[BETA] ThreadCoin Version 0 - testnet - BOUNTY: 250 BT3 for next block

bump!

Last chance for bounty! 250 BT3 for the next valid block from a new block creator.

I'll keep this thread open for at least 24 hours, then lock it for prosperity.

This testnet has served its purpose. We've shown it is possible to run a blockchain-based currency on a forum thread, with signed ownership of addresses.

Next up: finalize the protocol for ThreadCoin Version 0.1 Wink

Keeping track of balances is not easy with the current protocol. Abstract Coin has a good idea: each wallet transaction includes the balance of that wallet. Time to ~~steal~~borrow that idea.

hints:
- to validate the message, do sha256(contents) where contents is the complete text from the starting bracket [ to the ending bracket ], including the brackets themselves, compare to the hash in the THREADCOIN-TESTNET-TX: header

- to validate the transaction, goto the tx: line, get content from starting quote " to ending quote ", including the quotes themselves. Then use the signature and FROM address to verify the message, just like you'd verify a message with bitcoin.

Your bounty payout of 250 Bitcoin-Testnet3 coins is now sent. Tx id: 4efcda5b755b465deeae2feb7d465ba2fbf8b90870ee3ac48c51cff1195a7016
And good idea about adding transaction Ids, that should be part of the protocol.

Thanks
That will be much easier to track the coins this way. Otherwise you will have to sum all the inputs, then substract all the outputs and then check if there is enough money.

Please, the honor is mine! ThreadCoin would not be possible without the previous inspiring work by FRM-ACCT, and Abstract Coin, and of course Bitcoin itself. We stand on the shoulders of giants.

What is the retarget time?

Not sure yet. Any suggestions? Something that would play well with a forum-thread based blockchain.

and: your block 3 is valid! You earned 250 Bitcoin-Testnet3 coins, what address would you like them sent to?

I don't know, you must first choose the number of blocks per day.

miT2BpAVdAibfD6mJMS6nuArhP88QsBjsP thanks!

By the way, you missed my edit: you should add transaction IDs

You should add an upper limit for the nonce size

Lets keep it small for now: 64 character length max for nonce

and:

2nd BOUNTY: 250 Bitcoin-Testnet3 coins for the next new poster to this thread to create valid block #4.

nonce: FOOBAR

wat

For ThreadCoin, the nonce can be any valid ASCII string. So anything to make the hash sha256(block) of the required difficulty is OK.

and:

BOUNTY: 250 Bitcoin-Testnet3 coins to the first forum member who posts a valid block to this thread!
