Nano XNO: Token Swap

What are Epoch blocks?

Epoch blocks are the final stage of the Universal Block network upgrade and designate the end of the Legacy block (send/receive/change/open) era. Upon the addition of an Epoch Block to an account-chain, old-style blocks added to the account-chain will no longer be validated by the node software.

Following Epoch Blocks:

- An account-chain can no longer generate legacy blocks.
- Any transaction following the epoch block on the account-chain must be received by a state block.
