## Accounts

A PROSOFT account is a pair of keys used to uniquely identify a user (or entity) and allow them to authenticate and verify transactions on the ProSoft Chain.

Accounts on ProSoft chain

There are two keys: A Public Key and a Private Key.&#x20;

The Public Key is used to generate an Address (or multiple addresses).

## An Account object is an implementation of an account keypair. It stores the following:

&#x20;

Public Key (PubKey)

Address derived from the Public Key

Account number (AccountNumber)

Sequence

Example Account object

type BaseAccount struct {

Address string \`protobuf:"bytes,1,opt,name=address,proto3" json:"address,omitempty"\`

PubKey \*types.Any \`protobuf:"bytes,2,opt,name=pub\_key,json=pubKey,proto3" json:"public\_key,omitempty"\`

AccountNumber uint64     \`protobuf:"varint,3,opt,name=account\_number,json=accountNumber,proto3" json:"account\_number,omitempty"\`

Sequence      uint64     \`protobuf:"varint,4,opt,name=sequence,proto3" json:"sequence,omitempty"\`}
