Golden Finance reported that, according to SEC official documents, the U.S. SEC has accepted the submission of the amendment for the Franklin Crypto Index ETF. On August 17, Franklin Templeton submitted the S-1 application for the new crypto index ETF, aimed at becoming a one-stop cryptocurrency portfolio. The Franklin Crypto Index ETF will track the performance of the CF Institutional Digital Asset Index, which currently only includes Bitcoin and Ethereum. If approved, the proposed Franklin Crypto Index ETF will be listed on the Cboe BZX exchange and will use Coinbase Custody Trust Company LLC as its digital asset custodian. The ETF plans to invest in crypto assets with weights similar to the underlying index, with the possibility of adding other types of cryptocurrencies in the future.

Golden Finance reported that Anza has proposed two measures to implement a penalty mechanism (slashing) in the network, primarily targeting so-called 'duplicate blocks' to penalize validators, which refers to the situation where the same block is created twice. Anza has not yet decided on the specific economic details of the penalty mechanism, but the author of SIMD suggested destroying (or functionally abolishing) the punished staked tokens. Anza's Ashwin Sekar also proposed a parabolic penalty curve: if 5% of a validator's staked tokens violate the rules, then 1% of their staked tokens will be destroyed; while if 33% of the staked tokens violate the rules, all staked tokens will be penalized. Sekar explained in a validator discussion that Ethereum's penalty curve is linear. Sekar also stated that this penalty proposal is still in its early stages, and such an update will not be released until at least the end of summer 2025.

On December 19, news came that Gavin Wood, the founder of Polkadot, recently announced the latest progress of JAM during the Polkadot Fellowship Call. Important information is as follows: 1. JAM SDK: Parity has released v0.1, supporting Rust developers to create services and upload them to JAM. 2. CoreVM: Parity will launch the initial version of CoreVM by January at the latest, which is the first official service; it innovatively allows arbitrary code to run on the blockchain without being constrained by Gas limits or block limits, achieving true Turing completeness; in addition, Gavin hopes to release a demo of the DOOM game soon, which will showcase the capabilities of JAM and PVM. 3. JAM 1.0: The fully functional version is expected to be completed before April 2025 and enter the audit phase. 4.
