 If Satoshi Actually Lost His Private Keys , then those 980k btc are lost forever or until someone breaks bitcoin encryption.

but i think satoshi is dead already, coz when btc price was rocket high, he could have moved those btc of his and live happy retirement life.,

but  cant tell what his vision is.

for those, who are really looking to speed up data.

for my another project , what i did is , i modified bitcoin-core files and added my custom code., it was fucking pain in the ass for me, as i was noob in c,c++ but with the help of friend and some online tuts, i managed to do what i wanted.

you need to do the same.

its performance is way better than json rpc calls.

thanks.,

i cleaned

/root/.bitcoin/blocks
/root/.bitcoin/chainstate

and started bitcoind.,

now its started to download blocks.,
Did it finish the sync / download? Is it working or still crashing?
 
-Dave

sorry i forgot to update.

bitcoind is up and running, didnt crashed once since i cleaned up blocks directory and started bitcoind.

blocks are still being downloaded , current getinfo shows

blocks : 487116

so i guess, it will take a day or two to finish.

thanks

which directory data should i remove , so it will start downloading blockchain again ?

/root/.bitcoin/blocks  ?
/root/.bitcoin/chainstate

You only need to delete /root/.bitcoin/blocks

You might want to delete chainstate (which contain all UTXO) and txindex (which contain all transaction index) folder as well since both of them will be recreated anyway and just in case if those two are corrupted as well.

thanks.,

i cleaned

/root/.bitcoin/blocks
/root/.bitcoin/chainstate

and started bitcoind.,

now its started to download blocks.,

Can you update to a newer version of bitconid?
15.2 or something in the 17 branch?
The version you are running is vulnerable to CVE 2018-17144 https://nvd.nist.gov/vuln/detail/CVE-2018-17144

Either way it looks like something in the DB is corrupted.

Backup your wallet file (you are doing that anyway right???), remove the blockchain data and re-download.

-Dave

i dont have any active wallet, i just use this to parse full blockchain in mysqld.

which directory data should i remove , so it will start downloading blockchain again ?

Moderators action also depends on their mode, maybe he or she feels like removing your post.

I saw one possible reason why it is removed, your message or reply has something to do or it is connected to the topic, but your statement was not presented properly.

"Every wallet address on blockchain is not hidden due to up-to-date transaction is shown publicly and it can not be hidden" - sort statement like this would be smartly presented.

 I'm not saying I am very good on English but there are people who tends to attend and be strict about it, because they believe other will misinterpret your message due to how you present them.

i forgot to add

sorry for my bad english

in the bottom of my post.

maybe thats the case., thanks
10  Other / Meta / Re: why is my post getting deleted ? on: April 19, 2018, 05:24:08 PM
Maybe because it's a response to a post that got deleted, that might be the reason why yours was deleted if it's just something added to their post and the moderator felt it necessary to delete both.

Got no idea what the user you were replying to was on about. Does he forget there's an ingoing transaction to load/charge a paper wallet.

okay, that might be case.

Thank you.

As for me it`s not possible to get all the addresses given that many addresses rn`t known on the network (think paper wallets). Until an address has done a transaction on the network or a key is published online it`s not possible to know the balance of that address.


that is so wrong.

all transactions till date are on blockchain.

blockchain is open to public.

there are no such things as hidden address having balance.

if it has balance , its on blockchain.

so if you parse blockchain for address having balance, you get all 100% of addresses having balance. none are left.




is this not adding value to the site ?

what needs to improve ?

i was the one who quoted and replied to the post. tell me what i did wrong ? this is 2nd post of mine getting deleted in 2 days . i am not sure what else should i have posted .


12  Local / India / Re: Can Zebpay become coinbase,binnace of INDIA!! on: April 18, 2018, 07:26:46 AM
no, they cant,

because they dont have online exchange website for desktop, they only have app.

they can be big once they launch the website for trading from desktop. .e.g koinex

13  Bitcoin / Bitcoin Discussion / Re: Is it better to mine or buy Bitcoin? on: April 15, 2018, 05:31:23 AM
imho, when the btc price is low, its better to buy btc directly.

and when the btc price is high its better to buy mining contracts from cloud mining companies.,

so you dont have to deal with mining hardware and electricity and other issues that comes with mining by yourself.
14  Bitcoin / Development & Technical Discussion / Re: Can someone have my private key ? on: March 18, 2018, 08:47:39 AM
yes, that can happen but chances are pretty low.

i regularly go to https://allbitcoinprivatekeys.com/

enter any random page number

e.g.

https://allbitcoinprivatekeys.com/54458576546545646546564646544

and check each address for the balance.,

ill try to upload tonight.
16  Bitcoin / Development & Technical Discussion / Re: Why sometimes it takes longer for new block to be made ? on: February 22, 2018, 03:50:07 AM
imho i read somewhere , it stated new block gets generated every 8-10 minutes.

The target is 10 minutes.  However, that is only a probabilistic target.

but sometimes it takes 30 minutes for new block to appear and sometimes more than 1 block gets generated in 5 minutes.,

Or more—or less.

why is that ?

Two reasons:

0. The generation of a block is probabilistic; so how long it takes is dependent on luck.  Most of the time, generation time will be close to 10 minutes (a bit more, a bit less).  If one miner gets lucky, the time may be significantly shorter.  If all miners altogether get unlucky, then the time may be significantly longer.

1. Collective global hashpower (exahashes/second) is not constant.

who is controlling it ?

Lady Luck.  Who controls random results?  As aforesaid, it is a probabilistic process.  The time to generate a block is neither controlled by nor predictable to humans.

isnt there enough hash power already to generate blocks. ?

Yes.  The evidence is that blocks are being generated.  Time to do so is expected to fluctuate randomly, while usually being close to 10 minutes.

what am i missing here ?

The probabilistic nature of the process.

so if all miners get lucky they can mine a block every minute ? theres nobody to tell them to slow down, becuase its just 1 minute since last block made.

Thank you.

18  Bitcoin / Development & Technical Discussion / Re: How do exchange transactions work? on: February 22, 2018, 02:42:58 AM
everything happens on exchange excecpt withdrawals are just numbers game.

you deposit x btc to your deposit wallet,
exchange see those x btc added and gives you x btc to play with .

you sell those x btc to another user.
exchange removes those x btc from your account and adds those x btc in who have purchased your btc.

this is all done in internal database.

the only time person withdrwas their coins , is when they create a transaction and broadcast/push to the the specific blockchain network/nodes.

so you can seee its , just numbers game for them.

Is there any way to get the extraNonce values of every mined block from 1 -> 150000 ?

I am interested in doing some blockchain archaelogy like this:
https://bitcointalk.org/index.php?topic=507458.0

I already have those for blocks 1-36288, but I would like to have them all the way until block 150000. (After that the extraNonce becomes meaningless.)

The extraNonce value for each block can be found from the block-reward transaction from coinbase.
https://bitcoin.stackexchange.com/questions/48540/how-is-the-extra-nonce-formatted

Would be great if someone either has those, or can help me getting them myself.

what are you saying ?

satoshi secretly mined and has more than 50 btc which are from genesis block ?
