This document summarizes 0chain, which provides blockchain-powered enterprise data storage. It enables high data security, better auditability, and lower costs through immutable recording of data writes and reads on the blockchain. The 0chain platform offers SaaS, IaaS, and on-premises/hybrid data storage and security options to protect enterprise applications like CRM, HCM, ERP and IoT from internal and external attacks through decentralized consensus of encrypted and fragmented data records.

5. Client generates markers
• Values signed by client
Blobbers later redeem markers
Markers prove blobber is storing the
correct data
Reading & Writing

6. Read Marker:
[READ,owner_id,data_id,blobber_id,
file_path,block_num,read_ctr]client
Write Marker:
[WRITE,trans_id,blobber_id,
file_size,merkle_rt(file_data),
write_ctr]client
trans_id = client_id,data_id,T
Markers

7. Blobber transaction completes exchange
• Closes connection
• Client's reads / writes consumed
• Blobber paid 0chain tokens
Redeeming Markers

8. File level storage
Approach patterned after Git
• File names based on hash of file contents
• Quasi Merkle tree-like structure
For each file, the most recent write_marker is stored
File Organization

9. Mining network challenges blobber to
provide a block of data
• Verifies that blobber has file
• Pays blobber
Challenge Requests
