Differences from geth

GoQuorum is a lightweight fork of geth to take advantage of the R&D within the Ethereum community. GoQuorum is updated as geth releases occur.

GoQuorum includes the following modifications to geth:

• Consensus is achieved with the Raft or Istanbul BFT consensus algorithms instead of Proof-of-Work.
• The P2P layer is modified to only allow connections between permissioned nodes.
• The block generation logic is modified to replace the global state root check with a global public state root check.
• The block validation logic is modified to replace the ‘global state root’ in the block header with the ‘global public state root’
• The State Patricia trie has been split into two: a public state trie and a private state trie.
• Block validation logic is modified to handle private transactions.
• Transaction creation is modified to allow for transaction data to be replaced by encrypted hashes to preserve private data where required.
• The pricing of gas is removed. Gas itself remains.
