The Blockchain Industry's Clever Pivot, From the Unbanked to the Bots
The pitch arrives on schedule. Every few years, the blockchain industry identifies the next great technological transformation, then quietly inserts itself into the centre of the diagram. At Proof of Talk 2026 in São Paulo, Brazil, the chosen wave was artificial intelligence. Tom Lee of Fundstrat Global Advisers told attendees that "robots are going to dominate internet traffic, and that's where blockchain is more effective than traditional rails." His tone was unhurried, confident — the cadence of someone delivering a well-rehearsed keynote to a sympathetic room.
That confidence deserves scrutiny. The claim that blockchain will outperform "traditional rails" in an AI-dominated environment rests on a specific hypothesis: that automated systems will need verifiable, tamper-resistant transaction records at machine-to-machine scale, and that distributed ledger technology is best placed to provide them. It is not an unreasonable proposition. But it is also not a new one. The blockchain industry has been promising infrastructure-scale transformation since at least 2017, when the last cycle of similarly confident forecasts failed to materialise at the projected pace.
The Narrative Recycling Problem
When the original decentralisation thesis stalled — Bitcoin never replaced fiat, Ethereum never displaced the existing financial system — the industry pivoted to "banking the unbanked." When that claim proved difficult to substantiate at scale, the pivot moved again. DeFi was next, then NFTs, and now, with the mainstreaming of large language models and autonomous agents, the pitch has shifted to blockchain as the trust layer for an automated internet. Adam Back, the Blockstream co-founder and Hashcash inventor, offered a version of this framing in São Paulo: "You can think of Bitcoin as the internet of finance," he said at the conference.
The analogy is revealing precisely because it dodges the harder question. The original internet of finance — a decentralised, open, permissionless payments network — does not, in practice, resemble the concentrated, fee-laden, institutional ecosystem that Bitcoin has become. The metaphor performs rhetorical work without doing analytical work. It reframes a contested outcome as an accomplished fact.
What makes the São Paulo panels distinctive is not the technology being promoted but the audience being addressed. These are not retail investors. They are an industry audience: conference attendees, protocol developers, financial infrastructure professionals. The framing that works in that room — bold architectural claims about machine-readable ledgers and AI-internet infrastructure — is calibrated for the converted. The evidence that follows them outside the conference centre is considerably thinner.
The Interoperability Gloss
Ken Moore, Mastercard's chief innovation officer, offered the most concrete contribution to the São Paulo discussions. "The future is interoperability between stablecoins, tokenised bank deposits, CBDCs, and fiat," he said at Proof of Talk 2026, according to Cointelegraph's reporting.
This framing is interesting precisely because it is not a blockchain thesis at all. It is a network effects argument: the value is in the connections between systems, not in any single one of them. Moore is describing the architecture of modern payment rails, of which blockchain is one component — and not necessarily the most important one.
The interoperability argument also has a convenient political valence. It deflects the harder questions — which blockchain? which consensus mechanism? whose rules? — by suggesting that the answer is, ultimately, all of them. Everyone gets to stay in the diagram. Nobody has to pick a winner. But the gloss obscures an underlying institutional reality: the payment systems doing the actual interoperability work are the ones with the existing infrastructure, the regulatory relationships, and the consumer trust. Mastercard's blockchain strategy is not to build a competing system. It is to absorb the technical components that are useful and leave the rest.
Who Controls the Rails
The deeper issue is structural. The blockchain industry's most durable claim — that decentralised ledgers will displace centralised intermediaries — has run into a persistent empirical problem. The intermediaries have not been displaced. They have, instead, built on top of the ledger technology. When JPMorgan or Mastercard or a major sovereign wealth fund tokenises assets on a blockchain, they are not ceding control of the rails. They are extending their existing rails into a new technical format.
This is not a conspiracy. It is the normal behaviour of incumbent institutions in the face of a new technology: absorb the efficiency gains, retain the relationship with the customer, preserve the fee structure. The blockchain becomes infrastructure, absorbed into the existing payment stack rather than displacing it.
The three speakers at Proof of Talk 2026 have professional interests in their respective corners of this ecosystem. Lee runs an advisory firm. Back co-founded a blockchain infrastructure company. Moore represents a payment network with a multi-decade investment in maintaining the dollar-denominated transaction system. None of this disqualifies their observations. But the convergence of their talking points — blockchain as the connective tissue of an AI internet, Bitcoin as the internet of finance, interoperability as the design principle — reflects something closer to industry positioning than independent analysis.
The evidence base for these claims is thin in the specific, concrete sense that matters. Not the macroeconomic logic — that digital money will become more automated and more interoperable is almost certainly true — but the specific attribution to blockchain as the essential infrastructure layer. The same automation and interoperability could be delivered through existing payment rails, through centralised databases operated by regulated institutions, or through a combination of both. Blockchain solves a specific trust problem — the need for a neutral, permissionless record-keeping system in the absence of a trusted central party. Whether that problem is actually the limiting constraint in the AI-internet infrastructure of 2030 is a different question, and one the São Paulo panels did not seriously engage.
The Horizon Problem
Blockchain's trajectory in financial infrastructure is real but bounded. Stablecoin adoption is growing. Tokenised bank deposits are being piloted. Institutional participation in on-chain markets is increasing. These are genuine developments, and they deserve serious analysis.
But the specific framing on display in São Paulo — that blockchain's moment arrives when AI agents start transacting at machine speed — is a positioning play dressed as a forecast. The industry is pre-empting the AI narrative by inserting itself into it, in the same way it previously inserted itself into the unbanked narrative, the DeFi narrative, and the NFT narrative. Each cycle produces a new version of the same structural argument: the transformation is coming, the technology is ready, and the only question is when mainstream adoption catches up to the obvious truth.
The obvious truth, as usual, is more complicated. The financial infrastructure of 2035 will almost certainly include more on-chain activity than 2025. But whether that activity represents blockchain's ascendancy as a foundational internet technology, or merely its absorption as a specialised component within a broader digital payments ecosystem, is the question the São Paulo panels were careful not to answer.
The next two years will provide a partial answer. If the interoperability narrative collapses under the weight of regulatory fragmentation and technical complexity, the industry will find another wave to ride. The pitch, after all, is the product.
