Terms and Definitions¶
- WebAssembly
- The WebAssembly (abbreviated Wasm) is a software technology that allows you to use code written in C++ in the JavaScript environment.
- Wallet
- A wallet is software that stores a set of key pairs of asymmetric cryptography and allows you to perform transaction signing operations using them.
- HD Group
- An Hierarchical Deterministic wallet is a wallet that allows deriving hierarchical chains of key pairs from the initial master seed in a deterministic way.
- HD Wallet
- The wallet that consists of several HD Groups.
- HD Account
- An HD Account is a very specific intermediate node in the hierarchy of an HD Group (defined by the Semux specification), from which all other key pairs are derived.
- Address
- The term Address here means an object of the
Addr()class, which is essentially a key pair. - HD Address
- An HD Address is one of the Addresses in the HD Group hierarchy.
- non-HD Address
It is single Address not associated with the HD Group. It can be obtained by importing a private key or random generation.
Note
This library can simultaneously work with several non-HD addresses, and also with several HD Groups.
- Mnemonic phrase
Mnemonic phrase (or mnemonic sentence) - is a group of easy to remember words (space separated) for the determinate generation of the master seed (and, accordingly, HD Account) for certain HD Group in HD Wallet.
A mnemonic code or sentence is superior for human interaction compared to the handling of raw binary or hexadecimal representations of a wallet master seed. The sentence could be written on paper or spoken over the telephone.
- Semux-address
Aka “Hex address” or “Recipient address”. It’s a hexadecimal string that is the “official address” of some wallet to which you can, for example, transfer a certain amount of cryptocurrency.
In fact, a Semux-address is obtained by taking a double hash (Blake2B-SHA256) from the public part of the Address.
- Nonce
Nonce is a sequentially increasing and unique integer for the sender address. Max value is 9,223,372,036,854,775,807. Used to make transactions. If you do not know the next Nonce for a transaction, then you can get it by contacting the Semux node API.
In the parameters of the methods of this library, the Nonce is passed as a string decimal representation.
