Breakthrough innovation: Dogecoin and Solana achieve trustless cross-chain connection

Psy (formerly QED Protocol) announced the successful development of the first trustless bridge protocol, directly connecting Dogecoin to the Solana blockchain. This innovation not only brings the security of the Proof of Work (PoW) mechanism to Solana, but also allows the world's largest meme coin, Dogecoin (market value over $36 billion), to officially connect to the Solana ecosystem's decentralized application (dapps) network.

The bridge protocol enables direct "dialogue" between the two blockchains: Solana and Dogecoin can independently verify each other's transactions and consensus mechanisms without relying on a third-party trusted intermediary. This breakthrough not only strengthens cross-chain security, but also opens up huge opportunities for ecological synergy - Dogecoin's huge user base (market value of $36 billion+) will be able to access Solana's decentralized finance (DeFi), non-fungible tokens (NFT) and blockchain games for the first time, and Solana developers can also access Dogecoin's massive user base.

Technological innovation: subverting the traditional bridging model and directly addressing the industry's security pain points

Unlike traditional cross-chain bridges that rely on multi-signatures or custodians, Psy uses the next-generation proof-of-work technology to verify Dogecoin's PoW consensus mechanism directly on Solana. This "minimized trust" design directly hits the core vulnerability of crypto infrastructure - according to statistics, cross-chain bridge hacking has caused more than $2.8 billion in losses.

This move establishes Psy as a leader in PoW technology innovation in the Solana ecosystem: it successfully combines the security advantages of PoW with Solana’s high speed and programmability, proving that new PoW chains can securely interoperate with high-performance public chains without the need for centralized intermediaries.

Ecological value: two-way empowerment of developers and users

The bridge protocol supports mainstream Dogecoin wallets and exchanges for recharge. The specific operating mechanism is as follows:

• Cross-chain verification: By capturing and verifying Dogecoin block headers (including core data such as previous block hash, timestamp, difficulty target, Merkle root, etc.) on Solana, the transaction validity is confirmed cryptographically;

• Asset mapping: When a user transfers Dogecoin to the bridge protocol, the system verifies the deposit on the Dogecoin chain and mints an equal amount of QDOGE tokens on Solana; during reverse redemption, QDOGE tokens are burned on Solana, triggering the release of the original Dogecoin to the user's address through the Wormhole cross-chain message protocol.

Psy's Vision

This integration makes Psy an innovator in PoW technology in the Solana ecosystem, combining the security advantages of PoW with the speed and programmability of Solana. Psy’s mission is to empower developers to build hyper-scalable Web3 applications to drive the development of the next generation of the decentralized Internet.

To support the developer ecosystem, Psy also launched a full set of infrastructure tools:

• txindex: A full-featured Dogecoin indexer that easily handles fork scenarios

• electrs-doge: The first open source Dogecoin block explorer

• doge-sdk: The first Dogecoin JavaScript development kit

• forkr: An easy-to-use tool to simulate Bitcoin/Dogecoin fork reorganization

Industry leaders' comments

• Carter Feldman, CEO of Psy Protocol: “We have been committed to providing better services to the Dogecoin community for a long time, and now we are finally able to bring more practical value to DOGE. This achievement confirms the potential of combining top-level security mechanisms, user needs and a mature developer ecosystem.”

• Lily Liu, President of the Solana Foundation: “Dogecoin’s bridge to Solana is a milestone — we are inviting one of the most iconic communities in crypto to join the Solana ecosystem. DOGE, as the ‘pet of Bitcoin,’ perfectly interprets the fun and rebellious spirit of on-chain culture, and cross-chain integration will promote the deep integration of on-chain culture and DeFi.”
