In the above URL, fee needs to be feeNQT. And to avoid problems with special characters in secret phrase having to be encoded, use a form such as: https://localhost:7876/test?requestType=leaseBalance

The easy way to do it (it works on the test net, so I guess it will work on the main net too):
1. launch your client
2. open http://localhost:7876 (or https://localhost:7876 or whatever)
3. click "more info" on the square showing your account balance
4. click the "Account Leasing" tab
5. click "lease your balance to another account"
6. insert the account you wish to lease your balance to. Set for how long under "period" (it is expressed in blocks, so 1440 blocks = 24h) and finally set your secret phrase.
7. click the "lease balance" button.

How does that work?

Essentially he sets up an account. People lease their forging power to that account. What this means for you:
1. You do not need to leave your client open 24/7 in order to forge. He will. (truth be told, it is better if you still do for the sake of the network)
2. If you have small amounts of NXT, it is hard to compete (in terms of chance of generating a block) with accounts that own huge amounts of NXT. Account leasing allows "small fishes" to gain more relevance. Of course that does not entirely solve your problem. If you have a few NXT, you will still get a low percentage of the fees gained by the pool since your contribution is small.
3. It is safer than before. There were already forging pools before, but you had to send them your money. This requires trust in the pool, since they can decide to keep the coins. With leased forging, you give them just your "forging power", the coins are still in your account.

Is there any login or registration needed?

I could be wrong, but I highly doubt that. The only interaction you really need with the pool depends on how the rewards are handled. I suppose the idea is that you will be able to request a payout by sending an arbitrary message.

Do I just lease it to you and you share the winnings of all accounts equally to the forging power they give you?

Yes, that is the idea. More people get together to have a higher chance of generating a block. If the pool manages to do so, he will accumulate the reward every user deserves proportionally to the forging power of each. This still requires an element of trust. Your leased balance will automatically get back when the leasing period ends. However, how to handle the forging rewards is entirely up to the pool manager, so you cannot be sure (at least not 100% sure) that the pool will pay you accordingly. (compare this to the trust you needed before, where you had to send them your money)

General leasing question: I have full access over my account and can make sendings/receive NXT?
My leased forging power is automatically adjusted to my balance?

The NXT do not leave your account. If you have 1000 NXT and you lease them. Then the pool will register this has your forging power. If you spend half of them, the amount leased will decrease accordingly on the pool's side. It is up to the pool to keep track how every account leasing they power to them is actually contributing at any given time.
Needless to say, if you lease your balance and you still decide to forge on your account, it will count only once.

Yes you still can sell your NXT. You do not break the lease, from the pool's perspective you were leasing X NXT for a while and then suddenly started leasing just an amount Y. The pool is supposed to track these variations when it calculates your contribution.

There is a bug where? I just tried it again on localhost with POST enforced, and didn't have any problems submitting a lease request with this form.

Thanks, quite clever how this is handled.

Looks good.

I will lease over my balance to the forging pool to try this out.

great! I will wait until this works and give you my forging power

the high-availability forging is currently working, as is the tracking of each leasor's balance as of each new block.  So hopefully we can get as many leasors as possible before AE release, as those are 1000 a pop.

I will follow this and probably add my Nxt to your forging pool.

Is there a way for me to query your effective balance?  Either through a client or a Block Explorer?

I have over +600k Nxt and though I hit blocks, 75% don't have fees.  I prefer to be forging with at least a few million Nxt so that I can get more consistent payouts.

Thanks FC.  This is really awesome.

if you use the getAccount API you will get the pools forging power returned as effectiveBalanceNXT, along with all the lessors

# ncli getAccount l 16485327922386980388

    balanceNQT: 2000500000000
    effectiveBalanceNXT: 495004
    lessors:
        7280542853324874741
        13578790447497894235

    publicKey: dfa7078530beb39097c1e8faa62a192020d25b558a51f3705192cc46bcd62a45
    unconfirmedBalanceNQT: 2000500000000

#
to get the pool account's, or any lessors' individual forging power, use getGuaranteedBalance API using 1440 as number of confirmations


# ncli getGuaranteedBalance l 16485327922386980388 1440

    guaranteedBalanceNQT: 2000400000000

note that those 2 APIs I just showed you are in the testnet, none of the leases the production pool 1460178482 has received in the main chain have matured through the 1440 blocks yet, so they dont even show up yet.  but you get the general idea.

There is a bug where? I just tried it again on localhost with POST enforced, and didn't have any problems submitting a lease request with this form.

i think i just replicated the problem.  it looks like in testnet maybe it works correctly?  I just tried it on production main net client 1.0.0 and got the POST required API response.  then I disabled POST and now instead of taking me to the form it just says
{"errorCode":3,"errorDescription":"\"period\" not specified"}

in testnet, my 1.0.0 testnet client just takes me to the form


ETA: nevermind, I see that the test? needs to stay as is, even in production net if you arent on testnet. sorry

It says:
