Association: Unobtrusively Creating Digital Contracts with Smart Products
Many business models for smart products, like pay-per-use, require that the smart product can digitally verify whether the user has a contract with the smart product and should be granted access to privileged functionality. Traditional means to do so, e.g. password login, are very obtrusive and can thus not be applied for smart product scenarios. In this paper, we present the mechanism of assoc...
متن کاملQuantitative Analysis of Smart Contracts
Smart contracts are computer programs that are executed by a network of mutually distrusting agents, without the need of an external trusted authority. Smart contracts handle and transfer assets of considerable value (in the form of crypto-currency like Bitcoin). Hence, it is crucial that their implementation is bug-free. We identify the utility (or expected payoff) of interacting with such sma...
متن کاملPlasma: Scalable Autonomous Smart Contracts
Plasma is a proposed framework for incentivized and enforced execution of smart contracts which is scalable to a significant amount of state updates per second (potentially billions) enabling the blockchain to be able to represent a significant amount of decentralized financial applications worldwide. These smart contracts are incentivized to continue operation autonomously via network transact...
متن کاملAdding Concurrency to Smart Contracts
Modern cryptocurrency systems, such as Ethereum, permit complex financial transactions through scripts called smart contracts. These smart contracts are executed many, many times, always without real concurrency. First, all smart contracts are serially executed by miners before appending them to the blockchain. Later, those contracts are serially re-executed by validators to verify that the sma...
متن کاملSmart Contracts for Bribing Miners
We present three smart contracts that allow a briber to fairly exchange bribes to miners who pursue a mining strategy benefiting the briber. The first contract, CensorshipCon, highlights that Ethereum’s uncle block reward policy can directly subsidise the cost of bribing miners. The second contract, HistoryRevisionCon, rewards miners via an in-band payment for reversing transactions or enforcin...
