"[Blockchain] spells the death of the invoice," proclaims Lee Pruitt, co-founder and CEO of spend-control-as-a-service provider InstaSupply.
"There's a huge amount of inefficiency today in business-to-business transactions," he continues. "There are a lot of steps involved when businesses place orders with suppliers and how they match them with the supplier's invoices in order to be able to pay them.
"When the accounts payable department goes through an invoice, someone has to check they received all the items being invoiced for. And is it the right price? Did the goods arrive on time? When is the supplier asking for payment? Are the payment terms correct? Is it even the right supplier?"
If there's the slightest query, the invoice is pushed to another department to get reviewed again at length by another human. Business-to-business is one of the sectors in which making and settling a transaction can involve a massive amount of manual work. In some cases, suppliers are forced to wait up to 90 days to get paid.
"Blockchain eliminates all of that," says Pruitt, "because you have a digital form of trust and verification that takes out a lot of these transactions being handled today manually."
InstaSupply is not alone in making use of blockchain in this fashion: the likes of Barclays, Maersk and Microsoft are among the very large enterprises leading the charge.
Maersk is not the only shipping company throwing its weight behind blockchain networks. Marine Transport International has developed a marine supply network using blockchain to connect stakeholders, comprising ports, shipping lines, land-based haulers, freight forwarders and other interested parties.
Marine Transport's CEO, Jody Cleworth, recounts how it came about: "Around July of 2016, there was a regulatory change in the shipping industry. This enabled us to create connectivity inside the land-side supply chain – that's before the container gets to the terminal: the truck, the load point, the shipper, the physical asset-on-asset loading of those goods inside the container.
"We realised that we could create an application which would create an ecosystem amongst these different actors to accelerate data along the land-side supply chain to meet this change. We could communicate the specifics of that container to the terminal before it was allowed into the terminal or allowed on board the ship."
Having considered and quickly dismissed the bitcoin blockchain, the company came across tech specialists Agility Sciences which was offering an enterprise-grade blockchain-as-a-service that anyone can connect to. Marine Technology discovered it could connect both legacy systems and new age EDI (electronic data interchange) protocols alike into the network, creating what Cleworth calls "a democratised connectivity".
"Now as containers are loading, data comes into the network, we process it with smart contracts, each a billable event. Then we update the applications so that users such as ourselves get notified with the various events that are going on in the container, and we push that data outside the network to the ports and the shipping lines before the truck driver has even changed into second gear to get out of that load point."
The barrier to entry to the network is low since participants themselves power it and provide its storage, whether that be via Amazon Web Services, Google, IBM Bluemix, or even their own office server. Marine Transport then earns specific fees automatically when milestones are reached in the smart contracts.
Using blockchain to level the field was also the key driver behind a distributed energy trading system rolled out in Australia earlier this year by Power Ledger.
"I was looking at the proliferation of photovoltaic (PV) solar panels which many people have installed onto their rooftops over here," recalls Power Ledger MD and co-founder David Martin.
"The problem is that there's no way of guaranteeing that you will get the benefit of the investment you make in rooftop PV. I might be working from 7am 'til 7pm, so the sun's gone down by the time I get home from work but my next door neighbour works from home, so he's getting all the benefit of that free electricity off the roof."
This scenario is a serious disincentive to install rooftop PV panels on blocks of flats, which account for 35 per cent of the housing stock in Australia. A big chunk of the population is therefore excluded from the distributed energy economy.
"What we needed was a technology platform able to demonstrate where energy was coming from at a distribution level and reward the person whose generation was being sold," says Martin. "Blockchain provided us with the ability to do that: it allows us to identify the provenance of every kilowatt hour that is generated on-site or at a consumer's premise and through a transactive platform and trading algorithm that energy is allocated to a particular consumer."
The immutable qualities of blockchain also ensure any trading arrangement can be trusted according to terms, conditions and a financial agreement tied into it.
One property making use of this system right now is a 14-unit development in Fremantle, Australia, designed for people on low-income support. The owners, a housing association, already owned the PV and battery system, and wanted to provide the cheapest electricity to their tenants in a fair manner.
The Power Ledger system sits behind the master meter of the property, identifying the consumption of energy per flat, where that energy came from and how it is priced; if one tenant uses more energy than his neighbour, he will exhaust his own discounted allocation from the rooftop PV without taking anyone else's automatically switching to energy from the network and paying the full retail price for it.
Martin feels that blockchain's boost to the growing distributed energy economy will ultimately force the major energy companies to adapt their own approach to the market.
Markus Veith, partner at Grant Thornton US shares this view of blockchain as a driver for cultural change. He uses the analogy of the appearance of smartphones: they didn't make us work faster so much as change the way we do things.
The real-world example he gives is cross-border peer-to-peer payments technology company, Circle, a rising star with whom he has been working over the last three years. Using Circle's smartphone app, you can transfer money between users across borders free of charge and instantaneously.
Veith outlines a scenario: "Let's say you're a student originally from Brazil studying in the US and you ask your parents to send you money, say $500. Your parents in Sao Paolo then go in the app and send the equivalent of $500 in the Brazilian currency Real translated into dollars, and it arrives in a split second in your account. And it's free."
Blockchain acts as a trusted recording system, validating the transfer of funds without further intermediaries and automating the settlement between accounts. Once Circle customers have established their identities on its blockchain, trust and validation are a given.
The blockchain platform reduces the risk of collusion, fraud and cyber-crime in financial services. "It's much more difficult to hack into a blockchain ledger than a traditional ledger in which you have one server," observes Veith. "With a blockchain you have multiple servers and every server validates the blockchain. If someone tries to hack a server or fake a transaction, all the others will kick it out."
The potential for blockchain based business solutions is now out there, it's just about utilising it.
