After more than a decade of overcoming the odds, blockchain has won its place in society thanks to the possibilities it provides. Everywhere you look, it seems like there are people finally coming around to the tangible capabilities of cryptocurrency. This is especially true in the realm of business where companies understand that they must constantly innovate if they want to remain competitive in the current marketplace. 

Ultimately, the challenge may be to find a blockchain that can handle an excessive amount of traffic and maintain the continuous development needed to support every evolving use case. In theory, this is a tall order. In practice, it seems next to impossible based on the limitations we have already experienced from blockchain in its current form. In all likelihood, numerous different blockchains will have to work together, all contributing their singular advantages to form a larger, collective whole. But with so many different networks, protocols, and developers, how can true unity be possible? 

Polkadot has emerged as one potential master key to unlocking the true power of a united blockchain system. Their most meaningful ambition is to weave all of these individual chains together so that any service or application can be accessed from anywhere on the network. Polkadot has quickly become one of the top cryptocurrencies by market capitalization and garnered massive support from the crypto community. 

The history of Polkadot 

Polkadot has a regal lineage as a product of Dr. Gavin Wood. As one of the original co-founders of Ethereum, Wood has been around the cryptocurrency space for years and is also credited as the creator of the Solidity smart contract language. In late 2016, Wood completed the first version of the Polkadot white paper, bringing the fully-fleshed-out idea into the world. 

The following year, Wood founded the Switzerland-based Web3 Foundation alongside Peter Czaban. This foundation launched Polkadot’s first token sale as a Dutch auction, raising $145 million from the sale of five million DOT tokens in two weeks. After this fundraising event, Parity Technologies, another company Wood founded, began the development of Polkadot. 

After a series of different efforts demonstrating proof that the concept was functional, including full trials on different testnets, the Polkadot mainnet launched on May 26, 2020. Since then, the team has been steadily building and adding new upgrades and developments. Meanwhile, the DOT token has gained fans worldwide while enjoying continuous listings across the biggest crypto exchanges. 

Polkadot’s core use case

Polkadot has an ambitious goal in mind: interoperability. For blockchain technology to truly spread to every corner of the world, each network will eventually be forced to intermingle. The protocol that Polkadot has implemented allows unique blockchains to securely talk to one another, even though their underlying tech may be at odds. This enables a flow of data across chains to facilitate a wide range of applications.

The challenges that this industry faces are staggering. Beyond the regulators, beyond the naysayers and doubters, and even beyond the financing, the biggest roadblock to mass adoption has proven to be scalability. The limitations that Ethereum and Bitcoin have experienced during times of peak use have been debilitating. For instance, it seems as though it takes just one killer app or highly-anticipated NFT to slow the Ethereum network to a crawl.

Where some scaling solutions may act as an intersecting highway to alleviate a large portion of the traffic, Polkadot can be visualized as a roundabout. All the data from different blockchains reaches one central loop, all flowing together before it finally exits in the direction it needs to go. It is both efficient and scalable, and it achieves this through the use of many parallel chains, or “parachains.”

DOT protocol architecture 

Polkadot’s architecture has been called one of the most innovative in the cryptocurrency space. Thus far, overcrowded networks like Ethereum and others delegate some of their traffic to Layer 2 (L2) solutions. These L2 networks are protocols that run on top of an existing blockchain. Users have accepted these options with open arms, and as a result, much of the value from Ethereum transactions have been siphoned away to alternatives like Polygon and Loopring. 

Instead, Polkadot considers itself to be something more akin to a Layer 0 solution. Instead of running as an individual network on top of Ethereum or Bitcoin, Layer 0 solutions connect blockchains at the base level, directing so-called “parachains” (individual blockchains) to one center relay chain that is a gateway for the data. In this sense, you can think of the relay chain as a bicycle wheel hub, with the connected parachains being the spokes of the wheel. 

Nominated proof of stake (NPoS)

Polkadot also employs a variant of proof of stake called nominated proof of stake (NPoS). This was decided on with certain principles in mind, namely fair representation, increased security, and decentralization. This staking system allows users to contribute directly to the network by becoming either a validator or a nominator. 

Nominators vote their approval of validator candidates and then back them with their tokens. Next in the process, a committee of appointed validators will elect new validators from the pool of selected candidates. There are heavy economic incentives involved, as well as certain risks. 

Since validators and nominators lock up their tokens to receive rewards, there must be a measure of trust between these parties. Validators could potentially become negligent by going offline or even attacking the network. Because this puts everyone’s rewards at risk for slashing, meaning that validators will be forced to relinquish a portion of their stake, these actions are discouraged by the protocol. 

How does Polkadot achieve interoperability?

To achieve interoperability, Polkadot implements the use of blockchain bridges. These bridges allow for arbitrary data to seamlessly transfer from one chain to another. Because it is simple data that is being delivered, and the associated blockchains do not conflict with one another, a large number of protocols, governance, and rules can coexist in harmony. 

All data that is passed between networks is enabled with XCM, a cross-consensus messaging format. Developers have been adamant that this is not a protocol, meaning that it does not send messages by itself. XCM only indicates the sending and receiving format for connected chains.
