This primer on XCM, Polkadot's inter-chain messaging format is the first in a series of articles explaining what it does, how it works, how to use it, and what it could become.

By Bill Laboon, Director of Education and Community at Web3 Foundation Parachains are the diverse layer-1 blockchains that run in parallel on the Polkadot and Kusama networks. Parachains connect to Polkadot or Kusama by leasing a parachain slot on the Relay Chain. Apart from the slots for common good parachains, which are reserved for functionality that benefits the ecosystem as a whole, projects wishing to obtain a parachain slot need to participate in one or more parachain slot auctions. The

A look at why candle auctions are the most suitable form for blockchain auctions, as seen in recent research done at the Web3 Foundation.

Nominating and validator selection are crucial parts of user interaction with Polkadot. This post presents background information on nominating and things to consider when selecting validators.

With the increase in the number of accounts nominating on Polkadot and Kusama, we have seen some limitations of the current staking parameters. In order to prevent issues from occurring when these limits are reached, some restrictions are being added to the staking system on both networks.

The first Kusama parachain slot auction has ended and the first parachains have successfully connected to the Kusama Relay Chain, delivering the last piece of core functionality outlined in the Polkadot whitepaper: purpose-built, interoperable parachains.

On 24 May 2021, Polkadot nodes failed with an out of memory (OOM) error on block 5,202,216. This block contained an on-chain solution to the validator election, which is normally computed off-chain and only takes place on-chain if no off-chain solution is submitted.

The staged launch of Polkadot is about to reach another chapter. As we approach the launch of parachain functionality and the auctions and crowd-loans behind them, let’s look at what’s coming.

Despite being a tough year for pretty much everyone (with the possible exception of Amazon and takeaways), the Polkadot network and community is coming out of 2020 with the wind very much behind its sails. So now that we’ve reached the end of 2020, for better or worse, let’s have a roundup of what we achieved and what we’re planning to do over the course of 2021… I tend to start these roundups with a few statistics, and this year seems no exception. Development has continued apace, with the Rus

Polkadot es una red de blockchain que se escala extendiendo las transacciones a través de múltiples fragmentos de blockchains paralelas llamados parachains. Los parachains son fragmentos especializados de Polkadot que dan a los proyectos y a sus comunidades sobre sus respectivos objetivos. Siete equipos han añadido un parachain a la red de pruebas Rococo desde su lanzamiento el mes pasado, y varios otros en el ecosistema de Polkadot se mueven rápidamente hacia el mismo hito. Los espacios para

Kusama y Polkadot ahora premian a los curadores que ayudan a escalar las funciones de los consejos: ¡Únete a la fuerza que mueve a la comunidad hacia adelante!

Recently, changes occurred in relation to staking on Polkadot that caused some nominators not to receive their rewards. We are working on a permanent solution and suggest an immediate alternative here.
