How to take part in parachain auctions with crowdloans

 


With its parachains, the Polkadot ecosystem stands for interoperability like no other blockchain. The rush is great: only selected projects get a limited parachain place. We show how you can participate in the auctions with crowdloans and why participation can be worthwhile.


Demographic change does not stop at blockchain technology either. The Bitccoin blockchain paved the way for publicly shared and decentrally managed ledgers and thus for anonymous transactions - Ethereum has enriched the crypto ecosystem with decentralized applications with the introduction of smart contracts. After the first and second generation, it is projects like Cardano, Solana and Avalanche that usher in the third blockchain generation with a focus on interoperability and scalability. Polkadot is also part of the new generation.


Launched by former Ethereum co-founder Gavin Wood in 2016 and managed by the Web3 Foundation , Polkadot aims to ensure cross-chain communication in the crypto landscape. Blockchains are closed systems, and the exchange of data between networks via oracles and bridges is resource-intensive and prone to errors. Polkadot found an answer to these problems: parachains.


What are parachains in polkadot?

Parachains are stand-alone blockchains that are attached to the Polkadot relay chain and are thus embedded in the cross-platform ecosystem. The relay chain is the heart of Polkadot, it ensures security, ensures consensus-building and manages the status of the connected networks. As a parachain at Polkadot, blockchains benefit from high user activity and liquidity, but act confidently. They have their own native currencies and specific uses.



While many blockchain networks have specialized in certain use cases, Polkadot can cover the entire spectrum with the Parachain system: from decentralized finance (DeFi), gaming and supply chains, to oracles to the Internet of Things (IoT). Polkadot is as multifaceted as its parachains.


The advantage: The exchange of data between the networks is extremely permeable - also between private and public blockchains. In this way, data from public networks can also be used for applications on public blockchains, and vice versa. In addition, transactions can be processed in parallel, which ensures high throughput.


While smart contracts are often limited to transactions, Polkadot allows all data to be exchanged and processed. Ultimately, behind Polkadot is the vision of an Internet of Blockchains that enables cross-platform interactions, breaks up the monopolies of big techs and gives users back control over their data. Thus, Polkadot's declared goal is to build the Web 3.0.


Parachain auctions

Whether a blockchain can even attach itself to the relay chain depends on whether it receives enough support from the community. Parachain places are up for auction, since the capacity is limited to a maximum of 100 chains, the rush of candidates is correspondingly large.


The application process for a parachain place works via so-called candle auctions. The projects with the highest grants are awarded the contract. If the participation is successful, a certain amount will be deposited and blocked in DOT for the Parachain term. That is usually 24 months. After that, the donors will get their borrowed money back.


The DeFi platform Acala won the first Parachain auction in November 2021 with DOT worth over 1.3 billion US dollars. There are currently six parachains on Polkadot, Kusama, the testnet also operated by the Web 3 Foundation and on the same code base as Polkadot, now comprises 22 parachains.


Crowdloans

In order to raise funds for a project and thus also give smaller, but all the more ambitious projects access to the Polkadot ecosystem, crowdloans were introduced - loans that provide projects with capital and, in return, enable participants to generate lucrative returns.


Crowdloan campaigns can start even before the auction slots open. The projects set an upper limit. If this is reached, the campaign ends automatically. The funds will be paid back after the end of the parachain period or if the campaign fails.


The projects are free to decide what remuneration users receive for their financial injections. "It is up to the individual Parachain teams to decide whether and how they want to reward participants who forego stakes and choose to block their tokens in support of the Parachain campaign," explains the Web 3 Foundation.


The range is correspondingly colorful. As a rule, users receive a certain amount of the native currencies of the respective blockchain networks. How high these turn out to be and the times at which payments are made varies. NFT giveaways and raffles are also not uncommon. For example, the Darwinia Network split a Bitcoin among the top five bidders.


So you are there

In order to be able to participate in Parachain auctions via Crowldoans, you only need two things: a Polkadot wallet and some start-up capital in DOT. The “Polkadot JS Extension” browser wallet can be installed free of charge in Firefox or Chrome, then also via the Brave Browser. At polkadot.js.org/apps you can find a list of all currently running and already completed Parachain auctions as well as information on profit sharing. Simply select a project, participate under “Contribute” and you're done.



Important: The minimum amount for each Parachain auction is five DOT. At the time of going to press, that's the equivalent of $ 117. And even more important: the wallet should contain at least one DOT after the transaction is complete. Any amount below that will be destroyed. Including transaction fees of around 0.02 DOT, 1.1 DOT should be planned in addition to the 5 DOT.

The 5 largest platforms for non-fungible token (NFT) collectibles

  Since the beginning of 2021, non-fungible tokens (NFT) have had no holding back and the sector is setting new records almost every day.  More and more artists, stars and brands are realizing the potential - NFT are well on their way to catapulting the crypto space into the mainstream.  But which collectibles are currently the most popular? What are NFT? NFT are unique tokens that cannot be exchanged one-for-one for an equivalent token.  Any asset that is tokenizable can be an NFT.  This includes, for example, (digital) works of art, trading cards, game items and crypto domains.  Theoretically, however, real estate or securities can also be mapped as NFT. NFTs can be used to transparently map ownership structures on a public blockchain.  This allows them to store value just like real objects, even if additional copies are easy to make.  For example, the original picture of the Mona Lisa is significantly more valuable than a photo, as everyone kno...

CARDALONIA: THE CARDANO METAVERSE OPENS THE GATES!

  Have you ever been to Cardalonia? With these words, the Cardano Metaverse called Cardalonia starts the gates. In this 3D world, developers and users can interact with each other. First of all, users have to create an individual character with which they can move online. After that you can enter one of the worlds built by developers with this character. You can also purchase your own land in the Cardano Metaverse via the marketplaces in Cardalonia . This is secured by Cardano's blockchain technology and therefore offers a relatively secure transfer of ownership. Since these are only digital plots of land, it is not yet entirely clear when the plots of land are purchased whether they can also be sold again in the future. A possible profit cannot be estimated at the moment. In Cardalonia, the cryptocurrency Lonia is used. The maximum amount of tokens in circulation is 100,000,000. The team consists of Alice Sand (Co-Founder), Vasil Air (CTO) and Dustan Water (Fullstack Developer). T...

Cardano: This is the vision that founder Charles Hoskinson has

  The Altcoin Cardano has tended to decline in recent weeks.  The Alonzo upgrade was supposed to bring improvements, but it soon turned out to be a disappointment.  Cardano founder Charles Hoskinson presented his vision for the cyber motto in a live Twitter video. • Cardano in the last few months under pressure • Charles Hoskinson explains his Cardano vision via Twitter • Security and privacy at the center The cryptocurrency  Cardano  has had a difficult few months.  While founder Charles Hoskinson's cyber motto has had a strong run in 2021, it has been steadily downhill in recent months.  Cardano is faced with some difficulties.  The so-called Alonzo upgrade went live in mid-September, for which crypto fans had high hopes, but which soon turned out to be a disappointment.  The upgrade should make it possible to use smart contracts on the cryptocurrency as well.  It soon turned out, however, that although these were entered into Cardano,...
