Decentralized oracleoracle provider Chainlink is expanding beyond the Ethereum blockchain, which it’s targeted up to now. The startup’s solution for secure, transparent and accurate data feeds has now been adopted by blockchain interoperability platform Polkadot, according to an announcement on Tuesday.
Developers building on the Polkadot protocol will now be able to rely on Chainlink’s oracles to securely access “virtually any external, real-world resource,” the announcement said.
Polkadot plans to use Chainlink’s decentralized oracles for its “parachain” technology, which acts as a bridge between different blockchains. Oracle-sourced data will provide key information such pricing feeds and will be used to verify identity-based digital signatures, according to the announcement.
Initially, the oracle technology is being integrated for Substrate, Polkadot’s blockchain framework. Chainlink’s oracles will roll out to all Polkadot’s Substrate-based chains. Polkadot is also working to introduce it on its experimental network, Kusama, and eventually the whole network, said the announcement.
Chainlink diversifies its reach
Launched in 2016 by Ethereum co-founder Gavin Wood, Polkadot becomes the first non-Ethereum blockchain platform to integrate Chainlink. The oracle provider is fast diversifying its reach, and has been working with large enterprises, such as Google and Swift.
Out of all the cryptocurrency projects that made rapid progress in 2019, Chainlink (LINK) has emerged as one of the clear leaders.
Not only has the decentralized oracle provider outperformed the entire altcoin market, it’s even outpaced Bitcoin on a number of occasions, and many investors are confident that 2020 will bring further gains.
But that’s not the news that most excites Chainlink CEO Sergey Nazarov. Speaking to Decrypt, he highlighted three key reasons why Chainlink will continue to...
Most recently, Chainlink announced a raft of integrations in Decentralized Finance (DeFi) applications, including no-collateral loan company Aave. Its oracle networks are primarily being used to provide accurate price feeds from off-chain sources.
Chainlink’s $40,000 error
But last Friday saw Chainlink experience a serious problem for the first time. An error occurred with a price feed, allowing some eagle-eyed users to make around $40,000 worth of profits within a short period of time.
The XAG/USD Chainlink price feed was incorrect for over 6 hours yesterday. Someone made $6.8k in profit due to this error. https://t.co/yP9Kr6iEr2
The feed registered the incorrect price for silver-to-USD (XAG/USD) on Synthetix, a platform for trading Ethereum-based DeFi derivatives, which uses price feeds from Chainlink.
In a blog post, published after the event, Chainlink asserted that the issue was not with the oracle technology, but was the result of human error. Node operators servicing the XAG/USD oracles incorrectly requested a price for gold rather than silver, the oracle provider explained.
When Netflix quietly announced plans to remove “Bandersnatch”—the groundbreaking interactive episode from Black Mirror—futurist and journalist Katie Schultz launched a campaign to preserve what she calls a pivotal moment in streaming history.
Outraged at what she saw as the quiet erasure of a significant chapter in streaming innovation, Schultz launched a Change.org petition to preserve Bandersnatch—and within days, it gathered more than 6,500 signatures from show supporters.

Brazil might pull the plug on popular chat app Discord after a failed terrorist attack at Lady Gaga's mega-concert revealed the platform was used to plan violence against LGBTQ+ attendees.
Brazilian Deputy Guilherme Boulos formally requested Discord's suspension last week, just days after police foiled a plot to attack Lady Gaga's May 3 show at Copacabana Beach—a massive event that drew over 2.1 million people. Authorities conducted their "Fake Monster" operation across four states, executing 15...
People are being tricked into downloading fake AI tools as a way to spread the information stealer malware Noodlophile.
This malware is able to harvest browser credentials, cryptocurrency wallet information and more sensitive data, according to a security researcher.
Morphisec researcher Shmuel Uzan said, in a report, "Instead of relying on traditional phishing or cracked software sites, they build convincing AI-themed platforms – often advertised via legitimate-looking Facebook groups and viral...
