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.
Blockchains are quickly becoming the modern equivalent of what apps were to smartphones when they took off a decade ago. There’s a blockchain for everything - from cloud storage (Siacoin) to identity verification (Civic). But the original point of Bitcoin, the very cryptocurrency was to overturn the traditional banking system. An interestingly named token - Bread, is here to bring us back on track for this original goal. Bread technology intends to reinvent and revolutionize banking as we know it. By building a blockchain synced, Bitcoin-based wallet, the idea here is to decentralise banking and make it accessible to everyone. With a blockchain connected, easy to use Bitcoin wallet, Bread makes it easy for you to transition to a truly decentralised banking service.It also provides portfolio management tools to offer a comprehensive banking experience. Purchases made using its BRD token attract loyalty points and rewards, giving customers another lucrative reason to use the Bread wallet app. Bread was officially launched in 2014 itself and even raised VC funding to the tune of $7 million in August 2017. It then went the ICO route in December 2017, where it made available 88 million BRD tokens. $32 million was raised in the price, with BRD being valued at the rate of 900 for every 1 ETH at the time. As of June 2018, just over 6 months later, its value had fallen to above 1600 for every 1 ETH. A decentralised banking system was Bitcoin’s original vision that is either taking too long to fruition, or we’ve become an impatient audience. Whatever the case, Bread wants to accelerate the transition. A significant decision the Bread team took was to introduce the BRD token - which, with its cheap rates and loyalty/discount offerings, may emerge as the primary incentive for users joining the platform. If this is indeed the case, expect a spike in the value of the BRD cryptocurrency, something investors right now would be eyeing closely. Having said that, its fall in value since the ICO is certainly a cause for concern, and investors are advised to do their research and analyse before taking decisions.
