Aptos is a Proof of Stake blockchain, meaning it uses a network of validators to securely process and verify transactions.
It uses Move, a smart contract programming language that focuses on safety and flexibility. This means that it is quite modular. With its ability to upgrade modules and its programmability, the Move language can facilitate upgrades that are quite seamless. Under its programmable framework, it also offers developers more control over data management and execution.
Aptos’s consensus mechanism, AptosBFT, is a byzantine fault tolerant consensus mechanism. What this basically means is that the system can function even with a certain amount of component failure and trustlessness. What is also very promising is that one of the network’s core design principles is its emphasis on scaling horizontally, utilizing sharded ledger states. This will alleviate network stress as it grows.
