Ethereum L2 has a somewhat counterintuitive issue:
More scaling space does not mean every bit of space is fully utilized.
After EIP-4844 introduced Blobs, Rollups can publish data to Ethereum at a lower cost.
But for smaller-volume L2s, there is a choice:
Waiting to accumulate enough transactions before submitting can improve space utilization but may increase waiting time.
Submitting frequently offers a better user experience but may waste already paid-for data space.
So besides continuously increasing Blob capacity, another research direction is to enable multiple Rollups to share data space more efficiently.
In the future, measuring L2 efficiency might not only consider transaction fees but also data space utilization and transaction confirmation delay.
There was recent news about Solana that I think is more worth paying attention to than just announcing TPS.
On November 5th, Solana officially announced that eligible US Galaxy users can now directly buy, hold, send, and receive USDC through Samsung Wallet.
The interesting part is that ordinary users don’t necessarily need to download a dedicated Web3 wallet first to access on-chain stablecoins.
Blockchain is starting to enter the mobile wallets that people are already using.
Today's drop in the crypto market, I think the most noteworthy issue is not a single piece of negative news, but that both capital and leverage have encountered problems.
Last week, BTC and ETH spot ETFs continuously saw capital outflows, weakening the spot buying power.
Today, the total market liquidation scale reportedly reached about $1.11 billion, with ETH around $492 million, even higher than BTC's approximately $298 million.
Policy uncertainty after the midterm elections, macroeconomic expectations, and exchange security incidents are all affecting sentiment, but what truly amplified the decline was the concentrated forced liquidation of long positions.
What I want to see next is: after the leverage is cleared, will the spot buying return?
A digital bank in the UAE has integrated a US dollar stablecoin into its banking app today.
On November 9, Liv, a subsidiary of Emirates NBD, announced a partnership with Universal and Aquanow to integrate USDU into its existing banking services.
Interestingly, the bank itself does not issue the stablecoin.
Universal is responsible for issuance, Aquanow provides trading and liquidity infrastructure, and Liv handles the user interface.
USDU is registered under the relevant regulations of the UAE Central Bank, with the issuer claiming it is backed 1:1 by US dollar reserves and provides monthly reserve attestations.
However, a detail easily overlooked in the press release is that USDU is not a general payment tool within the UAE.
Therefore, the key point of this rollout is not that people can already use stablecoins to buy things in supermarkets, but that the bank is starting to embed regulated stablecoin trading services directly into everyday financial apps.
What will be worth watching in the future is whether users actually use it, whether it can be conveniently exchanged, and whether it will ultimately be used for payments or mainly remain in asset trading.

EIP-7702 now allows regular wallet addresses to delegate smart contract code to execute operations, enabling features like batch transactions and gas fee payments.
This convenience comes with a caution: when signing, you need to clearly understand whether you are confirming a transaction or granting new execution permissions to your account.
The official Ethereum security guide explicitly warns that mistakenly delegating to a malicious contract could lead to your account assets being controlled.
On November 6, Uniswap Labs proposed a fix for the fee release mechanism on X Layer.
Originally, the protocol fees on X Layer have been accumulating normally, but due to cross-chain bridge compatibility issues, these fees could not be released properly, and the corresponding UNI has not yet been burned.
This means that the protocol's generated revenue may not all enter the burn process in a timely manner.
Now the team proposes to fix this with AggLayerReleaser, expected to enter Snapshot on or after November 13.
UNI's X Layer fee mechanism encountered a bridging compatibility issue.
Governance messages can be transmitted via the OP Stack message bridge, but UNI token transfers need to go through Agglayer. The original releaser did not adapt to this path, causing fees to accumulate and preventing their designed release and destruction.
On November 6, Uniswap Labs proposed a new contract fix, expected to enter Snapshot on or after November 13.
What’s worth watching next is the actual execution of transactions, not just the voting results.
Uniswap v4's protocol fees no longer set a fixed rate for all pools.
It introduces V4FeePolicy and V4FeeAdapter, which can apply different fee rules based on pool type, hooks, and other conditions.
This means that in the future, even with the same trading volume, different pools may contribute different fees to the protocol.
What I'm more curious about is: which types of v4 pools ultimately contribute the most protocol revenue?
This might be more worthwhile to study than simply focusing on how much UNI is burned daily.
