I don’t use any desktop or mobile wallets for my main account, so I had to look up the transaction details of the new EOS referendum contract. It’s fairly simple, you pass 0 or 1 as your vote, for No and Yes respectively. The last parameter is empty. Here we go, as I oppose the “1 token = 1 vote” initiative:
cleos wallet unlockalias mcleos='cleos -u http://mainnet.eoscalgary.io'mcleos push action eosio.forum vote '["cc32dninexxx", "1token1vote", 0, ""]' -p cc32dninexxx@active
That’s it, and very simple. You can see the list of initiatives at Bloks.io or at EOS Authority.
