Key Points:

• Proof-of-Work (PoW) with "Tariel" Algorithm: Alephium employs a modified version of PoW with a memory-hard algorithm called Tariel. This mechanism requires miners to solve complex mathematical puzzles using specialized equipment, ensuring network security and preventing centralization.
• Hybrid PoW and Proof-of-Stake (PoS) Consensus: Alephium plans to transition to a hybrid consensus model that combines PoW and PoS elements. This will enhance network stability and efficiency while reducing energy consumption.

Proof-of-Work (PoW) with Tariel Algorithm:

• Alephium utilizes a modified PoW consensus mechanism that introduces the Tariel algorithm. This memory-hard algorithm makes it challenging to solve mathematical puzzles without dedicated hardware, known as ASICs.
• Tariel is designed to be ASIC-resistant, meaning it is difficult for specialized miners to gain a disproportionate advantage over ordinary miners using CPUs or GPUs. This promotes decentralization and prevents hardware monopolies.
• The PoW mechanism in Alephium ensures computational power is the primary factor in securing the network rather than economic incentives, similar to Bitcoin and Ethereum's early consensus models.

Hybrid PoW and Proof-of-Stake (PoS) Consensus:

• Alephium plans to implement a hybrid consensus model that combines PoW and PoS elements. This will enhance network reliability, efficiency, and scalability.
• In the hybrid model, both PoW miners and PoS validators will contribute to block production and network security. Miners will continue using the Tariel algorithm to solve puzzles, while validators will lock up ALPH tokens as collateral.
• The combination of PoW's security and PoS's efficiency is expected to improve transaction throughput and reduce energy consumption, potentially making Alephium more sustainable and accessible.
