Hyperchain SDK Glossary

A

Action

  • An operation that can be executed on any HyperSDK based Blockchain. In the Hyperchain SDK, actions implements the Action interface.

ActionRegistry

  • A registry that maps action typeIDs to their corresponding decoder functions. It's implemented using the TypeParser class in codec/typeParser.ts.

Address

  • A unique ID for an account on the any HyperSDK based Blockchain. In the Hyperchain SDK, addresses are derived from public keys.

Auth

  • An interface representing the authentication mechanism for transactions. It includes methods for verification and signature creation.

AuthFactory

  • An interface for creating Auth instances. It's responsible for signing messages and calculates the resource usage for the process.

B

BaseTx

  • The starting point for all transactions in the Hyperchain SDK and any HyperSDK based Blockchain. It includes the timestamp, chainID, and maximum fee for a transaction.

Block

  • A Block for Hyperchain's is a bundle of approved transactions plus a snapshot of the blockchain's current state. In HyperchainSDK, blocks are represented by the StatefulBlock class.

C

Codec

  • A utility tool for turning complex data into simple bytes and back again, making it easy to send and receive information across any HyperSDK based Blockchain with Hyperchains.

D

Dimension

  • An array of numbers representing different aspects of resource usage in our fee calculation. It typically includes bandwidth, compute, storage read, storage allocate, and storage write units.

F

Fee

  • The cost associated with including a transaction in a block. Fees are calculated based on the resource usage of the transaction's actions and authentication.

G

Genesis

  • A structure containing the initial configuration parameters for a HyperSDK blockchain, including various resource costs and limits used in fee estimation.

H

Hyperchain

  • A blockchain implementation built using Avalanche HyperSDK.

HyperSDK

  • An SDK for building custom blockchains by the Avalanche Team.

M

MessageBuffer

  • A utility class for managing message queues in our WebSocket communication.

R

Result

  • Shows us what happened when a transaction was processed, including success status, error messages, outputs, resource-usage, and fees.

RPC

  • A protocol used for making requests to a blockchain node. In the Hyperchain SDK, RPC calls are handled by the RpcService class in src/services/rpc.ts.

S

StatefulBlock

  • A representation of a block that includes state information.
