Current survey systems lack transparency and data integrity. We aim to build a Cardano-based decentralized survey platform to ensure secure, tamper-proof, and verifiable survey data for all users.
This is the total amount allocated to HYDRA-Cardano based Survey Platform.

Use Cardano L1 to create survey and publish result. The responses, validation and aggregator will settle on Hydra (L2) to reduce fee and optimize performance while maintaining security and reliability
No dependencies.
We will open source the smart contract under Apache 2.0 license
Problem:
Current survey systems lack transparency and data security and are expensive to implement. This leads to the risk that data can be altered or tampered with, and there is no way to verify the integrity of the results. We aim to build a decentralized survey platform using Cardano blockchain technology to ensure that survey data can be verified at the lowest cost.
Approach: Our approach is based on the following key points:
- Survey will be created on Cardano mainchain, including survey name, description, questions and some parameters like ending date
- Responses of user will be created on Hydra L2. There is a lot of responses, no limitation about fee and validation of response will be ensured
- Aggregator for final result transaction will happen on L2 without any fee and ignoring limitation about tx size of huge number of input (responses)
- Final result will be brought back to L1, attach with significant of hash data which happend on L2
Our project will attract many users in the Cardano community:
- Organizations that want to conduct surveys.
- Individuals who participate in surveys.
In particular, organizations and businesses that require high integrity and security in collecting opinions will benefit from our system.
Many different types of surveys can be run on our platform, for examples:
- Customer satisfaction surveys
- Employee satisfaction surveys
- Market research surveys
- Political polls
- Social media surveys
The system will provide features to check transactions on the blockchain for both L1 and L2. Survey results will be verified using blockchain explorer tools to ensure objectivity and data integrity. Customers can clearly assure survey participants that their responses will be confidential and cannot be changed once recorded.
問題点:
現在の調査システムは透明性やデータの安全性に欠けており、導入コストが高いです。そのため、データが改ざんされるリスクがあり、結果の正確性を検証する手段がありません。私たちは、Cardanoブロックチェーン技術を活用した分散型の調査プラットフォームを構築し、最低限のコストで調査データが検証できるようにすることを目指しています。
アプローチ:
私たちのアプローチは以下の主要なポイントに基づいています:
私たちのプロジェクトは、Cardanoコミュニティの多くのユーザーを引きつけるでしょう:
特に、意見収集において高い誠実性と安全性を必要とする組織や企業は、私たちのシステムから大きな利益を得るでしょう。
さまざまな種類の調査が私たちのプラットフォーム上で実施できます。例としては:
システムは、L1とL2の両方でブロックチェーン上のトランザクションを確認する機能を提供します。調査結果はブロックチェーンエクスプローラーツールを使用して検証され、客観性とデータの完全性が保証されます。顧客は、参加者に対して、回答が記録された後に変更されることはなく、秘密が守られることを明確に保証できます。
Problema:
Los sistemas de encuestas actuales carecen de transparencia y seguridad de datos, y son costosos de implementar. Esto conlleva el riesgo de que los datos puedan ser alterados o manipulados, y no existe una forma de verificar la integridad de los resultados. Nuestro objetivo es construir una plataforma de encuestas descentralizada utilizando la tecnología blockchain de Cardano para garantizar que los datos de las encuestas puedan ser verificados al menor costo.
Enfoque:
Nuestro enfoque se basa en los siguientes puntos clave:
Nuestro proyecto atraerá a muchos usuarios en la comunidad de Cardano:
En particular, las organizaciones y empresas que requieran alta integridad y seguridad en la recolección de opiniones se beneficiarán de nuestro sistema.
En nuestra plataforma se pueden realizar diferentes tipos de encuestas, por ejemplo:
El sistema proporcionará funciones para verificar transacciones en la blockchain tanto para L1 como para L2. Los resultados de las encuestas serán verificados utilizando herramientas de exploración de blockchain para garantizar la objetividad y la integridad de los datos. Los clientes podrán asegurar claramente a los participantes de la encuesta que sus respuestas serán confidenciales y no podrán ser modificadas una vez registradas.
Promoting Technology Adoption: By successfully deploying projects on the Cardano L1 and Hydra L2 blockchain platforms, we demonstrate the soundness and usefulness of the technology. This inspires developers to explore similar projects, contributing to the knowledge base and innovation within the Cardano community. At the same time, our platform encourages other projects to apply blockchain technology to real-world use cases, promoting an increasingly developed and useful Cardano product ecosystem.
Enhancing Transparency and Trust: We actively promote community opinions, transparency, and trust in data collection. Our decentralized survey platform empowers individuals and groups to collect and share opinions without fear of censorship or manipulation, enhancing transparency and trust in the data collection process. This helps the Cardano community promote true decentralization, fostering a culture of openness and accountability.
Effective Cost-Effectiveness and Accessibility: We use Hydra L2 to collect and aggregate responses, reducing transaction fees and making large-scale surveying easier for a wide range of clients, including nonprofits, research groups, and individual users.
技術採用の促進: Cardano L1およびHydra L2ブロックチェーンプラットフォーム上でプロジェクトを成功裏に展開することで、その技術の健全性と有用性を示します。これにより、開発者は同様のプロジェクトを探求するインスピレーションを受け、Cardanoコミュニティ内の知識ベースとイノベーションに貢献します。同時に、私たちのプラットフォームは他のプロジェクトがブロックチェーン技術を実世界のユースケースに適用することを促進し、ますます発展し、役立つCardano製品エコシステムを推進します。
透明性と信頼の向上: 私たちはコミュニティの意見、透明性、データ収集に対する信頼を積極的に促進します。私たちの分散型アンケートプラットフォームは、個人やグループが検閲や操作の恐れなく意見を収集・共有できるようにし、データ収集プロセスにおける透明性と信頼を向上させます。これにより、Cardanoコミュニティは真の分散化を推進し、オープン性と説明責任の文化を育むことができます。
コスト効率とアクセスの向上: Hydra L2を使用して応答を収集および集約することで、取引手数料を削減し、非営利団体、研究グループ、個人ユーザーなど幅広いクライアントにとって大規模なアンケート調査を容易にします。
Fomento de la adopción tecnológica: Al desplegar con éxito proyectos en las plataformas blockchain de Cardano L1 y Hydra L2, demostramos la solidez y utilidad de la tecnología. Esto inspira a los desarrolladores a explorar proyectos similares, contribuyendo a la base de conocimiento e innovación dentro de la comunidad de Cardano. Al mismo tiempo, nuestra plataforma fomenta que otros proyectos apliquen la tecnología blockchain a casos de uso del mundo real, promoviendo un ecosistema de productos Cardano cada vez más desarrollado y útil.
Mejora de la transparencia y la confianza: Promovemos activamente las opiniones de la comunidad, la transparencia y la confianza en la recopilación de datos. Nuestra plataforma descentralizada de encuestas permite a individuos y grupos recopilar y compartir opiniones sin temor a la censura o manipulación, mejorando la transparencia y la confianza en el proceso de recopilación de datos. Esto ayuda a la comunidad de Cardano a promover una verdadera descentralización, fomentando una cultura de apertura y responsabilidad.
Mayor rentabilidad y accesibilidad: Utilizamos Hydra L2 para recopilar y agregar respuestas, reduciendo las tarifas de transacción y facilitando la realización de encuestas a gran escala para una amplia gama de clientes, incluidas organizaciones sin fines de lucro, grupos de investigación y usuarios individuales.
