Korea Blockchain Week 2026, held September 29 through October 1 at Walkerhill Hotels & Resorts in Seoul, placed a pointed question at the center of its agenda: whether blockchains designed for human-to-human payments can support an economy run by autonomous AI agents. FactBlock organized the event, with the exchange Upbit as presenting partner.

The most forceful case came from Michael Heinrich, CEO of 0G Labs, who delivered a keynote titled "The Trillion-Dollar Agentic Economy" on September 30. His argument was that most Layer 1 blockchains — the base networks on which everything else is built — are optimized for financial transactions between people. AI agents operating autonomously, he contended, require infrastructure that payment-focused chains do not natively provide.

The gap, as speakers framed it, spans four areas. First, machine-native identity: a way to establish which agent is which and who stands behind it. Second, verifiable computing: proof that an agent actually executed the computation it claims to have run. Third, data handling at scale, meaning storage and throughput well beyond typical on-chain systems. Fourth, programmatic settlement, in which machines pay machines constantly, automatically and at high volume.

The proposed fixes

The discussions in Seoul converged on a bundle of integrated tools rather than a single upgrade. The list included Agentic ID standards, verifiable computing through Trusted Execution Environments, high-throughput decentralized storage and newer protocols such as x402.

Trusted Execution Environments, or TEEs, are secure zones inside a processor. Code running there is isolated from the rest of the system, which lets outsiders confirm that output came from the intended program without tampering.

0G Labs has built its own version of this stack and describes it in three layers: verifiable compute, Agentic ID and decentralized storage rated at 50 Gbps throughput. The company is a direct participant in the market its CEO was describing.

The x402 payment standard offered the strongest evidence that machine-to-machine settlement is already happening at scale. By mid-2026, x402 had processed more than 200 million transactions, according to figures cited at the conference.

Why banks and regulators showed up

KBW has traditionally drawn a crypto-native crowd. This year banks and policymakers joined them, and their interest tracks a practical problem. AI agents often cannot engage effectively with traditional financial systems, which leaves blockchain and stablecoin infrastructure as a plausible settlement layer for machine economies.

Korea's own policy agenda featured heavily in the discussions. Conversations covered the country's tokenized securities initiatives, the Bank of Korea's Project Hangang central bank digital currency pilot and developments around won-denominated stablecoins. Project Hangang tests how a digital version of the national currency might function, while won stablecoins represent the private-sector counterpart to that effort.

The country's tokenized securities framework is set to take effect in February 2027, a deadline that gives Korean regulators a concrete window in which to clarify how stablecoin and tokenization rules will interact.

What it means for builders

The message from Seoul was a direct challenge to general-purpose chains. If Heinrich and the other speakers are right, simply making existing blockchains faster will not suffice. Agents need identity, compute verification and storage designed in from the start, not bolted on afterward. For Layer 1 teams, that reframes infrastructure investment as a redesign question rather than a throughput race.

A caveat deserves mention. Several of the people arguing that blockchains need AI-specific infrastructure are also selling AI-specific infrastructure. That does not invalidate the argument, but it makes independent adoption data — such as x402's transaction count — more probative than keynote titles.

Korea presents an unusually dense test case for the thesis. The country combines a large retail crypto base, an active exchange sector represented by Upbit, a live CBDC pilot in Project Hangang, a tokenized securities framework taking effect in February 2027 and an ongoing debate over won stablecoins.

The metrics worth tracking from here are concrete: whether Agentic ID standards gain adoption beyond individual projects, whether x402 transaction volumes keep climbing, and how Korean regulators treat stablecoins as the February 2027 tokenized securities start date approaches.
