you can decode base58 to hex, and store the hex as binary.

i still dont get it., what do you mean by decode base58 to hex ?

do i have tp decode both WIF and bitcoin address ? and store as binary ?

what charset should i use ?

can i later search directly by using bitcoin address ?

thanks

you have an address, like 1QCkaDkCDAtsxG9LrLDbPrSne7q3hM3qm3 decode base58, you get: 00FE83D76016CF60187F978ACECB3480086BDD6443A1B813CA
you can store this hex (as binary) in mysql: https://dev.mysql.com/doc/refman/5.5/en/blob.html

okie, this is new., i am looking in to it,

thanks

looks like i can then decode WIF key too.

gee 9 challenages allready solved, people are smart and fast.

i hope you have basic knowledge of linux

first install

Code:

yum install git python pip

then you do

Code:

git clone https://github.com/petertodd/replace-by-fee-tools

then

Code:

cd replace-by-fee-tools

then

Code:

./bump-fee.py <txid>

e.g.

Code:

./bump-fee.py ac72df13e91b189f43b5cbe41f3f9f342391616bca553aafe04d219a665fced3

Code:

python bump-fee.py ac72df13e91b189f43b5cbe41f3f9f342391616bca553aafe04d219a665fced3

then i think, i think how can i make current idea better by checking already available projects on the same idea. and create new plan with improvements and add new feature and launch it.

p.s. dont share complete idea with anyone, just basic features.

remember you had the idea originally, so only you can make it better, not those who have stolen the idea.
but its also possible that 2 or more persons has the same idea. without knowing each other.

this is great find.,
looks like you can do transaction with 0 output and set the whole input as fee.

i need to know which collation in mysql is best to keep the size as low as possible so that the db size will be smaller and queries will be quicker.

i am currently using utf8_unicode_ci, but i read ascii stores more data in less space.

i want to lower db size so it can be fit in RAM.

so what are you guys using ?

thanks

Always remember blockchain.info is owned partly by Google. They invested $40,000,000 into it a few months ago. Any small issues like this are nothing to worry about. If it goes down permanently, I assure you it would cause huge turbulence in the community. Chances are it won't anytime soon... Tongue

I didn't read or even see this artilce's headline where you get this? Can you show us reference/source link saying this.

And to OP, you only have to wait or reload the page when it happens since blockchain do have some unexpected maintenance or you can't login due to this or even the same with your situation, so there's no need to worry just wait. Tho I didn't recemmend to use this kind of wallet because of this.

what i actually do is get the nodes list and try to add them in my node

i am working on a project where i need to scrape a site, and that site/cloudflare keeps banning my server IP addresses.

so i am looking to buy and use proxy servers ,

but i don't want limited servers e.g. 10 servers for 10 bucks per month.

i want service/site which offers 100s of proxy servers for fixed price like 10 bucks. per month

so what you guys are using ?

thanks.

there are many sites selling proxy servers , but i want some reputable and dont need VPN, as i need to connect to them using php script using curl.

I can try to bypass cloudflare and give you the original IP of the website. PM me for more info.

p.m. sent.

thanks

Sometime I used this site https://proxy.insorg.org/
You can try it. But if you will do legal things.
Don't really clear what you doing, so read their rules first.
The price is 10$ for month as you are searching.
You can pay via bitcoin.

thank looking in to it., site looks russian.

Blockchain.info crashes sometimes due to heavy load or DDoS, nothing to worry about, it goes back up in minutes

its been like that from last few days.,
anyways ill wait.

https://blockchain.info/connected-nodes

shows

Total Connected: 0

why is that ?

but i do see new unconfirmed trasnactions in

https://blockchain.info/unconfirmed-transactions?format=json

i am asking this because i am watching transactions using their websocket.

anybody from blockchain.info around ?

thanks for your time.

edit1:
looks like its been happened before.,

Why would it take 2-3 weeks to build???

Simply because i am a student and I have to build it only in my spare time

then you have to work harder and and smarter.
2-3 weeks time is too much. let alone 1 week.
whats stopping for person to go directly in the compuetr shop and buy all the parts and get it done from the store.

strange , did you try their support email or even phone number, try contcting them directly.,

i n ver had such issue, but i never used forget my password.

maybe its their way of protecting you from hack attempets.
but imho its poor practice.

i even mailed them to allow lower than 1k transactions to buy btc .

while starting bitcoind pass reindex parameter.
it will reindex the available blockchain files.

ref: https://bitcoin.stackexchange.com/questions/22199/what-exactly-did-bitcoin-qt-rescan-reindex-do

idk why would they spend that much energy to catch him ?

its not like he is terrorist or something., he is inventor of btc, yes, but what harm have btc done to society ?

i call bs on that article.

i have the same question, becuase its not easier to pay small amount without paying same amount in fees.
so gone ar the days paying for coffee using bitcoins.
