In a blockchain system, depositing and withdrawing software upgrade proposals require careful handling, as this involves changes to the blockchain network and trust between participants.↵↵In some blockchain systems, such as Ethereum, depositing and withdrawing software upgrade proposals are indeed supported. Ethereum has many decentralized applications (DApp) through smart  contracts, and developers can submit upgrade proposals to improve and optimize smart contracts. However, these upgrade proposals need to be approved by a certain ratio of network participants' votes to ensure that they are secure and stable."}]}],"pr":"5b23795bdceec8acadcbb618bc7ca6bfc8e3615edb8d3426d8166164e5361eb8"}
