TL;DR
- bitFlyer, Japan’s largest Bitcoin exchange, added Ethereum trading to its bitFlyer Lightning platform
- Ethereum’s aggregate value reached approximately 83 billion JPY ($760 million) as of April 9, 2016
- Bitcoin and Ethereum together accounted for 90% of the total cryptocurrency market
- The launch coincided with R3’s unveiling of Corda, a distributed ledger for financial institutions
- Steam also began accepting Bitcoin payments in April 2016 through BitPay
Japan’s Crypto Giant Bets on Ethereum
bitFlyer’s decision to add Ethereum trading represented a significant milestone for the second-largest cryptocurrency by market capitalization. As of April 9, 2016, Ethereum’s aggregate value stood at approximately 83 billion JPY (roughly $722 million), making it a distant but growing second to Bitcoin’s 700 billion JPY valuation. The total cryptocurrency market at the time reached approximately 864 billion JPY, with Bitcoin and Ethereum together commanding a dominant 90% share of the entire industry.
The new service was initially available only to qualified customers, reflecting bitFlyer’s cautious approach to expanding its cryptocurrency offerings. The integration into bitFlyer Lightning — the exchange’s professional-grade trading platform — meant that experienced traders could now seamlessly move between Bitcoin and Ethereum markets, a capability that was still relatively rare among major exchanges in early 2016.
Ethereum’s Rising Profile in Early 2016
Ethereum was still a young platform in April 2016, having launched less than a year earlier. Yet its market capitalization had already grown to represent a meaningful alternative to Bitcoin. At a price of approximately $9.15 per ETH and with nearly 79 million ETH in circulating supply, Ethereum was beginning to attract serious attention from both retail and institutional players.
The addition of ETH trading on bitFlyer was particularly significant given Japan’s position in the global cryptocurrency ecosystem. Japan had emerged as one of the most crypto-friendly nations, with a regulatory environment that was increasingly accommodating to digital assets and a tech-savvy population eager to explore new financial technologies.
R3 Unveils Corda: Blockchain Goes to Wall Street
The same week saw another major development in the blockchain space. R3, the consortium of over 40 global banks working on distributed ledger technology for financial services, officially introduced Corda — a distributed ledger platform designed specifically for regulated financial institutions.
Corda was notably different from public blockchains like Bitcoin and Ethereum. As described by Richard Gendal Brown, R3’s Chief Technology Officer, the platform was designed from the ground up to record, manage, and synchronize financial agreements between regulated financial institutions. Key design choices included no unnecessary global sharing of data, no native cryptocurrency, and direct regulatory and supervisory observer node capabilities.
The R3 team, led by Chief Engineer James Carlyle and Lead Platform Engineer Mike Hearn, had spent six months building the prototype with contributions from consortium member banks. The platform’s emphasis on privacy and regulatory compliance represented a distinctly enterprise approach to blockchain technology — one that sought to capture the benefits of distributed ledgers without the transparency and pseudonymity that characterized public chains.
Steam Accepts Bitcoin: Gaming Meets Cryptocurrency
April 2016 also marked another milestone for Bitcoin adoption: Steam, the world’s largest digital gaming distribution platform, began accepting Bitcoin payments through the payment processor BitPay. The move opened Bitcoin to millions of gamers worldwide and represented one of the most significant mainstream merchant adoptions of the cryptocurrency to date.
At the time of the integration, Bitcoin was trading around $419 — a price level that, notably, some analysts considered “grossly overpriced” even as the cryptocurrency had been more stable than gold for the preceding 24 days. The debate over Bitcoin’s intrinsic value would continue, but Steam’s acceptance signaled a growing recognition that the cryptocurrency had practical utility as a medium of exchange.
Bitcoin Core 0.12.1 and the Road to SegWit
On the technical front, April 2016 saw the release of Bitcoin Core 0.12.1, which included foundational code for Segregated Witness (SegWit). This upgrade was a critical milestone in Bitcoin’s scaling debate — a contentious discussion that had been dividing the community for months. SegWit promised to increase Bitcoin’s effective block size limit while also fixing transaction malleability, laying the groundwork for future layer-two scaling solutions like the Lightning Network.
The scaling debate was particularly heated in mining circles, with Chinese mining pools like AntPool and F2Pool controlling significant portions of the network’s hashrate. These pools had been advocating for larger block sizes as an alternative to SegWit, creating a political fault line that would eventually lead to the Bitcoin Cash fork in 2017.
Why This Matters
The developments of early April 2016 represent a pivotal moment in cryptocurrency history. bitFlyer’s addition of Ethereum trading signaled that the market was maturing beyond Bitcoin maximalism, while R3’s Corda demonstrated that blockchain technology was being taken seriously by the traditional financial establishment. Steam’s Bitcoin acceptance showed that cryptocurrency was finding real-world use cases beyond speculation and trading. Together, these events painted a picture of an ecosystem that was rapidly expanding in multiple directions — more assets, more institutional interest, and more mainstream adoption — while simultaneously wrestling with fundamental questions about scalability, governance, and the proper role of decentralized technology in a regulated financial world.
