Use a DAO to govern LLM training data, Part 2: The smart contract

In Part 1 of this series, we introduced the concept of using a decentralized autonomous organization (DAO) to govern the lifecycle of an AI model, specifically focusing on the ingestion of training data. In this post, we focus on the writing and deployment of the Ethereum smart contract that contains the outcome of the DAO decisions.

Use a DAO to govern LLM training data, Part 1: Retrieval Augmented Generation

Blockchain and generative AI are two technical fields that have received a lot of attention in the recent years. There is an emerging set of use cases that can benefit from these two technologies. In this four-part series, we build a solution that governs the training data ingestion process of an AI model, using a smart contract and serverless components. We guide you through the different steps to build the solution. In this post, we review the overall architecture of the solution, and set up a large language model (LLM) knowledge base.

How to deploy Stacks blockchain nodes on AWS with the AWS Blockchain Node Runners Stacks blueprint

Bitcoin is the most widely adopted and valuable cryptocurrency, known for its decentralization and security. Stacks, a Layer 2 solution built on top of Bitcoin, aims to unlock Bitcoin’s full potential by enabling fast, cheap, Bitcoin-secured transactions and smart contract functionality without modifying the Bitcoin protocol itself. Stacks uses a consensus mechanism called Proof of […]

Build secure multi-party computation (MPC) wallets using AWS Nitro Enclaves

Different types of blockchain applications and users demand varying types of private key management solutions, referred to as wallets. Custodial wallets are managed by third-party vendors such as a centralized crypto exchange, whereas non-custodial wallets give you full control and ownership over your private keys and funds. Crypto-native users with experience managing their own digital […]

How Agnostic Engineering improved storage latency for running Polygon nodes on AWS

This is a guest post co-written by Arnaud Briche, the Founder of Agnostic. At Agnostic, our mission is to democratize access to well-structured blockchain data. We aim to provide a swift, user-friendly, and robust method for querying the vast volumes of data generated by smart contract blockchains. As a company, for performance reasons we first […]

Run Polygon nodes on AWS

In this post, we dive deep into establishing your infrastructure and deploying Polygon blockchain nodes on AWS. We provide recommendations for selecting optimal compute and storage options tailored to various use cases. We discuss the approach to speed up the horizontal scaling of Polygon full nodes on AWS with Amazon Simple Storage Service (Amazon S3) […]

Build Account Abstraction Wallets with Alchemy and AWS: Part 2

In Part 1 of this series, we introduced the Account Abstraction (AA) concept and explained how it overcomes some of the user experience challenges of Externally Owned Account (EOA) wallets. We also covered how you can apply AA in the context of different use cases, such as marketing campaigns and enabling user onboarding at scale. […]

Make EOA private keys compatible with AWS KMS

Those who choose to take ownership of digital assets, such as cryptocurrency or non-fungible tokens (NFTs), are faced with a crucial decision when creating a wallet: do they opt to manage their own wallet or delegate that responsibility to a trusted third party? Non-custodial wallet solutions, whereby a user manages their own wallet, are popular […]

Build a web-based cryptocurrency wallet tracker with Amazon Managed Blockchain Access and Query

From startups like digital asset wallet providers to enterprises like banks, companies are launching digital asset products that provide end users the ability to buy, sell, exchange and monitor their digital assets, such as cryptocurrency. Whether the end user is an institutional investor or a retail investor / enthusiast, all of these digital asset products require […]

Import Ethereum private keys to AWS KMS

In the world of digital assets, private keys have always been of utmost importance. Unlike traditional assets, digital assets are controlled by private keys (a string of letters and numbers), just like passwords, which unlock the right to manage and use assets. Private keys can be used to irreversibly transfer funds from the wallet, thus, […]
