A Guide to Polkadot & Kusama Parachains
Parachains are custom, project-specific blockchains that are integrated within the Polkadot (DOT) and Kusama (KSM) networks.
Parachains can be customized for any number of use cases and feed into the main blockchain, called the Relay Chain, considered to be the heart of the Polkadot and Kusama networks.
The Relay Chain is responsible for the network’s shared security, consensus and transaction settlements, and thus, by being integrated into the Relay Chain, all parachains benefit from the Relay Chain’s base features.
Entre otras cosas, esta estructura de diseño puede ayudar usuarios de Parachain a realizar transacciones más rápidamente a menores costos y a los desarrolladores de Parachains les permitirá crear blockchains que no revelen a la red pública información de los usuarios o que no tengan que procesar un alto número de transacciones.
Los Parachains optimizan su funcionalidad para casos de uso específicos y en muchos casos soportan sus propios tokens. Para convertirse en un Parachain en Polkadot y Kusama, los proyectos deben participar en una subasta de Parachain.
Ejemplos de proyectos que esperan participar en subastas y asegurar un slot Parachain incluyen Moonriver, un entorno blockchain para Kusama compatible con Ethereum, y Karura (KAR), una hub de finanzas descentralizada (DeFi) que va a permitir a los usuarios ganar rendimiento en su cripto y actúa como una infraestructura facilitadora de crédito para Kusama.
Cómo funcionan los Parachains
Polkadot and Kusama are networks that allow both information and tokens to be transferred on them. Unlike Ethereum, where decentralized applications are created within the bounds set by its blockchain, Polkadot and Kusama allow developers to create their own independent blockchains.
This means that each parachain can have its own parameters such as block times, transaction fees, governance mechanism and mining rewards.
Parachains benefit from the Polkadot and Kusama network’s security, maintained by the Relay Chain, rather than having to rely on their own set of validator nodes. Instead, parachains are maintained by collator nodes that store a full history for each parachain and aggregate parachain transaction data into blocks to be added to the Relay Chain.
Polkadot and Kusama are expected to only support up to 100 parachains slots on their networks, a number that is flexible and subject to change.
Each parachain has a dedicated parachain slot to attach to the Relay Chain, and, in order to gain access to one of the slots, Web3, the team behind Polkadot and Kusama, has created what they call Parachain Auctions as a method to distribute the available slots in an equitable manner.
Parachain auction participants have a determined amount of time to place bids on the projects they wish to see get a parachain slot, and the project that garnered the most support at a randomly determined time during the bidding process will generally obtain the ability to use a parachain slot.
