Hedera (HBAR) vs Stellar (XLM)

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.

Stellar is a layer 1 blockchain platform designed to support fast, secure, and low-cost value transfers between different currencies. Launched in 2014 by one of the co-founders of Ripple, another cryptocurrency project aimed at facilitating cross-border payments for businesses and institutions, Stellar focuses more on modest daily exchanges. The Stellar network uses a unique consensus protocol, the Stellar Consensus Protocol (SCP), which allows for rapid transaction confirmation without relying on Proof of Work (PoW) or Proof of Stake (PoS).
