Layer 2 Blocks
The Question :
How many layer2 StarkNet blocks have been accepted on Ethereum (L1) chain so far? How much fees have been paid(generated) to Ethereum network? Has StarkNet contributed to saving in transaction fees for its users?
Methodology :
Each StarkNet block is registered on ethereum blockchain by means of a transaction emanating from the StarkNet operator: 0x2C169DFe5fBbA12957Bdd0Ba47d9CEDbFE260CA7 to StarkNet core contract: 0xc662c410C0ECf747543f5bA90660f6ABeBD9C8c4
so, I have counted the tx_hash related to each block generation
Findings :
-
Each StarkNet block is registered on ethereum blockchain by means of a transaction emanating from the StarkNet operator to StarkNet core contract.
-
total number of registered blocks is 2054, which generated a fee of 32.28 ETH
-
avg fee per tx in starwake deposit and withdraws is 0.0.004 which is almost 8 times lower compared to average sushiswap fees on January 2022 which was 0.03
