FAQ

Q: Can blockchain be hacked?
A: While theoretically vulnerable to 51% attacks, major networks like Bitcoin remain extremely secure due to the high cost of such attacks.

Q: Who maintains blockchain networks?
A: Maintenance varies between public chains (community-governed) and private chains (centrally managed), each with distinct advantages.

Q: Are smart contracts legally binding?
A: Current smart contracts lack the nuance of traditional legal systems, though the technology continues evolving toward greater sophistication.

Q: How does blockchain impact data privacy?
A: Blockchain creates permanent records, presenting challenges for regulations like GDPR that mandate rights to erasure.

Q: Is blockchain environmentally sustainable?
A: Newer consensus mechanisms dramatically reduce energy consumption compared to early Proof-of-Work systems.

Blockchain's business applications continue expanding across sectors, offering transformative potential despite current technical and regulatory challenges. As adoption grows, solutions to these limitations will likely emerge, further unlocking the technology's value.
