Over the holiday season, CoinDesk published a wide range of feature articles from experts and stakeholders in and outside of the bitcoin and blockchain industry.

Billed as our 2015 Review, the series encouraged guest writers – including experts on law and finance, academics, entrepreneurs and even readers – to discuss the year past and the year ahead.

Our contributors didn't always agree, but they did come up with a number of intriguing predictions, each influenced by their unique positions and experiences in the field.

In this article, we've pared down that information to define seven key trends that could shape the story of the bitcoin and blockchain industry in the coming months:

2016 is likely to see blockchain technology move beyond discussion and into the financial market, professional services firms say.

In exclusive pieces by PwC and Deloitte, both of the firms, which are actively working with financial partners to develop proofs-of-concept (POCs), believe their work will see a wider audience this year.

In a piece entitled Blockchain Will Become a Reality in 2016, Deloitte's Eric Piscini, Simon Lapscher and Andrew Garfrerick, wrote:

Many of the standard financial services use cases (such as international payments, trade settlement, compliance, etc) will slowly be turned into fully fledged products in the next 12 months, they predicted.

"Whether it is through internal blockchain labs, direct partnership with blockchain tech companies or through collaborations with platforms such as Deloitte’s own Rubix, many of the main financial institutions are now past the thinking and ‘testing-the-waters’ stage, and into the product development stage," wrote Piscini, Lapscher and Garfrerick.

However, some still believe there’s a lot of work still to do before blockchains come into common usage.

Preston Byrne, co-founder and COO of Eris Industries, wrote in his piece that we’re two budget cycles away from the first production systems in finance, and that we’re probably 10 years away from mainstream use.

This past year has seen an enthusiastic spike in activity as major financial institutions have moved to experiment with bitcoin and develop blockchain applications.

However, it remains to be seen how these use cases will be impacted by regulation, which to date has largely focused bitcoin and other cryptocurrencies.

In CoinDesk's 4 Trends That Will Shape Bitcoin Regulation in 2016, Jason Weinstein and Alan Cohn, both US attorneys and counsels to the Blockchain Alliance, wrote:

Indeed, the US Commodity Futures Trading Commission (CFTC) is to discuss the application of blockchain technology in derivatives markets during a meeting of its Technology Advisory Committee later this month.

Weinstein and Cohn predicted that maintaining positive engagement will help government agencies develop a better understanding of the benefits of bitcoin and the blockchain.

This will "help foster an approach to enforcement and regulation that supports innovation and growth, so this transformative technology can reach new heights in 2016 – and beyond", they wrote.

Michael Jackson, former COO of Skype and board member at bitcoin wallet provider Blockchain, expressed confidence in bitcoin and its potential to grow to mass adoption in his article Bitcoin's Big Challenge in 2016: Reaching 100 Million Users.

Bitcoin can grow to rival the usage figures boasted by globally popular apps such as Snapchat, Facebook and Twitter, he suggested.

"Despite our lack of progress, we have something precious. Anecdotally, I can’t think of a single other back-end system that has been online for seven years without a glitch, running 24 hours a day, seven days a week, 365 days a year. The bitcoin blockchain has proven its resilience," he wrote.

However, he identified a significant challenge facing the digital currency and warned that bitcoin firms must "successfully obfuscate the complexity of bitcoin and bring frictionless value transfer to the next 100 million daily users".

2015 was the year that many banks and financial institutions report they began to see the potential of blockchains and distributed ledgers, and these groups flocked to set up their own research projects or joined consortia to investigate how their businesses might be impacted.

However, the ability of blockchains to cryptographically verify and record transactions, is starting to find appeal across a number of other industries.

Most notably, perhaps, insurance firms are starting to investigate blockchain technology, with Accenture, Lloyd's and Allianz France all recently stating an interest.

Michael Mainelli, executive chairman of Z/Yen Group and principal advisor to Long Finance,tackled this subject in a piece entitled Why Insurers Caught the Blockchain Bug in 2015.

Noting that these groups have interests that may lead them to consider decentralized technologies, Mainelli said:

He added that Z/Yen, a commercial think-tank, has already built insurance application prototypes for clients in areas such as motor and small business.

The piece was later echoed by Abizer Rangwala, a managing director for Accenture, who would write that he believes the insurance industry will move to embrace the technology within the "next few years".

Provenance – or the tracking of ownership – was also cited as a use case that would see further growth this year.

The digital tokens that a blockchain could, proponents say, can also be used as digitized representations of the documents that accompany financial transactions or goods on a supply line.

There are numerous use cases within finance, where many processes involve the processing of shared documents between various parties. Beyond finance, a blockchain can provide a full audit trail of a piece of data's origin in both time and place. In this way, a blockchain can act as a provenance protocol for data across disparate semi-trusting organizations.

In a recent real-world example, there is even a startup calling itself Provenance that is aiming to use blockchains to build more transparency into supply chains.

"Assuming that bitcoin remains the most popular token to run the blockchain and transaction volumes continue to rise, the next few years should be spectacular for the price of bitcoin," said Richelle Ross, an independent cryptocurrency consultant.

In her piece for CoinDesk, Why I'm Predicting a $650 Bitcoin in 2016, Ross suggested that 2016 will be more "action-packed" than last year, anticipating positive price moves associated with the digital currency's maturing infrastructure and the block halving due this summer, where the amount of bitcoins awarded to miners roughly every 10 minutes will be cut in half.

Warning that there are "too many unknown factors when predicting price to know with any certainty", she concluded that the price will finish the year around the $650 mark.

The topic of the coming rewards halving was also brought up in "2016 Could Be Bitcoin's Best Year Yet" by Adamant Research's Tuur Demester.

There, Demester said he expects the event to have a "positive" impact on bitcoin, though he stopped short of any direct price predictions.

With such a recent and innovative technology to come to grips with, many established institutions, startups and regulatory agencies have found partnering to be the most promising way forward.

Deloitte's experts suggested this trend will likely increase this year, as companies try to leverage the capabilities of partners to help drive critical research and development of new blockchain use cases.

Additionally, they wrote: "Certain firms also look to provide 'network leadership' within the space – that is, to help connect the dots between different players within the ecosystem who may benefit from large forums in which to market themselves and share knowledge."

New York-based R3 already leads a group of more than 40 financial institutions, aiming to drive innovation and standards in financial services. Other working organizations, including one focused on post-trade settlement, have also emerged in recent months.

Still, not everyone agrees.

Nomura Research Institute

, for example, has suggested the slow advancement of such efforts could make private POCs more attractive.

Venture funds are increasingly noticing enterprise interest in blockchain, and despite big early bets that bitcoin may prove to be a disruptive in the space, seem more and more keen to back startups aiding banks in their research.

As evidenced by the trends above, VCs see opportunities for startups in partnering with institutions or providing incidental services around the periphery of this new tech, including blockchain APIs and ID verification services.

This is likely to draw in investors who see the potential for blockchains and want to get in early.

Virtual Capital Ventures' William Mougayar forecast that VC investments in blockchain-related startups will exceed $2.5bn all-time in 2016 – dwarfing even the most optimistic of estimates for bitcoin startups in 2015. This doesn't include what the banks will spend from their operating budgets, either.

Already this year we've seen signs existing bitcoin startups are changing gears as well.

Gem, which pivoted focus from bitcoin APIs to more general blockchain versions of this product, has closed a $7.1m Series A funding round led by Pelion Venture Partners.

There is a caveat, however, startups shouldn't assume a windfall is likely just because they deal with the blockchain.

Digital Asset Holdings, the startup led by respected ex-JPMorgan exec Blythe Masters, is apparently having issues closing its inaugural investment round.
