I have found interesting topic about innovations powering the Aptos network and made a little squeeze.
- The Move Language for Better Building
Move on Aptos creates a better developer experience for scalable, future-proof applications. Move, along with the Aptos framework, improves builder efficiency by intentionally removing unnecessary complexity that often limits developer accessibility.
Move is an expressive and accessible programming language emphasizing security and designed for safe asset management. Move brings to Web3 what Rust brought to infrastructure development – a safe, fast, and expressive method for mapping interactions.
The Aptos blockchain natively integrates the Move language. Aptos and Move share many of the same core design principles to make Aptos the home for efficient, enjoyable Move development. Move was initially designed for the predecessor of the Aptos blockchain. This relationship ensures existing Move developers can seamlessly build on Aptos and new Move developers benefit from the documentation, guides, and examples that predate Aptos.
- On-chain Governance and Decentralization
To support a truly decentralized and permissionless Layer 1, Aptos has built-in on-chain governance that enables seamless network and VM configuration changes. Aptos Incentivized Testnet 3 and Mainnet demonstrate this.
On Mainnet, this improved the network’s reliability by lowering the "voting power increase limit.” Set to a more aggressive threshold allowed a fast bootstrap of the network. Over 52% of token owners voted on this proposal to help secure our network.
Since genesis, the Aptos community has been able to create and vote on proposals that impact the behavior of the Aptos blockchain. Governance proposals can make changes spanning the epoch duration, or the minimum required and maximum allowed validator stake; modifying flags that result in taking advantage of software upgrades for core blockchain code; as well as upgrades to the Aptos framework modules, a set of core libraries for Move developers, for fixing bugs or enhancing the Aptos blockchain functionality.
- Proposal-Based Reward System
In the Aptos Incentivized Testnet 3, we leveraged voting-based rewards systems for node operators. In this model, once two-thirds of the votes reach the proposer node, consensus under BFT is achieved. This means that one-third of the later votes are not included, and their associated validators are not rewarded.
This can lead to latency competition, and validators closer to the main node cluster tend to be rewarded more. In these circumstances, node operators will move their nodes closer to the main cluster to improve latency and thus increase their staking rewards. This hurts decentralization and geographical distribution as it incentivizes co-location.
We’ve now implemented rewards based on proposal performance as our staking rewards system to promote greater decentralization.
Proposal-based systems have a higher timeout than voting and are arguably less sensitive to cross-region latency. This improves the reward rate of nodes in more remote regions and dampens the effect of geo-distribution, e.g., validators receive less reward if they’re not physically located in the biggest node cluster. Our reward model continues to account for voting behavior, as good voting performance influences proposer election probability.
