Cryptocurrencies Carpet: Moin consensus mechanism insurance
The world’s off Crypto currency exploded when the last day was launched. Persons. The result is fundamentally different mechanisms of consensus that power is there in digital currencies, Nosy in its trucks and west. In this article, we will engage in the popular mechanisms of consensus: Proof Off Off Work (POW) and Proof Off Stake (POS).
Proof from work (POW) *
Prove that the employee removes these consensus algorithms cryptocurrency. Bencoy’s protocol was Ben for the first relationship in 2009.
How does it work
In Pow, Mountains Competition to solve complex mathematical puzzles related to:
- Magn function : Mountains must find a bag that meets the CERT criterion.
2.
- Inspection : Other block knots check the block by solving the puzzles themselves.

POW offers the advantages of the system:
* Energy Effect : Pow Relly Low Energy Expediture, making it more environmental consensus mechanisms.
* Security : Casual puzzles do not make it easy for the attacker to predict the exterior and run a 51% attack on your thyk.
* Speed : POW blocks are created and checked by a fast pace that POS.
Disadvantages
POW always has several drwacks:
Energy consumption : Cryptocurrency energy is important, contributes to climate and strains local power grids.
* Centralization
: There is a powerful hardware and high calculation resources related to the operations of the office.
* Vulnerability : POW does not make any heavy 51% attack on networks.
Proof from shares (POS)
The Protection Agency is the popularity of popularity in the latest gene. This is the first introduction to Ethereum creator Vitaliik Buter, and HASSOED was adopted by cryptocurrencies such as Tezos and Cosmos.
How does it work
Validals, inspectors are selected tools, new beds based on Nethers shares Pack in Networker Don’s Havest. The process includes:
1
2.
- BLOCK CREATION : A random selected verifier crashing a new block and broodcasts itwork.
Beenfit
POS offers the advantages of the system:
* energy efficiency : positive energy when its power is low, making it more environment.
* Security : Therapeutic selection process differs at Atacker processing, which is processed, and run a 51% attack on your network.
* Slower pace : POS creates blocks slower pace that pow.
Disadvantages
POS always a few drwbacks:
* Centralization : It needs to be confirmed that the value is not on the network, as more persons of persons also value flu.
* Scalabity Problems : POS is still at different stages, so Lestan can do so.
Comparison
| Consensus mechanism Energy consumption (kWh) | Block generation time (seconds)
| — | — | — |
| POW | Low to moderate Fast (10-30 seconds)
| POS | Average (2-5 kWh/million) | Slowness (1-3 minutes)
Conclusion
Choosing between proof works and proof off shares.
