Definition of Obelisk
Obelisk is a specialized blockchain consensus algorithm developed for the Skycoin ecosystem. It is designed to address various limitations associated with traditional proof-of-work algorithms by significantly reducing the need for mining, boosting transaction speeds, enhancing security, and distributing network influence through a “web of trust” concept.
Obelisk vs Proof of Work
| Feature | Obelisk | Proof of Work |
|---|---|---|
| Mining Requirement | Minimal or none | Requires significant computational power |
| Transaction Speed | High speed, immediate processing | Generally slower due to mining verification |
| Security | Enhanced security through distributed influence | Vulnerable to 51% attacks if colluders control enough hash power |
| Energy Efficiency | Energy-efficient, low resource consumption | High energy consumption due to mining operations |
| Consensus Nodes | Separated nodes for consensus and block creation | Miners act as both validators and block creators |
Example Usage
- When a transaction is made on the Skycoin network utilizing the Obelisk consensus, it quickly receives validation through a designated node, rather than waiting for a miner to stumble upon a solution to a cryptographic puzzle.

Humorous Insights
-
“Why did the blockchain break up with the proof-of-work?” Because it found someone more efficient that didn’t require so much energy — obviously, it was Obelisk!
-
A fun fact: Obelisk takes its name from the ancient Egyptian monuments that stand tall and unyielding — much like the aspirations of this consensus to stand strong against the test of time in the blockchain world!
Frequently Asked Questions
Q1: How does the Obelisk improve transaction speeds compared to traditional algorithms?
A1: Obelisk employs separate nodes for consensus and block creation, allowing transactions to be validated quickly without requiring extensive mining efforts.
Q2: Is Obelisk energy efficient?
A2: Yes! Unlike proof-of-work systems that need heavy computational energy, Obelisk facilitates transactions with minimal energy usage.
Q3: Can Obelisk be vulnerable to attacks?
A3: While Obelisk greatly enhances security, like any system, it is not entirely immune to attacks. However, the web of trust aspect significantly mitigates these risks.
