Polyhedra Network: Building the Largest Interoperable Bitcoin Ecosystem with zkBridge

Bitcoin, the very first blockchain, is evolving continuously, and its ecosystem is currently experiencing rapid expansion since the emergence of the Ordinals protocol. To foster further growth of a robust Bitcoin ecosystem, there is a pressing need for a solution that not only enables seamless interactions within Bitcoin and its Layer-2 networks but also facilitates interoperability between the Bitcoin ecosystem and other blockchain ecosystems like Ethereum and Ethereum Layer-2s.

Addressing this need for interoperability, Polyhedra Network introduced the Bitcoin Messaging Protocol powered by zkBridge. This pioneering development expands Bitcoin’s functionality, enabling it to interact seamlessly with a range of blockchain networks, both Layer-1s and Layer-2s.

zkBridge, the interoperability protocol designed and implemented by Polyhedra Network, offers a trustless and efficient cross-chain solution powered by zero-knowledge proofs, not only within the Bitcoin ecosystem but also between Bitcoin and other blockchain networks.

Bitcoin Messaging Protocol with zkBridge

As the first trustless interoperability protocol between Bitcoin, Ethereum, and other networks, we are working together with developers building cutting-edge infrastructures, Bitcoin Layer-2s, wallets, DeFi protocols, and tools within the Bitcoin ecosystem. Our zkBridge Bitcoin interoperability protocol will help the Bitcoin ecosystem to reach the entire crypto user base, securely and efficiently. Assets will no longer be constrained to the Bitcoin network itself or any other blockchain network. Developers can focus on building value-add projects without worrying about connecting Bitcoin with other chains. Complexities around wallets and accounts can be abstracted away, allowing developers to focus on bringing incredible user experiences. zkBridge enables fast, secure, and trustless cross-chain interactions, utilizing zero-knowledge proofs to eliminate the need for any third-party validation.

Leveraging zkBridge, Bitcoin can now securely transmit its current and historical data, utilizing zero-knowledge proofs, to 20+ networks including Bitcoin Layer-2s, Ethereum, and Ethereum Layer-2s. It is also compatible with recent Bitcoin innovations like Ordinals, BRC-20, and Atomicals. This enables smart contracts on other blockchain networks such as Ethereum and Bitcoin Layer-2s to trustlessly access Bitcoin data and protocols, and make all kinds of computing logics, and the security is guaranteed by zero-knowledge proofs.

Furthermore, when we want to send messages and cross-chain transfer assets from another blockchain to Bitcoin, we need to overcome Bitcoin’s lack of smart contract functionality. Our solution employs a Proof-of-Stake mechanism. Validators stake tokens from sender chains and are authorized to write data on Bitcoin, ensuring secure cross-chain transactions. We further enhance our solution by integrating with EigenLayer and Babylon, and introducing a well-designed slashing mechanism for crypto-economic security.

  • Ledger Confirms Unauthorized Hardware Implant in Devices, Losses May Exceed $86 Million

    On October 11, Cointelegraph reported that hardware wallet manufacturer Ledger confirmed the presence of unauthorized hardware implants in the devices of an affected user. The incident involves losses related to devices purchased from its Southeast Asian distributor, CryptoBilis. Investigator Specter estimates that the losses may exceed $86 million, involving Bitcoin, Ethereum, and Tron. Ledger stated that it is in contact with the affected users; CryptoBilis has confirmed the suspension of all hardware wallet inventory sales until the investigation is complete. Ledger claims that the incident appears to be limited to this single distributor and its market, and that its own infrastructure, systems, and services have not been compromised. The company has not yet confirmed the number of affected customers or the total amount of losses. Ledger advises users who have not initialized their devices to refrain from doing so, while those who have already initialized their devices may consider transferring their assets to a new signer using a new mnemonic.

  • Anthropic Model Automatically Submits False Leads to Philadelphia Police

    On October 11, according to CCTV International News, the AI model 'Claude Haiku 4.5' from Anthropic automatically accessed the Philadelphia Police Department's webpage for unsolved homicide tips in July this year, filling out a form claiming to have 'potential information related to the case' but did not provide a name or contact information. The form was subsequently marked as spam by the police and did not trigger an investigation. Anthropic released a report on October 9 disclosing the incident and notified the Philadelphia police in advance. The police stated they were previously unaware of the situation, deemed it 'unacceptable,' and requested that technology companies take necessary measures to prevent their AI systems from submitting false information to law enforcement.

  • Industrial Fulian: US International Trade Commission Initiates 337 Investigation Against Company and Subsidiary

    On October 11, Industrial Fulian announced that it was informed the US International Trade Commission officially launched a 337 investigation on October 9 local time, regarding patent infringement claims made by Vicor Corporation. Vicor accuses the company and its subsidiary of infringing on a patent for a 'vertical power supply system.'

  • CFTC Issues Two Proposals Clarifying Prediction Markets as Derivatives, Excluding Casino Gambling

    On October 11, Cointelegraph reported that the U.S. Commodity Futures Trading Commission (CFTC) has released two proposals to clarify its regulatory authority over prediction markets. The first proposal defines event contracts related to sports, politics, culture, and weather as 'swaps' products under federal law. CFTC Chairman Michael Selig stated that these products fall under the category of commodity derivatives as defined by the Commodity Exchange Act, and are fully within the exclusive jurisdiction of the CFTC. The second proposal establishes boundaries, explicitly stating that traditional casino-style gambling products—including sports betting and casino games—do not fall within the definition of 'swaps' and are not considered derivatives. This move comes in the context of prediction market operators like Kalshi and Polymarket facing joint lawsuits from multiple states, accused of operating illegal gambling businesses; the CFTC is counter-suing and issuing new regulations in an attempt to clarify the regulatory boundaries between federal and state authorities, paving the way for a potential Supreme Court ruling.
