Goal
Ban an account whose activity may harm the dApp functioning, as well as the blockchain as a whole.
Before you begin
Install the currently supported version of cleos.
Understand the following:
Who is a Golos application leader.
What is a multisig propose transaction.
Steps
Step 1
Identify accounts whose activities are causing a negative reaction. Assume these are: usr11uyviduc, usr11xzbpec, usr11vzjrqzl, usr11deuytwa.
Step 2 Create transactions containing the action ban to block each of the listed accounts. You can call the action ban from contract gls.ctrl using command line cleos.
1
$ for i in <account-1> ... <account-n>; do
2
    cleos --url http://<node> push action gls.ctrl ban '["'$i'"]' --bandwidth-provider gls.ctrl/gls -p gls.ctrl -d -s -x <expiretime> 2>> <file_name.trx>
3
done
Copied!
Example
1
$ echo > ban.trx
2
$ for i in usr11uyviduc usr11xzbpec usr11vzjrqzl usr11deuytwa; do
3
    cleos --url http://seed-1:8888 push action gls.ctrl ban '["'$i'"]' --bandwidth-provider gls.ctrl/gls -p gls.ctrl -d -s -x 1209600 2>> ban.trx

done
Copied!
The name "i" is a loop parameter which are sequentially assigned the listed accounts.
To prevent the transaction from becoming expired while signatures are being collected, you have to set the transaction expiretime, for example, 14 days that is 1209600 in seconds (60×60×24×14=1209600). The maximum allowable time is 45 days.
Resulting actions code is saved in the file ban.trx.
Step 3 Edit the file ban.trx to put the actions in one transaction.
Step 4 Retrive a list of active leaders who have right to sign a transaction.
This list can be retrieved from the gls account authorization:
1
$ cleos -u http://seed-1:8888 get account -j gls
Copied!
From the result output, select and save the list of actors that will look like:
Actors accounts
Step 5 Edit the list of active leaders. Convert the active leaders list to string form like this one [{"account", "permission"}, ... ,{"account", "permission"}].
Example
1
[{"actor": "lavnch3wug2o","permission: "active"},{"actor": "2cv2urmf2pud","permission: "active"}, ... ,{"actor": "rtvmqvzi5lvt","permission: "active"}]
Copied!
Step 6 Submit the proposal. The proposal can be submitted by any user. It is created via propose taken from the contract cyber.msig.
The command line looks like this one:
1
$ cleos -u http://<node> multisig propose_trx <proposal_name> permissions.json <file_name.trx> <proposer> -p <proposer>
Copied!
Example
1
$ cleos -u http://seed-1:8888 multisig propose_trx ban.badusers permissions.json ban.trx shwojevqcywn -p shwojevqcywn
Copied!
Step 7 Pass the transaction to leaders for signing.
The link can be taken from author of the proposal.
Example
Leaders can go to https://explorer.cyberway.io/account/shwojevqcywn/proposals/bad.badusers/4 and sign the transaction.
