Even 'admin' cannot subscribe/publish to read & write restricted stream

Wed, 11 Sep 2019 11:16:33 +0000

I created a stream with name sun in a chain wheree I am the owner/admin:

$ create stream sun '{"restrict":"write,read"}'

I got created.But when I try to subscribe to this stream it get following error:

This feature is only available in MultiChain Enterprise: Subscribing to read-restricted stream

And when I tried publishing, it gave me this error:

Publishing onchain items is not allowed to this stream

So, is there any way for admin/owner of the stream & chain to subscribe, read and write to this stream without opting for Enterprise edition?

Thanks!

New node can't read or write to chain even after given permissions

Wed, 27 Jun 2018 12:44:51 +0000

So basically I have a node who has valid permissions but is getting an error saying they have invalid permissions.

So first I created a new node like this:
^{multichaind myChainName@12.345.678.910:8080 -daemon}

I then got this message:
^{Please ask blockchain admin or user having activate permission to let you connect and/or transact:
multichain-cli myChainName grant MyNewNodeAddress connect
multichain-cli myChainName grant MyNewNodeAddress connect,send,receive}

I then granted connect,send,receive,create,admin permissions to the new node

then I ran:
^{multichaind myChainName@12.345.678.910:8080 -daemon}
again and it connected

But now this node cannot read any data on the blockchain or write any data

^{multichain-cli myChainName liststreams}
returns nothing (I have 5 or 6 streams on the chain)

^{multichain-cli myChainName create stream newStream true}
gives this error:
^{error code: -704
error message:
This wallet doesn't have keys with create permission}

^{multichain-cli myChainName listPermissions}
returns this:
^{[

Am I missing a step here or should that node be able to read and create streams?

Lock stream as if it were a TX

Tue, 29 Aug 2017 00:33:25 +0000

Lets say I have this stream with have 1 owner (write permission) (A)

Then I want to "transfer ownership" to a new owner and lock write permissions only to new owner.

I was thinking if there is a way to do it like a normal transaction signing input/output.

Is there any way to achieve this?

A single admin cannot grant mine permission with admin-consensus-mine=0.5

Fri, 11 Mar 2016 12:38:09 +0000

Greetings,

I have initialised the chain with admin-consensus-mine=0.5 and created one additional node without admin, activate or mine permission. That means that I have a single admin. I tried to grant mine to the second node, but it puts it only into the pending permission, although the one and only admin tried to grant the permission:

zolichain1: listpermissions mine * true

{"method":"listpermissions","params":["mine","*",true],"id":1,"chain_name":"zolichain1"}

[

    {

        "address" : "1QhdwmVrxCRnS7r6vFuvLSiKQ53FqQ5MvEqk93",

        "type" : "mine",

        "startblock" : 0,

        "endblock" : 0,

        "admins" : [

        ],

        "pending" : [

            {

                "startblock" : 0,

                "endblock" : 4294967295,

                "admins" : [

                    "1TFvWaHMkbBUnfGyXJZgtxCmMHmqMytiPz24Lm"

                ],

                "required" : 1

            }

        ]

    },

    {

        "address" : "1TFvWaHMkbBUnfGyXJZgtxCmMHmqMytiPz24Lm",

        "type" : "mine",

        "startblock" : 0,

        "endblock" : 4294967295,

        "admins" : [

            "1TFvWaHMkbBUnfGyXJZgtxCmMHmqMytiPz24Lm"

        ],

        "pending" : [

        ]

    }

]

Why isn't it granted? The required is set to 1 and 1 admin requested it.

Many thanks in advance,

Zoltan

As you can see, that spending transaction is marked as complete, however when I execute the last command I receive and error: {"code":-25,"message":""}

I think the last command fails because the multisig address does not have send permission. Also to be able to send the first (funding) transaction, I had to grant receive permission to the multisig address.

I have more problems with this:

Why the created multisig address does not have send, receive permission by default?

I cannot grant the multisig address send permission due to an error:

{"code":-4,"message":"Error: The transaction was rejected: 64: Permission script rejected - only receive permission can be set for P2SH"}

Can you help me with this?
