would be good idea to abstract, basically as account for specific blockchain, then have only one way how to list assets, send money, do multisig, ... and depending of the blockchain have different implementation

IMPORTANT

• there is duplication now, asset & model

fn db_get(path0 string) !MoneyDB

fn deserialize(data []u8) !Position

fn keysafe_get(path0 string, secret string) !PrivKeysSafe

struct Account {
pub mut:
	uid       u32
	pubkey    ed25519.PublicKey
	positions []Position
}

struct Asset {
pub mut:
	uid          u16
	name         string
	maxinstances u32
	maxparts     u16 // how many max parts per instance e.g. an art piece can be owned 1/8, so 8 parts. 	
}

struct Position {
pub mut:
	asset    u16
	instance u32
	part     u16
}

fn (p Position) serialize() []u8

struct PrivKey {
pub:
	id      u16
	name    string
	privkey libsodium.PrivateKey
	signkey ed25519.PrivateKey
}

fn (pk PrivKey) serialize() []u8

struct PrivKeysSafe {
pub mut:
	path        pathlib.Path
	secret      string
	privatekeys map[int]PrivKey
}

fn (mut ks PrivKeysSafe) generate(count int)

fn (mut ks PrivKeysSafe) serialize() []u8
