What's inside Polkadot

  1. Overview of Polkadot validator offenses and punishments

    Polkadot employs mechanisms to disincentivize validator offenses through three primary punishments: slashing (loss of staked tokens), disabling (removal from the active set), and reputation changes. The severity of the punishment depends on the type of offense:

    OffenseSlash (%)On-chain DisablingOff-chain DisablingReputational Changes
    Backing Invalid100%Yes (High Priority)Yes (High Priority)No
    ForInvalid Vote2%Yes (Mid Priority)Yes (Mid Priority)No
    AgainstValid Vote0%Yes (Low Priority)Yes (Low Priority)No
    GRANDPA / BABE / BEEFY Equivocations0.01-100%Yes (Varying Priority)NoNo
    Seconded + Valid Equivocation-NoNoNo
    Double Seconded Equivocation-NoNoYes

  2. Overview of the DOT-KSM Trustless Bridge

    The Polkadot and Kusama networks use a trustless bridge enabled by GRANDPA consensus. This is achieved via Bridge Hubs: the Polkadot Bridge Hub runs a light client of the Kusama network, and the Kusama Bridge Hub runs a light client of the Polkadot network. This architecture allows Polkadot Asset Hub to bridge wrapped KSM tokens and Kusama Asset Hub to bridge wrapped DOT tokens, making both assets available across all parachains of both networks.

  3. Overview of Polkadot Vault cold storage

    Polkadot Vault (formerly Parity Signer) is an air-gapped cold storage solution that uses a smartphone in airplane mode as a key-chain tool. It allows users to create, manage, and restore accounts and securely sign extrinsics via QR codes without exposing private keys to the internet. It is not a full wallet and does not allow direct transfer of funds from the app itself. By default, it includes chain specifications for Polkadot, Kusama, and Westend.

  4. Overview of Polkadot Vault

    Polkadot Vault is a mobile application designed to replace Parity Signer. It transforms a spare mobile device into a cold-storage wallet for Polkadot accounts. Because it is a cold-storage manager, it requires a separate user interface (such as the Polkadot Developer Interface) to interact with accounts and issue transactions.

  5. Overview of Polkadot OpenGov governance

    Polkadot OpenGov is a stake-weighted governance mechanism where all proposals are initiated by the public. Changes to the protocol are agreed upon via referenda. The system uses 'tracks' associated with specific 'origins' to manage the flow of proposals. Each track has preset parameters determining the duration of a referendum and the maximum number of simultaneous referenda allowed. For example, treasury proposals are routed to different tracks (Small Tipper, Medium, or Big Spender) based on the amount of funds requested.

  6. Overview of the JAM Chain architecture

    JAM (Join-Accumulate Machine) is a prospective design to succeed the Polkadot relay chain. It functions as a domain-specific rollup chain that accepts computation outputs (rollups) from external sources and integrates them into a shared state. Unlike Substrate-based chains that require governance for adding pallets, JAM allows for the permissionless creation of 'services'—encapsulations of code, balance, and state similar to smart contracts.

  7. Overview of Polkadot Trustless Bridges

    Bridges enable cross-chain communication between Polkadot and external networks (e.g., Bitcoin, Ethereum). Polkadot favors 'trustless' bridge designs, meaning users rely on mathematics, code, and cryptography rather than centralized intermediaries or multi-signature relayers. A trustless bridge consists of both on-chain and off-chain components. On-chain components track finality and handle messaging, while off-chain components (relayers) transport data between the source and target chains.

  8. Overview of Polkadot Nomination Pools

    Nomination Pools allow users to pool tokens on-chain to nominate validators and receive rewards, improving staking scalability. Unlike custodial solutions, these pools are non-custodial, permissionless, transparent, and native to the Polkadot protocol. A key benefit is the lowered barrier to entry, allowing users to receive rewards for staking natively with as little as 1 DOT.

  9. Overview of Agile Coretime

    Agile Coretime is Polkadot's scheduling system that allows for the efficient utilization of network resources. Unlike Polkadot 1.0, which required long-term leases and significant DOT locking, Agile Coretime enables multi-threading by splitting and interlacing coretime. It allows builders to purchase coretime in bulk or on-demand, reducing barriers to entry and improving resource allocation efficiency.

  10. Overview of Polkadot Proxy Accounts

    Proxies allow a user to delegate limited actions to another account (the proxy) on behalf of a primary account (the proxied account). This enables the primary account to remain in cold storage or a hot wallet while still actively participating in the network using the weight of its tokens. Proxies can only perform actions related to specific substrate pallets as defined in the network runtime.

  11. Overview of the JAM computational model

    JAM (Join Accumulate Machine) is a research and development project by Parity Technologies. It is a computational model designed to collect, refine, join, and accumulate data within a blockchain network. Its primary goal is to provide a flexible and efficient framework for managing data and computations, offering scalability similar to rollups but at the consensus layer. This allows developers to build both smart contracts and appchains within a single, rich environment without needing separate rollup solutions.

  12. Overview of Polkadot 2.0 Technical Upgrades

    Polkadot 2.0 transforms the network into a multi-core decentralized computer providing resilient and verifiable computation via virtual cores. It introduces three major technical upgrades to improve throughput, efficiency, and accessibility:

    1. Asynchronous Backing: Enables pipelining to increase rollup throughput without compromising security.
    2. Coretime: Allows for the agile allocation of cores for execution on the decentralized computer.
    3. Elastic Scaling: Enables a single rollup chain to use multiple cores simultaneously to boost throughput.
