The current deposit for a governance proposal is 10 STRD, worth approximately $3 in the current market. 2000 STRD has a current market value of approximately $600 and represents a more significant penalty to discourage spam proposals such as Proposal 14. Deposits may be filled by more than one party using the command line or wallet interfaces, such as Commonwealth and ping.pub, to ensure that the community is not priced out of governance. Governance participants should regularly re-evaluate this parameter against STRD price to ensure it is an appropriate spam deterrent whilst also being accessible.
Proposal 19 has wrong subkeys, so it won't affect on blockchain parameters.
