Account Model

In order to join the NEAR ecosystem, users need to create an account. NEAR accounts are unique when compared to other blockchain ecosystems.

Human-Readable Accounts

NEAR leverages human-readable accounts to simplify remembering them. In this way, accounts have addresses such as alice.near instead of long strings of random characters.

Permissions Through Access Keys

NEAR accounts can have multiple keys, each with their own set of permissions. This allows to grant specific authorizations to third-parties, while keeping the option to revoke them at any time.

Simple to Develop Smart Contracts

NEAR accounts can optionally hold a simple program, known as a smart contract. In NEAR, developers can create smart contracts using languages such as Javascript or Rust.

Mutable State (Storage)

NEAR accounts have a state (storage) which can mutate when the user or the account's contract performs a transaction.

Comparison With Ethereum

Nếu bạn đã quen với develop trên Ethereum, bạn nên ghi chú nhanh về sự khác biệt của các account. The table below summarizes some key differences:

Secret KeyPrivate Key (0x456...)Multiple Keypairs with permissions:
- FullAccess key
- FunctionCall key
Characteristics- Private key gives full access
- Account doesn't have to be created via a transaction
- Permission-based keypair
- Account ID must be created via blockchain transaction
