🔗 Withdrawable signatures in Fiat-Shamir with aborts constructions
This paper explores withdrawable signatures, a novel cryptographic mechanism that allows signers to revoke signatures efficiently without exposing private keys or affecting other valid signatures. This capability has significant implications for:
· Smart contracts – Enabling flexible commitments in multi-party agreements.
· Decentralized voting – Allowing voters to adjust their decisions before final tabulation.
· Escrow & multi-party transactions – Providing a secure way to manage disputes.

🔗 Starknet on Bitcoin and Ethereum: The first L2 to unify both chains
Starknet is embarking on a journey to lift both of those limitations and unleash Bitcoin’s full potential, all while preserving its core principles. Developed in part by the inventors of STARK proofs, Starknet will become the first Layer 2 to settle on both Bitcoin and Ethereum, unifying the world’s largest blockchains on a single layer. The goal is to serve 1 billion Bitcoin users, introducing improved UX, scale, and liquidity—all without compromising on security or decentralization.

🔗 No forks given — Bitcoin DeFi without upgrades
The goal is to scale Bitcoin to thousands of transactions per second while introducing all the DeFi trappings like yield farming, staking, and lending — but without waiting for Bitcoin’s meandering governance process.
The idea has growing proponents. A broader push to unlock Bitcoin’s smart contract potential without protocol changes started with research breakthroughs in the form of BitVM, followed by Starknet-backed ColliderScript, and most recently Bitcoin PIPEs.

While staked assets earn passive rewards, they could be more active across ecosystems, fueling new opportunities for lending, borrowing, and cross-chain interactions.
Ethereum, for example, over 33 million ETH is staked, worth approximately USD 108 billion (at $3,200 per ETH). Combined with other blockchains like Solana, Avalanche, and Cardano, the total value of staked assets exceeds USD 340 billion. (data provided by @StakingRewards )
Solana airdrops are great, and ISPOs on Cardano can generate some rewards, but this capital sits idle and while securing the network and validating transactions, it is not used to its full potential.

RISC Zero/Boundless@RiscZero announced improvements to its zkVM, making it more efficient with seven new precompiles. @AutomataNetwork reduced cycles from 30M to 5.4M using P256 (5.5x), @malda_xyz cut from 11M to 4M with Keccak (2.75x), and @TokemakXYZ improved from 91M to 29M… pic.twitter.com/qVBxis2tjW

🔗 Bitlayer’s BitVM Ecosystem, Now Supercharged by Celestia’s Data Solutions
Celestia is a modular blockchain network enabling the development of scalable blockchains via separating the consensus and data availability layers from the execution layer.
Infrastructure on Bitcoin previously struggled to make a high volume of transactions feasible due to block size limits, much of which is now alleviated by Celestia’s solutions.
Bitlayer’s focus on the emerging BTCFi sector requires high throughput, large batches of transactions, quick transactions, and a host of other features enabled by Celestia’s product suite
