The VeChain Hayabusa upgrade is the second phase of the VeChain Renaissance. The Hayabusa upgrade will upgrade VeChainThor’s consensus mechanism, tokenomics and degree of decentralization.​ ​ Key Highlights:​ - **Upgrade to Delegated Proof of Stake (DPoS)**: VeChainThor will migrate from PoA to DPoS, a more decentralized consensus mechanism, while maintaining strong security and performance.​ - **Enhanced VTHO Tokenomics**: A dynamic VTHO generation rate will be distributed as a block reward to validators and delegators that contribute to securing the VeChainThor network.​

Avon is building an entirely new way to borrow and lend on chain via lending infrastructure designed for efficiency, composability, and real-time dynamics. We combine the granularity of an order book with programmable lending markets (strategies), bringing true market dynamics to onchain lending. Avon enables competitive rates, real-time price discovery and flexible lending terms (expressivity).

Alchemix is your unified platform for saving, earning, borrowing, and fixed-term fixed-yield opportunities—all in one place. Built on years of iteration since launching the original self-repaying loan in 2021, Alchemix v3 brings all three pillars together with a smarter, more flexible design.

The Centrifuge Protocol is an open, protocol for onchain asset management. Built on immutable smart contracts, it enables permissionless deployment of customizable tokenization products. Build a wide range of use cases, from permissioned funds to onchain loans, while enabling fast, secure deployment. ERC-4626 and ERC-7540 vaults allow seamless integration into DeFi. Using protocol-level chain abstraction, tokenization issuers access liquidity across any network, all managed from one Hub chain of their choice. The contest focuses on the v3.1 release, which adds onchain accounting, an improved multi-chain messaging system, a refactored core module that increases modularity, and more.
