POSers are 5000 fancy dudes living on the blockchain. They're cool, they're diverse, they're pixelated, they're ON-CHAIN! Who are you - Human, Ape, Vampire, or Alien?
POSers are the first on-chain PFP collection launched since the Ethereum Network transitioned from Proof of Work to Proof of Stake.
Onchain means that everything in the collection is generated by a smart contract and permanently stored in a blockchain: code, images, and metadata! The collection is completely independent of server crashes and will not disappear over time.
POSers use the ERC-721A contract - as optimized as possible and requiring minimal gas to mint. With the transition of Ethereum to PoS, the gas fee for any action on the blockchain will also decrease significantly, and the speed of transaction processing will increase.
