KALIEN the Asteroids game and what it says about ZK on Stellar

Developer showcases Kalion, a zero-knowledge proof-based Asteroids game on Stellar that enables off-chain computation with on-chain verification. The project demonstrates how ZK proofs can handle complex, computationally intensive tasks like 60 FPS gameplay over 10 minutes, proving fair play while minting Kalean tokens to winners.

Creating SEP-41 Dynamic Rebasing Token Balances On Stellar

A tutorial demonstrates building a rebasing token (RUSD) on the Stellar blockchain that accepts USDC deposits and automatically accrues yield by increasing holders' balances. The token uses a share-based system where added collateral, simulating yield from protocols like Blend, proportionally boosts all users' balances without needing to stake or interact further. Users can hold RUSD in their wallets and watch balances grow in real-time.

Stellar Developer Meeting: OpenZeppelin Q4 Releases

The Stellar Developer Meeting features the OpenSapplin team presenting Q4 2025 library releases: WAD for high-precision decimal arithmetic in Soroban smart contracts, fee abstraction for paying transaction fees with tokens like USDC instead of XLM, and the timelock module as the start of a governance package. These tools enhance developer experience, enable smart account functionality via relayers, and improve contract governance transparency and safety. The team highlights ongoing momentum and community adoption.

Balancing privacy with regulatory needs panel with Zama, Predicate and Stellar @ the Zama CoFHE Shop

At the Zama CoFHE Shop, the Stellar Development Foundation and Predicate discussed the emerging balance between privacy, compliance, and auditability on blockchains. SDF's Chief Product Officer Tomer argued that there is no one-size-fits-all approach to privacy. Instead, Stellar is building the cryptographic primitives so developers can layer whatever privacy solutions their use cases require. Predicate's head of business development emphasized that privacy and compliance evolve together, not sequentially. Key blockers to adoption include the lack of user-friendly products and regulatory uncertainty. SDF announced Protocol 25 X-Ray, bringing cryptographic building blocks (pairing-friendly elliptic curves, Poseidon hash functions) to Stellar, along with integrations for Noir, a zero-knowledge DSL, and RISC-Zero verifiers. SDF is collaborating with Nethermind on Stellar Private Payments, a privacy-preserving protocol based on Privacy Pools research, and shipping a confidential tokens implementation. The consensus: the cryptographic infrastructure is ready; the market needs better products and regulatory clarity.
