Overview

Package account implements Account used in Klaytn.

Inside the package, types, structures, functions, and interfaces associated with the Account are defined.

Type of Account

There are three types of Accounts used in Klaytn.

  • LegacyAccountType
  • ExternallyOwnedAccountType
  • SmartContractAccountType

AccountCommon implements the structure and functions common to Klaytn Account, which also implements the Account interface.

EOA (ExternallyOwnedAccount) and SCA (SmartContractAccount) are implemented in a structure that includes AccountCommon.

LegacyAccount is implemented separately according to the account interface.

Source Files

Account related functions and variables are defined in the files listed below.

  • account.go : Defines types, interfaces and functions associated with the Account.
  • account_common.go : Data structures and functions that are common to EOA (ExternallyOwnedAccount) and SCA (SmartContractAccount) are defined as AccountCommon.
  • account_serializer.go : AccountSerializer is defined for serializing Account.
  • externally_owned_account.go : ExternallyOwnedAccount containing an AccountCommon is defined.
  • legacy_account.go : LegacyAccount that implements the Account interface is defined.
  • smart_contract_account.go : SmartContractAccount containing an AccountCommon is defined.

Types

type Account 

type Account interface {
	Type() AccountType

	GetNonce() uint64
	GetBalance() *big.Int
	GetHumanReadable() bool

	SetNonce(n uint64)
	SetBalance(b *big.Int)
	SetHumanReadable(b bool)

	// UpdateKey updates the account's key with the given key.
	UpdateKey(newKey accountkey.AccountKey, currentBlockNumber uint64) error

	// Empty returns whether the account is considered empty.
	// The "empty" account may be defined differently depending on the actual account type.
	// An example of an empty account could be described as the one that satisfies the following conditions:
	// - nonce is zero
	// - balance is zero
	// - codeHash is the same as emptyCodeHash
	Empty() bool

	// Equal returns true if all the attributes are exactly same. Otherwise, returns false.
	Equal(Account) bool

	// DeepCopy copies all the attributes.
	DeepCopy() Account

	// String returns all attributes of this object as a string.
	String() string
}

Account is the Klaytn consensus representation of accounts. These objects are stored in the main account trie.
