Who is the Monarch?

As of 2017-05-25 20:40:29 UTC, the illustrious (but perhaps last?) Satoshi of BTC Kingdom was Satoshi Nakamoto, the most noble among men, possesor of a title respected even more than King, proud owner of a crown for which countless swords have crossed and for which blood has covered all the fields - how mighty is he, who sits in the Hall of Monarchs.

Important: This webpage is no longer being updated - the contract will continue to work on the blockchain but new rulers will NOT be listed here. Thank you to all the past Kings / Queens / Satoshis and for your interest in King of the Ether / Satoshi of BTC Kingdom.

How Can I Rule?

Important: This webpage is no longer being updated - the contract will continue to work on the blockchain but new rulers will NOT be listed here. For this reason we do NOT recommend sending funds to the contract, but we've left the instructions below just in case someone wants to usurp the last known ruler (even if no-one can see they have!) ...

FAQ

Where does the source code for the contract live?

github.com - KingOfTheEtherThrone.sol

What's the address of the contract?

The contract for Satoshi of BTC Kingdom is located at 0x267ac866397c4212ea7867789ba0af0a2dd74109.

Its Contract JSON Interface is:

You can watch it on a chain explorer if you like.

How much is the commission charge?

2%. This is shared equally between the top-wizard (the original creator of the first contract) and the sub-wizard (the creator of the individual kingdom).

Haven't I seen something like this before?

Yes, probably - there are/were a number of Bitcoin chain games along similar lines (though they normally seemed to involve owning a magnificent gem or a special coin).

The difference with Ethereum is that you don't have to trust the author not to run away with the money - instead, you can inspect the contract and rely on the blockchain to ensure it is executed as written.

This contract was somewhat inspired by ethereumpyramid.com (to which this contract is in no way affiliated or connected).

You might also be thinking of one of our Neighbouring Kingdoms.

Is this the first version of this contract? Or have there been other throne contracts?

This is the third version of the contract. Learn more about the past ages (including celebrity rulers!).

When a monarch is struck down by the curse, where does the money go?

Ah - I see what you mean, but it doesn't quite work like that - there isn't really any money to go anywhere when that happens! For example, if a monarch pays 15 ether to claim the throne from someone, then that 15 ether is not held by the contract - it is sent to the monarch before her as compensation (minus a little commission). So it's not like the 15 ether they paid is "lost" if the curse hits them - it had already gone to the ruler they usurped 7710 days 6 hours days earlier. The one exception is when someone claims an empty throne that's back at the starting price of 100 FINNEY (0.1 ETHER) - in that case it goes to the "wizards" behind the throne as commission.

I think something went wrong. Can I have my money back?

Ah. Well, you see, one downside of trustless autonomous contracts executing on the blockchain is that there is no possibility of human intervention - (almost) no-one can reach into the back of the machine and tweak things, even if they wanted to. Besides, there is no money to give back - it's all been given to the previous monarch, remember? So refunds are - regrettably - both impossible and unethical.

Is this safe? Or will we up with all the ether trapped in a DarkKingdom?

As the Disclaimer below points out, sending funds to experimental contracts using experimental wallets in experimental crypto-currency networks is probably not particularly safe.

However, we have put considerable effort into mitigating the risks - see our Contract Safety Checklist.

Disclaimer

This is intended as a bit of fun and to explore what a contract running on the Ethereum blockchain can do. Please don't spend money you can't afford to lose - keep it fun.

If you suspect that spending crypto-currencies on virtual thrones for non-existent kingdoms is illegal in your jurisdiction, please avoid participating (and complain to your political representatives).

Please note that while the contract will live as long as the Ethereum blockchain, no warranty is given that this website will continue to exist or will continue to promote the contract or list your name.

Under no circumstances will refunds or compensation be paid even if the contract steals all your money and/or shoots your dog. The author disclaims all liability for the operation of the contract which should be considered its own autonomous entity as far as permitted by law - it is your responsiblity to study its likely behaviour before interacting with it, including taking into account that the actual behaviour of the compiled EVM bytecode in a real eth/geth node may differ from the assumed behaviour based on the apparent intent of the solidity source code.

By interacting with the contract you agree to accept the conditions in this section as well as those listed at ethereum.org/agreement.
