With motor vehicles becoming an ever increasing luxury around the world, pollution levels are increasing but the Blockchain could help to reduce the transportation industry’s contribution to global warming that promises a cleaner and energy efficient future.

In an article written in December by Carsten Stöcker, Senior Manager in the Machine Economy Innovation Lighthouse Lead at German energy firm, Innogy SE and Thomas Birr, Senior Vice-President of Innovation & Business Transformation at Innogy SE, the future of transport will change through 'Blockchain-enabled secure peer-to-peer (P2P) transactions that eliminate or minimize the need for centralized authorities such as banks or ride-sharing services such as Uber or Lyft.'

Blockchain and energy transactions

Through the Blockchain, trip charges will be deducted from the passenger's Blockchain-enabled digital wallets or charged to their credit card, with payment going straight to the vehicle owner.

As noted by Stöcker and Birr, Blockchain-enabled mobility transactions mean that consumers and providers can take part in the transportation system, setting the terms, conditions and pricing they choose.

"Automotive OEMs want to collaborate with us in order to participate in building a Special Purpose Decentral Platform for Mobility Transactions,” said Stöcker, speaking to Cointelegraph. "We are also now engaging with many owners of EV charging assets around the world in order to bring charging poles to one Blockchain platform."

Yet, while the Blockchain can have a significant impact on how energy transactions are conducted, there are issues with it, such as scalability, transaction costs and offline transactions, that limit its effectiveness.

The IOTA Tangle is attempting to fix this by addressing many of the shortcomings with today's Blockchain technology by delivering secure, practical and scalable applications.

Transferring value without any fees

The IOTA is a digital currency with the goal of establishing itself as fuel for efficient machine-to-machine and Internet of Things (IoT) transactions. Instead of using a regular Blockchain, the IOTA uses its IOTA Tangle, which validates transactions in a Directed Acyclic Graph structure (DAG). This is a revolutionary new blockless distributed ledger, that is scalable, lightweight and makes it possible to transfer value without any fees.

Stöcker, who is also an IOTA Foundation member, which was founded by David Sønstebø, said that instead of achieving consensus through an expensive mechanism, which can lead to centralization, those within the IOTA network are active in the validation of transactions and consensus.

"When a device makes a transaction and broadcasts the transaction to the network, by protocol or 'by default' it has to validate two previous transactions," he said. "So, it's a real peer-to-peer network by machines for machines."

He adds that this new concept has immediate advantages: decentralization, scalability and no transaction fees.

With all IOTA tokens pre-mined, no mining is required. Not only that, but given the fact that 2779530283277761 IOTA were created, this enables transactions with little value attached to them. For instance micro-transactions, which can be beneficial within the energy industry.

Deploying the IOTA in the real world

Of course, in order to deploy the IOTA in the real world, adoption needs to be achieved in a development friendly ecosystem, which is being undertaken in its IOTA Development Roadmap.

With the IOTA Tangle designed less rigorously, it means transactions can be made in an offline environment, which copies the IoT, where devices use different networking protocols such as Lemonbeat, Bluetooth LE, LPWAN, or ZigBee.

"As such, IOTA is the first permissionless distributed ledger that achieves scalability, making Machine-to-Machine payments for the IoT possible," said Stöcker.
