Polkadot, an open-source multichain protocol that facilitates cross-chain transfer through a network of specialized blockchains, has grown notably since its inception.

The sharded multichain network stands out due to its high scalability, capable of processing many transactions on parallel chains called parachains.

While it boasts several Web3 applications built on its protocol, the Polkadot team is actively exploring improvement updates to enhance and expand its network.

This brings us to Polkadot 2.0, an upcoming version of Polkadot expected to introduce several enhancements to the network. 

What is Polkadot 2.0?

Polkadot founder Gavin Wood announced Polkadot 2.0 in June 2023. It represents a significant evolution for the Polkadot network, which has experienced substantial growth over the years due to its distinctive features. 

This latest version, tagged Polkadot 2.0, introduces a fundamental shift in allocating network resources.

It simplifies how developers utilize the network for their projects, particularly those transiting from Web2 to Web3. This new model could attract more projects to the Polkadot ecosystem. 

One notable modification in Polkadot 2.0 is in block distribution. Currently, the network employs a fixed lease model, but the upcoming system will allow developers to purchase blockspace as needed, whether in bulk or on demand. 

Features of Polkadot 2.0

Polkadot 2.0 is a next-generation blockchain protocol that addresses the limitations of existing blockchains, such as scalability, interoperability, and security. It relies on a new architecture that allows different blockchains (known as parachains) to connect and communicate with each other. 

This allows for a more scalable and interoperable blockchain ecosystem where users can seamlessly transfer assets and data between blockchains. Polkadot 2.0 also includes several other features that make it more secure and efficient than existing blockchains.

These features include a new staking system, an on-chain treasury, and a governance system that allows users to vote on changes to the network.

By addressing the limitations of existing blockchains, Polkadot 2.0 can make blockchain technology more accessible and valuable for a broader range of applications.

Polkadot 2.0’s main idea focuses on introducing elastic cores that can adapt to changing computational requirements. Currently, parachains in the Polkadot network operate like fixed CPU cores in a supercomputer.

However, the upcoming system aims to allocate resources more flexibly, adjusting in real time to meet the network’s security needs. This innovation can significantly improve overall efficiency in the DOT ecosystem.

Another notable change in Polkadot 2.0 relates to how core time, which represents the time required for validation and consensus on the Polkadot Relay Chain, is allocated.

With the new version, users can purchase more time as block time through an auction system and a pay-as-you-go model with a fixed price.

Polkadot 2.0 Will Cater to Developers’ Dynamic Needs

According to Wood, the new system’s design will be responsive to the changing demands of developers to prevent potential design challenges in the future. He also pointed out that this fresh system could enhance the liquidity of DOT tokens by reducing the duration of token lockup.

The introduction of this novel model represents a significant milestone in the evolution of Polkadot, a departure from the current parachains model, where block space allocation predominantly relies on an auction mechanism and fixed lease periods. 

The upcoming system is anticipated to increase the accessibility and affordability of Polkadot for developers, thus encouraging innovation within the Web3 ecosystem. Polkadot 2.0 is still under development, but it has the potential to revolutionize the blockchain industry.

Components of the Polkadot network

Polkadot is a versatile and innovative blockchain network that introduces several key components to facilitate a robust and interconnected ecosystem. Its design emphasizes interoperability, scalability, and security.

The main components of the Polkadot network are as follows:

Relay Chain

Polkadot’s central component is the Relay Chain, which is responsible for network security and consensus. It employs a hybrid consensus mechanism known as Nominated Proof-of-Stake (NPoS). 

The Relay Chain connects and coordinates the activities of various parachains and maintains the overall network security. It secures the shared security model that makes Polkadot unique, ensuring that each parachain benefits from the collective security of the network.

Parachains 

Parachains are individual blockchains connected to the Relay Chain. These parallel chains (parachains) support various use cases and are customizable for specific applications like DeFi, gaming, or supply chain management. 

Parachains enable developers to build their blockchains with their governance and token systems. For example, let’s consider a parachain designed for a decentralized exchange.

This particular parachain can be specifically configured to handle a large number of transactions with high efficiency. 

Additionally, some parachains, like the Astar Network, have advanced features such as compatibility with the Ethereum Virtual Machine (EVM). They also come with the ability to execute WebAssembly (WASM) smart contracts and support cross-consensus messaging (XCM).

These features are crucial for promoting smooth communication between decentralized applications (DApps) and enabling interoperability within the Polkadot ecosystem.

The parachain slot auction system determines which chains are connected to the Relay Chain, providing a scalable and dynamic environment.

Bridges

Bridges in Polkadot facilitate interoperability with other blockchains, such as Ethereum. They enable assets and data to move seamlessly between Polkadot and other networks. This connectivity is crucial for the exchange of tokens. 

Imagine a developer needing data from two incompatible blockchains for a single application. Such development tasks would only be feasible with a bridge system. Bridges bypass the incompatibility, ensuring the two chains can communicate effectively.

In this context, Polkadot acts as a facilitator, enabling the exchange of information and fostering effective communication between these two disparate blockchains. This will allow Polkadot to tap into the broader blockchain ecosystem and leverage the capabilities of other networks.

Nominated Proof-of-Stake (NPoS)

NPoS is Polkadot’s consensus mechanism, which ensures network security and efficiency. Token holders in Polkadot can nominate validators who participate in block production and finalization.

This system promotes decentralization and network security while allowing DOT holders to participate actively in the network’s governance.

Validators

Validators are essential to network participants in Polkadot. They produce blocks, validate transactions, and maintain the network’s security. 

To become a validator, one must lock up a significant amount of DOT tokens as collateral. DOT token holders elect validators whose performance is vital to achieving consensus on the Relay Chain.

Collators

Collators assist parachains by collecting and proposing transactions to be included in the parachain blocks. They play a critical role in the efficiency of parachains, helping to aggregate transactions and maintain the chain’s functionality.

Another distinctive feature of the Polkadot network is its role as a layer-0 blockchain. In this capacity, the network becomes the fundamental framework for building subsequent blockchains.

Being a layer-zero blockchain, Polkadot offers the infrastructure necessary for developers to create their blockchains while ensuring seamless cross-chain interoperability.

In other words, blockchains built on the Polkadot platform can effortlessly communicate and interact with each other, regardless of their technological differences.

This starkly contrasts conventional blockchains, which often exist in isolated silos, lacking the ability to communicate with one another. Also, The Polkadot network’s design makes it particularly well-suited for developing decentralized applications that utilize data from multiple blockchains.

Polkadot is already an established foundational layer. Therefore, it addresses many challenges developers face, including working with rigid layer-1 chains by providing a more adaptable base infrastructure. 

Governance is conducted directly by DOT token holders, who actively participate in voting to decide on proposals for making changes to the network. Polkadot introduced this democratic approach, OpenGov, earlier in 2023, granting every token holder a voice in shaping the platform’s evolution.

The Native Token of Polkadot Ecosystem

Polkadot’s native cryptocurrency, DOT, plays a pivotal role in the functionality and governance of the Polkadot network. DOT is not just a digital currency; it serves multiple purposes, including securing the network, enabling governance decisions, and acting as collateral for parachains. 

Let’s explore DOT’s various aspects and significance within the Polkadot ecosystem.

Staking and Network Security

One of the primary uses of DOT is staking. Validators responsible for producing blocks and validating transactions on the Polkadot network must stake a significant amount of DOT as collateral. 

This collateral serves as insurance against misbehavior. If a validator acts maliciously or fails to perform the required duties adequately, the system will slash a portion of its staked DOT. This model incentivizes validators to act honestly and maintain network security.

Governance Rights

DOT holders also have governance rights within the Polkadot network. Polkadot employs a decentralized governance model where token holders can propose, discuss, and vote on network upgrades and parameter changes. This system allows the community to actively participate in shaping the direction and policies of the network. 

Each DOT token represents a voting share, and the more DOT one holds, the more influence they have in the decision-making process. This governance structure promotes decentralization and ensures that changes to the network align with the community’s desires.

Bonding and Parachains

Bonding is a critical mechanism that plays a vital role in the Polkadot network’s operation, particularly in the context of parachains. 

Parachains are individual blockchains connected to the Polkadot Relay Chain, and they serve as the foundation for various decentralized applications and use cases. Projects or teams interested in launching a parachain must participate in a bonding process to secure a parachain slot on the Polkadot network.

Here’s a breakdown of the bonding process:

Collateral 

To bond and secure a parachain slot, a project or team must lock up a certain amount of DOT tokens as collateral. The amount of DOT required depends on several factors, including the duration of the slot lease and the specific auction dynamics at the time. 

This collateral is a form of insurance or security against misbehavior or disruptions on the parachain. If a parachain misbehaves or violates network rules, some or all of the bonded DOT can be slashed, thus providing a strong economic incentive for parachain candidates to act responsibly.

Competitive Allocation

Bonding introduces a competitive element to the allocation of parachain slots. Given the limited number of available slots and the willingness of different projects to lock up DOT tokens as collateral, the allocation process can become competitive. 

Projects more committed to the network’s success and can offer valuable services on their parachains are more likely to secure slots. This competitive mechanism ensures that only the most promising and reliable parachains are added to the network.

Network Sustainability

Bonding helps maintain the sustainability and security of the Polkadot network. It ensures that parachain operators remain committed to the network’s stability and success. 

This shared interest aligns with the broader goals of Polkadot, which is to create a secure, interoperable, and collaborative ecosystem of blockchains.

Incentives and Reward

Incentives and rewards are vital to Polkadot’s economic model, encouraging active participation in network security and consensus. These incentives are for validators and nominators, who contribute to the network in various ways:

Validators

Validators are key network participants responsible for producing blocks and validating transactions. They are selected through a staking process, where they must lock up a significant amount of DOT tokens as collateral. 

Validators are highly motivated to perform their duties correctly because they can earn rewards through additional DOT tokens. Conversely, if they behave maliciously or fail to meet network requirements, they risk losing some of their staked DOT tokens through slashing. 

This system ensures the security and integrity of the network.

Nominators

Nominators play a complementary role to validators. They support validators by staking DOT tokens with them. In return, they also receive a share of the rewards earned by validators. 

Nominators must carefully choose the validators they support to maximize their potential rewards while maintaining network security.

This system encourages a balanced and decentralized approach to staking and participation. The incentive structure in Polkadot promotes active involvement and contributes to the health and robustness of the network.

The network rewards validators and nominators for their contributions, ensuring the network’s security and enhancing its overall functionality and stability. This dynamic ecosystem of rewards and incentives helps create a self-sustaining and secure blockchain network.

The introduction of Polkadot 2.0 could positively impact the value of DOT tokens. With the new version, projects will require DOT to access core time, which could generate increased demand for DOT due to its role in network fees. This heightened demand for DOT tokens could drive up their value.

Furthermore, those holding surplus core time may choose to sell it on secondary markets, which could contribute to appreciating DOT’s value.

Additionally, the decentralized finance (DeFi) services offered on Polkadot present opportunities for DOT holders to earn rewards, further enhancing the utility and liquidity of the token.

A significant portion of the revenue generated from coretime sales will flow into the Polkadot Treasury, with DOT token holders having the authority to decide how these funds are distributed.

This governance approach ensures community involvement and alignment with the network’s interests. 

Unassigned tokens are also periodically burned, creating deflationary pressure on DOT, which helps maintain a balance in its supply. 

While these factors can influence the future value of DOT tokens, it’s essential to recognize that market dynamics, the level of adoption, and the evolution of the Polkadot ecosystem are pivotal in its price trajectory.

Additionally, developments like Polkadot 2.0 will also have a substantial impact on the token’s value.

Verdict – Will Polkadot 2.0 Thrive in Future?

The Polkadot network’s innovative approach to bridging disparate blockchains and the multifaceted utility of DOT tokens promise a dynamic and interconnected blockchain ecosystem.

By fostering interoperability, enabling bonding for parachains, and providing incentives through rewards, Polkadot is poised for significant growth. 

The introduction of Polkadot 2.0 further augments the potential value of DOT tokens. However, it is imperative to acknowledge that market dynamics, adoption levels, and ongoing ecosystem developments will be pivotal in shaping Polkadot’s future and DOT’s value. 

More so, the adaptability and community-driven governance position Polkadot for continued success in the ever-evolving blockchain landscape.
