2016 Blockchain Year in Review for Casual Observers

2016 Blockchain Year in Review for Casual Observers

2016 is over and there are still no mainstream use cases for Bitcoin or any other blockchain. Given how much media hype there has been since the fall of two thousand thirteen when the U.S. Congress and the Chairmain of the Federal Reserve very first spoke publicly about Bitcoin, casual observers may think the space is dead.

Bitcoin adoption has continued to grow this year tho’ and several other blockchains have emerged. If you look at the data, it is clear that blockchains are displaying promising growth and will have major implications for the ownership rights, security and power of people around the world.

What is a blockchain?

The term “blockchain technology” gets used fairly broadly, so to understand the state of blockchains in 2016, it is significant to very first understand what the term means.

Simply put, a blockchain is a collective database where the access to and integrity of the data is not managed by any one central party. A database that no one controls and anyone can use has far reaching implications for everyone who has data stored in a traditional database today (think assets like money, equity and physical property and identities like private IDs, unique IDs of physical objects, digital identities, etc.). Large companies and governments presently control all of this data, which is good for the companies and governments but bad for the users of these services from a security and privacy perspective. Blockchains fundamentally put control of security and privacy (and power as a result) in the arms of the people.

Bitcoin aka “digital gold” continued to thrust forward in 2016

The Bitcoin blockchain is the most significant blockchain today. Nakamoto Consensus was the big technological breakthrough that commenced the blockchain revolution and the Bitcoin blockchain’s longevity, security and user base is presently unrivaled. The token required to use the Bitcoin blockchain is bitcoin (BTC).

Today the total market value of bitcoin is $15B (up 114% this year as of 12/27/16) and over $180M is transacted on the network daily. The transaction volume, trading volume and number of transactions on the Bitcoin network continued to increase this year and the volatility continued to decrease.

There were no killer use cases that directly enhanced mainstream bitcoin adoption in 2016, and the primary use case for bitcoin remains the store of value/speculative asset use case. Bitcoin has many of the same properties that gold has as a store of value (scarcity, durability, divisibility); bitcoin can also be sent anywhere instantly and for free, making it an attractive alternative to gold for many.

There were several macroeconomic events this year that led more people to gravitate to bitcoin as a “store of value” (see the Brexit, the Chinese Yuan depreciating in value and the Venezuelan bolivar collapsing). There’s no strong reason to believe these types of macro events caused by centralized governance structures won’t proceed.

Here’s the most significant Bitcoin data from 2016:

Transactions on the Bitcoin network are at an all-time high, up 50% Y/Y

30 day BTC-USD volatility is at an all-time low, down 75% since 2010

Bitcoin price is up 114% in 2016

Bitcoin headwinds in 2016

While Bitcoin made progress this year, there were also some challenges. Given the lofty expectations private investors had in 2013, ’14 and ’15, when over $1.4B of venture capital was invested in the space, some are disappointed that things haven’t moved quicker at the protocol level and use cases haven’t emerged at the application level. Many would cite the two primary headwinds as the unresolved blocksize debate and the slowing down of innovation on top of the Bitcoin protocol.

Bitcoin applications that launched this year, such as the peer-to-peer marketplace OpenBazaar and the web browser with micropayments built-in Courageous, have shown promise but have not crossed the chasm to reach mainstream users yet. Additionally, scalability solutions that increase the transactions per 2nd limit (over seven transactions/2nd presently slows down the network), such as the lightning network, have shown promise but are not live yet.

These headwinds will be significant to pay attention to in 2017.

Fresh blockchains emerged in 2016

The number of open-source protocols that have been widely used in the past thirty years can be counted on one mitt (HTTP for the web, SMTP for email, BTC for money). Most of the innovation in software has occurred at the application layer, led by companies that extract significant profits and don’t always put the security and privacy of users very first (e.g. Google, Facebook and Amazon).

Bitcoin has inspired developers around the world to launch blockchain-based protocols that empower users in fresh ways. A number of fresh blockchain-based protocols have gained significant traction this year. In our estimation, the following blockchain-based protocols presently have the most potential to become the future backbone infrastructure for the Internet:

Ethereum is a developer-friendly blockchain that makes it effortless for developers to build decentralized applications. Ethereum is the 2nd most well-known blockchain, with a total market value of $630M (up 671% in 2016) and a very sturdy developer ecosystem that is attracting fresh developers to the blockchain space. Albeit no mainstream use cases have emerged yet (the Ethereum blockchain is just 1.Five years old), there has already been over $160M worth of token sales transacted using Ethereum wise contracts. Crowd sales have been the major use case for Ethereum thus far.

Zcash is a privacy-focused peer-to-peer payment protocol that permits users to secure and send funds anonymously. Bitcoin has a semitransparent ledger that exposes the address, amount and time of every transaction. Zcash uses some breakthroughs in cryptography to make transactions private. Launched on October 29th, Zcash is just a few months old and presently has a total market value of $14M.

Steem is a blockchain-based media platform that makes it effortless for content creators to earn tokens directly from the Steem blockchain. Steemit, the largest social network built on the Steem blockchain, is the very first and largest service built on top of Steem but not the only. Steem has a sturdy developer ecosystem and the total market value of Steem is $36M.

It is unclear whether the acceleration of these fresh blockchain-based protocols will have staying power — the reality is that the vast majority of the value created so far has been speculative value. But it is clear that blockchains beyond Bitcoin have momentum heading into 2017.

See below for the top twelve digital assets from a price appreciation perspective (criteria for inclusion: trading for >12 months, total market value >$3M and average daily trading volume >$10K).

Blockchain crowd funding emerged in 2016

Ethereum makes it very plain for a developer to set up an address, receive funds at that address and issue tokens directly to the address of the sender. Crowd funding via a token issuance enabled by Ethereum has become a fresh way for any developer with an idea to get funding for a project, align incentives and acquire sultry early users. Despite the regulatory uncertainty associated with this model, there has been a lot of early activity.

There were several other crowd funding projects with varying degrees of quality and success in two thousand sixteen — from the DAO, an $130M decentralized venture fund that failed due to a security flaw, to Golem, a promising project that raised over $8M. It will be interesting to see if this trend resumes in two thousand seventeen and beyond.

Private blockchain projects continued in 2016

There are now over twenty five consortiums of private blockchain projects. R3 is the most well-known, with participation from over seventy financial institutions. Unlike public blockchains, these private blockchain projects lack public data, so it’s unlikely to evaluate the traction of these projects objectively. There weren’t any financial institutions using private blockchains in production in two thousand sixteen however — we’ll see if this switches in 2017.

Summary and extra resources

If you’re reading this as a casual observer, you still may not have a clear sense for why blockchains are significant to you. The reality is that to most people, they’re not yet significant and they won’t be until you’re actually using them in your every day life.

In 2016, speculation and investment in digital assets (primarily Bitcoin) and crowd sales (primarily via Ethereum) were the main use cases for blockchains. Beyond these, there are a diversity of ways that blockchains are beginning to empower people by providing them control of their own digital identity, physical property and money. The continuing developer momentum is likely to bring more of this innovation to light in the coming years, however there’s a lot of work to be done!
