Amazon Managed Blockchain FAQs

With AMB, you can more easily join public networks or create private networks across multiple AWS accounts with open-source frameworks, Hyperledger Fabric and Ethereum. These blockchain frameworks help network members securely transact and share data on a distributed and immutable ledger. Additionally, you can configure voting rules for your network so members can democratically govern it (like voting on who to invite to join).

To get started with AMB, go to the AWS Management Console and select Amazon Managed Blockchain. Then select "Create a network" or “Access a network.” Follow the network creation wizard to create your first network and member, and then invite other AWS accounts to join. Alternatively, follow the join network wizard to join a public network, and then provision nodes to interact with the network.

For step-by-step instructions, see Get Started Creating a Hyperledger Fabric Blockchain Network Using Amazon Managed Blockchain and Get Started with Ethereum in the Amazon Managed Blockchain documentation.

You can access AMB from the AWS Management Console, AWS Command Line Interface (AWS CLI), or AWS SDK.

Blockchain is a technology that makes it possible to build applications where multiple parties can record transactions without the need for a trusted central authority to ensure that transactions are verified and secure. Blockchain enables this by establishing a peer-to-peer network (a blockchain network) where each participant in the network has access to a shared ledger where the transactions are recorded. These transactions are, by design, immutable and independently verifiable.

Amazon QLDB is a ledger database purpose-built for customers who need to maintain a complete and verifiable history of data changes in an application that they own and manage in a centralized way. QLDB is not a blockchain. Instead, blockchain technologies focus on enabling multiple parties to transact and share data securely in a decentralized way—without a trusted, central authority. With AMB, customers can build on both public and private blockchains.

AMB Access offers two distinct types of blockchain infrastructure services: multi-tenant blockchain network access APIs and dedicated blockchain nodes and networks. With dedicated blockchain infrastructure, you can create and use public Ethereum blockchain nodes and private Hyperledger Fabric blockchain networks for your own use only. Multi-tenant, API-based offerings, however, such as AMB Access for Bitcoin, are composed of a fleet of Bitcoin nodes behind an API layer where the underlying blockchain node infrastructure is shared among various customers.
