Aptos vs Sui

- Revive Diem’s technology by utilizing its programming language, Move, to create a scalable, secure, and flexible infrastructure that could compete with existing blockchains like Bitcoin and Ethereum.
- Ensure high throughput, low latency, and verifiable state synchronization in a decentralized network by leveraging Diem’s architecture along with a wide variety of novel techniques.
- The first milestone requires the separation of consensus from execution. By eliminating the co-dependencies that come with combining consensus and execution, higher throughput and latency are achieved.
- The second milestone is achieving optimized transaction execution times through the use of an in-memory smart contact parallel execution engine called Block-STM. STM stands for Software Transactional Memory, a new approach to engineering that supports flexible transactional programming of synchronization procedures. However, when applied generally, STM models suffer from performance limitations due to a conflict between bookkeeping and aborts. With that said, upon evaluation Aptos Labs has concluded that when applied to specific use cases such as DLT along with a combination of innovative techniques, they were able to achieve 100k+ TPS with 32 cores within their execution-only benchmark. Furthermore, their experimental evaluation has also shown that Block-STM outperforms sequential execution by up to 20x on low-contention workloads, and up to 9x on high-contention ones.
- The third milestone is achieving an optimized authenticating data structure. To combat the scalability issues that come with writing Merkle-trees to persistent storage, Aptos is developing authenticated data structures with the aim of being a scalable, database-friendly solution. This will be achieved through the evaluation of higher branching factors, access pattern optimized caching, and careful versioning,
- APT will have an initial supply of 1 billion tokens
- 51.02% will be distributed to the community with an anticipated distribution schedule of a 10-year vesting period, with 125M unlocked at genesis.
- 19.00% will be distributed to core contributors (Aptos Labs and advisors) with an anticipated distribution schedule of a 4-year vesting period, with a 13-month cliff and monthly unlocks thereafter.
- 16.50% will be distributed to the Aptos Foundation, with an anticipated distribution schedule of a 10-year vesting period, with 5M tokens unlocked at genesis.
- 13.48% will be distributed to the project's investors with an anticipated distribution schedule of a 4-year vesting period, with a 13-month cliff and monthly unlocks thereafter.
- The total supply of SUI is capped at 10,000,000,000 (i.e., ten billion tokens). A share of SUI’s total supply will be liquid at mainnet launch.
- The remaining tokens vesting over the coming years will be distributed as future stake reward subsidies. The exact allocation percentages for the distribution have yet to be released.
