In a recent Midweek with Max, E. G., co-founder of Infura, shared the vision behind DIN and why it’s a game-changer for Hemi. Traditional RPC setups struggle under traffic spikes. Single providers buckle, users leave, and trust—once lost—is hard to regain. DIN changes this by creating an on-chain registry and marketplace for RPC providers, allowing builders to discover services, pay in crypto, and route requests across multiple operators. No more cumbersome credit card setups or endless email threads—everything is streamlined and decentralized.

Hemi is already handling real traffic at scale, pushing close to 100 TB of RPC in a single month. By distributing load across multiple providers, DIN not only increases throughput but also reduces risk when failures occur. The principle is simple: diversity equals resilience. Builders can select two providers, ten, or more, and dynamically route traffic according to demand, improving uptime and reliability.

DIN acts as a programmatic discovery layer for L1s, L2s, and other APIs. Providers list their services on-chain, builders discover them effortlessly, and payments settle through crypto rails. Initially developed in the EVM ecosystem, DIN is evolving to meet Hemi’s multi-chain requirements, especially where Bitcoin and Ethereum intersect. Builders increasingly need Bitcoin data alongside HVM calls. While Bitcoin views are currently accessible through HVM precompiles, this can add latency. DIN aims to serve Bitcoin reads in parallel, enabling apps to reflect Bitcoin events instantly, even before HVM observes them.

Although Bitcoin Core RPC is robust, it doesn’t provide full indexing for common dApp use cases, such as address lookups or rich queries. EVM ecosystems solved this years ago with layered indexing. DIN pushes shared standards and open-source code, ensuring operators meet a higher bar and provide consistent, reliable services.

Recent updates show Hemi’s growing integration. The MetaMask fee API now supports Hemi, meaning gas estimates are more accurate, benefiting both builders and users. DIN also offered an introductory perk: users could use code BDCFI for 50% off their first bill, with further details shared on Discord and social channels.

Hemi Protocol Updates

Hemi continues to innovate across multiple fronts. ZK provability is nearing full settlement to Ethereum, starting with a 24-hour window and gradually reducing to 2–3 hours as the path is hardened. This development also underpins hbitVM, Hemi’s secure Bitcoin tunneling system using challengeable flows and broad participation, contributing to public-good infrastructure.

Safety and reliability remain a focus. End-to-end tests for L1 contract upgrades are wrapping up in controlled environments before deployment to testnet and mainnet. Backend work for OG role claims is underway, linking EVM addresses, with frontend verification following. Similarly, VeriBlock claims and PoP payouts are resuming after updates from Singapore, with testnet deployment scheduled before mainnet release. The new payout algorithm is designed to accommodate Bitcoin fee spikes efficiently.

Incentives and the Next Phase

Hemi’s Season 2 of incentives is shifting from long, slow-accounting cycles to faster, more liquid rewards. While some point-style sprints remain, the emphasis is on quick feedback and clear yield, with a combination of liquid and staked rewards, and occasional non-HEMI partner incentives.

Near-term priorities include ZK provability to Ethereum, building hbitVM, and decentralizing sequencer and publisher roles, alongside improvements to HVM. Longer-term, Hemi is planning Chain Builder for L3s, allowing custom execution with full access to assets from both Bitcoin and Ethereum through the tunnel.

Builder Recommendations

For builders shipping on Hemi, testing DIN is essential. Split traffic, measure error budgets, and run failover drills. Observe MetaMask fee behavior and plan for parallel Bitcoin reads alongside HVM calls. If you require advanced indexing, Hemi can connect you with the right support and providers.

The key takeaway: decentralization matters most under pressure—at block zero, during peak traffic, or in the middle of the night. DIN makes decentralized RPC practical, and Hemi ensures it’s useful across chains, delivering real-world utility for builders and end users alike.
