[TRON Developer Community Releases Explanation for TIP-6780 Instruction Change] On November 19, the TRON Developer Community published an explanation titled 'TIP-6780: Change to the SELFDESTRUCT Opcode' on Medium and discussed the impact of the instruction change during a recent developer meeting. This change will be incorporated into the upcoming java-tron v4.8.1 version but will not take effect immediately upon the version's release. The activation time will be determined later through on-chain governance voting. The core adjustment of TIP-6780 is to restrict the usage scenarios of SELFDESTRUCT, allowing it to delete account data only within the same transaction in which the contract is created. Additionally, the fixed energy cost will be adjusted from 0 to 5000 to reduce the risk of abuse. Statistical analysis shows that contracts containing the SELFDESTRUCT instruction account for an extremely low proportion on the TRON network, and the impact on existing contracts and user assets is expected to be minimal.

[Wintermute Submits Comment Letter to SEC, Proposes Adjustments to On-Chain Settlement and DeFi Proprietary Trading Regulations] Wintermute submitted a comment letter to the SEC's Special Working Group on Crypto Assets, proposing two recommendations: 1. Allow traders to independently manage on-chain settlement processes. Wintermute argues that regulated traders conducting on-chain settlements for their own accounts should not be deemed in violation for bypassing traditional clearing institutions. As long as counterparties can independently manage their wallets and complete on-chain delivery, and traders fulfill their settlement obligations, they should be exempt from the application of the 'Customer Protection Rule.' This aims to reduce intermediaries and improve blockchain settlement efficiency. 2. Proprietary trading on DeFi should not require trader registration. Wintermute believes that engaging solely in proprietary trading on DeFi protocols (including liquidity provision) without involving client interactions, market-making obligations, advisory services, or asset custody should be classified as 'traders' rather than 'dealers,' and thus not require registration. This perspective aligns with the legal trend following the court's overturning of the 'Dealer Rule' in 2024. Wintermute emphasizes that regulations should avoid imposing undue burdens on the decentralized finance ecosystem.
