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.
OneLedger enables you to focus building your business application through OneLedger modularization tools, which will communicate with OneLedger protocol using its API gateway. This mechanism will make your business application interact with different public and private blockchains synchronously through corresponding side chains implemented in OneLedger platform. OneLedger defines a three-layer consensus protocol to enable more effective integration of different blockchain applications. Business logic can be implemented by the first layer – a configurable role-based consensus protocol leveraging hierarchical grouping similar to the structure of Merkle Tree. The side chain consensus protocol can move consensus traffic from the main chain with public consensus to the side chain with high performance and efficiency. OneLedger block structure enables the synchronization and reference between the three-layer consensus. The company works as a cross-ledger blockchain platform for people to make exchanges through business methodology. Not only that, but it’s also developed using the enterprise blockchain technology solutions that are running across the globe like something the world has never seen. One Ledger also operates as a powerful consensus engine that will help people with governance, so they can rest assured their transactions are being completed legitimately. The SDK on the platform is also highly customizable. And the platform, in general, is highly scalable and reliable. The architecture of the One Leger is built around the focal point of building your business software through the One Ledger modularization tools. They are set up to communicate with One Leger’s advanced protocol via the unique API gateway used by the platform developers. The new method of operation is designed to make your business application work together with different private and public blockchains in synchronicity by way of side chains that work together and are implemented via the One Ledger platform. The platform is designed to help people in a wide range of different business models. People in finance, agriculture, transportation, manufacturing and just about anything else will benefit highly from the One Ledger protocol. It works with Bitcoin, Ethereum, HyperLedger and several other platforms.
