Dear Valued Customers,

Thank you for your continued support of Canaan and the Avalon Nano 3.

Since its launch, the Avalon Nano 3 has achieved impressive sales volumes and received a positive market response. This success has reinforced our confidence in contributing to the construction of the decentralized Bitcoin network.

Earlier this month, some vigilant community members reported potential security issues with the Avalon Nano 3. Our technical department promptly analyzed and evaluated these concerns. Through comprehensive analysis, we discovered a vulnerability in some of the Nano’s backend web pages related to unverified login credentials. Malicious Trojan programs within the LAN could exploit this vulnerability to submit mining pool configuration information to http://<yourIP>/get_home.cgi via the POST command, thereby stealing computing power. In response, we swiftly developed the necessary firmware updates and provided guidelines for using the Avalon Nano 3 in a secure network environment.

After urgent development and deployment efforts, the latest firmware version and Avalon Remote App were released on July 19, 2024. We request all Avalon Nano 3 users to update their Remote App to the latest version available on the Apple App Store and Google Play Store, and use it to upgrade the firmware on all Nano 3 devices in their local area network.

We sincerely thank our customers for their prompt feedback, which has been invaluable, and we've learned a lot. We are committed to continuously inspecting, analyzing, and enhancing the security of our products.

In designing the Nano, we have always respected user privacy and have not included any intentional backdoor programs. Starting in December, we will gradually open-source relevant programs and release open-source firmware to ensure enhanced security and transparency.

Additionally, we are offering a compensation plan for all customers who purchased the Avalon Nano 3 before July 19, 2024. Each Avalon Nano 3 will be eligible for a $10 coupon from the Canaan official store. Details on how to apply for this coupon will be provided in the next version of the Remote App. Please stay updated with the app for further information.

We firmly believe that the development of a decentralized network relies on the collective efforts of all blockchain participants. As a member of this community, Canaan remains dedicated to expanding the influence of blockchain technology, increasing the number of participants, and providing more convenient and user-friendly methods for blockchain engagement. Once again, we thank all our customers for their support, feedback, and encouragement. We will continue to strive to deliver better products to you.

Yours sincerely,
The Canaan Team

After your latest firmware update for Nano 3 my device is bricked, no Hash no nothing. Made factory reset, changed adapter, pools, nothing. Before that was working ok.
