Dear Community Users, Developers, and Partners: Thank you for your attention and support regarding the testing of the CKB explorer developed by APP5 team over the past period. Following the joint testing and evaluation efforts with the Nervos team, and based on current overall product planning, resource allocation, and ecosystem collaboration considerations, both parties have decided to adjust the explorer product roadmap: ➡️ The CKB explorer explorer.app5.org developed by the APP5 team will cease its testing phase and be taken offline; ➡️ The original explorer explorer.nervos.org will continue to operate stably as the current official explorer service portal. 🔔 It is important to note that: This shutdown is a adjustment to the product and cooperation arrangements. ✅ The operation of the official CKB explorer will not be affected. ✅ The official CKB explorer will continue to provide normal query services for blocks, transactions, addresses, contracts, etc. ✅ The results achieved by the APP5 CKB explorer during the testing phase have completed their established verification goals and have been successfully applied to the optimization of the original explorer. 📅 The subsequent arrangements are as follows: The new explorer test entry will be officially taken offline: 2026/4/10, 12:00, UTC+08:00 During the cooperation, our team has invested heavily in explorer architecture, user experience, performance optimization, and related functions. We also thank the Nervos team for their cooperation and support during the testing phase. This adjustment is a prudent decision based on the current overall development pace. We respect the Nerovs team's current product choices and look forward to continuing open cooperation in the future in suitable directions. Thank you for the understanding and support of community users, developers, and partners. 🙌 📂 Attached are the open-source repositories related to this testing phase. Developers are welcome to further explore, build upon to these codebases.🔧 Node: github.com/appfi5/ckb/tree/e… Frontend: github.com/appfi5/ckb-explor… Task Processing: github.com/appfi5/ckb-explor… API: github.com/appfi5/ckb-explor… Documentation: github.com/appfi5/app5-ckb-e… APP5 LABS #CKB #CKBExplorer #Web3 #Nervos

Dear CKB Community, To ensure a smooth transition between the old and new CKB explorer API services, and due to the fact that some users have not yet completed the API migration process—combined with comprehensive considerations regarding core technical factors such as API compatibility——we have decided, after thorough discussion with the Foundation, to postpone the originally scheduled launch and switchover of the new CKB explorer. The specific launch timeline will be announced separately based on the overall progress of API integration. We sincerely appreciate your continued support and understanding!
