What is a Polkadot (DOT) Coin?
Polkadot is a sharded ecosystem at its core. It helps blockchains intercommunicate by bringing them to one secure network. The network accomplishes this task with three main elements, the relay chain, parachains, and parathreads.
A parachain is a separate entity connected to Polkadot’s network. It benefits from shared security and ease of messaging from the main relay chain. Chains have their native tokens and maintain their own blocks.
Support for up to 100 parachains is anticipated, making slots limited. Auctions and governance decide on slot distribution.
The auction process requires projects to bond or lock up DOT tokens, making them unavailable for other uses. Teams can even raise DOT from holders through a crowdloan module. It’s expected new parachains will reward DOT holders who contribute to the reserves with their platform’s native tokens.
Parathreads unlock the same features as parachains. The only distinction is that they adopt a pay-as-you-go model, rather than having dedicated leased slots. Multiple parathreads may share resources, with parachains having dedicated resources, a similar concept to shared versus dedicated hosting.
The Polkadot (DOT) coin is the blockchain’s native utility token. It has three main uses. DOT holders decide on administration issues such as voting on charges, auction matters, upgrades, and new parachain schedules. During bonding, DoT tokens are used as a form of Proof-of-Stake. New parachains hold slots for a limited time before their lease runs out.
When parachains depart, the bonded tokens are likewise removed. While Polkdot runs on Proof-of-Authority during its launch, users will have the ability to stake DoT tokens to facilitate the platform’s consensus mechanism.
Who founded Polkadot?
The official website attributes the founding to three people, Robert Habermeir, Gavin Wood, and Peter Czaban. It debuted online in May 2020 as the flagship project of the Web3 Foundation, where Gavin serves as the President and Peter as its technology director. The foundation funds team is creating cutting-edge applications for the future internet.
Gavin famously left Ethereum after realizing that they were not doing enough to realize a truly decentralized vision. He went on to invent the Proof-of-Authority concept and proposed Solidity, a high-level programming language for smart contracts.
What is special about Polkadot technology?
Polkadot technology is unique in that it solves the problem of interoperability where distinct blockchains can intercommunicate or share resources seamlessly. Its true value is the ability to connect private, permissioned, and public blockchains.
This presents a world of opportunities. Think of an insurance company blockchain requesting verification of a driving license from a smart contract on a public chain. Not only can parathreads and parachains interpolate, but they can also leverage bridges for external communications.
Another major advantage of Polkadot is helping blockchains pool expensive network resources. Polkadot’s security applies to all connected chains. Using Proof-of-stake similarly allows the platform to remain energy efficient and lessen energy waste.
So, overall, Polkadot’s power lies in its potential ability to chain up parachains to create unique economies and platforms. It can bring on board some of the largest blockchains.
How many DOT coins have been issued?
The total issuance of DOT tokens was 1170844254.33 DOT and the percentage of staked coins was 52% as of March 17th, 2022. The coin doesn’t have a maximum supply, and inflation is built into the coin at 10% per annum. View the dot Polkadot price from our chart (see above).
How is a Polkadot network secured?
Polkadot plans to leverage the Proof of Authority consensus proposed by Gavid before the network runs smoothly. Six validators from the Web3 foundation maintain the chain. Afterward, the team will implement decentralized validators and NPoS. DOT holders stake or risk their tokens when nominating validators and in turn, earn rewards.
Why is it worth investing in Polkadot?
Polkadot may be a worthwhile investment considering the uniqueness and practicability of its technology. It promises to make chains truly decentralized by reducing their reliance on private implementations.
The price of Polka Dot coin may see more action with the addition of new parachains and competitive auctions. DOT holders are also uniquely suited to earning coins from other parachains by offering them for crowdloans for chains raising enough DOT for bonding and acquiring leases. The true potential of the network only remains to be seen and could prove quite valuable once real-life interactions are enabled.
