We propose to continue development and support of the AdaStat.net Cardano blockchain explorer for the next 24 months. Planned work includes performance optimizations, improvements to UX/UI, and new features related to Cardano’s evolving governance model and on-chain tooling.

The frontend is developed using Vue.js and Tailwind CSS, which allows very small bundle size and fast loading time on different devices. The backend is built on Node.js and PostgreSQL, combining standard DB-Sync tables with custom-optimized indexes for high-speed data access. This dual approach enables advanced search and filtering across both on-chain and off-chain metadata — including DRep names, stake pool tickers, token labels, and more.

Infrastructure is horizontally scalable. Multiple backend servers work behind load balancer and handle traffic based on real-time utilization. This gives high availability and stable performance, even during peak usage.

It’s still a challenge to provide Cardano blockchain data in a way that’s both decentralized and easy to use. Blockchain explorers are key tools in solving this issue, as they provide access to information about blocks, transactions, stake pools, governance activities, and other on-chain operations. However, each explorer is also potential point of centralization — it can fail, or show incorrect data. Because of this, it is important for ecosystem to have several independent, performant, and open-source explorers.

AdaStat.net supports this goal by providing real-time, mobile-optimized, and feature-rich explorer for Cardano. Maintaining and improving AdaStat directly strengthens the ecosystem infrastructure, increase transparency of data, and offer valuable tool for SPOs, DReps, CC members, developers, and everyday users.

1. For SPOs: Real-time access to block production and stake pool performance, without delays from epoch boundaries or outdated data.

2. For DReps and CC members: Tools for tracking governance activities and accessing voting-related data in clear and transparent way.

3. For developers: Access to fully free REST API that provides Cardano data in easy-to-use JSON format — helpful for building tools, dashboards, or integrating blockchain data into other applications.

4. For general users: The site works smoothly on all devices, and we keep improving it based on user feedback.

5. For the Cardano ecosystem: AdaStat is a lightweight and open tool that helps Cardano stay decentralized and easy to understand - especially for new users. All of this helps Cardano grow: stronger infrastructure, clearer data, and better long-term adoption.

Over the 24-month period the Cardano community will receive a stable, high-performance, and continuously improving AdaStat Cardano blockchain explorer.

Key integrations include:

1. Ongoing infrastructure monitoring and uptime maintenance

2. Bugfixes and UI/UX improvements based on user feedback

3. Monitoring of upcoming Cardano HardForks and CIPs and prepare updates in advance

4. Collaborating (when appropriate) with other tools and services to stay compatible and relevant

Based on our experience, each team member contributes part-time (~1 hour per day), totaling ~100 hours/month. The proposal is structured as 24 monthly milestones (1 milestone = 1 month). Current salary rate in our country is $50/hour before all taxes, i.e. totaling $5,000/month. Additionally there are network Infrastructure costs ~$300/month.

TOTAL MONTH COSTS: $5,000 + $300 = $5,300

TOTAL PROJECT COSTS: $5,300 * 24 months = $127,200

1 ADA = 0.6 USD (current rate)

TOTAL: $127,200 = 212,000 ADA

Team:

1. Tetiana Stashenko - Product manager, Front-end developer

2. Dmytro Stashenko - Lead developer, founder of AdaStat.net

3. Mariya Turlak - UX/UI Designer

4. Olha Domornikova - QA Engineer

Duration:

• 24 months, which corresponds to 24 Milestones (1 Milestone = 1 Month)

AdaStat.net has been actively developed and maintained since Shelley Incentivized Testnet in 2019, with consistent uptime, feature updates, and strong organic community usage. The team has years of experience working with Cardano node, DB-Sync, performance tuning, database optimization, and community engagement. This shows that we’ve been consistently improving the project over the years, and we plan to keep doing so.

After the initial 24-month funded period, we plan to continue maintaining and evolving AdaStat through:

Efficient architecture and low overhead: The platform is optimized for performance and cost-efficiency, allowing us to sustain operations with minimal resources.

Open-source contributions: By keeping the code simple and well-documented, we hope contributors from the Cardano community will join via GitHub.

Collaborations within the ecosystem: We are open to lightweight integrations with other tools (wallets, governance tools, dapps, etc) that can help share maintenance effort and expand utility.

Future grants: If needed, we may apply for other grants (including applying through other grant systems, such as Catalyst)

Most importantly, AdaStat will remain free, neutral, and privacy-friendly - with no ads, no tracking, and no monetization. Our goal is simple: to keep AdaStat relevant and helpful as Cardano changes and grows.

AdaStat is widely used and referenced within the Cardano ecosystem. While it does not have formal partnerships with particular projects, it is regularly mentioned by developers, SPOs, and other ecosystem participants as a stable and fast source of blockchain data. Many wallets and platforms set AdaStat as their default explorer or provide direct links to it for more detailed views. The website and its public API serve approximately 20,000 unique users per month — based solely on server-side logs, as AdaStat does not use tracking scripts, analytics services, or even cookies. This strong organic usage reflects a high level of trust and recognition from the community, achieved without any active promotion.
