Play-to-earn games

Axie Infinity is a Pokmon Go-like game, where players raise, breed and battle their digital pets called Axies. However, unlike in traditional games where characters are valuable primarily within the game, every Axie is a nonfungible token, or NFT, which refers to noninterchangeable digital assets stored on blockchains.

Axies, which can be bought and sold at the platforms marketplace and other secondary markets such as OpenSea, worth at least $150 each.

Players may also earn AXS and another token Small Love Potion (SLP) in the game, while both tokens can be traded at some crypto exchanges such as Uniswap. SLP is recently trading at $0.096, up 32% during the past 24 hours, according to CoinGecko.

There is an entry barrier, though youll need to acquire at least 3 Axies to start playing the game.

Developed by Vietnamese studio Sky Mavis and released in 2018, Axie Infinity is especially popular in places such as the Philippines, where some people play the game to earn a living.

Why does staking matter?

In a proof-of-stake (POS) blockchain, holders of the cryptocurrency could help validate transactions and thus earn a reward.

Staking on Axie Infinity currently has an APR of 187%, according to a page on Axie Infinity.

Different from bitcoins proof-of-work system, which requires computational power to verify transactions, the POS system claims to be more environment-friendly.

Ethereum is in the process of transitioning from proof-of-work to proof-of-stake.
