hera VS chainlink

Argo Labs now features Hera Workflows! Hera is a very simple Python library for constructing workflows - it can run any Python script you submit, allowing you and your company to focus on the value of the script itself rather than workflow construction :) you can run anything! ML workflows, DevOps jobs, crons with API calls, ETLs using pure Python, containers with commands, easily integrate with things like Horovod, etc.

Chainlink (LINK) – The Blockchain Oracle Giant

Chainlink allows smart contract developers to receive a wide variety of off-chain data, with the most commonly used features being receiving off-chain randomness and off-chain pricing data. Integrating your smart contracts with Chainlink provides a unique set of potential security vulnerabilities that attackers can exploit; here are the common vulnerabilities that smart contract developers & auditors need to look out for.

In some way, I'd also put Chainlink in that category since they allow to access open world data on-chain and making dapps more relevant as a result.

Smart contracts have revolutionized various industries by enabling the automation of agreements and transactions in a secure and decentralized manner. However, for smart contracts to reach their full potential, they need access to real-world data and external systems. This is where Chainlink comes into play.

I would suggest the use of an oracle like chainlink. Link: https://chain.link - I don't know exactly what your specific requirements are since I cannot review your code but a thirdparty oracle sounds like it could offer you at least some direction.

🥁 Introducing Co:OPERATE @ EthCC by Celo with Co:HOST Chainlink!

Etherisc has built a platform (Generic Insurance Framework) for decentralized insurance applications. We use blockchain technology to help make the purchase and sale of insurance more efficient, enable lower operational costs, provide greater transparency into the industry and democratize access to reinsurance. We’ve been around since 2016, have many high-profile collaborators (including Chainlink) and are proud of the innovative applications of the parametric insurance products built on our platform, including travel delay, crop and carbon credit protection.

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.

Chainlink is not a blockchain - it's a "heterogeneous network", i.e. an open-source protocol for building oracle networks. Chainlink is 'blockchain-agnostic', aimed at connecting any chain to any API/external system and supporting interoperability between chains. Besides ETH, it has existing or planned integrations with: ONE, ADA, XTZ, MATIC, HBAR, DOT, BSC, ATOM, LUNA, etc.
