V God: After sharding and Rollups solve congestion, The Graph may be one of the feasible data storage solutions

Ethereum founder Vitalik Buterin called The Graph a possible data storage solution, planning to use highly scalable ZK-Rollup to revolutionize the throughput of the Ethereum 2.0 network.

After a large number of users complained about the extremely high gas fees on the network, Vitalik Buterin published an article entitled "A Step-by-Step Roadmap to Scaling Rollups". In the article, Buterin believes that this phenomenon can only be solved through the large-scale adoption of ZK-Rollup.

“Rollups are the only trustless scalability solution for Ethereum in the short to medium term, and possibly long term,” he wrote.

“Transaction fees on Ethereum L1 have been high for several months now and it is even more urgent now to take whatever action is necessary to help move the entire ecosystem forward Transfer to Rollups."

"Rollups have already significantly reduced fees for many Ethereum users: l2fees.info often shows that the Optimism and Arbitrum networks have lower fees than the Ethereum base layer itself zk-Rollups have better data compression and can avoid including signatures, so their fees are about 40-100 times lower than the Ethereum base layer.”

Zero-knowledge is a simple and highly secure encryption technique. It enables one party to verify that another party's blocks are true without providing proof of blockchain data.

This essentially creates a protocol where digital transactions can take place without anyone seeing anyone else's sensitive data and is compressed, which reduces the amount of blockchain data that must pass through the network, thus providing scalability.

ZK-Rollups go one step further - bundling hundreds of transfers into a single smart contract transaction. The smart contract can automatically unpack transactions and verify any of them.

Sharding + Rollups = Super High Scalability

Buterin believes that in the long run, Rollups will eventually have an upper limit, and some users will not even be able to pay the reduced gas fee.

“However, for many users, even these (in Rollups) fees are prohibitively expensive.”

"For a long time, data sharding (data sharding) has been considered as a solution to the long-term deficiencies of Rollups in its current form. Adds about 1-2MB/s dedicated data space for Rollups on the Ethereum chain.”

Sharding attempts to subdivide the load of data that needs to be processed for something to happen.

By sharding transaction information among many nodes that are only responsible for processing and storing a single piece of information - this reduces the workload required for nodes to verify transactions.

This will happen after the Ethereum 2.0 Proof of Stake (PoS) mainnet goes live.

Vitalik Buterin's idea is actually "Rollups on top of the shards", but that creates its own problems - from all these shards Where will historical data be stored?

Enter The Graph

At the end of Vitalik Buterin's release of the roadmap, he has addressed the question of where exactly all this data can go - he suggests institutional volunteers, DAOs, district Block explorers and torrents are mentioned in The Graph at the end as theoretical solutions.

"Protocols like The Graph can create incentivized markets where clients pay servers for historical data and merks proving its correctness I'll prove it."

This incentivizes people and institutions to run servers that store historical data and make that data available on demand. "

Even though the ongoing GRT Token issuance program dampened the excitement, the market briefly reflected optimism.
