      Radix DLT with their Cerberus consensus algorithm is the only legitimate scaling solution for DeFi that I've seen. I think it will become clear by the end of this year that Ethereum, Solidity, Layer 2 solutions, just aren't capable enough.

    Based Rollups are indeed a game-changer, offering a seamless way to leverage Ethereum's robust sequencer for transaction ordering.
    It's interesting to compare this with "Taiko's" work on BBR and BCR, which also aim to enhance Ethereum's scalability and efficiency.
    The collaboration between these technologies could significantly strengthen the Ethereum network, making it more cohesive and powerful.

    • @danielbenson2653
      @danielbenson2653 2 ปีที่แล้ว +1

      true, but it literally only takes 1 actor to check. So, theoretically institutions or individuals making significant transactions on on the network will have the incentive to check the rollup that there transaction is in for the security of their funds but at the same time verifying all the other transactions in that roll up as well. I mean imagine you converted ETH to 1,000,000 USDC. Wouldn't you at least run a verification of the block that transaction was in to make sure you weren't scammed?

    If there will actually be only 1 txn being made on the ETH chain for that 1000 txns made on the rollup chain, how does security exactly work for each transaction on the ETH chain? How are the 1000 txns exactly confirmed and secured at the transaction level per ETH addresses? Are there 1000 ETH addresses involved?..

    The liquidity issue will probably not be a big deal with arbitrageurs correcting inefficient prices. Only if somebody wants to do a large transaction all at once, rather than in small chunks over time. But small chunks would be much more feasible with the lower gas fees in rollups etc.
