MENGENAI EPISOD INI
Joshua Sum is the Chief Product Officer at Solayer, a hardware accelerated network built to move money at the speed of metal. Joshua joins Andy Pickering to explain how dedicated chip-level infrastructure is pushing blockchain throughput into territory no software-only chain can reach — and why that matters as payments, AI agents, and real-world asset tokenization all converge on the same rails.
Why you should listenJoshua's path to crypto ran through direct-to-consumer e-commerce, a founding quant role at Treehouse, and building CollegeDow into the largest university blockchain network in the world, spanning around 120 campuses globally. He joined Solayer as a founding engineer and has grown with the company over two years into his current role leading product across multiple lines. He walks through how Solayer evolved from pioneering restaking on Solana — using it as a tool to improve transaction reliability and throughput — into building a full hardware accelerated Layer 1 that uses the Solana Virtual Machine but separates consensus across dedicated machines connected by low-latency, high-bandwidth equipment. The result is battle-tested performance of 200,000 to 300,000 transactions per second using messy, real-world transaction types, not the synthetic benchmarks that get loosely thrown around in the space.
The conversation covers Solayer's $35 million ecosystem fund and why the team deliberately avoided a grants model in favour of a venture approach, investing in founders building sustainable, revenue-generating businesses rather than handing out free money for narrative-driven experiments. Joshua walks through three early-stage portfolio projects: Docs Exchange, a full-suite DeFi trading platform; BuffTrade, an AI agent launchpad where bots trade on your behalf and back their tokens with actual strategy performance; and SpoutFi, which tokenizes equities and lets users borrow against them the way high-net-worth individuals already do — without selling, and without triggering a tax event. Each use case maps directly back to the throughput thesis: more agents, more users, more overlapping state means you need a chain that can actually handle the load.
Joshua also breaks down Solayer's consumer-facing push through Solayer Pay, which includes a mobile app, rotating private addresses for peer-to-peer transfers, and the Emerald crypto card with built-in travel rewards and partner airdrops. He explains why the chain will launch with SOL as its gas token — removing the onboarding friction that kills adoption on new L1s — before introducing a dual-token model with LAYER as the ecosystem matures. The episode closes with Joshua's take on the current market: tough conditions are positive for the long term because they flush out narrative-driven projects and reward teams building real products with real revenue, which is exactly where Solayer wants to be.
