After Cancun, are we welcoming blessings?
By Azuma, Odaily Star Daily
In recent days, there has been a lot of speculation surrounding the upcoming coin issuance and airdrop of zkSync.
The reason behind this speculation, apart from some team members continuously posting cryptic messages on social media, is the discovery of the phrase "zkPorter is available" within the Github code repository recently updated by Matter Labs.

Subsequently, Ethereum Daily, with over 80,000 followers on X, posted a tweet with the content "Are you ready to welcome ZK Endgame?" and included a "parachute" graphic hinting at the possibility of an airdrop, based on the basis of "zkPorter is available".

Perhaps due to the keywords zkPorter and Endgame, zkSync founder Alex Gluchowski later retweeted Ethereum Daily's tweet. This act was initially seen by the community as Alex acknowledging zkSync's upcoming airdrop. However, it may have been realized later that this behavior was highly suggestive, and Alex subsequently unretweeted the tweet.

Taking into account the above information, the main basis for the speculation about zkSync's airdrop focuses on zkPorter. So, what exactly is zkPorter? Why is the launch of zkPorter linked to zkSync's token?
The first appearance of zkPorter can be traced back to August 2020, when Matter Labs proposed this new scaling technology based on zkSNARK, aiming to achieve more significant scaling effects for Layer 2 through more flexible data availability (DA).
In an article in 2021 detailing zkPorter, Matter Labs mentioned that Rollup can only provide linear scaling effects because all data still needs to be broadcast to all full nodes. However, to accommodate the massive user growth, the industry needs to achieve exponential scaling effects.
To address this, Matter Labs designed a new scaling solution, zkPorter, which can achieve over 20,000 TPS while maintaining a security level between zkRollup and Optimistic Rollup.

Similar to zkSync Era, which uses the zkRollup solution, zkPorter also supports EVM, and their contracts and accounts can seamlessly interact.
The core difference between the two lies in zkPorter placing data availability off-chain (outside of Ethereum), thereby freeing the data from the restriction of being broadcast to full nodes and significantly reducing the gas cost required for transactions—thousands of transactions can be bundled into a single update released to the mainnet.

From the early definition of Layer 2, zkPorter's solution should be classified as Volition, more suitable for high-concurrency projects that are not suitable for the Ethereum mainnet or traditional Rollup in terms of economic effects.
A crucial design aspect is that to ensure the stability of zkPorter, the data availability of zkPorter needs to be guaranteed by zkSync token holders (referred to as guardians here). Guardians can use zkSync tokens to participate in PoS proof, track the state of zkPorter by signing blocks, and confirm the data availability of zkPorter accounts.
This is why the community associates the information "zkPorter is available" with "zkSync's upcoming coin issuance".
So, when will zkPorter go live? Alex himself mentioned in February this year in response to community questions that it would be after the execution of EIP-4844, as they need to observe the potential impact of this upgrade on transaction fee changes. Considering that EIP-4844 (Proto-danksharding) will be executed in the Dencun upgrade on March 13, it can be expected that zkPorter will not be too far away.

It is important to emphasize that, like the wider community, we also do not know the specific coin issuance and airdrop plans for zkSync. The above information about the launch time of zkPorter only provides a one-way range and cannot provide more precise speculation.
For security and stability considerations, Matter Labs will only proceed with relevant actions when everything is ready. Therefore, there may still be a period of observation and testing after EIP-4844.
The "blessings" will eventually come, so please be patient.
