What is Polkadot (DOT)? Everything to Know About the Polkadot Blockchain
In the ever-growing landscape of cryptocurrencies and blockchains, Polkadot has emerged as a viable investment opportunity. Polkadot (DOT) can be bought, sold, or traded on a litany of major cryptocurrency exchanges, but its core technology – built on parachains – is what helps it stand out.
In the guide below, you will learn all that there is to know about Polkadot, its native DOT token, what makes Polkadot a unique entity, Polkadot price prediction, and more. The Polkadot protocol is different from traditional blockchains in that it acts as the intermediary between a number of major chains like Bitcoin and Ethereum without having to use an intermediary. Keep reading to find out what Polkadot is all about.
What is Polkadot (DOT)?
At its core, Polkadot is a multi-chain network. It allows for scalability and interoperability between various blockchains, including both the Bitcoin and Ethereum blockchain networks. Polkadot was created to address issues facing earlier blockchains, making it possible to share information and communicate between different blockchains.
Within the Polkadot platform is the native DOT token. The token serves two main functions on Polkadot’s network. First, it is a governance token that allows holders to have a vote and say in the network’s protocol. Secondly, it is used for staking purposes, which is crucial for verifying transactions on the Polkadot network.
Who are the Founders of Polkdot?
Polkadot is the creation of Gavin Wood, who also co-founded the Ethereum network. He partnered with Peter Czaban and Robert Habermeier, with Wood publishing a white paper for Polkadot in 2016. The core technological components behind Polkadot were created and developed by Parity Technologies.
With its initial coin offering, $144.3 million was raised by the project in 2017. Major developments came in May 2020 with the launch of the Polkadot mainnet using a proof-of-authority protocol. The network has since transitioned to the NPoS mechanism, which allows token holders to nominate their own validators to process transactions and secure the Polkadot network.
What Makes Polkadot (DOT) Unique?
Polkadot is unique for a number of reasons. With a deeper dive, we can see why Polkadot works as a blockchain intermediary, offering benefits like unique governance, flexibility, adaptability, interoperability, scalability, and more.
The Relay Chain and Parachains
One of the focal points of the Polkadot blockchain is parachains. These are blockchains that are capable of running independently and can be completely customized by its owner. Parachains can host virtually any kind of application, plus they have programming logic and features that have no limitations.
The Relay Chain is what binds everything together. It is the central point connecting parachains to other major blockchain networks. The Relay Chain is responsible for things like consensus, interoperability, and overall network security. The Relay Chain is responsible for validating data and ensuring that it is understandable when it comes to achieving consensus and making sure that transactions are properly executed.
Bridges, on-Demand Parachains, and Substrate
Another unique aspect of Polkadot is that it uses bridges. These bridges connect blockchains, allowing data to flow freely between them. Those bridges are what make interoperability possible, capable of connecting major blockchains like Ethereum and Bitcoin.
There are also on-demand parachains, which basically work in the same manner but are smaller in scale and work on demand. On-demand slots can be quite useful when it comes to blockchains that don’t need continuous connectivity to Polkadot’s network.
Finally, there is Substrate. This is a blockchain development framework created by Polkadot’s parent company, Parity. Substrate is vital to the project because it allows developers to create their own blockchains within the Polkadot network. It gives individuals, teams, and companies the chance to build on a parachain. The framework handles virtually all of the legwork required to create a blockchain, making the process much faster and more efficient.
Flexibility and Adaptability
One of the factors driving change within many major blockchains is the ability to be adaptable. Scalability and interoperability tie into these things, and the Polkadot blockchain already has a leg up on major blockchains because it was built to be both flexible and adaptable.
The structure of the Polkadot blockchain makes it much easer to deploy custom chains, known as parachains. These can be used for Polkadot’s Substrate framework, which allows for rapid development and greater flexibility, giving Polkadot an edge in one of the most critical aspects of the blockchain market.
Governance
Holders of the native DOT token not only gain monetary value from holding the token but actually get to participate in the overall governance of the network as well. That’s because DOT token holders get a vote in certain governance mechanisms.
DOT holders can vote on things like network upgrades, proposals, and more. Through the Nominated Proof-of-Stake (NPoS) protocol, holders can even become validators if they meet specific qualifications along the way. Polkadot allows users to have a much more hands-on involvement than larger blockchains like Bitcoin.
Interoperability and Scalability
The core function of Polkadot is to give other blockchains the ability to interact with one another. Through these connections, blockchains can share data and other resources. Traditional blockchains like Bitcoin and Ethereum do not have these functions on their own, so Polkadot comes in handy.
Scalability is one of the biggest challenges facing existing blockchain technology. Though new software updates are coming to help Bitcoin, Ethereum, and others handle those issues, Polkadot is useful in that it allows multiple chains to work in tandem, increasing overall efficiency and throughput.
How Many Polkadot (DOT) Coins are There in Circulation?
Polkadot (DOT) has a maximum supply of 1.52 billion DOT. The entire maximum supply has been released into circulation, meaning that there are 1.52 billion DOT currently circulating. Because of that, Polkadot (DOT) has the same market cap and fully diluted valuation.
How is the Polkadot Network Secured?
Polkadot and its interoperability come as the result of common validators. These validators work to secure the various blockchains, allowing them to scale transactions by spreading out the data required across a number of parachains within the Polkadot network.
The Polkadot network uses a Nominated Proof-of-Stake (NPoS) mechanism. This consensus mechanism works by selecting validators and nominators, allowing chains to interact with one another securely while following the same rules, though each chain has its own independent governance.
Polkadot (DOT) Ecosystem
The Polkadot ecosystem is anchored by a main chain known as the Relay Chain. This chain is what coordinates and secures the entire network. It is responsible for handling network-wide operations, providing consensus, and providing validity for transactions on the network.
Multiple transactions can be handled in parallel, improving the overall scalability of Polkadot compared to more traditional blockchain networks. Polkadot is capable of handling crowd loans, parachain auctions, independent token economies, bridge parachains, smart contract parachains, and a litany of other functions.
