Public tests of blockchain-based mobile voting are growing.

Even as there’s been an uptick in pilot projects, security experts warn that blockchain-based mobile voting technology is innately insecure and potentially a danger to democracy through “wholesale fraud” or “manipulation tactics.”

The topic of election security has been in the spotlight recently after Congress held classified briefings on U.S. cyber infrastructure to identify and defend against threats to the election system, especially after Russian interference was uncovered in the 2016 Presidential election.

Hoping to raise awareness about blockchain vulnerabilities, cybersecurity firm Kudelski Security next week plans to launch the industry’s first “purposefully vulnerable” blockchain – and will demo it at next month’s Black Hat conference.

Kudelski Security’s FumbleChain project is aimed at highlighting vulnerabilities in blockchain ecosystems, according to Nathan Hamiel, head of cybersecurity research at Kudelski.

The flawed blockchain ledger is written in Python 3.0, making it easy for anyone to read and modify its source code, and it’s modular – allowing users to hack and add new challenges to promote continuous learning.

While blockchain holds tremendous potential for creating new financial, supply chain and digital identity systems, it’s often erroneously seen as a panacea for business problems.

The myriad of pilots and proofs of concept by large corporations and government agencies are showing real promise, but those projects don’t always lead to obvious business cases that justify doing something differently. Sometimes a tried and true technology like a relational database can perform the task much more efficiently than a distributed ledger based on peer-to-peer technology that will require complex governance and rules.

AT&T will allow customers to pay their mobile bills using Bitcoin, adding its name to a short list of major businesses and government agencies that allow the blockchain-based cryptocurrency to be used as a form of payment.

While not directly accepting cryptocurrency, AT&T is the first major U.S. mobile carrier to let customers pay in Bitcoin through a third-party service provider.

Customers using its online bill pay service or the myAT&T app will be able to choose BitPay, a cryptocurrency payment processor for payments. The customer pays in Bitcoin and BitPay verifies the funds and accepts the Bitcoin on behalf of the business.

In two separate announcements last week, Google and Linux’s Hyperledger project launched tools aimed at enabling secure identity management for enterprises via mobile and other devices.

Google unveiled five upgrades to its BeyondCorp cloud enterprise security service that enables identity and access management for employees, corporate partners, and customers.

IT leaders who’ve taken the plunge into blockchain are mainly deploying it in proofs-of-concept tests to address the same problems a conventional database could handle, according to research firm Gartner.

Sharding: What it is and why many blockchain protocols rely on it

As blockchains are being rolled out in an increasing number of pilot programs for everything from cross-border financial transactions to supply chain management, one persistent issue remains: a lack of scalability.

As more computers join the peer-to-peer network, the efficiency of the whole system typically degrades.

Scalability has already been identified as an issue with cryptocurrencies such as bitcoin and Ethereum’s Ether. If a distributed ledger is to achieve adoption by financial technology (FinTech) companies and compete with payment networks hundreds of times faster, it must find a way to boost scalability and throughput and address latency problems.
