It allows the network to organically develop exchange rates rather than being trolled by wall traders. And if we add a time parameter to the exchange then it’s not this panic market where everyone waits for the market to react.

Go onnnn.

This will seem overdone, but it’s enough to cause headaches for rogues and eavesdroppers and it encourages lots of miners to negotiate with each other which will be enough support for even more wild exchange ideas.

[b]8. TRADE SETUP[/b]
Coin trader A moves complete amount they want to exchange to their outgoing address.
RULES:

They are still in possession of it.

Trader A locks their outgoing address.
RULES:

No exchanges may occur from addresses which have no locked address in their trade history.
No locked address may be unlocked until the correct number of spends occurs on the virtual trickle address.
No exchanges may occur which are not matched.
During lock coins may only be sent to virtual trickle address.

Trader B does the same as above and Trader A as below

[b]9. TRADE CONTRACT[/b]
Trader B specifies a lock threshold.
RULES:

Trader A may unlock their address after the number of trades X trade difficulty is greater than the threshold
Trader A may unlock their address after the confirmations for the last spend is more than the threshold.

Trader A moves portion from outgoing address to virtual trickle address.
RULES:

The virtual trickle address is only valid when:
a. The amount remaining in the locked address is equal to the amount encoded in the virtual address.
b. The relative diff rate (trade diff divided by the mining diff) is greater than the threshold times the trickle rate.

[b]10. PRIVATE KEY EXCHANGE[/b]
Keys and pads are exchanged randomly like this:
RULES:

Trader or Miner P sends pad A XOR pad B XOR pad C to Miner Q = A x B x C
Trader or Miner P sends private key XOR pad A XOR pad B to Miner R = priv x A x B
Trader or Miner P sends public key XOR pad B XOR pad C to Miner S = pub x B x C
Trader or Miner P sends public key XOR private key XOR pad A to Miner T = pub x priv x A

Miners exchange secret combinations until they find both public and private keys with full trickle addresses.
RULES:

Even if private key is found consider it failure if address is empty
Q x R = priv x C
Q x S = pub x A
Q x T = pub x priv x B x C
R x S = pub x priv x A x C
R x T = pub x B
S x T = priv x A x B x C
Q x R x S = pub x priv x B
Q x R x T = pub x A x C
Q x S x T = priv
R x S x T = C
Q x R x S x T = A x B

[b]11. MINER MATCHING[/b]
Miners search for trades to match.
RULES:

The thresholds are close to each other
The trade diff divided by mining diff * trickle rate are close to each other
They line up in round robin fashion by closest match.
The number of miners is at least relative diff rate A / relative diff rate B and num of matches is at least square of num of miners

Miners exchange private keys with each other.
RULES:

Trades only occur in pairs:
a. Two miners have exchanged FLUX tokens weights representing the relative worth of the currencies
b. Coins have been sent to virtual trickle addresses.
c. The weights closely match the relative diff * trickle rate.
d. Trades involve not a lot more more nor less than the trickle rate.

Next: EXCHANGE CIRCUIT REWARDS (gotta reward the exchange miners)

Zero - can you explain this in layman’s terms?

Let’s say I have 500 LTC I want to trade for FTC. How do I do it? How do I set up a “sell” order? How is it verified? Is this even within these normal bounds of exchanges? Also - let me know if you need help with anything [logo + graphical].

Finally - Merry Christmas!

I’ve got another section to go but yeah I can give you a description:

You have 1000 LTC.
You move 500 LTC to an outgoing address.
You announce a virtual address which like Link contains data about the transfer.
You send a portion of the 500 to the virtual address.
A few miners notice the announcement.
They try to find matches for your details based on what the other coin is worth.
The miners send each other FLUX tokens in that have similar worth (relatively).
They then start trading with other miners for tiny amounts of LTC and FTC until they accumulate the amount you expected.
As they move coins out of the virtual address, they send coins to your incoming address.

The main idea is you are trading with the network rather than individuals.

But again this isn’t limited to coins. The amount of coin that is encoded in the address can instead be a file size. And you would purchase a file and the network would send it to you in pieces. Link + FLUX can be used for subscriptions, micropayments, and a whole lot of other things.

Shorter version:
You send coins.
The miners do a trial run using fluxtokens.
Then they do it for reals.
Only transactions already simulated are valid.

Thanks for this and the above longer explanation.

Two more questions:

1. Will I be able to set the price I want to buy/sell at? I guess it would be part of it - and miners match up buyers and sellers based on their price etc.
2. How is security handled [how are miners prevented from exploiting the system]?

You are not dealing with individuals, so prices don’t make sense. Instead you would set a kind of trading difficulty and you would get offers based on that. The real world is too slow and too panicky about prices. Global prices are bullshit. We’re not even going to interface with that. Instead your relative difficulty will say how much work you expect the exchange miners to do and prices will evolve around that eventually 'til they resemble traditional exchange prices.

Security comes from the same place as with the blockchain. The clients won’t accept trades that are not conforming to protocol. Also since miners are trading failed hash rewards, there is no incentive to sell the tokens.

All token transactions are exchanges, they always happen in pairs. I’ve thought about a way to upgrade those failed tokens to real coins, but it might not be wise to do that.

Incidentally, since we are talking about relative difficulties (the equivalent of exchange rates), this allows CPU miners to participate. The CPU coins out there are spending a lot of effort trying to restrict performance. I get the motivation, but with that much effort on one feature they won’t evolve fast enough to keep up with features people want.

A failed 4 token hash compared with a 1 token hash is 4:1. this is the same as an 8 token hash compared with a 2 token hash since the exchange is still 4:1.

So in layman’s, are we talking about trading with the network as opposed to users?

Instead of buying and selling crypto’s through exchanges or directly with other users, this will trade directly with the blockchain it self?

The network exchange miners will trade crumbs of the amounts you are putting on the market, so yes your BTC for FTC may come from many actual users.

This last bit of the concept is going to be vague and somewhat confusing, but in my head at least it’s done.

Actual protocol development is next.

Sketch of the final quarter.

[b]12. EXCHANGE REWARDS[/b]
Miners are rewarded for unique matches made.
RULES

Matches must be within a given window close to the exchange rate.
Matches must be at least a certain amount different from other matches.
Each unique match receives a signature.
Reward is divided among miners.

[b]13. EXCHANGE CIRCUITS[/b]
Miners negotiate exchange of coins through stages.
RULES

A circuit is formed when multiple miners are locked into the same trades over a long period.
When mining failed hashes the trading difficulty is averaged over the group.
Miners broadcast hashrate and expected income with proof.
Miners can accept or reject miner connections based on various details.

[b]14. PILOT TRADES[/b]
Miners trade FLUX tokens by relative difficulty.
RULES

Only the relative difficulty matters so CPUs can do it.
Trades can go through miners more than once but not sequentially.
Trades are proportional so it’s easy for amounts increase exponentially.
Once trades reach near coin traders the pathways are set.

[b]15. FLUX TOKEN GENERATION[/b]
Tokens are generated for failed hashes which are equivalent to the difficulty.
RULES

Low difficulty unrotated hashes reward anchor tokens of the low difficulty.
Hashes which are rotated X bits and are higher difficulty by 2X get rotated left by X/2 and lose half difficulty.
Rotated hashes which become equivalent to winning unrotated hashes but are longer by 4X of the rotation become real coins.
Low difficulty hashes which together are 2X longer than the average deficit from the minimum difficulty become 1 hash if there is an anchor hash.

I’m having a lot of trouble understanding this part.

I really feel like we need a very simple example. In the Link spec, I provided a breakdown of an actual link encoding, and broke it out by op code and function, denoting the purpose byte by byte. Can you put together an example Flux transaction, and break it down byte by byte as it would actually look in the blockchain?
