51%

[bracek]

can this be done to avoid 51% attack ?

miners who discovered new block only get reward and tx fees,
but actual writing of transactions and verification
is done by some other miner ?

no.

[bracek]

miners of recent blocks would be randomly eligible to "write"
transactions in the next block

sounds ok

[kokjo]

you cant write something in a block, without changing it.

please stop asking questions that shows that you know nothing about how stuff work.
go read some more and find out why you are failing.

Bracek keep the decentralized approach in mind!
As soon as one entity gathers more than half the crop the thing is no longer decentralized, thus consider it broken.

I think you both did not get what I wanted to say
I am not preaching for any kind of centralization

I just asked is it possible that miners switch their duties
of writing current transactions in newly mined block

miner A mines new hash
broadcasts that he found it

then miner B is is chosen at random
he will use this new found hash to create a block

miner A gets his reward and fees

in the long run, there is no extra unpaid work,
just the miner with most hashing power would not be able to write latest blocks

if again, i got it wrong, I won't post here any more

The hash is ONLY valid for a specific set of inputs (Version   Block, Previous hash, Merkle root, Timestamp, Target/Difficulty, & Nonce)
You create a block header containing the above information and hash it.  If it meets the target you found a block.  If it doesn't you change one value (usually nonce) and try again.. and again ... and again on average it takes difficutly * 2^32 hashes to find one which meets the target.

https://en.bitcoin.it/wiki/Block_hashing_algorithm

You can't find a hash and then make a block out of it because the hash is only good for the EXACT blockheader.  One element of the blockheader is the merkle root which is a hash of all tx in the merkle tree.  If you could change the tx and get the same merkle tree hash well then Bitcoin would be worthless.

If you change one thing (even one bit of tx) the block will have a new hash for a given nonce.

how do you distinguish between different miners?
how do you choose at random in a anonymous possible hostile distributed system?
do you really think that miners would pause the generating blocks, just because he/she/they found one,

and oh btw. miners just don't create blocks, they try millions(and more) different ones to find one that "fits".

your posts shows lack of knowledge, please go read some more.

-1, no he should be in the newbie forum, not in the technical forum.
i would have(maybe...) been more polite to him in the newbie forum, but he thinks he know something he does not.
he is not seeking knowledge, or asks to gets something to be explained to him. NO! he suggests something stupid, without knowing how stuff works(or even wants to know, judging by his posts). Thats why i kicked his balls... and NO! you can not make me feel bad about doing it, by giving me a "-1", or making fun of my superiorness.
