 Hashgraph vs Blockchain

They solve the double spending problem. So you can have
  • Sigital currencies,
  • Smart contracts,
    • Dapps,
  • DAOs
  • Markets
Key Characteristics of Swirlds Hashgraph
  • Consensus Ordering and fairness of transactions are the centerpiece of Swirlds.
Simply put, Swirlds seeks to fix the ordering problem found in the blockchain world today (due to different consensus methodologies that have trouble addressing this problem) by using Hashgraph Consensus and "gossip about gossip".
  • Hashgraph can achieve consensus with no Proof of Work.
    So it can be used as an open system (non-permissioned) using Proof of Stake, or it can be used as a permissioned system without POW or POS.  There's no mining. Any member can create a block (called an "event") at any time.It supports smart contract creation.Blocksize can be whatever size you want. When you create a block ("event"), you put in it any new transactions you want to create at that time, plus a few bytes of overhead. So the block ranges from a few bytes (for no transactions), to as big as you want it (for many transactions).  But since you're creating many blocks per second, there's no reason to make any particular block terribly big.The core hashgraph system is for distributed consensus of a set of transactions. So all nodes receive all data.  One can build a sharded, hierarchical system on top of that. But the core system is a replicated state machine. Data is  stored on each machine. But for the core system, the data is replicated.
Personally, I think if the claims are true. This could the the end of the blockchains praradigm.
