Abstract:
Blockchain technology, distinguished by its decentralized and irreversible design, has
gained rapid adoption across sectors, offering heightened security and transparency.
Despite its promises, the rising usage of blockchain has given rise to new security issues.
This article undertakes an in-depth investigation of blockchain security, especially
addressing weaknesses in consensus mechanisms, smart contracts, privacy protection, and
network layers. Driven by the rising integration of blockchain across varied industries, the
study strives to decrease the distance between the prospective benefits of blockchain
technology and the security difficulties it faces. Research questions assist the examination
into significant vulnerabilities and the efficacy of current security solutions. The analysis
not only reveals complex weaknesses but also suggests robust security procedures,
anchored by a sustainability strategy. This concept envisions a future where blockchain
accords with ethical values and environmental issues. The findings obtained from this
research serve as a navigational tool for policymakers, system administrators, and
developers, encouraging an environment of trust, creativity, and sustainability in the world
of blockchain technology. The article finishes by identifying prospects, assuring continued
progress in the dynamic field of blockchain security. In summary, this research presents a
path to safe, morally based, and environmentally responsible blockchain technology
