Smart contracts on Ethereum are fully self contained and any information or access to off-chain data is restricted. Tellor solves this problem by creating a system where parties can request the value of an off-chain data point (e.g. ETH/USD) and miners compete to add this value to an on-chain data bank, accessible by all Ethereum smart contracts. Inputs to a data series are secured by a network of staked miners. The main Tellor smart contract creates a time series of each requested data series and aims to become the standard source of high value data for decentralized applications. This oracle, “Tellor”, utilizes similar incentive mechanisms to other cryptocurrency systems through the issuance of Tellor’s token, Tributes, that are used to request a particular data series from miners.
A high-throughput, DAG-based protocol capable of powering any application. Wavelet | Wasm smart contracts powered by a high-speed ledger. We utilise our unique Wavelet probabilistic DAG-protocol mechanism to facilitate over 31k+ transactions per second and 0-4 second time to finality. What is Wavelet? Wavelet is Perlin’s directed acyclic graph (DAG) based protocol. It is a base-layer ledger which means anyone can build any type of application. It is designed to be the fastest, most secure, and most scalable distributed ledger solution in existence today. Wavelet is underpinned by a new and leaderless proof-of-stake consensus model (LPOS). One of our first use cases for Wavelet is international trade and commerce. Wavelet is well suited for increasing efficiency and transparency for complex processes (that have many inputs and output) such as supply chains and international commerce. While our first commercial focus is bringing Wavelet to the international trade and commerce arena, it is a very flexible protocol and can facilitate a myriad of use cases. Building on Wavelet is designed to be super easy, and we encourage experimentation. If we identify promising real-world applications built on Wavelet, the Perlin team will provide grants and support to facilitate commercial success. Get started here: https://www.perlin.net/
