	// Chain permissions.
	// These permissions grant the ability for accounts to perform certain transition within the execution package
	// Root is a reserved permission currently unused that may be used in the future to grant super-user privileges
	// for instance to a governance contract
	Root PermFlag = 1 << iota // 1
	// Send permits an account to issue a SendTx to transfer value from one account to another. Note that value can
	// still be transferred with a CallTx by specifying an Amount in the InputTx. Funding an account is the basic
	// prerequisite for an account to act in the system so is often used as a surrogate for 'account creation' when
	// sending to a unknown account - in order for this to be permitted the input account needs the CreateAccount
	// permission in addition.
	Send // 2
	// Call permits and account to issue a CallTx, which can be used to call (run) the code of an existing
	// account/contract (these are synonymous in Burrow/EVM). A CallTx can be used to create an account if it points to
	// a nil address - in order for an account to be permitted to do this the input (calling) account needs the
	// CreateContract permission in addition.
	Call // 4
	// CreateContract permits the input account of a CallTx to create a new contract/account when CallTx.Address is nil
	// and permits an executing contract in the EVM to create a new contract programmatically.
	CreateContract // 8
	// CreateAccount permits an input account of a SendTx to add value to non-existing (unfunded) accounts
	CreateAccount // 16
	// Bond is a reserved permission for making changes to the validator set - currently unused
	Bond // 32
	// Name permits manipulation of the name registry by allowing an account to issue a NameTx
	Name // 64

	// Moderator permissions.
	// These permissions concern the alteration of the chain permissions listed above. Each permission relates to a
	// particular canonical permission mutation or query function. When an account is granted a moderation permission
	// it is permitted to call that function. See snative.go for a marked-up description of what each function does.

	SetBase
	UnsetBase
	SetGlobal
	HasRole
	AddRole

	NumPermissions uint = 14 // NOTE Adjust this too. We can support upto 64

	TopPermFlag      PermFlag = 1 << (NumPermissions - 1)

	DefaultPermFlags PermFlag = Send | Call | CreateContract | CreateAccount | Bond | Name | HasBase | HasRole
