@stompix is of course correct that Doge from time to time has a much higher transaction count and also "data throughput" than Bitcoin. However, there are two things making me believe that the Doge chain is much "lighter" than a 10MB Bitcoin chain would be.

First, let's see longer terms:


We see that until 2023 the Doge transaction count was much, much lower than Bitcoin's, even if the capacity in theory was higher. This should have resulted also in a smaller UTXO set, and UTXOs are one of the "bottlenecks" for full nodes. The average should be quite close for the recent 2 years.

In addition Doge's "usage boost" in 2023 is a phenomenon very closely related to the Doginals (Ordinals pseudo-clone) boom. This means there were some huge transaction "waves" with "NFTs" created on the Doge chain, even more than what occurred on Bitcoin. While they have more impact on the UTXO set than Runes or the original Ordinals because they don't inscribe in a witness but in an output as far as I'm aware of, per transaction it should be lower than a "payment" transaction because a lot of the data can be ignored by validators.

In general I think a 10MB Bitcoin chain should still be ok. But it would harm the fee market (transaction fees would probably go back close to 1 sat/vByte) and thus miner income. And in addition it probably needs a hard fork, and as I wrote in the discussion with MeGold666 I think the hassle isn't worth it and L2s are a better option.
