1  Bitcoin / Bitcoin Discussion / Very high fees - bitcoin fails on: February 27, 2021, 02:48:30 AM
After over 10 years of BTC, developers did not manage to make BTC scale.
Wtf is up with current high fees?
This sucks. Good bye.

It was a BTC transaction. Yes, i think fees are too high nevertheless. This needs to be worked on.
Thanks for the recommendations!

edit: sorry I wish i could merit all you guys!

Hi!

I just wanted to use bitcoin.com wallet for android and it warned me because of high transaction fees (around 20 $).
I cancelled and started a new transaction and it did not warn me again (around 8$).
This was maybe 30 seconds apart and I have no idea what to think about this but is this maybe a cheap way to advertise BCH?

If yes I want to switch software of course. Which software for android is trustworthy?

Thx for all recommendations!

Reagards!

Code:
const hdkey = HDkey.fromMasterSeed(seed)

const addrnode = hdkey.derive("m/44'/0'/0'/0")

console.log("\x1b[32m%s\x1b[0m",'PRIVATE EXTENDED : ', addrnode.privateExtendedKey)

const child = addrnode.derive("m/0");
const step1 = child._publicKey

console.log("\x1b[32m%s\x1b[0m",'PUBLIC EXTENDED : ', step1.toString('hex'))

//SHA256 of the public key
const step2 = createHash('sha256').update(step1).digest()

// RIPEDMD-160 of the SHA256 Hash
const step3 = createHash('rmd160').update(step2).digest()

// He we must add the network byte in front of that RIPEDMD result
// 0x00 for mainnet and 0x6f for testnet
var step4 = Buffer.allocUnsafe(21)
step4.writeUInt8(0x00, 0)
step3.copy(step4, 1)

// Return the bitcoins address
var step9 = bs58check.encode(step4)


resolve(step9)


The additional steps are already handled by base58check.

Honest remark: Be careful to understand and test everything before you release a product or better let professionals with much experience take care of this as there are many fragile aspects to this kind of code and people might lose real money when there are bugs.

Code:
 echo -n "0250863ad64a87ae8a2fe83c1af1a8403cb53f53e486d8511dad8a04887e5b2352" | xxd -r -p | sha256sum
sha256sum needs the bytes not the ascii representation of the hex-encoded, compressed public key.
xxd takes care of the conversion and should come with vim package in case you don't have it yet.

what does the letter B mean? Appeared a day later
It's only a text artifact because of the previously longer line [2.0/4.0MB].
Why are you searching this address?
