Layer Two Security Risks

Architecture

Layer two security risks fundamentally stem from the architectural complexities introduced by scaling solutions designed to alleviate congestion on primary blockchains. These solutions, while enhancing transaction throughput, often necessitate trade-offs in decentralization or introduce novel attack vectors not present in the base layer. Specifically, vulnerabilities can arise from the trust assumptions placed on operators managing state channels, sidechains, or rollups, creating potential points of failure or manipulation. The design of consensus mechanisms within these layers, differing from the base layer’s proof-of-work or proof-of-stake, also presents unique security considerations regarding data availability and validity.
