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.
Standard Tokenization Protocol is a smart contract platform that allows issuers to create and issue token offerings in a regulatory compliant manner in a large number of jurisdictions around the globe. The protocol allows the integration of international regulations to enable compliant issuance of tokenized assets and cross-jurisdictional transfers of ownership. It also allows for issuer-specific parameters such as ownership concentration, holding periods, and voting. By issuing a permissioned ERC-20 token (STPT) on the Ethereum blockchain, Standard Tokenization Protocol ensures that: 1) regulatory and issuer-specific compliance requirements included in the smart contract are met at the token level, and 2) changes in the regulatory landscape can be captured and integrated. Standard Tokenization Protocol standard enables the tokenization of any type of asset in a globally compliant manner.
