Hedera (HBAR) vs Mantle (MNT)

Hedera Hashgraph is a layer 1 blockchain platform that aims to be a more efficient, secure, and reliable distributed ledger than Bitcoin. The protocol is based on Proof of Stake (PoS) and is powered by a unique technology called Hashgraph, which incorporates concepts from directed acyclic graph theory for node management and a mechanism called "gossip protocol" for transaction validation.

Mantle is a layer 2 scalability solution for Ethereum, whose technological infrastructure ensures full compatibility with the Ethereum Virtual Machine (EVM), facilitating the creation of smart contracts and decentralized applications (dApps). Mantle is an atypical Optimistic Rollup as it has a modular architecture: the network only handles transaction execution, while consensus is managed by Ethereum and data is decentralized with EigenDA. It is worth noting that Mantle is the result of an evolution of ByBit's BitDAO ecosystem.
