"The core of #IOTA lies in the Tangle, a structure where new transactions validate previous ones, in contrast to the typical blockchain used by most DLTs. In blockchain-based systems, transactions are grouped into blocks and linked together, creating a natural bottleneck. However, IOTA bypasses this limitation [with] the Tangle, which... eliminates the need for centralized validation and offers a decentralized and secure environment for transactions and data exchange."
