There are no hardware or utility requirements, as Ecos manages both, and the built-in profitability calculator can help estimate your earnings.


There are a variety of architectures for how the programs underpinning smart contracts are developed, distributed, managed and updated. They can be stored as part of a blockchain or other distributed ledger technology, and integrated into various payment mechanisms and digital exchanges that can include bitcoin and other cryptocurrencies.


Many platforms now allow for the use of smart contracts, including Ethereum, Hyperledger, Tezos and Corda. Today, with the growing adoption of bitcoin and the support of blockchain technologies, smart contracts are growing in popularity.


The first system was Bitcoin [69], which allowed users to transfer securely the currency (bitcoins) without a centralized regulator. In the blockchain network, miners are responsible for collecting transactions, solving challenging computational puzzles (proof-of-work) in order to reach consensus, and adding the transactions as blocks to the blockchain. Since then, several blockchain-based development platforms have been proposed offering the ability to host/ use smart contracts to execute automatically events and actions., namely NXT [71], Ethereum [16], Hyperledger Fabric [4], etc.


As we know, smart contracts are executable code hosted in the blockchain that store information, process inputs, and write outputs thanks to their pre-defined functions. They are used to improve data handling transparency, decentralize resource-constrained device management, and enable changes of the agreement terms at runtime while running on top of a decentralized and transparent network. In this category, we discuss resource-driven smart contract usage solutions, which can be categorized into data management-centric solutions (see Table 7), device management-centric solutions (see Table 8), and cloud-related solutions (see Table 9).


In cloud computing, both service requester and service provider agree on a set of requirements, obligations, and rights that is valid for the whole contract life-cycle. Recently, blockchain-enabled smart contracts have been used to enable changes in the agreement terms at runtime through the definition of conditions and actions. Table 9 presents some proposed cloud-related solutions [42, 84, 98, 118]. For instance, Zhou et al. [118] have proposed a witness model for enforcing cloud Service Level Agreement (SLA) using smart contracts. The game theory is leveraged to analyze that the witness has to offer honest monitoring service in order to maximize its revenue. The service provider needs to prepay fees to the smart contract for hiring witnesses. The service customer then decides whether to accept the SLA. If yes, it also needs to prepay fees including the service fee and its part of the hiring fee for witnesses. However, a small bug or attack on smart contracts can result in significant issues like privacy leakage or system logic modifications. Some of critical security vulnerabilities can include timestamp dependencies, mishandled exceptions, re-entrancy attacks on smart contracts in cloud-related solutions. 1e1e36bf2d
