Here's a case study on a high-performance Layer 1 blockchain built on Cosmos. title: Shido Case Study --- ## Shido # High-Performance Layer 1 Blockchain Built on Cosmos Infrastructure Delivered an EVM-compatible Layer 1 network with instant finality, optimized state execution, and cross-chain connectivity for enterprise-scale decentralized applications. [Build Your Layer 1 Blockchain]() ![Web3 AI](https://www.antier.com/wp-content/uploads/2026/05/Group-2085668826.png) ## About the Client The client is a technology-oriented organization focused on building modern blockchain networks under the Shido initiative. Developed in the Cosmos ecosystem, Shido is a Layer 1 network created to power decentralized applications with speed and EVM support.   The platform combines Cosmos-based performance with Ethereum smart contract compatibility, allowing developers to build familiar EVM applications while benefiting from lower latency and stronger throughput. Focused on real-world usability, Shido was designed to support enterprise-grade workloads, secure transaction processing, and multi-chain connectivity across blockchain ecosystems. ![Web3 AI](https://www.antier.com/wp-content/uploads/2026/05/fi_558593.png) #### Website https://shido.io/ ![Web3 AI](https://www.antier.com/wp-content/uploads/2026/05/fi_11160247.png) #### Founded 2021 ![Web3 AI](https://www.antier.com/wp-content/uploads/2026/05/fi_535239-1.png) #### Location Sweden ## Problem Statement Existing blockchain ecosystems often force teams to choose between performance, compatibility, and interoperability. Cosmos-based networks can deliver speed and efficient consensus, yet many lack the native EVM support required by Ethereum developers. EVM chains offer a familiar smart contract environment, though rising state overhead and scaling limits can reduce efficiency under heavy workloads. Cross-chain systems are frequently limited to token movement, while deeper application-level communication remains difficult. State storage also becomes a major constraint when processing large transaction volumes over time. ## The client wanted a blockchain network that could: ![Web3 AI](https://www.antier.com/wp-content/uploads/2026/05/fi_9332477.png) ##### Run high-volume EVM workloads efficiently ![Web3 AI](https://www.antier.com/wp-content/uploads/2026/05/fi_11726625.png) ##### Maintain instant and deterministic finality ![Web3 AI](https://www.antier.com/wp-content/uploads/2026/05/fi_12407431.png) ##### Support smart contract interaction across chains ![Web3 AI](https://www.antier.com/wp-content/uploads/2026/05/fi_9644854.png) ##### Remove limitations found in Cosmos and Ethereum environments ## The Objective ![Web3 AI](https://www.antier.com/wp-content/uploads/2026/05/01-10.png) ##### High-Throughput EVM Execution ![Web3 AI](https://www.antier.com/wp-content/uploads/2026/05/02-11.png) ##### Instant Transaction Finality ![Web3 AI](https://www.antier.com/wp-content/uploads/2026/05/03-11.png) ##### Multi-Chain Interoperability ![Web3 AI](https://www.antier.com/wp-content/uploads/2026/05/04-11.png) ##### Efficient State Processing ![Web3 AI](https://www.antier.com/wp-content/uploads/2026/05/05-4.png) ##### Enterprise-Ready Infrastructure ## The Solution Shido was engineered through custom low-level enhancements across storage systems, execution layers, consensus integration, and interoperability modules. Rather than depending on default frameworks, the network introduced purpose-built infrastructure designed for speed, reliability, and large-scale usage. ![](http://www.antier.com/wp-content/uploads/2026/05/Group-2085666251-1.svg) ![](http://www.antier.com/wp-content/uploads/2026/05/Rectangle-34625299.svg) ![](http://www.antier.com/wp-content/uploads/2026/05/Rectangle-34625299-1.svg) ![](http://www.antier.com/wp-content/uploads/2026/05/Group-2085668780-1.svg) ## Core Features ![Web3 AI](https://www.antier.com/wp-content/uploads/2026/05/Margin-9.png) #### Optimized State Management -
