What is this?
Canopy is the official Go implementation of the Canopy Network Protocol, a recursive blockchain framework where new chains bootstrap off a 'seed chain' to launch with built-in security and consensus instead of starting from scratch.

No — the recursive model lets new chains bootstrap off existing ones but eventually become independent, together forming what the README calls 'an unstoppable web of utility and security.'What keeps the network safe if some nodes misbehave?Canopy uses Byzantine Fault Tolerant (BFT) consensus, which lets the network agree on new blocks even when some nodes are unreliable or malicious.
