Akash (AKT)：基於區塊鏈的去中心化雲端運算市場

目前正在展開的人工智慧（AI）革命在消費者和企業中引起了極大的熱情。

Akash（AKT）是一個區塊鏈平台，促進CPU、GPU、記憶體和儲存容量等運算資源的去中心化交易。該平台自 2018 年開始，於 2023 年 8 月推出超級雲，增加了以人工智慧為中心的 GPU 容量交易功能。該平台的原生加密資產 AKT 用於治理、質押、購買計算資源的訪問權以及向資源提供者提供激勵付款.

Akash 是一個基於區塊鏈的分散式雲端運算市場，可實現 GPU、CPU、薄膜和儲存等硬體資源的交易。為了實現這一目標，它將受加密貨幣獎勵激勵的資源提供者和需要以靈活、負擔得起且易於使用的方式存取此類容量的資源消費者聚集在一起。 Akash 是使用 Cosmos SDK 和 Tendermint Core 構建的，這是基於 Cosmos 的區塊鏈更廣泛的生態系統的一部分。它使用委託權益證明 (DPoS) 區塊驗證模型。

Akash 計畫由 Overclock Labs 於 2018 年創立，該實驗室是由 Greg Osuri 和 Adam Bozanich 創立的軟體開發機構。該平台的主網於 2020 年 9 月啟動。最初，Akash 網路提供對分散式 CPU、記憶體和儲存容量的存取。 2023 年，該平台認識到人工智慧服務的爆炸性增長以及 GPU 運算在實現資源匱乏的人工智慧運算方面的重要性，推出了超級雲，這是 Akash 主網第六次迭代的一部分。超級雲端引進了在網路上交易 GPU 容量的功能。

The pivotal sixth mainnet upgrade also introduced the option for resource consumers to pay for access to computing capacity in USDC stablecoin, in addition to the option to pay in AKT coins. This helped ensure cost stability for resource users who had previously depended upon AKT's market price fluctuations when leasing Akash's services on a long-term basis.

Akash's architecture includes four principal components.

Blockchain Layer: Provides the core security and consensus mechanism.

Application Layer: Manages and regulates deployment and resource allocation.

Provider Layer: Includes tools and applications that help resource providers supply their computing capacity to the network.

User Layer: Comprises the interface and tools for resource consumers, known as tenants, to utilize the computing capacity offered by the platform to deploy their apps.

Besides providers and tenants, another key role on the network is that of validators. Akash validators don't participate in the distributed hardware resource trade. Instead, their job is to provide transaction validation services to keep the overall platform functioning and free from security threats.

Akash uses a reverse auction system in its decentralized marketplace to enable trade in computing resources. Tenants can deploy apps in three easy steps:

Choose a template or customize their app.

Find a provider according to their preferences.

Deploy and manage the apps.

Resource providers then offer their bids to meet the users’ requirements. The lowest bidder gains the right to provide the requested resources. Thanks to the competitive reverse auction mechanism, Akash represents a cost-effective alternative to traditional cloud providers for resource consumers.

Providers can gain access to reverse auctions held on the network by installing and running provider node software and staking AKT coins. The number of active providers on the network fluctuates depending upon the ongoing activity. As of Aug 15, 2024, there are close to 70 resource providers offering their services on the Akash network from locations all over the world.

Akash boasts a thriving ecosystem of tools and apps. Below are some of the main apps deployed on its network.

Akash Console provides tenants with the tools to easily source computing capacity from the network. In order to start leasing hardware resources on Akash, users first need to create a virtual container that specifies their resource requirements. Alternatively, they can choose from pre-made templated containers. The Console app makes it easy to deploy containers, evaluate bids from providers, choose a provider and monitor their performance.

Praetor App is the main interface for resource providers to offer bids and manage their capacity provision on the platform. It allows providers to interact with the network using a set of easy-to-use graphical user interfaces (GUIs) as alternatives to command-line options. Using Praetor App, providers can set up virtual machines and join the network as multi-server or single-server resource suppliers.

AkashChat is a generative AI tool similar in concept to the highly popular ChatGPT. It operates on the Akash Supercloud and supports various large language models (LLMs), with Llama 3.1 as the default model as of Aug 15, 2024. This setup provides users with a quick, free and privacy-focused chat experience without having to sign in. We asked AkashChat how it differs from its legendary Web 2.0 competitor, and below is what we received in response.
