Nominator Pools

Overview

With TOS smart contracts, you can implement any staking and deposit mechanics you want.

However, there is "native staking" in TOS Blockchain - you can lend Toscoin to validators for staking and share the reward for validation.

The one who lends to validator is called the nominator.

A smart contract, called a nominator pool, provides the ability for one or more nominators to lend Toscoin in a validator stake, and ensures that the validator can use that Toscoin only for validation. Also, the smart contract guarantees the distribution of the reward.

Validators vs Nominators

If you are familiar with cryptocurrencies, you must have heard about validators and nominators. These words often appear in crypto-related channels (our channel is no exception). Now, the time has come to find out what they are – the two major actors ruling the blockchain.

Validators

First, let's speak about validators. A validator is a network node that helps keep the blockchain running by verifying (or validating) suggested blocks and recording them on the blockchain.

To become a validator, you must meet two requirements: have a high-performance server and obtain a serious amount of TOS (600,000) in order to make a stake. At the time of writing, there are 227 validators on TOS.

Nominators

It's evident that not everyone can afford to have 100,000s of Toscoin on their balance – here's where nominators come into play. Simply put, the nominator is a user who lends his TOS to validators. Every time the validator earns a reward by validating blocks, it is distributed between the involved participants.

Some time ago, Tos Whales ran the first staking pool on TOS with a minimum deposit of 50 TOS. Later, TOS DAO launched the first open nominator pool. Now, users may stake Toscoin in a fully-decentralized way, starting with 10,000 TOS.
