Try Flow on Blockdaemon Blockdaemon provides full end-to-end node management and support for Flow, a fast, decentralized, and developer-friendly blockchain, designed as the foundation for a new generation of games, apps, and the digital assets that power them.

Why Use Blockdaemon? Blockdaemon is the Total Node Management Solution

Blockdaemon guarantees peace of mind, as you never have to worry about maintaining or upgrading your nodes ever again — we look after all of that for you. Our finger is constantly on the pulse of each blockchain we support to ensure all of our nodes remain perfectly healthy. Our extensive experience across protocols lets us expertly monitor, repair and replace nodes where protocol level errors may occur. For any protocol updates needed, we look after these in advance so you never see any disruption in service.

Enterprise Level Security

Security is our top priority here at Blockdaemon. All nodes purchased through us are 100% customer dedicated. This means your node is yours exclusively. You’ll enjoy a dedicated node which has a unique address, its own unique connection and authentication key. Furthermore, these are never reused. We ensure your node is not open and exposed to anyone on the internet. Any nodes you’d like to add on additionally can be done so quickly and easily as well!

A Trusted Partner

Blockdaemon is by your side on your blockchain journey. We are the only infrastructure platform for blockchain nodes which offer multi-cloud and multi-geographical support, with just a few clicks. Want custom configurations and branded experiences? No problem, we provide a unified, whole-org, collaborative rollout to manage a complete network. Whatever your needs, we will work closely with you to deliver the solution you need.

Flow Key Features

Multi-node architecture

Flow’s design is unique, allowing the network to scale to serve billions of users without sharding or reducing decentralization of consensus. Flow achieves this by applying pipelining to blockchains by separating the jobs of a validator node into four different roles: Collection, Consensus, Execution, and Verification. This separation of labor between nodes is vertical (across the different validation stages for each transaction) rather than horizontal (across different transactions, as with sharding).

Developer Friendly

Flow uses Cadence, the first ergonomic, resource-oriented smart contract programming language. This language has a comfortable, ergonomic syntax making it very easy to read. It uses a strong, static type system to minimize runtime errors, and allows all methods, interfaces, and transactions to include pre- and post-conditions to enforce expected behaviour. This has resulted in a language that is easier to learn and significantly easier to audit.

Consumer Friendly Onboarding

A key feature of Flow is being consumer friendly, aimed at mainstream adoption. Human readable security is a core component here, as the Flow transaction format makes very strong guarantees about what kinds of changes a transaction can and can not make. This makes it easy for the wallet to ensure users are making informed decisions about what they are approving. Also included is added security through optional multiple signature support, with the ability to cycle out old keys regularly to avoid security leaks.

Secure Validator Nodes

All of our nodes — from our public validator node to dedicated deployments — follow best practices to be responsible members of the Flow network, keeping our nodes running and participating in network consensus. Validators on Flow can get started as Consensus or Verification Nodes.

Frequently Asked Questions

  • What is the role of the different nodes in Flow?

    The nodes in Flow all play different roles. 

    • Consensus Nodes decide the presence and order of transactions on the blockchain
    • Verification Nodes are responsible for keeping the Execution Nodes in check
    • Execution Nodes perform the computation associated with each transaction
    • Collection Nodes enhance network connectivity and data availability for dapps

    Consensus and Verification Nodes together are the foundation of security in the Flow network and leverage crypto economic incentives to hold the rest of the network accountable.

  • How are rewards distributed to node operators in Flow?

    Validator node operators supporting the network receive a portion of the transaction fees that pass through the system proportional with the work they do and their associated stake. Unlike miners or validators for other blockchains, validators on Flow can get started as Consensus or Verification Nodes with relatively cheap hardware, ensuring broad, equitable participation and decentralization. In the early years of the network when fees are low, the network will provide additional rewards to node operators proportional with their efforts and associated stake.

  • How fast does Flow achieve finality?

    Finality refers to the point at which a blockchain user can be confident their transaction is permanently included in the chain. On Flow, deterministic finality is achieved within seconds: once Consensus Nodes determine which block a transaction will be a part of, user agents can in most cases execute the transaction locally and give feedback to the user almost immediately.
