Did you know? The interaction between Polkadot and Solidity can further improve the ecological performance and realize new developer-friendly technical support. Specifically, Polkadot enhances its technical support for Solidity by introducing technologies such as PolkaVM and Revive. Revive can compile Solidity contracts into RISC-V code executable by PolkaVM , thereby enabling the operation of Solidity contracts on Polkadot.
Although current developers can successfully use Solidity for development in the Polkadot ecosystem through technical environment construction, contract writing and compilation, and project deployment interaction , performance compatibility, complex contract logic, and security challenges have become real obstacles that plague developers to conduct in-depth exploration. Many developers are standing outside the door of the Web3 world, eager to learn about blockchain development through systematic technology and knowledge, and master industry knowledge such as Polkadot, Solidity, and smart contracts. To this end, Oneblock+ organized a special event called "Don't Get Lost in Blockchain: Polkadot, Solidity, and Smart Contracts, All in One" . The first event was held online at 20:00 on the evening of February 28. Audience partners and development experts had in-depth exchanges to jointly explore the secrets of deep cultivation in the industry.

🧬Decentralized electronic payment Bitcoin
First, Mr. Zhou Jun started with the basic concept of Bitcoin, shared the basic points of digital assets, and the era background of the rise of the concept of decentralization . He pointed out that the emergence of Bitcoin has changed the traditional electronic payment method and can better complete smooth and fast asset transactions while ensuring user autonomy and privacy.
Decentralized payment can make it easier to verify the proof of digital assets, and without a centralized server, the system will not be paralyzed by the failure or intervention of a single institution; transactions will also be verified through asymmetric encryption (public key/private key) to ensure that the ownership of funds cannot be tampered with. With the obvious advantages of low cost and global availability, it is worth mentioning that after the birth of Bitcoin, all transaction records are publicly available on the blockchain, achieving high transparency and reducing fraud risks . It can be seen that the birth of Bitcoin has reshaped the traditional financial system, and its payment potential will be further released.
🧬 Ethereum and Smart Contracts
Afterwards, Mr. Zhou Jun demonstrated the Ethereum platform and smart contract functions, and made an in-depth analysis of how smart contracts provide automated technical solutions and their important features in practical applications. Ethereum is based on blockchain technology, and all transactions and contract codes are verified by global node consensus. Once the data is uploaded to the chain, it cannot be modified, ensuring the transparency and credibility of the execution results . The smart contract terms on its platform are automatically executed through code without human intervention.
Through actual scenario use cases, Ethereum is improving the platform's project operation capacity through expansion and interaction, and demonstrating higher efficiency and operational capabilities in financial transactions, supply chain management, voting governance, etc. In the future, Ethereum will also need to promote modularization and community collaboration, and demonstrate stronger user experience in terms of compliance and privacy enhancement.
🧬 Polkadot — The real Web3
The Web3 industry is developing rapidly, and the Polkadot ecosystem is also exploring new development directions in the ever-changing industry context, actively promoting innovative changes in Web3. For Polakdot, it is committed to achieving seamless interoperability between different blockchains, allowing each block to communicate and share data with each other, breaking the isolation between traditional blockchains , and achieving efficient exchange of information and data between parallel chains through the Cross-Chain Messaging Protocol (XCMP) without relying on centralized intermediaries. Its technical architecture mainly includes:
Relay Chain: The Relay Chain is the core of Polkadot, responsible for the security, consensus mechanism and cross-chain interoperability of the entire network. It serves as the central hub of the network, coordinating communication and data transmission between various parallel chains.
Parachains: Parachains are independent blockchains that run in parallel with the relay chain and can be customized for specific use cases. These chains can be homogeneous or heterogeneous, they share the security of the relay chain and achieve cross-chain interoperability through the relay chain.
Bridges: Bridges allow Polkadot to communicate and transfer data with other blockchains such as Bitcoin and Ethereum. Through bridges, Polkadot is able to connect to external blockchains, further enhancing its interoperability.
The development goal of Web3 is to create a decentralized, open and interconnected network environment , and Polkadot provides the foundation for achieving this goal through cross-chain technology. Its multi-chain architecture solves the scalability bottleneck of traditional blockchains, allowing the network to handle more transactions and users , which is crucial for large-scale applications of Web3. It further ensures the network's efficient operation requirements when facing high loads, reduces dependence on centralized institutions, and enhances users' control over data and assets.
🧬 Polkadot 2.0 and JAM
The current rapid development of Polkadot relies on the important upgrade iteration of Polkadot 2.0. Polkadot 2.0 aims to improve scalability, flexibility and user experience through a series of technical improvements ; JAM is the core technical upgrade of Polkadot 2.0, which replaces the existing relay chain architecture and introduces new technical functions, which will make the Polkadot ecosystem more flexible, efficient and user-friendly, and promote the rapid development of decentralized applications (DApps).
JAM's main technical core modules include Agile Coretime, Elastic Scaling, and Async Backing:
Agile Coretime: This is a new economic model that allows users to purchase computing resources (Coretime) on demand, which is more flexible than the existing auction system. Users can purchase Coretime in monthly batches and split and resell it on the secondary market.
Elastic Scaling: Supports dynamic expansion. Projects can rent additional computing cores as needed, allowing the network to dynamically adjust computing resources according to demand, thereby improving efficiency and performance.
Async Backing: Supports asynchronous transaction verification, reduces block time and increases transaction throughput; this feature has been launched on Polkadot, reducing block time from 12 seconds to 6 seconds and significantly improving the ecosystem's carrying capacity.
JAM's modular design, agile core time, and elastic expansion capabilities will make the Polkadot ecosystem more efficient and help Polkadot 2.0 become an important driving force for the development of the Web3 industry.
🧬 How to enter Polkadot through Solidity contract development
In order to better guide developers to understand the relationship between Solidity contracts and the Polkadot ecosystem , Mr. Zhou Jun demonstrated in detail the technical path and practical significance of interacting with Polkadot through Solidity contract development ; Solidity has a wide range of application scenarios on Polkadot, and can take advantage of the advantages of Polkadot parachains for further development and exploration . In fact, Polkadot supports a variety of development environments, including Substrate and Ethereum-compatible parachains (such as Moonbeam and Astar), which allow developers to write smart contracts in Solidity and deploy them to the Polkadot ecosystem.
In general, developers need to complete the recommended deployment and development process by selecting a suitable development environment, installing necessary development tools, writing Solidity contracts, testing and interacting , and finally developing decentralized applications and promoting them in the market. Through interactive learning at the seminar, many developers followed Mr. Zhou Jun to gain a preliminary understanding of the technical operations of Solidity contract development into Polkadot , and they also look forward to consolidating their skills in future courses!
