I am willing to pay {{new_o.stake}} {{coin_abb}} to whoever thinks that at block number {{new_o.t_block}} the difficulty will be {{(new_o.dir==0)?'above':'below'}} {{new_o.t_diff}}.
He will pay me {{new_o.price}} {{coin_abb}} if the difficulty at block number {{new_o.t_block}} was {{(new_o.dir==1)?'above':'below'}} or equel to {{new_o.t_diff}}.

*** target block may vary by 10 blocks at resolution time ***

service fee on resolution is 0.25%

no fee on cancellation

Awaiting Target Block

Resolved


Resolution Process

Decentralized :

contract owners 0.125%
public resolver 0.125%

in a time window of 10 blocks before and after the target block anyone can send a resolve command to the contract
the resolution difficulty will be the difficulty of that specific block


    Centralized :

contract owners 0.25%

In case no one from the public has resolved the contract in the provided time frame ( 20 blocks )
we ( the contact owners ) will resolve with the precise difficulty that was on the target block

Basic guide

Miner :

Assuming you are minning Eth every months with the current difficulty.
in {{guide.time_delta*2}} months you'll have {{guide.power *2 }} eth if the difficulty doesn't change.

Total income: {{(guide.power*2)}} eth.

Now, let's assume that after {{guide.time_delta}} months the difficulty rises by % making your mining power be {{guide.power*(100-guide.diff_up)/100}} eth .
At the end of {{guide.time_delta*2}} months you'll have {{(guide.power*((100-guide.diff_up)/100))+guide.power}} eth.

Total income: {{(guide.power+(guide.power*(100-guide.diff_up)/100))}} eth.
A loss of {{guide.power-(guide.power*(100-guide.diff_up)/100)}} eth.


to reduce your loss in such a situation you can decentralizly lock eth for {{guide.time_delta}} months in the diff dapp contract and ask back eth.

If difficulty rises after {{guide.time_delta}} months you get {{ guide.price+guide.stake}} eth ( lock + price ).
Total income: {{(guide.power+(guide.power*(100-guide.diff_up)/100)+guide.price)}} eth.
A loss of only {{(guide.power-(guide.power*(100-guide.diff_up)/100))-guide.price}} eth instead of {{guide.power-(guide.power*(100-guide.diff_up)/100)}} eth.

If difficulty does not rise after {{guide.time_delta}} months.
Total income: {{(guide.power*2)-guide.stake}} eth.
A loss of {{guide.stake}} eth ( the lock ).


You have succefully stabilized your eth mining for an anticipated future difficulty change.

HODLer :

Ico season is over
kitties are passe
whats there for a HODLER to do?

Why not decentralizly lock some ether in the diff dapp contract to gain a small interest on your hodlings?

Of course there is a small risk to lose it all.

the miner above offers a {{guide.stake/guide.price*100}} % on your ether in {{guide.time_delta}} months.
Open up your Black Scholes model and check if it's worth it.

Roadmap


α

functional mainnet prototype
done


β

add support for more coins
gas performance audit of contract
security audit of contract


γ

miner risk calculator based on Grain Price Hedging
graph visualization of data


δ

new implementation of difficulty contract using nipopow on a target non smart-contract blockchain ( i.e. bitcoin )
new implementation of difficulty contract using crypto-conditions on supported blockchains



Adding networks to metamask

Add a custom RPC to metamask with chain id * url
( make sure no spaces are at the beginning and end - metamask does not like spaces )

classic 61 * https://etc-geth.0xinfra.com
( Classic must be opened on different link : Classic )
ubiq     88 * https://rpc1.ubiqscan.io
( really metamask? i get 'invalid sender' )
