I exactly need slow Javascript Bitcoin miner's script
since I would like to watch if nonce is reset by Bitcoin node while looping.

Need to start in off-line mode ( input data from successfully hashed block of transaction)
to verify JS script and implemented sha256 script work smoothly not generating any bug.

Some declare nonce is reset at radom to generate extraNonce
but failed to access official documentation on nonce and extraNonce generated
if nonce range overflows and block hashing is still unsuccessfull ( hash is still above the preset target)

I would like to watch extraNonce charts generated locally
since with Bitcoin nodes supporting 1Th/s cloud miners,
a node can distribute, generate an already hashed block, since hashing is done real-time,
much faster than Bitcoin node lags.

So, in theory, a 1Th/s Bitcoin node can act as the fastest Bitcoin miner, releasing already hashed blocks
to specific hash addresses.

Let me know your opinion.

Does it bitcointalk is clocked every 360 secs ?
Login , wait 360 s
posted a message - wait 360 s
to start with search

search done , wait 360 s
to start with reading/ writing ?

Ok, if bitcointalk is clocked at 360 s intervals, no chance to implement "clock feature" warning
not to have post drafts deleted ?

Just waited 10+ mins ( well above 360 sec limit)
and system generated the same bug as before

"
The upper limit is 4294967295, but Bitcoin resets the nonce long before you reach that
"
Does it mean a 1Th/s Bitcoin node can distribute already hashed blocks to special users (success nonce discovered ) ?

Hello,

Any time I am trying to post this forum I get a number of posts deleted by a system before one post is accepted.
Is it done by system's bug or by default ?

Do I really have to wait 6 minutes to post a message ?
If so, just keep my post saved as a draft to not write it again from the scratch.

If you know a nice solutions to this problem please let me know.

How to discover the time my of last post and count 360 secs ?

Hi,

I am looking for Javascript for Windows XP  - Bitcoin miner
give me web link


Please explain me how a block of transactions is built
https://en.bitcoin.it/wiki/Block_hashing_algorithm

example
one transaction  - one to many ( to 100+ recipients)
http://blockexplorer.com/block/00000000000000033cb51d3b09710f8a983347b0b0adbe675290408627ed9831

I am interested in 1Th/s Asic miner
let me know details

Hi,

Looking for off-line Javascript bitcoin miner code.

Trying to develop one on my own unfortunately it looks complicated to build valid block header off-line.

Any idea ?

I run today Javascript sha-256 algorithm but looking for
fully developed   Bitcoin miner in Javascript for download to be run in off-line mode
I need input data from history of hashed blocks

(database of block headers)

Any idea, any help ?

Hi,

Could you help me implement Javascript block hash application ?

I have SHA-256 Javascript app and plan to use it for off-line bitcoin mining.

I am sure someone did it before ( bitcoin mining in Javascript)
so I could learn if my SHA-256 algorithm works properly.

Any idea about Bitcoin mining in Javascript ?

I have just built
Bitcoin R&D Labs
to develop faster header hashing solutions.

Trying to post I get
my post deleted

Hi,

I would like to learn more about Bitcoin's black hashing.

I have downloaded javascript implementation of sha256 fit to be run under Windows XP
http://www.movable-type.co.uk/scripts/sha256.html

I need to verify it against real data
and modify to accept new block of transations as input and  nonce as input
and hashed value as output in graphical form

I don't know how to get a new block what app run to hash Merkle tree to get single hashed value
as input into sha256 + time

Could you help me with basic, step by step manual ?

Hi,

please tell me what is a size of a block of transations and how to download a new and last one
to run sha256 hash and test nounces locally
and what app is ok to run such test

or just please give a web link to a new block of transactions.

thanks
darius

Hi,

looking for SHA256 how it works visual animation of the implementation, step by step

source comes from
http://csrc.nist.gov/publications/fips/fips180-2/fips180-2withchangenotice.pdf

http://en.wikipedia.org/wiki/File:SHA-2.svg

Could you explain symbolics of compression function  as defined

thanks
