In the presentation below, Brent Milliken, Ex-Head of BD Enterprise at Chainlink Labs provides an overview on the work Chainlink is doing to on-board traditional sectors to the burgeoning smart contract economy and change the way corporations are run in the near future. Here are some highlights from his talk. https://youtu.be/aZXscc46TN0?embedable=true What is Chainlink? Chainlink is the market-leading oracle network, helping secure hundreds of billions in DeFi and providing off-chain data and compute to thousands of dApps and DAOs. Initially launched in 2017, Chainlink decentralized oracle networks enable blockchains such as Ethereum and Solana, as well as applications on these chains, to securely connect to a wide variety of real-world data and off-chain computation. Linking on-chain environments with real-world data and systems helps to increase the possible use cases for smart contracts. Three Pillars of Digital Change Chainlink is providing services for applications supporting the three main pillars of digital change: digital information, digital assets, and digital agreements. Digital assets solve issues regarding ownership of real-world assets by introducing tokenization for storing value digitally. Digital agreements will be an important part of how traditional enterprises will start adopting smart contract technology, as corporations move towards using cryptographic proofs. These three pillars will fundamentally change the way corporations and many societal transactions  are run in the next few years. The world is moving from paper guarantees (probabilistic) to cryptographic guarantees (deterministic). Chainlink is being built to help make cryptographic truth the future of all reliable agreements. Smart contracts are becoming the dominant form of digital agreements. Even traditional industries are being reinvented on the blockchain. Some examples include the , and building a decentralized flight insurance platform. When comparing web2 and web3 technologies, having cryptographic truth assigned to those technologies is the main value proposition that blockchain technology can provide. As such, Chainlink is being built to help create a world powered by cryptographic truth and to become a universal standard underpinning digital agreements.

Some examples of how weak paper guarantees have negatively affected the public are Bernie Madoff’s , the , the , and Robinhood controversially on GameStop stock. Aside from these adverse situations, bank accounts, mortgages, insurance policies, and other important facets of the real world are still based solely on paper guarantees. infamous Ponzi scheme Wirecard scandal Enron scandal halting trading However, we are already seeing improvements with some of the trust-minimized applications that the CeFi (Centralized Finance) world is building. Chainlink provides cryptographic guarantees that are deterministic and definite. Unexplored Smart Contract Use Cases While DeFi is the most widely-known use case of smart contracts and oracles, Brent believes that the full implications and possibilities brought about by smart contracts are still not fully understood. If, for example, global TradFi markets start operating via hybrid smart contracts, the market for smart contracts would potentially be worth trillions of dollars. These markets include enterprise systems, asset management, tokenized carbon credits, payment rails (a payment rail is a payment platform that moves money from a payer to a payee, such as PayPal.), Central Bank Digital Currencies (CBDCs) like China’s digital Yuan, global insurance, commodities, real estate, capital markets, and more. According to Brent, it is only a matter of time before corporations start exploring the possibilities brought about by smart contract technology. Whatever application of smart contracts they end up using, Chainlink can provide data and computation to their smart contracts. Smart Contract Economy Oracles are a vital piece of blockchain infrastructure that will enable a feature-rich smart contract economy. High-quality data is needed for the growth of the smart contract economy. Currently, decentralized applications (dApps) like (a cryptocurrency wallet built for DeFi use) are highly reliant on oracles to function. High-quality data will become much more important to business cases in the future once traditional enterprises start onboarding to the blockchain economy. Reference contracts must be highly responsive, and have high-quality data as well as strong quality guarantees. These inputs are crucial for ensuring high-quality cryptographic guarantees. Metamask Services Powered by Cryptographic Truth introduces automated verification of reserves for dApps and other types of applications. One use case of it involves helping to verify the reserves of collateralized stablecoins. Stablecoins are typically backed one-to-one with fiat or other assets. Chainlink Proof of Reserve offers a verification service for the reserves of tokens used as collateral, thus providing the ability to verify if a stablecoin is truly collateralized as advertised. This helps reduce systemic risk across the protocol and the broader ecosystem, ultimately helping to protect users. Chainlink Proof of Reserve is also experiencing a huge increase in adoption. VRF functions as a random number generator on-chain, providing dApps with tamper-proof random numbers. Currently, VRF has many users across the crypto gaming and NFT industries. For example, randomness is required to ensure the NFT minting process is fair and every user has an equal chance at minting a rare NFT. Chainlink VRF generates and and is backed by a cryptographic proof, which is then delivered onto the blockchain. Chainlink Verifiable Random Function (VRF) computes randomness off-chain Another important service powered by cryptographic truth is cross-chain communication. The (CCIP) is being built to provide a framework for developers to build solutions that enable cross-chain token transfers, messaging, and other sophisticated actions across different blockchains and web2 systems. Cross-Chain Interoperability Protocol Case study: Tokenized Carbon Credits One exciting case study that Chainlink helps enable is through a collaboration with Greenworld, a non-governmental organization (NGO). NGOs are nonprofit groups independent of governments, organized primarily by private citizens. Greenworld has a product called A.I.R.S, in which farmers in Africa are paid to regenerate farmland. Once the farmland starts growing and thriving, satellite imagery can capture the change from a barren landscape to a regenerated forest. The Chainlink oracle gets this data  feed from satellite imagery. This collaboration adds to the many different combinations of use cases that oracles help to empower, providing a lot of excitement and hope for the industry. Accelerating enterprise adoption of smart contracts Chainlink is also accelerating enterprise adoption of smart contracts, which is a challenging task given that traditional enterprises are storing 20-30 years of data on legacy IT systems. Large enterprises will be able to utilize Chainlink as an to accelerate this migration. Enterprises can connect their existing data and systems on-chain through the services Chainlink provides. is one example of an enterprise adopting smart contracts with a real business case. They have worked with Swisspost to launch a . abstraction layer Swisscom 100% Swiss infrastructure for blockchain applications Chainlink was a Gold Sponsor of the inaugural Blockchain Oracle Summit: Berlin. BOS22 was the first conference to focus solely on the importance and design of oracles. Leading speakers from across the DeFi-TradFi spectrum came to Berlin to provide deep dives into their work using oracles to power exciting use cases of blockchain technology.

As the transmitters of truth on a blockchain, oracles are one of the most crucial aspects of technology’s next chapter. The goal of the Blockchain Oracle Summit is to bring builders, users and investors together, to accelerate growth in the oracle space. While scaling oracles to meet growing demand, careful attention needs to be paid to maintaining costs, decentralization, trust and more. Immutable blockchains need to be complemented by the most robust oracle networks.
