Discussion about Primecoin and its infra. Primecoin is a very innovative cryptocurrency, being the 1st non Hash-Cash PoW crypto, naturally scarce (not artificially), with very fast confirmations (1min), elastic readjusting reward & a useful mining (byproducts are primes). Primecoin is sustainable (miners are guaranteed to have revenues), and decentralized (ASIC/FPGA are not particularly advantaged). Sidechain for decentralized data applications (e.g. Storj) currently in development.

Bitcoin is the currency of the Internet: a distributed, worldwide, decentralized digital money. Unlike traditional currencies such as dollars, bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. As such, it is more resistant to wild inflation and corrupt banks. With Bitcoin, you can be your own bank.

Maybe you are already familiar with bitcoin, then you could just jump to this article.

Primecoin is an interesting new concept similar to bitcoin, but instead of wasteing all this computing power on SHA256 hashing, Primecoin is generating long and longer prime chains as more computing power joins the network.

Read about it on r/primecoin

I would love to answer your questions as far as I can.

‎1- Primecoin‬ is the First non Hash-Cash PoW Crypto-Currency.

  • "Primecoin is the first to show that a proof-of-work algorithm could exist to compute things other than cryptographic hash functions."

2- Naturally Scarce

  • Primecoin‬ is naturally scarce (not artificially) -no hard limit and this is crucial for its long term continuity and its ability to adapt to market conditions.

  • According to the last estimations, the total supply is going to be ~55 Millions XPM. (peercointalk.org) You don't have to worry about inflation, neither facing blunt deflation (encountered in bitcoin/litecoin)

3- Very fast confirmations - 1min/block

4- Elastic supply

  • ING economist: "A bitcoin algorithm needs to be developed that smoothly matches money supply & demand"

  • This is hard-coded in Primecoin: difficulty going down gets corrected upwards because miners are encouraged to mine, having more reward subsidy.

  • When difficulty is dropping (i.e. miners leave the network), reward-revenue is recalculated upwards so that they come back in, ensuring the network security elastically vs price bumps.

5- Primecoin is sustainable

  • "Primecoin does not use a fixed cap money supply model like bitcoin as described in the primecoin paper, instead its mining output is associate with Moore's Law. It should have much slower drop of mining subsidy than bitcoin in the longer term (10+ years) thus much less affected than bitcoin in terms of risk of low security level. If Moore's law stops at some point then primecoin block subsidy would become relatively constant, rather than tending to zero as in the case of bitcoin (note though primecoin inflation rate is still tending to zero)."

  • "When the proof-of-work mint rate approaches zero, there is less and less incentive to mint proof-of-work blocks. ‪‎Bitcoin‬ is insecure."

  • "Primecoin‬ has still good scarcity property similar to gold while network security is maintained without the need to raise transaction fee."

  • "Long-term ‪bitcoin‬ security relies mainly on transaction fees. ‪‎Primecoin‬ realistically would continue to have some subsidy long term, so is less reliant on transaction fees for security."

6- Primecoin is currently the “fairest” coin to mine

  • "The Primecoin algorithm is ASIC/FPGA hostile, and even GPU mining is not economically viable at the moment. While it is certainly possible to create specialized mining equipment, it is far more difficult and expensive to develop chips for high speed modular arithmetics. In contrast to SHA-256/Scrypt mining, those chips would also be multi-use and could be applied for other purposes after the next generation hits the market. In a sense, Primecoin is currently the “fairest” coin to mine, as it is purely CPU/GPU based. [...] Besides this, Primecoin already offers a number cloud mining providers, which inevitability will be the final stage in the specialized-mining-chip-race. For example, ASIC supplier KnCMiner recently announced not to produce mining rigs for household use anymore, as non-industrial grade power supply is not sufficient."

7- Primecoin can introduce new participants to the new digital economy

  • "In a Free Market, there's Free Will (and Creativity) as driver for Actions - and fundamentally ‪‎Primecoin‬ (almost philosophically) provides us with the ability/choice of applying our Ingenuity on Mining."

  • "With ‎Primecoin,‬ people who like to mine cryptocurrencies have a better choice to mine, to get more benefit out of the mining activity & environmental cost."

  • "Primecoin complements the goal here as it produces additional scientific value from the consumed energy. So people who like to mine cryptocurrency for whatever reason have a better choice to mine, to get more benefit out of the mining activity and environmental cost."

  • With Primecoin, you can actually and effectively Innovate and Improve on Mining Technologies and Techniques, on 2 lines: Hardware and Software. This is radically different from hash-cash PoW. In essence you have twice as much possibilities to earn revenues.

8- Proof-of-work cryptos will gradually transition toward energy-multiuse, ie providing both security & technological computing values. And Primecoin is the pioneer in this realm.

  • "One year after primecoin's public debut, the cryptocurrency designers are still focused on mixing hash functions with hash-cash proof-of-work, or finding ever more 'cpu friendly' proof-of-work; Primecoin's unique proof-of-work remains the first and one of the very few useful and actually interesting proof-of-work designs, that preserves the decentralization property of cryptocurrency."

9- Primecoin has anti-centralization features

  • Brute force hashing random numbers, under rigid guidelines(the more CPU, the stronger) doesn't work to mine primecoins - there's no known rules to find prime chains.

  • Elastic reward re-calibration, in real-time (reward gets immediately lower if difficulty would happen to rise)

10- Primecoin captures the Wasted Energy of Bitcoin's Algorithm - The mining is actually useful

  • "The reason why Primecoin-like “useful POWs” are the most promising is that, if the computations are useful enough, the currency’s “waste factor” can actually drop below zero, making the currency a public good."

  • "The innovative prime proof-of-work in Primecoin not only provides security and minting to the network, but also generates a special form of prime number chains of interest to mathematical research. Thus primecoin network is energy-multiuse, compared to bitcoin network. Primecoin is designed to sustain a prosperous mining market and high level of security, while maintaining good scarcity property like gold. Primecoin also processes payment transactions 10x faster than bitcoin network."

  • "Primecoin's proof-of-work is still pretty much the only alternative proof-of-work in production other than hashcash. By alternative proof-of-work, is meant alternative proof-of-work consensus. Interestingly, Primecoin also tries to address bitcoin's energy problem, from a different angle. In a free market, there is bound to be [the] coexistence of energy intensive currencies and energy efficient currencies, meaning, people have free will to consume energy to produce currency for example, mining gold. So Primecoin would demonstrate, such energy consumption can be made energy-multiuse, while preserving the critical decentralization property."

11- Primecoin has direct by-products

  • "Bitcoin hashing or mining provides no meaningful by-product whereas Primecoin delivers the chains of prime numbers. Primecoin is the first cryptocurrency with such property."

  • "Prime numbers are very useful. They are important in cryptography, and used in many encryption systems. The larger the list of known primes grows, and as the value of the numbers increases, the security of encryption methods utilizing them improves. Understanding prime numbers is also very important for high level mathematics, physics, and engineering. All non-prime numbers can be constructed from two or more prime numbers, yet a prime number itself cannot be created from any other number. Prime numbers are the building blocks of math. The more we understand about primes, we more we understand about mathematics. The more we understand about mathematics, the more we understand about the universe, and everything in it."

  • "For example, Primecoin provides financial incentive to these math research (e.g. research about the twin prime conjecture), if your theory advancement can provide a better mining algorithm for Primecoin mining. Twin prime is a special case of bi-twin chain. A bi-twin chain of length two, that is."

  • "With Primecoin, it's possible to do a proof-of-work consensus other than hashcash and have potential math research along with the fact that FPGA / ASIC development incentive may lead to problems being solved that have never happened before. It's possible, when you have ASIC primality testing chips, the computation capability in these fields would make a giant leap. That could also indirectly help theoretical research."

  • "Primecoin has delivered. It now holds 5 out of 21 world records in simultaneous prime numbers."

  • 2 potential direct applications of the prime chains from Primecoin network:

  • Banking on Prime Numbers The prime number chains discovered by the Primecoin network may ultimately make RSA Encryption - and therefore banking in general - more secure by contributing longer prime numbers to use for RSA Encryption; the longer the prime number, the more difficult it is to "break" the encryption.

  • Hardware Testing & Innovation Since the early days of computing, programs for discovering prime numbers have been developed as a way to test new hardware These by-products include improved computer processors and hardware components, which can be applied to improve computer models used in the science, medical, and engineering industry.

12- Primecoin has been developed by Sunny King, one of the most talented crypto-technologists of the rank of Satoshi Nakamoto

  • Sunny King along with his team continues to grow Primecoin network and is currently developing a Sidechain technology for Primecoin, that is a common infrastructure to make it easier for developers to create decentralized and distributed data applications (of the sort of: namecoin, storj, peershare, datacoin )
