No company, no government, and no platform controls Bitcoin. Bitstack lets you buy, sell, and hold bitcoin, but the Bitcoin network itself operates entirely independently.
A network without a center
Bitcoin runs on a decentralized network of thousands of computers around the world, called nodes.
Each node:
runs the Bitcoin software, which is freely available to anyone,
verifies transactions to make sure they are valid,
stores a full copy of the network's history, known as the blockchain.
No individual or company can change the rules or the data. Any change to the network must be collectively approved by the majority of participants.
No company, no foundation
Unlike many other cryptocurrencies, Bitcoin has no active founder, no company behind it, and no foundation running it. This is precisely what makes it resilient: it does not rely on any organization to keep running. No one can shut it down. It can survive even if an entire country tries to ban it.
Who updates or improves Bitcoin?
Bitcoin's code is open source: anyone can read it, propose improvements, or flag issues. A global community of volunteer developers works together to fix bugs, improve security, and suggest new features.
Nothing changes automatically, however. For any change to take effect, it must be accepted and adopted by the majority of the network's nodes.
Bitcoin operates without a leader, a company, or any central authority. When its rules evolve, it is only because the global community decided so together.
