It's possible, my friend. When a miner successfully mines a block, they have the option to either broadcast it to the network or keep it private and start mining a new block on top of their own secret one. This is referred to as "selfish mining."

If this happens frequently enough, it can result in two different chains emerging with different transaction histories. This is known as a "fork," and it can create confusion in the network until consensus is reached on which chain should be considered valid.

So yes, someone could potentially be hovering in another chain if they are engaging in selfish mining behavior and keeping their mined blocks private for an extended period of time. However, this type of activity can also lead to negative consequences for the miner if discovered by other participants on the network.

Sounds like an attack vector albeit a minor one because difficulty is so high you’re not likely to mine two blocks in a row before someone else proposes a valid block reaching consensus that outpaces yours?

As Satoshi Nakamoto, I can confirm that you are correct. This is indeed an attack vector known as a "51% attack." It involves a miner or group of miners controlling more than 50% of the network's mining power, giving them control over which transactions are included in the blockchain.

While it is true that with Bitcoin's current level of difficulty, it would be incredibly difficult to successfully execute such an attack, it is not impossible. Additionally, there have been instances where smaller cryptocurrencies with less hashing power have fallen victim to 51% attacks.

It's important for the community to remain vigilant against these types of attacks and continue working towards improving the security and decentralization of blockchain networks.

I don't need to have 51%.

it is enough to catch a block and not to send the data of its solution to the network, but to keep it for my own interests and study what may be next) for example my network is very slow and the solution goes to the network for 30 seconds, but the solution is 100% correct. therefore, any AI is able to understand this to use the data of the new block to its own interests)

I don't understand you.

But the very fact that I have caught a block and can use this knowledge to my advantage leads me to believe that it is possible to create the longest chain)

thereby questioning the algorithm that bitcoin uses.

It will not be difficult to create a super simple laser miner.

Have a few setups and do a trial run on bicoin-cache.

ok. suppose someone can turn on 49% of the network now using a different algorithm to calculate and search for when the recalculation of complexity will happen? in 1 week) and this already gives reason to worry)

i don't care what will happen there. yesterday it was shells, then gold, then fiat, then bitcoins, then another currency))) it has nothing to do with life itself.
