Odaily reports: Optimum has announced that its block propagation software mump2p has officially launched on the Ethereum mainnet. ether.fi previously offered the software as an optional feature, but has now mandated its adoption across all 12 of its node operators. Currently, a total of 16 node operators are running mump2p in production environments, collectively managing approximately 22,000 validator keys and over 1.4 million staked ETH, accounting for more than 3% of Ethereum's total staked supply. Partners include Blockdaemon, Everstake, P2P.org, Stakefish, and Bitcoin Suisse.mump2p operates as a sidecar gateway, rather than replacing Ethereum's default GossipSub, it layers on top of libp2p and uses random linear network coding technology. Optimum claims that mump2p achieves block arrival speeds 2.42 times faster than GossipSub, with arrival time variance reduced by approximately 7.88 times. Optimum is led by MIT professor Muriel Médard and launched its private testnet in June 2025. The company previously completed an $11 million seed round led by 1kx and plans to expand to other high-throughput blockchains beyond Ethereum.
According to CoinDesk, Fidelity plans to add ETH staking functionality and a quarterly cash distribution mechanism to its spot Ethereum ETF—the Fidelity Ethereum Fund (FETH). FETH currently has a net asset value of approximately $898 million and can stake up to 100% of its held ETH under normal circumstances. Under the arrangement, Fidelity will retain 85% of the staking rewards, with the remaining 15% allocated to the fund sponsor, custodian, and node operators (including Blockdaemon, Figment, and Galaxy). Net staking rewards will be prioritized to cover fund operating expenses, with the remainder distributed to investors as cash on a quarterly basis. This move is driven by a safe harbor announcement released by the U.S. Internal Revenue Service in November 2025, which allows eligible crypto trusts to stake without losing their grantor trust tax status.
Sui Foundation and Mysten Labs launched the Bitcoin mortgage protocol Hashi testnet on July 22, allowing BTC to provide collateral support for on-chain lending and credit markets without being wrapped into synthetic tokens or bridged across chains. Hashi keeps Bitcoin on the Bitcoin network, with deposits secured by a 2-of-2 multi-signature mechanism that requires simultaneous signatures from Hashi's multi-party computation validators and an independent Guardian Layer. Loan terms and collateral positions are recorded on-chain, allowing lenders to view the collateral backing. Over 25 institutional partners are testing Hashi's lending and credit applications, including Bitgo, Cumberland, FalconX, Ledger, Blockdaemon, Bullish, as well as Sui ecosystem lending platforms Navi and Scallop. Wave Digital Assets has committed to advancing a three-year Bitcoin yield bond tokenization plan on Sui after the Hashi mainnet launch. Hashi has not yet announced a mainnet launch date. Sui previously unveiled the Hashi development network phase in March, positioning the protocol as a solution to improve capital efficiency for the approximately 1.4 trillion dollar Bitcoin market.
