on GitHub

What's new since 3.0

🚨 Breaking Changes

• New MRENCLAVE values for all enclaves (see Enclave Measurements section below).
• Block Version 3 (which will be enabled after deployment) requires a transaction to sign the TxSummary instead of TxPrefix.
• Block Version 3 requires transactions to sort TxOs.

✨ Features

• Signed Contingent Inputs allow for a single TX containing multiple token types, enabling atomic swaps and partial transactions.
• MintTx can now be used to mint directly to a fog-enabled address.
• Minting transactions can optionally use nested multi-signatures.
• Consensus nodes now publish block metadata signed by their SCP message key
• All services can optionally output log messages in json format

🔒 Security

• Consensus enclaves now enforce unique nonces on a per-token basis
• Consensus enclaves now reject transaction proposals when the client's fee map differs from the configured fees in the enclave
• SGX SDK upgraded to 2.18
