News, Success Stories

by Marketing Team

Blocksize Capital is pleased to announce that we are extending our successful collaboration with Chainlink—the leading decentralized oracle network in the blockchain industry. Blocksize Capital has been a node operator on the Chainlink Network for some time. We are now deepening this successful collaboration and expanding our integration into the Chainlink ecosystem by becoming active as a data provider, supplying reliable market data to the Chainlink Network and its vast collection of Sybil-resistant node operators.

Developers can now use Blocksize Capital’s aggregated market data to support a wide range of smart contract use cases, including options and futures products, yield products, prediction markets, algorithmic stablecoins, and more. By making our data available to the blockchain economy, we’re also opening up a new and growing revenue stream.

We chose to expand our integration with Chainlink and bring our data on-chain through an official Chainlink node because its decentralized oracle network is secure, future-proof, and is the industry-standard solution for connecting data providers with smart contract developers. This expanded Chainlink integration stands as a part of our commitment to building a world based on cryptographic truth and increases the value that being a part of the smart contract ecosystem brings to our firm and our partners.

Blocksize Capital offers professional digital asset trading infrastructure solutions, empowering financial institutions with cutting-edge technology that enables them to embrace the transformation of finance and capital markets through the new wave of digitalization. Our solutions are enterprise-grade terminals for securing, trading, and supporting investments in digital assets. Through a team of experienced financial professionals with extensive know-how in cryptography and distributed ledgers, we are transforming and improving financial infrastructure.

We chose to expand our collaboration with Chainlink because it provides a multitude of critical features, such as:

  • Credential Management — Chainlink nodes can securely manage API keys and account logins, leading to a seamless integration in which Chainlink nodes can purchase Blocksize Capital API subscriptions in the same manner that traditional users do today.
  • Blockchain Agnostic — Chainlink is blockchain agnostic, meaning our data can be made available on any current or future blockchain environment.
  • Widely Adopted — Chainlink is the most widely used oracle network in the blockchain industry, offering us access to a vast addressable market of potential data consumers.
  • Provably Secure — Chainlink is thoroughly audited open-source software designed according to leading academic research, already proven to secure billions of dollars in value live in production.

“We are excited to extend our integration with Chainlink by becoming a data provider on the network. By becoming a data provider on the largest decentralized oracle network in the blockchain industry, we’re able to deepen our footprint in the expanding DeFi economy, open up a new revenue stream through the monetization of our premium market data, and help power smart contract innovation and the adoption of cryptographic guarantees in financial agreements.”

Christian Labetzsch, Managing Director of Blocksize Capital
