastarter, and Hacken for their generous support. We’re also proud to announce that our EU Incubator winners and participants, including Port3 Network, Blockless, Shorter Finance, and Dynamic Labs, will be joining us to share and sponsor bounties in our hackathon.

This is an example of my current work, though you have to go back in history a bit to see my name on the commits.

This is by no means an exhaustive list, just a smattering of some of the bigger projects doing neat things.

The graph protocol - decentralized blockchain indexing feeding a network of graphQL servers hosting the data powering dapps https://thegraph.com/en/

Chainlink - decentralized on-chain oracles for basically any piece of data from the real world - https://chain.link/

MakerDAO - creator of the first “soft pegged” stablecoin, it is a series of smart contracts that allow people to lock up crypto as collateral and mint DAI, uses a number of neat and novel mechanisms to keep peg by adjusting interest rates and incentivizing economic behavior https://makerdao.com/en/

Compound - a decentralized lending and borrowing protocol with no centralized authority handling liquidations/collateral pricing/etc. https://compound.finance/

Uniswap - a decentralized exchange for swapping assets in a trustless way, has neat features like flash loans where you can borrow a large amount of money (millions of dollars) for the length of one transaction, as long as the money is returned with a fee. This allows anyone to do things like capture arbitrage opportunities, liquidate large positions, or whatever else can be done in one transaction. https://uniswap.org/faq

A lot of these are DAOs using smart contracts to propose and vote on binding proposals on chain and adjust parameters within the protocol or paying contributors and whatnot. You can see an example here https://compound.finance/governance

Beyond that there’s other blockchains focused on specific use cases like GameFi, bridges connecting together different blockchains and moving liquidity between them in a mostly seamless way, massive research attention being paid to zero knowledge proofs (which have a lot of potential implications in the real world), and multi-sig contracts for only doing things when a quorum of key holders come together and signal their intent.

Chainlink A Oracle network for retrieving real-world data in a decentralized manner.

I have managed to complete the major part of the interoperability projects this year. I have been optimistic about Cosmos, Polkadot, and Chainlink, and I am becoming increasingly interested in the Bifrost network (layer 1). I've been reading the articles about their upcoming launch. The Bifrost network has introduced some features that other projects do not have yet. However,they are still unsure about the rewards for participating in the BIFROST BIT Testnet Reward Program as described in the article. This contributes to their goal of making the most of the Incentivized Testnet and ensuring that BIFROST is stress-tested and ready for mainnet. I still need to learn more about the Network and how it differs from the DOT and cosmos projects. I am interested in participating in the launch but still don't have any clear info and how to go about this.

Chainlink is currently ranked #23 cryptocurrency on CoinMarketCap, with a fully diluted market cap of $7.2 Billion. Chainlink was founded in 2017, and is the most powerful decentralized oracle in the crypto space. LINK has been rapidly integrating off-chain data and external price/data feeds within their smart contract platform. There are limitless use cases for this chain. Robinhood supports LINK buying, selling and deposits/withdrawals via the built in wallet.

If we wanted to inspect this AggregatorV3Interface aggregator contract, we could go to the following link and check it out => https://github.com/smartcontractkit/chainlink/blob/develop/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol As you can see, it has some functions like version, getRoundData, latestRoundData and so on. The thing is, we can import this aggrgator contract in our smart contract and actually use those functions in our smart contract.
