The 184 billion BTC overflow bug is a reminder that even “immutable” code is only as trustworthy as its review process. The real miracle isn’t that a bug happened, but that Satoshi patched it in hours and the network agreed to roll back. Decentralization is great, but consensus is everything
Bitcoin (et al) is/are not fully decentralized in the sense that a core development team actively maintains and proposes changes, even minimal ones. While it's true that major updates require broad consensus and may be rejected by nodes if controversial, we should acknowledge that certain points of centralization exist, particularly around development and decision making. These often overlooked aspects now carry more financial consequences, especially as Bitcoin becomes more intertwined with regulated financial instruments and political power.
For example, now, many L2s around Bitcoin are fully depending , and influencing on a future change: enabling again the OP_CAT opcode [1].
One of the biggest points of failure I can see happening is self hosted node packaged software services like umbrel. Where they are just updating your node for you.
Yeah that's a great example. I think sometimes people take "code is law" too seriously, when it is clear to me the code is just a deterministic way to form a consensus that works 99% of the time and the other 1% you get forking.
Comsent by whom? In most "decentralized governance" projects I've heard about, all you need is for the holders of 51% of the tokens to agree, and the holders of the other 49% have no recourse but to leave.
No, that's completely different thing. Mining power only "decides" about the blocks in the blockchain. 51% is only relevant in the context of taking over the blockchain by 51% attack.
Software versions and updates require social / economic consensus and have nothing to do with mining power. Bitcoin is open-source protocol / software and everyone can use whichever version they like. But there's also economic incentives to use the most used version and to make sure that it will keep being the most used version, i.e. forks are bad and should be avoided, therefore it's in everyone's interest to reach consensus.
Yes, but I was talking about "decentralized leadership" in all the projects following Bitcoin, which often use 51% of stake instead of 51% of mining capacity, under the social theory that the biggest stakeholders will be the most invested in the outcome of the project.
Those with at least 51% of the sustained hash power can already redefine “Bitcoin” to be whatever they want… At any time whatsoever? (assuming they stay cohesive enough as a bloc)
That statement is a bit misleading. The damage an attacker can do through a 51% attack is much more limited than that. It allows an attacker to censor transactions or perform double spends, but it does not allow them to "redefine Bitcoin" (e.g. change consensus rules, arbitrarily reassign coins, etc.).
> ...until someone exploited a code defect and took the founders' money, then they re-write history and ignored the hypocrisy.
Not everybody agreed - and so the Ethereum Classic blockchain was created, causing all the problems that go hand in hand with having different, forked blockchains:
It’s based on a social consensus only, the rest (Nakamoto Consensus, PoW, longest chain, difficulty adjustment, block halving, artificial limited supply, decentralization, censorship-resistant P2P network, open source, etc.) is a combination of a Rube Goldberg machine & crypto bros LARPing.
There is a huge scientific merit of the algorithms for reaching a distributed consensus when not all participants can be trusted (including the fact that the Bitcoin paper uses game theory to give evidence why malicious entities attempting to create another fork will by the mere design of the algorithms have a hard time).
What is, of course, social consensus are some aspects about what it "socially" means that there exists this concrete consensus in the blockchain. By the design of the protocol and its data structures, there do exist boundaries concerning possible "social interpretations" of this consensus, but a lot of aspects are up to different interpretations.
Bitcoin is the OG Birkin Handbag. Valuable for the story. People compete to own a bit of it for that. You can create your own Bitcoin clone and own all of it! But no story, no value.
Bitcoin didn’t solved a forkability and finality problems. Blockchain (or more properly hashchain) is a linked list of hashpointers, and since anyone can create a hashpointer pointing to the head of the hashchain - it means anyone can fork it. And indeed Bitcoin was forked multiple times, and the solution to forks was almost always either centralized and/or social.
IMO PBFT consensus algos have a niche applications anyway, and not required for Electronic Cash implementation, only for decentralized and/or disintermediated Systems-of-Record, but that’s a complete opposite of bearer instruments like electronic cash.
> Yes, they existed a long time ago and aren't wasteful as a way to generate "value".
Can you give me a literature reference for such a result, because this claim surprises me.
Of course Merkle trees existed long before - but they are just "cryptographically signed data structures", and thus don't solve the distributed consensus problem.
Of course eCash existed long before - but it depended on some central authority.
Of course distributed consensus algorithms existed long before - but they depended on the fact that all participants are trustable.
Thus, in my opinion Satoshi Nakamoto indeed made a really important scientific contribution for a quite specific algorithmic problem.
Yes, but no. The Rube Goldberg of PoW isn't just for show, it's a protection from Sybil attack (not that it makes the economics of it any less of a disaster).
You cherry picked one thing from the list, and even there made a mistake.
In Bitcoin PoW used as a method for leader election of the node composing the list of validated transactions on the ledger (aka block), or even an empty list of transactions (aka Nakamoto-style Consensus).
But without all the Rube Goldbergian nonsense it’s simply an illegal/unlicensed lottery where the participants pay with electricity for the right to earn records on the longest chain (aka UTXO with mining block rewards).
How could it? PBFT is an algorithm, not a problem to be solved. Bitcoin is byzantine fault tolerant though.
> Bitcoin didn’t solved a forkability and finality problems.
There's no such thing as a "forkability problem" and Bitcoin solves finality through PoW.
> And indeed Bitcoin was forked multiple times, and the solution to forks was almost always either centralized and/or social.
That's wrong. The vast majority of forks are resolved algorithmically. There were only 2 or 3 unintentional hard forks in the early days that were due to bugs. This hasn't happened since 2013.
The only real "social" aspect of Bitcoin is what value people decide to assign to the coins.
I was at Bitcoin scene since 2011, I think that I can distinguish LARPing from the real thing. It's not me who created a dychotomy between fiat and crypto, between HODLers/coiners and noicoiners, between Traditional Finance and Crypro Finance, between CeFi and DeFi, between IPOs and ICOs, etc. Crypto always looked like a Pinoccio who want to become a "real boy".
> "it’s simply an illegal/unlicensed lottery"
yes, the PoW-based mining is litterally called a puzzle solving or a lottery. How do you call a game where everyone buys a ticket with electricity, but only one at a time wins a block reward?
> How could it? PBFT is an algorithm, not a problem to be solved. Bitcoin is byzantine fault tolerant though.
OK, BFT (not PBFT algo) is a class of problems with many proposed solutions, but none is good enough if you need scalability. Bitcoin is a partital solution under multiple constraints, even 1/3 of malicious nodes can undermine it. Internet backbone (BGP) should be trusted. Governments should allow it. etc.
> There's no such thing as a "forkability problem" and Bitcoin solves finality through PoW.
the on-chain Bitcoin transactions are never final. Everyone have their own heuristic how many blocks to count depending on the amount transacted. Protocol only defines how many blocks gamblers (miners) need to wait before they can spend their lottery winnings (block rewards).
> That's wrong. The vast majority of forks are resolved algorithmically. There were only 2 or 3 unintentional hard forks in the early days that were due to bugs. This hasn't happened since 2013.
There were many more than 2-3 both intentional and bugs, but why argue? Even 2-3 hard forks are enough to show that it's bad design. Forks should be impossible by design.
> The only real "social" aspect of Bitcoin is what value people decide to assign to the coins.
IMO there are many more social aspects here beside price discovery of UTXO records and social consensus. Bitcoin core governance, Mining centralization in China. Cypherpunks. LARPing.
I'm disappointed that the article doesn't point out that this is really a nice, round, negative 10 BTC if you work out the overflow (in satoshis).
> The rapid implementation of the patch was vital in keeping Bitcoin a viable cryptocurrency. 184 billion Bitcoin would have devalued the currency completely, leaving it at the mercy of the person holding the newly-minted Bitcoin.
It would have become worthless, sure, but I imagine that other people would have also just gone around creating additional batches of 184 billion BTC and driving the project into the ground, rather than letting one person walk off with effectively the entire thing.
Could all the large centralized mining pools (ghash and the like) plus exchanges like coinbase and binance blacklist or burn the 184B BTC? Didn't ethereum do something similar to revere a $600M "hack" a while ago?
I think it's US$21.7 trillion? That's now about 15% of the total global money supply.
So, it's good that the transaction was undone, or 15% of our planet would now be owned by some hacker.
(To be real: if they had not undone the transaction immediately, then the price of Bitcoin would have collapsed, and probably that would have been the end of Bitcoin)
>(To be real: if they had not undone the transaction immediately, then the price of Bitcoin would have collapsed, and probably that would have been the end of Bitcoin)
Yes, Bitcoin does not have sufficient trade volume, and it was a joke anyway. Bitcoin would probably not have survived even one more month in 2010, if there were 184 billion new "fake" bitcoins added in the mix.
Even ignoring all the problems about the Bitcoin software being proven to be seriously broken, those 184 billion extra bitcoins meant that every other Bitcoin was suddenly worth about $0.0000000000000001
The 184 billion BTC overflow bug is a reminder that even “immutable” code is only as trustworthy as its review process. The real miracle isn’t that a bug happened, but that Satoshi patched it in hours and the network agreed to roll back. Decentralization is great, but consensus is everything
As long as there's singular entity which leads the changes to the protocol, there's no decentralization.
Your critique is valid but outdated. This happened way back in 2010. Satoshi disappeared a long time ago now.
There are still influential people, but none with the authority of Satoshi himself.

Bitcoin can be forked, and in fact has been. You didn't mention mining centralization, which is another avenue.
One of the biggest points of failure I can see happening is self hosted node packaged software services like umbrel. Where they are just updating your node for you.
See also, the DAO hack.
Yeah that's a great example. I think sometimes people take "code is law" too seriously, when it is clear to me the code is just a deterministic way to form a consensus that works 99% of the time and the other 1% you get forking.
Leading doesn't mean coercion. Leadership in decentralization implies consent.
Comsent by whom? In most "decentralized governance" projects I've heard about, all you need is for the holders of 51% of the tokens to agree, and the holders of the other 49% have no recourse but to leave.
with bitcoin isn't it more about 51% of the compute rather than 51% of the token?
No, that's completely different thing. Mining power only "decides" about the blocks in the blockchain. 51% is only relevant in the context of taking over the blockchain by 51% attack.

It allows an attacker to censor transactions or perform double spends, but it does not allow them to "redefine Bitcoin" (e.g. change consensus rules, arbitrarily reassign coins, etc.).
51% hashing power doesn’t prevent forks. Including forks to 51% of the token systems.
That’s the thing people thing of crypto coins as math, but they’re still a social construct.
Just like the Ethereum fork in 2016 [0]. Before then, the battle cries of the crypto advocates were:
...until someone exploited a code defect and took the founders' money, then they re-write history and ignored the hypocrisy.[0]: https://en.wikipedia.org/wiki/The_DAO

In your private Bitcoin clone, such a consensus has a "socially much more boring" interpretation.
Nakamoto Consensus didn’t solved a secure scalable PBFT (Practical Byzantine Fault Tolerant) Consensus.
Bitcoin didn’t solved a forkability and finality problems. Blockchain (or more properly hashchain) is a linked list of hashpointers, and since anyone can create a hashpointer pointing to the head of the hashchain - it means anyone can fork it.

Seems someone missed the boat...
Nocoiners cannot understand Bitcoin?
Some do and have reasonable criticism, but you are just mixing up concepts and sound pretty bitter - hence my assumption.
show me at least one so-called "bitter" example from my posts
I have been researching crypto for over a decade. And I would be glad if I was corrected if I was wrong, instead of receiving personal remarks

At today’s price that’s … like … err more zeros than I’ve got fingers
I think it's US$21.7 trillion? That's now about 15% of the total global money supply.
So, it's good that the transaction was undone, or 15% of our planet would now be owned by some hacker.
(To be real: if they had not undone the transaction immediately, then the price of Bitcoin would have collapsed, and probably that would have been the end of Bitcoin)
At a certain scale, face value is meaningless and all that matters is liquidity.
$21tn in bitcoin isn't going to get you any more money than $1tn would.
(And maybe that wouldn't have been so bad)
>15% of our planet would now be owned by some hacker
why? It's not like btc has anywhere near the trade volume for 15% of global money supply.
