IBM Food Trust, Walmart’s blockchain-based food traceability system, launched in 2018 with a demonstration that became one of the most frequently cited proof points for enterprise blockchain. A mango that had previously taken six days to trace from store shelf to farm of origin could be traced in 2.2 seconds using the blockchain system. The demonstration was real. The subsequent adoption curve was more complicated.

Supply chain traceability is the enterprise blockchain use case that generated the most serious investment and the most careful subsequent analysis. The results are instructive for anyone evaluating where distributed ledger technology creates genuine value and where it serves primarily as marketing infrastructure for complexity that simpler systems could handle.

The collapse of FTX in November 2022 was the most consequential single event in crypto exchange history. It destroyed the second-largest exchange by volume, took several billion dollars of customer funds with it, and produced a regulatory response that has fundamentally altered the competitive dynamics of the exchange industry. Three years later, the consolidation that FTX’s collapse accelerated is still in its early stages.

The exchange industry’s structure before FTX was already oligopolistic. Binance, FTX, Coinbase, and a small number of other platforms accounted for the overwhelming majority of spot and derivatives trading volume. What appeared to be a competitive market was, on inspection, a highly concentrated one in which the second-place player’s existence owed more to regulatory arbitrage and aggressive fee subsidization than to sustainable competitive differentiation.

The mathematics underlying zero-knowledge proofs has been understood since the 1980s. The computational cost of generating and verifying them was, for most of that period, prohibitive for practical applications at scale. What changed over the past several years was not the theory but the engineering: proof generation times dropped by orders of magnitude, hardware acceleration made ZK computation economically viable, and a generation of cryptographers trained in both theory and systems engineering turned their attention to making the technology work in production.

The Markets in Crypto-Assets regulation came into full effect in the European Union at the end of 2024, completing a legislative process that began in 2020. MiCA is, by any measure, the most comprehensive crypto regulatory framework enacted by any major jurisdiction. It is also, by the assessment of most practitioners who have spent the past year implementing compliance against it, a framework with genuine strengths, notable gaps, and implementation details that will be litigated for years.

The history of enterprise blockchain in trade finance is a useful corrective to the cycles of enthusiasm and dismissal that characterize coverage of distributed ledger technology. Neither the enthusiasts who projected that blockchain would eliminate trade finance friction within five years nor the skeptics who declared enterprise blockchain categorically pointless have been vindicated. What happened was messier, slower, and more instructive than either camp anticipated.

The high-profile failures are well documented. IBM and Maersk’s TradeLens platform — the most ambitious attempt to put global shipping documentation on a blockchain — shut down in 2022 after failing to achieve the network effects that made it valuable. We.Trade, a European trade finance platform backed by major banks, went into administration in 2022 as well. Marco Polo, another bank-backed network, faced similar difficulties.

Every major blockchain application eventually collides with an identity problem. DeFi lending protocols that want to offer uncollateralized loans need to assess creditworthiness without holding custody of user data. DAO governance systems that want to prevent sybil attacks — one person controlling many wallets to accumulate disproportionate voting power — need to verify personhood without requiring real names. Regulatory compliance frameworks that require KYC create friction that is incompatible with the permissionless design of public blockchains.

The NFT market’s collapse from its 2021 peak was faster and more complete than almost any comparable speculative episode in recent memory. Trading volumes that had reached billions of dollars monthly fell by more than ninety-five percent. Projects that had sold for hundreds of thousands of dollars became effectively worthless. The journalists who had written breathless profiles of digital artists selling JPEGs for millions wrote equally breathless obituaries two years later. Both sets of articles were, in different ways, missing the point.

MicroStrategy’s decision to hold Bitcoin as its primary treasury reserve asset was, when Michael Saylor announced it in 2020, widely characterized as either visionary or reckless depending on the observer’s priors. Five years later, the company has rebranded as Strategy, holds over half a million Bitcoin, and has generated returns on its Bitcoin position that dwarf what any treasury management program operating in conventional instruments could have produced. The characterization as reckless has mostly been retired.

Cryptocurrency legislation in the United States has been promised, debated, drafted, amended, shelved, redrafted, and promised again so many times that the industry had largely stopped treating legislative progress as meaningful until a bill reached the floor. The Digital Asset Market Clarity Act’s passage out of committee with bipartisan support is a different moment. It does not guarantee enactment, but it represents the closest the United States has come to a comprehensive crypto regulatory framework since the asset class became economically significant.

For most of the past decade, crypto companies operating in the United States have been navigating regulatory uncertainty using a combination of legal creativity, jurisdictional arbitrage, and optimism that clarity would eventually arrive. The SEC’s enforcement-first approach — pursuing actions against specific actors rather than publishing comprehensive guidance — left the industry in the position of learning the rules from the outcomes of cases it was not party to.

The taxonomic guidance that the SEC published in early 2026 does not resolve every question. It resolves enough of them to allow compliance functions to make decisions they have been deferring for years.
