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.

Agreed. Brave actually implemented this exact thing[1], and then got dumped together with other crypto scam projects, which continues to happen in this very thread.

Crypto haters are quick to shout that cryptocurrencies have no practical use, and introduce many problems, but this is a perfect use case for them. The negative discussion has detracted from some truly disrupting technologies being adopted, which is a damn shame.

Brave Inc. has made some missteps, sure, but I don't think they're overall an evil or scam company. A solution like BAT can eventually move us away from the current ad-infested web where advertising leeches serve as sleazy middlemen between users and companies, and scams and fake content flood the web in order to trick SEO and get easy ad revenue. The modern web is a minefield corrupted by advertising.

If browsers integrated with a decentralized wallet, that can either be filled by watching privacy-preserving ads OR by manually adding credit to them, had Humble Bundle-like sliders for users to control how much of their credit is allocated for each site, and the web had standardized APIs for websites to set their minimum price, then it would solve the monetization issue once and for all. The basic customer-business relationship would be preserved, where customers actually pay for the services they use, instead of the corrupt business models of today where web users are not even the customers, but a piece of rock gold can be mined from, and its value milked in perpetuity.

I think the single largest reason this hasn't happened yet is because it would negatively impact the profits of adtech giants who are running the web, and have a strong sway in directing its future. If any solution has a chance in getting mass adoption it needs to happen outside of the web, and be built from the ground up by avoiding the mistakes we now know have lead us to where we currently are.

minimum practical transaction size and cutting off the possibility for small casual transactions"

And more recently Brave, the browser tried to implement it.

"Crypto and DeFi are hard to use and the $330 billion digital advertising industry is failing users, publishers and advertisers. With Basic Attention Token and Brave we want to take Crypto to the next 1B users and solve the endemic inefficiencies and privacy violations hobbling the digital ad industry."[^2]

I personally think this is a beautiful idea, had it worked out as envisioned, the Internet could've been a very different and likely better place now. Pity cryptocurrencies came to be what they're in their present condition.

Basic Attention Token

Brave's Basic Attention Tokens, or BAT, are bridged across Ethereum and Solana per BAT's website; Ethereum previously used a proof-of-work model which had an awful environmental impact, but has since moved to a more efficient proof-of-stake model in September 2022, which the Ethereum Foundation claimed at the time would reduce energy use by 99.95%, though I can't find anything on the actual results. Solana as far as I can tell has only ever used proof-of-stake

As far as I know, it’s alright. Firefox (and some forks of it) are considered better with the right tweaks. Un-googled chromium and Brave are generally considered your best bets for a chromium-based browser (some sites unfortunately rely on chromium, though your mileage may vary). I think Brave is considered to be a bit more secure than un-googled chromium (don’t quote me on that)— but the trade off is that Brave has its own advertising platform with crypto (BAT Tokens) which you can opt out of, but is there nonetheless.

In the meantime, BAT can be used to tip your favorite sites/content creators online — more information on what you can do with BAT here: https://basicattentiontoken.org

As for content.. if you look at VRChat, you'll see that a lot of good content is created by the user base. Money could also be raised by buyers trying to profit off the coin. Many profit models to explore. For example Brave browser found a good way of integrating crypto with their BAT token.

There, I said it. Its only use case is tipping. They are pretty much a glorified version of moons, and not much better. Only about 10 million people regularly use Brave browser and there are about 1 million verified content creators accepting BAT (that's according to Brave themselves, so the actual numbers might be lower). That's... not a lot. There's about 150,000 moon vaults. I mean sure, that's less than a million. But as I'm writing this, moons have a market cap of 6.3 millions - and BAT has one of over 1.2 billions. That's impressively overvalued.
