New research from a team of MIT engineers has found an alarming string of vulnerabilities in a leading blockchain voting system called Voatz. Network attacks could also reveal where a given user was voting and potentially suppress votes in the process, the paper claims.

User Control of Personal mHealth Data Using a Mobile Blockchain App: Design Science Perspective
Blockchain-based decentralized apps can do anything web or mobile apps can do, while maintaining privacy, keeping immutable records and bypassing middlemen. Under the hood, however, DApps generally share several basic characteristics that set them apart from their centralized kin. Smart contracts can also be written and executed privately, without the need to identify the parties. That said, those strengths of DApps and their smart contracts also creates a weakness: any mistake in writing the contract or exploit found by unscrupulous parties cannot be reversed.
That mean that smart contracts must — or at least should — be analyzed to guarantee they will be executed in the way intended. While Ethereum remains far and away the dominant DApp platform, it suffered substantial growing pains in , with DApps from two booming segments overwhelming it, often making transactions slow and very expensive. CoinMarketCap News. What Are DApps?
Table of Contents. Get Smart Contracts. By Leo Jakobson. The main difference is that decentralized apps — DApps — run on distributed and immutable blockchain networks rather than a centrally controlled operating system.
This makes them essentially impossible to censor. In terms of what they can do, DApps run everything from games and marketplaces to decentralized finance DeFi lending platforms.
First, DApps must be open source, meaning the code is available for anyone to see, and any updates and changes decided upon through a consensus mechanism that amounts to some form of majority vote rather than by a developer.
Second, DApps must obviously be decentralized. This means all data and records generated by the DApp are stored on an immutable , public blockchain. Third, DApps are incentivized, generating and using tokens to reward validators.
By these definitions, Bitcoin itself qualifies as a DApp, albeit one with its own built-in blockchain. That said, almost all DApps have smart contracts at their core. These are self-executing agreements with the terms between buyer and seller written into the code. Smart contracts are settled automatically when predetermined conditions are met, doing away with intermediaries that inject cost and risk into transactions. These can be relatively straightforward — trading one cryptocurrency for another or buying a piece of art on an NFT marketplace — or very complex.
While Ethereum seeks to resolve its troubles by moving from a proof-of-work consensus mechanism to proof-of-stake — better known as Ethereum 2. And it has a number of benefits when it comes to DApps, starting with Solidity , a well-established language for writing DApps for Ethereum Virtual Machine.
EVM is Turing complete, meaning it can execute any operation a regular computer can.

With the huge competition already existing in the marketplace, start-ups are struggling to make use of newer technologies to stand out in the competition. Skilled mobile app developers are now being hired by start-ups leading to the massive growth of the industry. One of the new technology being used by start-ups is the blockchain technology which it has been popular since long due to its association with cryptocurrencies like Bitcoin. Now, however, this technology is being used in the mobile apps not only for making the transactions fast but also for keeping most important user information secure. Though blockchain technology has been popular initially as a base for the stable functioning of every cryptocurrency, it is now being looked upon as a database that can be used almost any mobile app.

Metrics for assessing blockchain-based healthcare decentralized apps Abstract: Blockchain is a decentralized, trustless protocol that combines transparency, immutability, and consensus properties to enable secure, pseudo-anonymous transactions. Smart contracts are built atop a blockchain to support on-chain storage and enable Decentralized Apps DApps to interact with the blockchain programatically. Programmable blockchains have generated interest in the healthcare domain as a potential solution to resolve key challenges, such as gapped communications, inefficient clinical report delivery, and fragmented health records. This paper provides evaluation metrics to assess blockchain-based DApps in terms of their feasibility, intended capability, and compliance in the healthcare domain.
