To sustain elevated performance amid rising demand, systems must boost their capacity to process transactions per second (TPS) without latency spikes. Current public ledgers often struggle beyond a few hundred TPS, triggering bottlenecks that degrade user experience and inflate operational costs. Implementing layer-2 solutions or sharding techniques can multiply effective throughput by distributing workload while … Read more

The price paid for executing operations on the Ethereum network directly correlates with the amount of computational effort required. Each transaction consumes a quantifiable unit–gas–that reflects resource utilization, including CPU cycles, memory access, and storage writes. Understanding this metric is critical for predicting expenses and optimizing smart contract design to minimize expenditure while maintaining functionality. … Read more

Eclipse attacks – network isolation vulnerabilities

Mitigating risks associated with manipulating a node’s peer connections requires stringent control over inbound and outbound links. Attackers exploit the ability to monopolize all communication channels of a target node, effectively severing its access to legitimate participants. This form of containment disrupts consensus protocols and can lead to misinformation propagation or transaction censorship. Nodes relying … Read more

Distributed ledger technology – decentralized data storage
