Real-World Impact: Our Success Stories
We don't just build technology; we build solutions that drive tangible results. Explore how we've helped clients launch successful public blockchain networks.
Case Study: Launching a High-Yield DeFi Lending Protocol
Industry: Decentralized Finance (DeFi)
Client Overview: A well-funded FinTech startup aimed to disrupt the traditional lending market by creating a decentralized, cross-chain lending and borrowing protocol. Their goal was to offer higher yields than competitors by integrating with multiple yield farming strategies while ensuring top-tier security for user funds.
"Errna was more than a vendor; they were our architectural partner. Their expertise in both DeFi security and Layer-2 scaling was critical to our successful launch. We went from a whitepaper concept to a top 20 DeFi protocol in under a year." - Julian Ford, Founder, NexusFi
Problem
The client needed to build a highly secure, scalable, and interoperable DeFi protocol from scratch. The existing DeFi landscape was competitive, and success depended on offering unique features, ensuring user funds were safe from exploits, and providing a seamless user experience with low transaction fees.
Key Challenges
- Ensuring smart contract security against flash loan attacks and other exploits.
- Achieving low transaction costs and high speed on the Ethereum network.
- Building a secure cross-chain bridge to attract liquidity from other ecosystems.
- Designing a governance model that would encourage community participation.
Our Solution
We developed an end-to-end solution that addressed every challenge:
- We architected and developed the entire protocol on an Arbitrum Layer-2 solution to minimize gas fees and improve transaction speed.
- Our team wrote and rigorously audited all smart contracts, implementing time-locks, price oracle safeguards, and formal verification to prevent common attack vectors.
- We built a custom, audited cross-chain bridge using a light client and relayer model to securely connect with the BNB Smart Chain.
- A comprehensive DAO structure was implemented, complete with a governance token, on-chain voting, and treasury management smart contracts.
Case Study: Building a Public Blockchain for an NFT Gaming Metaverse
Industry: Gaming & NFTs
Client Overview: An established gaming studio wanted to create a decentralized metaverse, giving players true ownership of their in-game assets. They needed a dedicated public blockchain that could handle millions of daily transactions, support complex game logic, and offer a frictionless experience for non-crypto-native gamers.
"The decision to build our own chain was daunting, but Errna's team made it manageable. Their understanding of both blockchain performance and game development needs was exceptional. Our 'Aetherium' chain is now the backbone of our entire ecosystem." - Camila Gilmore, CEO, PixelForge Studios
Problem
Existing public blockchains were either too slow or too expensive for the high-frequency, low-value transactions typical of gaming. The client required a custom blockchain optimized for gaming performance, asset interoperability, and ease of use for a mainstream audience.
Key Challenges
- Achieving sub-second transaction finality for a seamless gaming experience.
- Designing a network economy that could support millions of NFTs without hyperinflation.
- Creating a wallet and onboarding process simple enough for first-time crypto users.
- Ensuring the chain was decentralized enough to guarantee true asset ownership.
Our Solution
We engineered a custom public blockchain using the Cosmos SDK:
- We implemented a Delegated Proof-of-Stake (DPoS) consensus mechanism to achieve high throughput and fast finality, essential for real-time gameplay.
- Our team designed a dual-token economy: one for gas and staking, and a stable utility token for in-game purchases to create a stable economic environment.
- We developed a custom wallet with social login (Web2 auth) integration, which created a non-custodial wallet in the background, abstracting away seed phrases for new users.
- The chain was launched with a diverse set of 50 genesis validators to ensure robust decentralization from day one.
Case Study: A Public Network for Supply Chain Traceability
Industry: Logistics & Supply Chain
Client Overview: A consortium of agricultural producers wanted to create a public, transparent record of product provenance to combat counterfeiting and prove authenticity to consumers. They needed a public blockchain that was low-cost, easy to integrate with existing IoT devices, and provided a permanent, immutable ledger.
"Errna helped us build trust into our supply chain. The public ledger they developed allows anyone, from regulators to consumers, to verify the journey of our products. This transparency has become our biggest competitive advantage." - Marcus Dyer, Head of Innovation, AgriChain Consortium
Problem
Private blockchains lacked the public trust and accessibility needed for consumer-facing verification. The client required a public chain that could store large amounts of traceability data immutably and cost-effectively, while being simple for non-technical staff at farms and warehouses to use.
Key Challenges
- Storing large volumes of supply chain data on-chain without incurring massive costs.
- Creating a simple mobile interface for workers to scan products and upload data.
- Ensuring data integrity from IoT sensors (e.g., temperature, humidity).
- Making the traceability data easily accessible and understandable for end consumers.
Our Solution
We developed a hybrid solution leveraging a custom public blockchain:
- We built a custom public blockchain based on a Proof-of-Authority (PoA) consensus model, where consortium members run validator nodes, ensuring low costs and high performance.
- To manage data costs, we used a "hashing" approach: raw data was stored on IPFS (a decentralized storage network), and only the immutable hash of that data was recorded on the blockchain, ensuring tamper-proof verification.
- We developed a progressive web app (PWA) that allowed workers to easily scan QR codes on shipments and upload data from their mobile devices.
- A public-facing explorer was created, allowing anyone to scan a product's QR code and see its entire journey from farm to shelf on an interactive map.

Frequently Asked Questions
Have questions? We have answers. Here are some common queries about public blockchain development.
A public blockchain (like Bitcoin or Ethereum) is permissionless, meaning anyone can join the network, read the ledger, and participate in the consensus process. This offers maximum decentralization and censorship resistance. A private blockchain is permissioned, restricting access to a select group of participants, which provides more control, privacy, and often higher performance, but sacrifices decentralization.
The timeline varies significantly based on complexity. A simple fork of an existing blockchain might take 3-6 months. Building a completely new public blockchain from scratch with a unique consensus mechanism, custom features, and a full ecosystem can take 12-24 months or more from conception to mainnet launch.
Security is our top priority and is embedded in our entire process. We use secure coding practices, build on battle-tested frameworks, conduct multiple rounds of internal testing, and engage third-party auditors to perform comprehensive security audits on the core protocol and smart contracts. We also design tokenomics that economically incentivize honest behavior and disincentivize attacks.
Costs can range from $100,000 for a basic implementation or fork to several million dollars for a complex, custom-built blockchain with a full ecosystem of dApps, wallets, and community-building initiatives. We provide detailed, transparent pricing based on a thorough discovery and scoping process.
We address scalability from day one in the architectural design phase. Our primary strategies include implementing Layer-2 solutions like Optimistic or ZK-Rollups, designing efficient consensus mechanisms (like Proof-of-Stake), and optimizing code at the protocol level. This ensures your network can support high transaction volumes at a low cost to users.
While our core focus is on development, we have a strong network and can provide strategic guidance and introductions to help you navigate the token listing process. We ensure your blockchain's technology and documentation meet the high standards required by reputable exchanges.
