What is SDN: A Comprehensive Guide to Software-Defined Networking Architecture and Implementation

Shiden Network's Positioning and Significance

In 2021, the team behind Plasm Network launched Shiden Network (SDN), designed to address the lack of smart contract functionality on Kusama's relay chain and the need for a versatile multi-chain dApp layer.
As a multi-chain decentralized application layer on Kusama Network, Shiden Network plays a key role in DeFi, NFTs, and cross-chain interoperability.

As of 2026, Shiden Network has established itself within the Kusama ecosystem, with an active development community and support for Ethereum Virtual Machine, WebAssembly, and Layer2 solutions.
This article will provide an in-depth analysis of its technical architecture, market performance, and future potential.

Origin and Development History

Birth Background

Shiden Network was created by the Plasm Network team in 2021, aiming to solve the absence of smart contract capabilities on Kusama's relay chain and enable diverse blockchain applications.
It emerged during the rapid expansion of the Polkadot and Kusama ecosystems, with the goal of providing a comprehensive smart contract platform that bridges multiple blockchains.
Shiden Network's launch brought new possibilities for developers and users seeking to build decentralized applications on Kusama.

Important Milestones

• 2021: Mainnet launch, achieving multi-chain support with EVM and WebAssembly compatibility from inception.
• 2021: PLM token holders were able to claim SDN tokens at a 1:1 ratio, establishing the initial token distribution.
• The network has continuously evolved its Layer2 solutions and cross-chain bridge capabilities to enhance performance and interoperability.

With support from the Astar Network foundation and the broader Kusama community, Shiden Network continues to optimize its technology, security, and real-world applications.

How Does Shiden Network Operate?

No Central Control

Shiden Network operates on a decentralized network of computers (nodes) distributed globally, free from control by banks or governments.
These nodes collaborate to validate transactions, ensuring system transparency and attack resistance, granting users greater autonomy and enhancing network resilience.

Blockchain Foundation

Shiden Network's blockchain is a public, immutable digital ledger that records every transaction.
Transactions are grouped into blocks and linked through cryptographic hashes to form a secure chain.
Anyone can view the records, establishing trust without intermediaries.
The platform's support for multiple virtual machines (EVM and WebAssembly) and Layer2 scaling solutions further enhances performance and flexibility.

Ensuring Fairness

Shiden Network utilizes Nominated Proof of Stake (NPoS) to validate transactions and prevent fraudulent activities such as double-spending.
Validators and nominators secure the network through staking SDN tokens and participating in consensus, earning SDN rewards for their contributions.
Its innovations include efficient cross-chain communication and compatibility with diverse blockchain standards.

Secure Transactions

Shiden Network employs public-private key cryptography to protect transactions:

• Private keys (similar to secret passwords) are used to sign transactions
• Public keys (similar to account numbers) are used to verify ownership

This mechanism ensures fund security while transactions maintain pseudonymity.
The network's multi-chain architecture and bridge protocols provide additional layers of security and interoperability.
