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.

CreateAbstractWallet(ACreformed|reformed);

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.

Hi all,

jackjack:
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.

fishy:
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.

and:
2nd Bounty still open, 250 Bitcoin-Testnet3 coins to the next forum member who posts a valid ThreadCoin block to this thread (previous block creators may still participate, but are not eligible for this bounty Wink

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.

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?

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!

hint: to verify a block, take the contents (everything from the starting [ bracket to the ending ] bracket, including the brackets), and do SHA256(contents), and verify it's the same hash as in the message header, and it meets the difficulty.

YOUR MESSAGE HERE - PM ME FOR PRICE

Looks like FRM-ACCT has been forked! Some of the alts have interesting changes, others may just be pump and dumps:

CCT-ACCT

BCF-ACCT

and probably a ton more alts to be found....

I have heard of fans burning out Grin

The cheapy USB fans sometimes don't last long.

You can run 1 (ONE) without a fan. But a fan won't hurt.

Unless anyone has heard of burnouts from running without a fan?

You could just keep the coins. Let them age for a while, like at least 1 year. You may be suprised at what they are worth then.

URL? Or is this just all your own pondering?
