BLACKROCK, THEN BITWISE — HOW THE SPOT BITCOIN ETF FILINGS DIFFER

Bitwise has revived its proposal for a spot Bitcoin ETF following a similar move by BlackRock and rumors of Fidelity pursuing one as well, even though the SEC has never approved such an offering. The Bitwise filing, like BlackRock's, emphasizes surveillance of Bitcoin via the CME futures markets. Analysts suggest Bitwise's move is a direct response to BlackRock's bid, and both filings cite the SEC's approval of a Bitcoin futures fund by Teucrium as a precedent. The outcome of Grayscale Investments' lawsuit against the SEC could further influence the prospects for approval of a spot Bitcoin ETF.

OPTIMISTIC POOL - A UNIVERSAL CO-PROCESSOR FOR ETHEREUM MAINNET

This proposal introduces the concept of an optimistic pool as a co-processor to Ethereum mainnet. It explains that an optimistic pool is a universal contract that offloads computations off-chain and validates them more efficiently on-chain, similar to roll-ups but without holding user tokens. The article mentions existing examples of co-processors being developed, such as WAX and Axiom. The optimistic pool being discussed is funded by Nouns DAO and aims to provide a low-cost solution for checking zk-proofs in a private voting system. This write-up provides an overview of how the optimistic pool works, covering claim kinds, blesser priority queue mechanics, and the blesser payout mechanism. It also suggests potential applications for the optimistic pool, such as private voting, Tornado Cash contracts, smart contract wallets, and optimistic aggregation of signatures.

SUPERCHARGED LIQUIDITY POOLS TO DEPLOY ON OSMOSIS

Osmosis, a decentralized exchange built on the Cosmos network, has received community approval to deploy supercharged liquidity pools. This upgrade allows liquidity providers to concentrate their assets and earn more rewards based on actual usage. The proposal received over 96% of the community's votes. The first supercharged pool will involve the DAI/OSMO assets. The migration of existing pools and the creation of new pools will follow a governance process until all curve pools on Osmosis are migrated. Whitelisted assets, including OSMO, USDC, and DAI, will be initially available for permissionless pool creation. The v16 upgrade is scheduled for late June.

DEFI LESSON: FRAGMENTED LIQUIDITY AND 1INCH

Fragmented liquidity is a condition in the DeFi market where liquidity is dispersed among various trading platforms instead of being concentrated in one pool. This can create challenges in finding sufficient liquidity, executing trades at desired prices, and ensuring efficient trading across different protocols. To address this, 1inch, a liquidity aggregator, combines liquidity from multiple exchanges and protocols to provide users with optimal prices and efficient transactions. By aggregating liquidity and splitting trades across different pools, DEX aggregators minimize slippage and maximize price efficiency.
