The Nexa team extends its wishes for a productive, healthy, and successful year ahead. Looking back at December, it was a period marked by continued progress across the ecosystem. Development efforts remained active, the team expanded, and groundwork was laid for initiatives planned for the year to come. ## Crypto, Not Bitcoin: As Demonstrated by the Nexa Blockchain Andrew Stone has been involved in Bitcoin’s technical, political, and economic evolution for more than a decade. In his presentation Crypto, Not Bitcoin, he examined how Bitcoin has diverged from its original purpose, transitioning from an open, expressive peer-to-peer system into a more constrained and institutionally dominated financial asset. The presentation advanced a broader vision of cryptocurrency as a language for expressing identity, ownership, and exchange, and demonstrated how the Nexa blockchain implements this vision in practice today.

The discussion explored Bitcoin’s scalability challenges, the evolution of layer one solutions, and Nexa’s UTXO based blockchain design. Andrew reflected on discovering Bitcoin in 2012 through a Linux magazine, his early concerns regarding the one megabyte block size limit, and the role Bitcoin Unlimited played in advocating for on chain scaling, supported by early developers such as Satoshi Nakamoto, Gavin Andresen, and more.

To commemorate the milestone, B.U. hosted a public anniversary Space on X, bringing together developers, contributors, long-time community members, and newer participants. The discussion served as both a celebration and a retrospective examination of Bitcoin Unlimited’s intellectual and engineering contributions, from early scaling debates to the eventual launch of Nexa as a purpose built next generation blockchain. Over the past decade, Bitcoin Unlimited consistently emphasized the principles outlined in Satoshi Nakamoto’s original whitepaper, including peer-to-peer electronic cash, open participation, and decentralized governance.

Bitcoin mining began with CPUs, transitioned to GPUs, and later to custom ASICs as participants sought greater efficiency and performance. Each generation of hardware brought measurable gains in speed, energy efficiency, and cost reduction, shaping the competitive landscape of mining. Building on these historical lessons, research into hardware acceleration continued to inform Nexa’s long term scalability strategy.

The letter emphasized Nexa’s commitment to careful engineering, patience, and long horizon infrastructure development. Rather than focusing on short term milestones, the message reiterated that meaningful infrastructure is built over years rather than weeks or months, and expressed appreciation for community members who continue to support Nexa with this perspective in mind.

Building meaningful infrastructure takes time, and Nexa was never designed to be measured in weeks or month… ## Tailstorm Implementation: Moving from a Traditional Blockchain to a Tailstorm-Style DAG Core developers began integrating Tailstorm, a block DAG based design derived from Tailstorm research. This architectural evolution moves Nexa beyond a strictly linear blockchain toward a directed acyclic graph (DAG) of sub-blocks, while retaining a conventional chain of summary blocks. By combining these approaches, Nexa aims to benefit from advanced block propagation and mining mechanisms while maintaining compatibility with established blockchain structures.
