This Hackathon aims to encourage developers to actively participate in the development practices on the Alaya testnet. Hackathon offers a prize pool with the equivalent of $100,000 in ATP, including: the initial bonus of ATP equivalent to $50,000, distributed according to the number of votes of the project based on the quadratic algorithm. the special jury bonus of ATP equivalent to $50,000, to incentivize outstanding projects in the Alaya ecosystem. 50,000 USD for the privacy computing track prize pool. 20,000 USD for a special award for quality projects. We encourage participants to create innovative blockchain projects, including infrastructure, applications, peripherals, etc. The following are some ideas and suggestions from the Alaya community and the participating judges.
The layer provides a reliable and secure foundation for the upper application layer, and mainly includes the protocol code and basic hardware facilities on the lowest layer of the blockchain.
-
The underlying protocol
The underlying protocol is the lowest and most basic part of blockchain applications. It maintains network node and enables API calls. It is built mainly through technologies such as network programming, encryption algorithms, and data storage.
-
Anonymity technology
Anonymity technology is used to solve user privacy issues.
-
Security optimization
Consensus security, transaction security, etc.
-
Peripherals (explorers, wallets, and tools)
Peripherals provide users (users/developers in the ecosystem) with various convenient, usable and easy-to-use services.
This layer mainly provides high-level APIs for blockchain application developers to build practical blockchain applications.
-
Smart contract
That is, a "programmable contract". A smart contract allows credible transactions without a third party. These transactions are traceable and irreversible. Generally speaking, when the set conditions are met, the contract is automatically executed. It represents a major direction for the future development of blockchain.
-
Cross-chain
Among the many problems facing blockchain, network isolation hinders the collaborative operation of different blockchains, which greatly limits the development space for blockchain. Cross-chain technology is the key to realizing the value of the Internet. In simple terms, by cross-chain, a communication protocol can be executed from one chain to another. The two chains can be a parent chain and a child chain, or they can be side chains.
-
Layer 2 network
Layer 2 pursues the ultimate performance. Layer 2 network can reduce the burden on Layer 1 by sharing most of its computation workload, thereby improving service processing efficiency and achieving scaling. Layer 2 can only achieve partial consensus, but it can meet the needs of various scenarios.
-
Privacy-preserving computation
Current models mostly rely on the training of massive data, and the demand for massive data has led to the raging data privacy issues. Privacy-preserving computation can aggregate computation and train models using data scattered across multiple parties without aggregating massive data, while making the data of each party unexposed throughout the process, e.g. the migration of Ethereum-related privacy-preserving projects.
-
Information security
It is used to secure the development and the information on the blockchain, and to provide blockchain application developers with a safer development environment and security audits.
-
DAO
DAO, a form of organizational structure based on the blockchain, aims to make an organization, upon its establishment, comply with specific specifications through smart contracts. It adjusts all participants' privileges through a contract mechanism.
-
BaaS
BaaS is a decentralized platform built on the existing blockchain technology and protocols, and provides service examples based on public chains.
With the basic protocol layer and the general application layer, blockchain can be used in many specific industries, leading a new round of innovation.
-
Authentication
It is mainly used to authenticate the identity, account, address and contract content of users participating in the transaction.
-
Payment
As an important part of blockchain finance, it aims to solve the issues of trust, security and anonymity in transactions, realize streaming payment, process funds in real time, and ensure real-time payment by both parties within the agreed time period.
-
NFT
The important features of NFTs include: each NFT has one unique identification; NFTs are neither interchangeable nor divisible. More importantly, each NFT represents a value that is different from the other. NFT has set off an upsurge in collectibles and entertainment fields.
-
Fintech
The blockchain technology can solve the trust and security issues in transactions, and has thus become an alternative direction for the future upgrade of the financial industry. Through the blockchain, people can trade without any third-party credit intermediaries, reducing the cost of asset transfer on a global scale.
-
Storage
Blockchain can guarantee the security of stored files. With the help of blockchain-based decentralized cloud storage, data retention and transmission are more secure. At the same time, since every change in blockchain transactions can be tracked and recorded in distributed and public ledgers, blockchain storage becomes an ideal choice for keeping any form of financial transaction records that require audit management.
-
Data service
It mainly provides three services: data sharing, database and data preservation, for example, Oracle chain, Streamr, and The graph.
-
Law
The legal application of distributed evidence of blockchain is mainly embodied in three aspects: copyright protection, evidence preservation, and electronic smart contracts.
-
Energy
Blockchain is widely used in the energy industry, and provides data for energy service operators, for example, carbon neutrality.
-
DeFI
DeFi, or Decentralized Finance, is broadly defined as new forms of financial products, aiming to create a distributed and more competitive financial system in an open, open-source, and barrier-free blockchain ecosystem and realize distributed transactions in the global market. It involves underlying infrastructure, financial infrastructure, and user interaction interface, e.g. Maker, Uniswap, etc.
-
Data application scenarios
Map ugc, global battery recycling, global logistics information tracing, etc.
We welcome developers to experiment on the Alaya development testnet based on open-source ecosystem projects. Examples are as below;
-
Private transactions-Tornado Cash is a private transaction middleware implemented on Ethereum based on zero-knowledge proof (ZKP). It uses zk-SNARK and can *send ETH and ERC20 tokens (DAI, cDAI, USDC, USDT, and WBTC) to any address in an untraceable manner;
-
Identity authentication-The decentralized identity management system can generate a unique identity on the chain for users, allowing unified identity authentication across applications. It can be scaled to multiple authentication and cross-validation;
-
"Stateless", light (stateless) nodes can verify all transactions and all parts of the state without materially storing any state. Statelessness allows the various states of/stateless existence of light clients, and each state requires different specifications to make nodes easier to access. One example is the Mina protocol.

本次 Hackathon 旨在让开发者积极参与 Alaya 开发测试网络上的开发实践， Hackathon 总奖金池 17 万美元等值ATP，其中包括：初始奖金池 5 万美元等值ATP，根据项目的投票人数基于二次方算法分配。评委特别奖金 5 万美元等值ATP，用于激励 Alaya 生态中的优秀项目。5万美元为隐私计算赛道奖金池。2万美元为优质项目专项奖励。我们鼓励参赛者产出具有创新性的区块链项目，包括基础设施、应用、工具周边开发等，以下是来自 Alaya 社区及参赛评委 的一些想法和建议
为上层应用层提供可靠、安全的基础，该层主要包括了提供区块链最底层的协议代码和基础硬件设施。
-
底层协议
是区块链应用中最底层最基础的部分。维护网络节点，提供API调用，主要使用网络编程、加密算法、数据存储等技术来构建。

该层主要面向区块链应用开发者提供高层API以便构建实用的区块链应用。
-
智能合约
即“可编程合约”，智能合约允许在没有第三方的情况下进行可信交易，这些交易可追踪且不可逆转。一般而言，达到设置的条件时，合约自动执行，这是未来区块链发展的一个重要方向。
-
跨链
在区块链所面临的诸多问题中，网络孤立性阻碍了不同区块链之间的协同操作，极大程度的限制了区块链的发挥空间。跨链技术就是实现价值互联网的关键，简单来说，跨链就是实现一个链到另一个链的通信协议，这两个链的关系可以是母链和子链，也可以互为侧链。
-
二层网络
Layer2 追求极致的性能，作为二层网络，可以替 Layer1 承担大部分计算工作，降低一层网络的负担，提高业务处理效率，从而实现扩容。Layer2 只能做到局部共识，但是可以满足各类场景的需求。
-
隐私计算
当前的诸多模型大多依赖海量数据的训练，对于海量数据的需求导致了数据隐私问题的泛滥。而隐私计算可以实现在不聚合海量数据的前提下利用分散在多方的数据完成聚合计算和模型训练，保证整个过程中每一方的数据都不会暴露出来，例如以太坊相关的隐私项目移植。
-
信息安全
用于保障开发的安全性以及区块链上信息内容等安全性，给区块链应用开发者提供更加安全的开发环境和安全审计。
-
DAO
一种基于区块链的组织结构形式，目标是使组织从创立之初，便通过智能合约，约定组织的行为，使其遵守特定的规范。通过合约机制，调整所有参与人的权利和权益。
-
BaaS
BaaS是基于现有的区块链技术和协议开发的去中心化平台，提供基于公链的服务实例。
有了基础协议层和通用应用层的保驾护航，区块链可以被用于诸多具体行业中，引领了新的一轮行业的变革。

-
金融科技
应用区块链技术可以解决交易中的信任和安全问题，因此区块链技术成为了金融业未来升级的一个可选的方向，通过区块链，交易双方可在无需借助第三方信用中介的条件下开展经济活动，从而降低资产能够在全球范围内转移的成本。
-
存储
区块链可以保证存储文件的安全性。借助基于区块链的分散式云存储，数据的保留和传输更加安全。同时，由于区块链交易中的每项变更都可以在分布式和公共分类账中进行跟踪和记录，这使区块链存储成为保存需要审计管理的任何形式的金融交易记录的理想选择。
-
