STRATO 9.0.0 Release Notes

February 1, 2023

Features, Improvements, and Updates:

• External Key Vault for STRATO nodes - enables multiple STRATO nodes to connect to the same key management server
• By default, user IDs are used to link addresses in Shared Vault instead of email addresses
• Enabled Private Shards to read from multiple other shards (previously only one parent shard was allowed)
• STRATO Management Dashboard
  • Pagination is enabled in the "Chains" page
  • History toggle available in the "Create Chain" and "Create Contract" modals
  • Improved navigation experience to the "Contracts" page
  • Added link added to STRATO Developer Documentation
  • The "Create Contract" modal now has default values and autofills chain ID & label to the currently selected chainID
  • SMD references to "private chain" have been removed and changed to "private shard"
• Developers will now know when private shard creation fails due to a runtime error - the POST /chain API now properly gives error responses in these scenarios
• The chain ID of a contract is now accessible in its hex-string representation on the this built-in member
• POST /transaction endpoint responds with a more informative error message when a contract and/or chainID pair doesn't exist
• Private shard constructors no longer have empty block timestamps
• Cirrus history tables are always on for contracts
• Network validators moved from address based user identity to x509 certificate based identity opening up the scope for verified identities, KTC, KYB, AML
• Shard IDs and private transaction hashes can no longer be accidentally reused
• New metatadata endpoint for easier attainability of: node's pubkey, list of validators, node sync status and other administrative checks
• Genesis block updates to be configurable, specify network validators, admins, and pre-load X.509 certificates

Bug Fixes

• Default Governance Contracts for private shards in SMD no longer have syntax error
• SMD ‘Create Chain’ modal now has a contract selection option
• SolidVM now stores the correct organization of the creator of a Private Shard when using Code Pointers
• Governance contracts without explicit constructors now cause chain creation to fail
• Create Chain endpoint now returns an error when the governance contract throws a type or runtime error
• P2P communication limited based on networkID (Nodes with different networkIDs are put on a blocklist)
• Adding private chain members makes peers connect directly to each other
• Network validator voting moved to smart-contract based governance in the Genesis Block at the static address of 0x100
• Identity Management Dapp (CertificateRegistry) moved to the Genesis Block at the static address of 0x509
