I agree about the garbage, Obyte DAG doesn't need it and garbage shouldn't need to be decentralized and timestamped either.

It's a community project and community funded (not a project by Obyte Foundation), but Obyte Foundation and rest of the community already do DeFi:

Obyte doesn't have to do the same thing with ethereum, although ethereum is getting credit with the DeFi project but unfortunately that's on the investor side but not the community currently complaining about the high transaction fees of the ETH network and whereas ETH is not ready to launch ETH 2.0 yet, that's true broken right

It's not a graph of nodes communication, but graph of transactions. The transactions are not put into blocks, transactions have DAG structure. Obyte doesn't use blockchain.

There is no block producers (miners), everyone with a full node can add a transaction directly to DAG and you don't have to bribe miners to include your transaction to block. Transactions are linked to each other, no linked blocks and no reorgs of already confirmed transactions.
