ONCHAIN STORAGE (OCS)

/// @notice Function to add onchain data

One of the largest files ever stored on an EVM chain.

The OCS protocol developed alongside Transient Labs combines IPFS + onchain storage to create a hybrid & future-proof system. The NFT itself still uses IPFS to store the metadata. This ensures that web2 systems don’t break and that the NFT is as high of quality as possible.

In addition to the NFT, there are separate contracts that store the NFT onchain. The 100 megabyte video is broken up into 100kb chunks and uploaded one at a time. Each chunk is stored in the event log of a particular transaction, making it part of the blockchain history.

We can then recreate the NFT in its entirety by retrieving each chunk from the blockchain and smashing the chunks together offchain.
