Why Exchanges Are Building Their Own Blockchains

In this interview sit down with Kyle Jenke, Chief Business Officer at Optimism, to discuss why 2026 could be a defining year for blockchain adoption among the world’s largest financial institutions.

Kyle explains how Optimism helps enterprises build and operate their own blockchains using the OP Stack, infrastructure that powers major networks including Base, Kraken’s Ink, OKX, Sony’s blockchain initiatives, and other leading digital asset platforms. With billions of transactions flowing through OP-powered chains, the conversation highlights how blockchain infrastructure is moving beyond experimentation and into large-scale commercial deployment.

The discussion explores the growing trend of exchanges and financial institutions launching their own blockchain networks rather than relying on shared public infrastructure. According to Kyle, owning a blockchain allows organizations to customize products, capture economic value, and maintain greater control over security, compliance, and privacy. As competition intensifies between traditional financial institutions, fintechs, and crypto-native companies, infrastructure ownership is becoming a critical strategic advantage.

The interview also examines the rapid growth of on-chain activity, with OP Stack-powered ecosystems generating significant transaction volume and application revenue. What once took months to achieve is now happening in days, demonstrating how quickly blockchain adoption is accelerating across global markets.

Regulation is another major focus, with Europe leading through frameworks such as MiCA and DORA, while the US and Asia continue advancing toward greater regulatory clarity. Kyle argues that the next 12 to 18 months could represent a pivotal moment as enterprises decide which blockchain infrastructure will power the future of financial services.
