What is Polkadot?

Polkadot is a network protocol that allows arbitrary data—not just tokens—to be transferred across blockchains.

This means Polkadot is a true multi-chain application environment where things like cross-chain registries and cross-chain computations are possible.

Polkadot can transfer this data across public, open, permissionless blockchains as well as private, permissioned blockchains.

This makes it possible to build applications that get permissioned data from a private blockchain and use it on a public blockchain. For instance, a school's private, permissioned academic records chain could send a proof to a degree-verification smart contract on a public chain.

KEY FEATURES

Secure Validator Nodes: All of our nodes — from our public validator node to dedicated deployments — follow best practices to be responsible members of the network, keeping our nodes running and participating in network consensus.

Blockchain Package Manager (BPM) for Polkadot: BPM provides tools and packages to run blockchain nodes on your own infrastructure using a unified simple command line interface to deploy, maintain, monitor, and upgrade nodes. With BPM, teams can deploy blockchain nodes anywhere, enabling easy management - including scripting and automation. Find out more in the BPM QuickStart guide to get a sense of how it works, or dive right into the CLI docs.

Substrate API Sidecar Available: Any full node can be equipped with the API Sidecar, allowing users to fetch fully decoded blocks, get the balance of an address atomically (i.e. with a corresponding block number), get the chain's metadata, get a transaction fee prediction and information needed for auditing, and submit transactions to a node's transaction queue.

Monitoring, Alerting, and Automatic Healing: Blockdaemon Monitoring includes core machine-level metrics — CPU load, bandwidth, available disk space, memory — as well as blockchain specific metrics like peer counts, block height, transaction pools. Blockdaemon automatically monitors, repairs and replaces nodes where protocol-level errors may occur. When protocol updates are required, we make sure to apply them in advance so you see no disruption of service.

Dedicated Staff and Direct Access: Blockdaemon staff are active participants in the community. We’re dedicated to delivering the best performance, security, and developer experience, and we’re always here to help.
