Daggers are mined in every main block. For first 4 years 1024 XDAG are mined in each main block. For second 4 years - 512 XDAG, and so on. So, maximum XDAG supply is approximately power(2,32). Each dagger is equal to power(2,32) cheatoshino. Transaction is valid if it is referenced by a main block. Valid transactions are strictly ordered depending on main chain and links order. Double spending is prohibited because only first concurrent transaction (by this order) is applied.

## Security
The ECDSA algorithm with a 256-bit private key is used for a signature that confirms the rights of the wallet owner for money in the given address. All messages are transmitted between hosts in an encrypted form using the author's semi-symmetric encryption algorithm. The session key to it is transmitted using the 8192-bit key RSA algorithm.
