Well, if you don't need global knowledge I think something closer to
2PC protocol design would be better. More scalable and private, but
with its own limitations. Without a cash host currency.
If you don't need global knowlegde, don't start with this consensus
algorithm because that's what it solves.

There is no need for fees in the ledger. No global knowledge,local.

The reason I stop is because someone has to write the code, otherwise this
is useless.
I am currently working on something else, so It is not up to me. Others
need to chip in.

Is lying to the whole network if she gets a free transaction into the ledger.
If Alice pays Bob, Bob can be certain that Alice has paid to someone.
But if Alice pays Carol, Bob has no way to be sure that Alice and
Carol aren't the same person and therefore Alice hasn't really paid to
anyone.

Anyway, this discussion serves no purpose. If people really want to find
solutions, they will.

It is up to the community if it wants to defend ripple's vision for social
change.
I dont have anything else to say.

If Bob gives fees to Alice , does Bob care if Alice gives fees to herself?
Does Bob care if Alice is lying to herself?
Bob doesn't know what Alice is doing and doesn't care.
Isnt this the way ripple work?

You said we would leave that for later. If it can't work with xrp, it
can't work with IOUs.
I've been re-watching the video several times with your suggestion in
mind: [link]

The first thing I realized is that fees can't be propagated, because
the transaction would be different in each propagation path and you

Servers could even have credit balances between themselves like in Ripple.
They could thus send credit tokens in the gossip protocol.
Then one server would transfer money to the other if and only if the
traffic from one server is bigger than the other.

I hadn't thought about this.
Let me see if I understand you. A users gives the transaction to a
server, who gets a proportion of the fee, the nodes in his UNL get
another proportion, the nodes of the nodes...
For a pre-defined number of steps to consume all the fee.

It's an interesting suggestion, but I need to think more deeply about

Re: [Ripple] a question for opencoin

Have you then thought of a fee that propagates through that gossip protocol?

In ripple, we trust a small number of people, but we are able to transact
with people we dont know, right?

Do we need to know ALL nodes to give them fees?

As far as I know, there's not a list of all the nodes participating in
the consensus anywhere.
Each node has its own list of trusted nodes (UNL) and that's what
connects them in one single network.
The rules are designed so that a consensus is achieved rapidly even if
the topology of the network is not known by the individual peers. The

The trusted list is the list that takes part in the ledger. When a server
participates in the consensus of the ledger he receives a fee.
If someone wants to spam the network , he has to pay.

xrp can even be credit, dont worry about this for the moment.

If each user can chose its list of trusted servers, my two attacking
users are in a server I control so again I pay to myself and spam the
network.
If the list is the same for all users, you're introducing centralization.

The xrp fees in the current system are destroyed, not given to people
you don't know.
