What’s new? After the Dencun hard fork in the Ethereum main blockchain, with which the EIP-4844 enhancement was introduced, transaction fees dropped significantly in Layer 2 (L2) networks based on it. For example, the average fee on the Optimism network dropped by 99% to less than $0,001, which was the best result among Ethereum-based L2 networks, according to the L2 Fees portal.
What else is known? According to data from analytics platform Dune, between 00:00 and 01:00 UTC, Optimism had an average transaction fee of $0,05 and a median of $0,0038; Base had an average of $0,064 and a median of $0,0008; Arbitrum had $0,5 and $0,3553; and zkSync Era had $0,161 and $0,0936, respectively.
According to Base developer Jesse Pollak, fees on the network dropped from $0,31 to $0,0005 thanks to the upgrade.
The Dencun upgrade enabled the introduction of proto-danksharding into the mainnet, which scales the blockchain and reduces the cost of gas by introducing a new mechanism for storing compressed large arrays of binary data (blobs).
Ethereum co-founder Vitalik Buterin explained that blobspace transactions are similar to regular transactions, except that they carry an additional piece of data called a blob object. “Blobs are extremely large (~125 kB), and can be much cheaper than similar amounts of calldata,” he added.
By the time of writing, 3788 blobs have been used. It is expected that L2 networks using them will face increasing fees in the future. As more Ethereum scaling solutions adopt blobs, competition for storage space increases, which may lead to a slight increase in transaction costs.
