btcrecover VS bips

This would be quickly crackable using something like btcrecover. (https://github.com/gurnec/btcrecover)

For some ideas see this script: https://github.com/gurnec/btcrecover/

Try to use this software on GitHub https://github.com/gurnec/btcrecover - 922 stars, it's good - there is also a tutorial on how to recover a lost password from a wallet.dat file. 6 characters should be fast to find with a good GPU.

Perhaps not possible or at least a few years on a modern pc. Checkout btcrecover https://github.com/gurnec/btcrecover do some test runs with a known seed missing 2 words, then 3 words before your 4.

The hacker can use the 24 words to recover the wallet. If there's nothing in it, he might give up, or he might guess that there's a passphrase. Then he hires a private investigator to discover your private details - schools, pets, uncles, birthdays, anniversary dates ... - and he configures https://github.com/gurnec/btcrecover with these details. If you're like most people, your idea of a secure passphrase can be guessed using 30 minutes to 10 days of brute force

This code can compute multiple combinations: https://github.com/gurnec/btcrecover - Last time I used it I found it hard to setup and I guess today it'll be even harder.

use a brute forcer approach like btcrecover. note that the learning curve is pretty up there though. every little characteristic you can remember about your passphrase can help speed up the process (number of characters, lower case or upper case, digits, positions of these characters, list of characters to use, etc.)

Modern bitcoin addresses use a base-32 character set that leaves out some of the most ambiguous pairs and also permutes the address ordering so that the most visually similar remaining characters produce single bit errors which are better handled by the addresses error detecting (and potentially correcting) code.

Context: Bitcoin miners have just adopted a 50% pay cut for themselves. This pay cut was baked into Bitcoin protocol at the launch of the network (mostly, see "BIP 42" [1]). The OP link gives information about the block in which this pay cut was made.

I get that HN comments tend to dismiss Bitcoin. But the fact that for the fourth time this pay cut has happened without a hitch speaks volumes to what makes Bitcoin interesting: It's a rare combination of economic incentives and technology that keeps chugging. Nobody can stop it. And it's extremely resistant to change. It requires no governmental approval. All attempts at subversion or interference have failed. There aren't many things that come close to that kind of record.

Bitcoin transactions involve locking funds in scripts, which can only be spent if those locking conditions are met. The part of the script that expresses these locking conditions are called ScriptPubKeys. On the other hand, the part that provides unlocking scripts to satisfy the locking conditions is referred to as ScriptSig for legacy transactions, and ScriptWitness for SegWit Transactions. These scripts are evaluated by a stack-based language called Script. This article will mainly focus on ScriptPubKeys.

There are 5 271 537 971 301 488 476 000 309 317 528 177 868 800 possible permutations of the bip39 wordlist found here: https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt when using 12 word seeds. You probably have better change to win the lottery every week for the rest of your life than cracking a 12 word seed in correct order

No one controls Bitcoin, because it's a protocol. Bitcoin Core is the reference implementation, but there are others, and anyone can create new implementations if they wish. Also, the Bitcoin Core maintainers can't just change something on a whim, because users would then switch to another fork. Maintainers (or miners or other groups) can't force their changes on users, because everyone can decide on their own which version they want to use.

The protocol development happens through BIPs (Bitcoin improvement proposals): https://github.com/bitcoin/bips

BIPs are discussed for years, before (and if) they are implemented, and basically everyone needs to agree on them, because no one wants to fork the blockchain, which could be devastating.

All the seeds generated from the CoolWallet (Number / Word) adhere to the BIP-39 protocol.
