About Witnet

Witnet is a project originally devised by Stampery, a company focused on blockchain-driven data certification. The protocol is now being developed by Witnet Foundation in collaboration with a community of independent contributors. The mission of Witnet Foundation is ensuring the successful development and deployment of the Witnet protocol, and guaranteeing its sustainability and fostering the ecosystem of applications built on top of the protocol. Although Witnet Foundation will play a chief role during initial years, as the project evolves and the Witnet community becomes wider, Witnet Foundation will progressively relinquish its influence in favor of the community.

Tomás Ruiz on the Standardization of Oracle Networks, its Challenge, and Call To Action

Dec 28, 2022

Too Long; Didn't Read Witnet is a multi-chain decentralized oracle network (DON) that focuses on connecting smart contracts to online data sources in a secure and trustless manner. The Alliance of Decentralized Oracles (ADO) was formed by a group of oracle protocols with the aim of creating standardized plug-and-play oracle use for developers. People Mentioned Blockchain Oracle Summit In the presentation below, Tomás Ruiz, technical lead of Witnet, presented on the importance of standardization for oracle networks, the challenges of implementing them, as well as his proposed solutions to these issues. Below are some important points to note from his presentation. What is Witnet? Witnet is a multi-chain decentralized oracle network (DON) that focuses on connecting smart contracts to online data sources in a secure and trustless manner. It is a  layer-1  protocol, which means that it operates as its own blockchain. The protocol features a network of  nodes  called “witnesses” that are incentivized to provide data to smart contracts with  Wit tokens . Wrongdoers or dishonest reporting is punished by having a percentage of their staked tokens “slashed” – taken away – in order to maintain a high quality of data reporting. Witnet is also a “parametric oracle”, which means that users are able to customize their data requests using a domain specific language called RADON, and consume data from any public  API  of their choosing. For more information on how to request public APIs on Witnet check out  this section  in their documentation. When the team started building Witnet, they intended for it to be blockchain agnostic. Blockchain agnostic solutions are protocols that are compatible with any blockchain network. Witnet focused on building a chain agnostic solution because they believed that the world was moving towards becoming more decentralized and “multi-chain”. Witnet is currently available on Ethereum, Celo, Metis  and more ! However, back in 2017 when Witnet was being built,  cosmos SDK  and  substrate , which are open source frameworks for building custom, interoperable blockchains, did not exist. Consequently, the Witnet team had to spend 2 years developing their entire platform from scratch. Why Create A Standardized Interface for Oracles? In order to streamline the user experience, the Witnet team wanted to develop an oracle solution that would be easy for smart contract developers to use. In order to achieve this, the team wanted to build out a standardized interface that allowed developers to implement Witnet in the exact same way that other oracles were being used. However, the team found that there was no common method of consuming oracles. Instead each oracle had vastly different ways of operating. According to Tomás, implementing a standardized interface for oracles would bring about many benefits. Other than improving the overall developer experience, implementing common standards for oracles will facilitate greater  composability , which allows developers to reuse existing software modules to create new systems. Developing a standardized oracle interface would also provide the opportunity for industry players to discuss and address inconveniences related to oracle use, this strengthening one of the most important layers of the Web3 ecosystem. Alliance of Decentralized Oracles (ADO) The Alliance of Decentralized Oracles (ADO) was formed by a group of oracle protocols with the aim of creating standardized plug-and-play oracle interfaces in order to streamline oracle use for developers. The group, which is open to anyone interested in decentralized oracles, includes representatives from Witnet,  Tellor ,  BAND protocol  and  iExec  among others. In 2020, ADO decided to implement a new standard, called  EIP-2362 . Unlike previous standards that were not successfully implemented, the EIP-2362 standard did not focus on how oracles should behave. Instead, it focused on how the interface would be used by developers and, according to Tomás, is extremely easy to implement and follow. For more information on the EIP-2362 standard, check out  this public demonstration  of the standard, featuring Witnet founder Adan Sanchez, Tellor co-founder, Nicholas Fett, BAND Protocol co-founder Paul Nattapatsiri and Hadrien Croubois, ex-research engineer from iExec. The demonstration details exactly how to integrate EIP-2362 into existing projects and smart contracts. Implications of The Blockchain Trilemma on Oracles The Blockchain Trilemma is a term coined by Ethereum founder, Vitalik Buterin. It describes a common challenge faced by developers, where they are forced to make trade-offs between security, scalability and decentralization when building a blockchain network. It is almost impossible to achieve an optimal level of all three components on one blockchain. Similarly, oracles are also constrained by the same trilemma. For example, an oracle that prioritizes decentralization & scalability, will be less secure than an oracle that is focused on security & scalability. However, it will be less decentralized than the former. In his presentation, Tomás reiterates the importance for protocols implementing oracle solutions to thoroughly research the available oracle solutions and the various features and trade-offs being made. Depending on the different trade-offs made, each oracle would be better suited for different use cases. Therefore, it is imperative that developers are fully aware of the exact trade-offs being made in each oracle solution being used. This presentation  by Sasa Milic provides some insight into the differences between some of the more well-known oracles like Chainlink, Tellor and UMA. According to Tomás, it is also important to always assume that your oracle can fail. Being aware of the specific trade offs will help users to make more educated decisions and implement suitable solutions in case of an oracle failure. Check out  Liquity’s presentation  on their dual oracle design that has sparked lively discussions in the space about possibly introducing new industry standards for oracle use. Looking Forward Oracles are a cornerstone to DeFi, and many other blockchain use cases. Due to their significance to the entire ecosystem, should oracles be made a public good? Should the industry be looking for ways to sponsor or subsidise data requests & oracles? As explained by Tomás, this is a problem that is yet to be solved. A lot more discussion and collaboration is needed in order for the entire industry to move closer towards achieving more robust oracle solutions, and educating end-users on the proper implementations of these protocols. The Blockchain Oracle Summit was the world’s first conference to focus solely on the important role that oracles play in the wider blockchain ecosystem and their limitations. Leading speakers from across the world gathered in Berlin to share their work and experience building and using oracle solutions. Find out more about Witnet:
