# Proof of Meta Consensus Mechanism
Although it seems that Ethereum's transition from PoW to PoS and the relatively new networks started directly as PoS have eliminated the need for miners, validators in PoS systems have undertaken the technical requirements such as providing and maintaining servers.
| Implementation | Proof of Meta (PoM) | Proof of Work (PoW) | Proof of Stake (PoS) | Delegated Proof of Stake (DPoS) | Proof of Authority (PoA) |
|---|
| Accessibility | High | High | High | Low | Low |
| Decentralization | High | Yes | Partially | Partially | Low |
| Scalability | High | Low | High | High | High |
| Low Latency | Yes | No | Yes | Yes | Yes |
| Transparency | High | High | High | Partially | Low |
| Smart Contract | Yes | Limited | Yes | Yes | Yes |
| Security | High | High | Partially | Partially | Partially |
| Network Intensive | Partially | Yes | Partially | Partially | No |
Metatime argues that mining needs to go beyond providing servers to users who are already on the blockchain network and are in focus. In addition, it has been determined that since mining requires such technical knowledge that only experts have, it cannot create sufficient resources to direct the future of blockchain technologies and meet the needs of the end user.
For this reason, **the hybrid mining system Proof of Meta (PoM)**, exclusive to MetaChain, allows people to directly contribute to the whole ecosystem and lead the ecosystem – as well as systems that work directly integrated with the network – in both technical and social contexts. The mining system offers 3 different options, each with its decision-making mechanisms that contribute to the ecosystem.
