Sequential Bottleneck

Definition ∞ A sequential bottleneck is a point in a process where tasks must be executed one after another, thereby limiting the overall speed and efficiency of the system. In blockchain technology, this often refers to the inherent limitation of many networks where transactions are processed strictly in order, even if they are logically independent. This constraint prevents parallel processing, leading to reduced transaction throughput and increased latency during periods of high network demand. Overcoming these bottlenecks is crucial for achieving greater scalability and responsiveness in decentralized systems.
Context ∞ Sequential bottlenecks are a fundamental challenge in blockchain design, frequently discussed in the context of network congestion and high transaction fees for platforms like Ethereum. Researchers and developers are actively exploring various solutions, including parallel execution environments and sharding architectures, to alleviate these limitations. Progress in addressing sequential bottlenecks is vital for the widespread adoption of decentralized applications and digital assets.
