In this July 22, 2024 code update for Sky Protocol on Cardano, lead developer Fro demonstrates basic Reed-Solomon encoding to decompose and recompose data strings using Lagrange interpolation over finite fields (e.g., GF(256)). He showcases clean code for polynomial operations, addition, and multiplication, while discussing future DEX-like block space dynamics, supply-demand matching, security via democratic voting, and optimal collateral for nodes to balance capital efficiency and security.
In this December update for Sky Protocol on Cardano, COO Gauthier and lead developer François discuss Catalyst-funded progress on smart contracts in Plutus, node software transitioning from Scheme to Haskell, adaptations to Ouroboros for multi-topic consensus using the SKY token, new hires for gossip protocol development, the token's staking and utility roles, comparisons of rollups vs. data availability for scalability, and the node sale model starting with proof-of-authority before upgrading to proof-of-stake in 2025.
In this November 30, 2024 code update for Sky Protocol on Cardano, COO Gauthier and lead developer François discuss merging smart contracts into the main repository, rewriting node software from Scheme to Haskell for better ecosystem integration, and adapting Ouroboros. They detail simple Plutus contracts like Sky Minting Policy for NFTs, Bridge Contract with multi-sig for state updates, and a bounty example, alongside an efficient Trie library using wrappers and zippers for Merkle proofs. Early gossip protocol work is highlighted, with plans for a Q1 2025 testnet, Catalyst 13 voting, and future discussions on data availability attacks.
In this January 2025 code update for Sky Protocol on Cardano, COO Gauthier and lead developer François highlight Plutus smart contract enhancements, JavaScript testing, and Trie data structures using zippers for efficient Merkle proofs. They outline bridge integration for data publishing, February API release, centralized testnet, Docker-based node distribution, upcoming node sales, and a tokenless L3 version for other chains.
In this February 2025 Sky Protocol update, developer Manuel Simoni explains the Plutus-based Bridge Contract for Cardano’s Layer 2 Data Availability, using NFTs to store Merkle tree root hashes for scalability. He details multi-signature updates, client contracts like bounties, and Merkle proof validation, ensuring secure data verification.
In this February 2025 Sky Protocol update, developer Iaroslav Kozhevnikov discusses backend work on nodes and simple Merkle tries for Cardano's data availability, emphasizing off-chain storage with on-chain proofs for scalability. He covers implementation challenges like double proofs, integration tests, API simplicity for dApps, and plans for Milestone 4, trie upgrades, and testnet.
In this March 2025 Sky Protocol update, Gauthier and François discuss Catalyst Milestone 4, integrating advanced Merkle trie code for Cardano’s Layer 2 Data Availability. They explain tries for efficient data access, node sale plans, and a bounty contract validation using Plutus, with Docker-based node distribution and a potential incubator announcement.
In this April 2025 update on Sky Protocol's node sale for Cardano's Layer 2 Data Availability solution, COO Gauthier and lead developer François explain transitioning from proof-of-authority (PoA) to proof-of-stake (PoS), starting with a PoA node sale for 100-1,000 nodes priced at 10,000-20,000 ADA each, offering early fees, governance, and future SKY token conversion. They detail incentives like royalties, hardware requirements (similar to Cardano nodes), partnerships for testing the API and testnet, and long-term goals for business intelligence tools, aiming for a mainnet by Q4 2025 and a $500 billion data querying market by 2032.
In this April 2025 update on Sky Protocol's Cardano Layer 2 Data Availability testnet, lead developer François and COO Gauthier explain the centralized initial release for dApp builders, enabling 1,000x faster data publishing via simple code integration. They vulgarize sharding and erasure coding, invite feedback, and plan decentralization later in 2025 despite minor delays.
In this May 2025 Sky Protocol update, COO Gauthier and lead developer François discuss testnet delays due to Haskell-Plutus compatibility issues for real-time data access, acceptance into CVVC's Lunar Strategy incubator with AWS/Google compute grants, upcoming LambdaConf presentation on orthogonal persistence and zippers, and plans for rebranding and expanded development.
In this July 2025 Sky Protocol update, COO Gauthier and lead developer François discuss progress on the Cardano Layer 2 testnet, delayed by Haskell’s strict architecture but nearing completion with API endpoints. They highlight robust code design for future scalability, ongoing CV Labs incubator insights, and plans for documentation and node sale by mid-July.
In this August 2025 Sky Protocol update from ETHCC and Devcon, COO Gauthier and lead developer François report the Cardano Layer 2 testnet code is complete but delayed by a Plutus-Haskell bug, with outreach to developers for resolution. They discuss community feedback, mind map plans, code commentary, documentation, and potential AI integration.
In this August 2025 Sky Protocol update, COO Gauthier and lead developer François announce the Cardano Layer 2 testnet code is complete after resolving a Plutus bug with Cardano Foundation help. They explain code components, Olapa for B2B revenue, address token holder queries and roadmap delays, and plan a demo, Twitter Space, and testnet launch by Thursday, with builder interviews next week.
In this August 2025 Sky Protocol demo, lead developer François showcases the operational Cardano Layer 2 testnet, guiding dApp builders to set up the environment using Nix and Cabal, run tests, and interact with the Sky DA on the Cardano preview network. The demo covers creating topics, sending messages, updating the bridge contract with NFT-based Merkle root hashes, and verifying transactions in under 20 minutes.
In this August 2025 Sky Protocol Catalyst Fund 12 report, chief scientist François-René Rideau details their Cardano Layer 2 data availability solution, featuring an optimized Merkle Patricia trie with zippers, Plutus contracts for verification, and a centralized testnet. Despite Plutus-Haskell challenges and delays, they successfully built topic creation, message publishing, and bridge updates, with plans for decentralization, node sales, and an Olapa tool for secure data logging.
