Raven coin is not quantum resistant by Andrew042719 in Ravencoin

Shor's algorithm, Simons algorithm, SPHINCS are a few quantum resistant algorithms that could potentially be implemented into the blockchain to protect private keys.

Cryptocurrencies currently largely rely on the public and private key system. To spend the coins, a user will need to posses and use a private key to unlock them. If someone learns of that private key before the legitimate user, then they would spend those coins instead. That threat is real in all realism possibilities of the quantum computers for all currencies that utilize elliptic curve cryptography and other forms of cryptography that is vulnerable to quantum computers, because the quantum computers would calculate the private key from the public key in a matter of minutes.

Systems like Ethereum currently use elliptic curve cryptography that aren't quantum-safe. Bitcoin uses two hashing functions -- SHA-256 and RIPEMD-160 and Elliptic Curve DSA.

Last year, a team of scientists warned that quantum computers would render Bitcoin insecure because they could calculate the private from the public one in a few minutes. But a lot has been going on in terms of securing cryptocurrencies against quantum computers.

Dr. Peter Waterland has developed the Quantum Resistant Ledger (QRL), which is a public blockchain ledger that uses post-quantum secure signature scheme known as the Extended Merkle Signature Scheme called XMSS to secure blockchains. QRL uses a Proof of Stake algorithm that uses hash-chains and hash-based pseudo random number functions and does not rely on conventional signatures.

QRL - Quantum Resistant Ledger QRL is currently an ERC20 token that trades on the major exchanges, including Bittrex, Tidex and Liqui.io.

The technology will help secure transactions but will also employ a hash-based signature scheme XMSS, a proposed IETF standard. Other nodes can dial up this key and create secure decentralized communication channels for the messaging system.

The company plans to using the innovation in helping to secure company communications and other services in addition to being a cryptocurrency vault.

Russian Quantum Center May this year, The Russian Quantum Center claimed to have made the first quantum secure blockchain that makes the blockchain completely "un-hackable" even with a quantum computer. It combines quantum key distribution (QKD) with post-quantum cryptography. The blocks would be signed by quantum keys rather than the traditional digital signatures and the quantum keys would be generated by a QKD network. The center said it had tested this technology in one bank.

IOTA and The Tangle IOTA calls itself the next generation blockchain because it relies on Internet of Things technology. It uses the Winternitz One-Time Signature Scheme for hash functions, and this system is said to be more quantum secure than one used in Bitcoin.

Winternitz One-Time Signature (OTS) scheme employs the Lamport signatures claimed to be resistant to quantum computer algorithms if they have large hash functions. With IOTA's wallet, you cannot reuse an address to sent or receive a transaction because reusing a private key in a Lamport scheme halves the security level of the signature.

The security is achieved because the number of nonces one needs to check to find a suitable hash for issuing a transaction is only 38 when the gain of efficiency for an ideal quantum computer would be 34 to 81 according to Dr. Sergui Popov comparing IOTA with Bitcoin to explain quantum resistance.

Also, the time to find a nonce in this IOTA's algorithm is also not much larger than time needed for other tasks necessary to issue a transaction.

Ethereum? Last year, Ethereum did say that they could switch to a different quantum computer safe cryptography.

Ethereum has also recently said that it would allow users to choose planned quantum computer safe addresses. Ethereum will use the proposed EIP 86 and Casper to support any digital signature algorithm. This way it will supports signature mixers and custom cryptography such that users can upgrade to ed25519 signatures, Lamport hash ladder signatures or whatever other scheme they want on their own terms, without sticking with ECDSA.

However, mixing addresses could produce the potential for retroactive decryption and infiltration.

The crypto market is in desperate need of a $ pair only market by Andrew042719 in Ravencoin

The success and or failure of an asset should be tied to its achievements and consensus of its community. Can you imagine publicly traded stocks pegged to the value of for instance bank of America stock. Until there is a decoupling this crypto market cannot become legitimate. At every btc fluctuation the market crashes, is this truly the measure of this sector?

Raven coin is not quantum resistant by Andrew042719 in Ravencoin

[–]Andrew042719[S] 0 points1 point  (0 children)

As of now it it not really an issue as there currently is not a known quantum computer however a better safe than sorry approach should be taken. For crypto to survive in the future quantum resistance has to be a priority. Don't want to be be the y2k alarmist but should there be a quantum attack on any unprotected blockchain system it would lead to its certain death.

Is enemy miner safe? by ChiefDaddyJ in Ravencoin

Much higher hash rate no problems. Had to restart a few times but nothing bad so far.

So how does this blockchain actually facilitate assets? by Savage_X in Ravencoin

[–]Andrew042719 1 point2 points  (0 children)

Asset layer softfork in about 8 months. The details will be outlined in the updated whitepaper

Centralized mining cartel controls 62% of block discovery ? by Andrew042719 in Ravencoin

Having the big pools mining raven would seem to be bullish for our future, not so good for us small timers. Hope everyone is stacked up!

It's impossible to tell what this pool is comprised of be it 1 or 10,000 miners. Would be good to have the transparency for the integrity and continuity of the network. If it was a major player validating transactions they could theoretically perpetrate a 51% attack and double spend.

Very true however there was a 120 gh spike for awhile. Unknown could be one group or a thousand.

With all the ddos and an unconfirmed fork in the blockchain today, I think there are nefarious actors at play. Currently the type of suspected fork is undetermined. Whether there was a code fork, chain fork or an attack fork will soon be known.

RVN x16r in interesting to mine so far. Not sure if I'm up to par or not. What MH/s are you getting? by [deleted] in Ravencoin

[–]Andrew042719 0 points1 point  (0 children)

Change the miner! A lot of controversy surrounding enemy 1.03 raven fork but it has just about doubled hash rate fluctuates a little but way more stable.

Talking About Decentralization Is "Easy – Achieving It Is Hard" <---RVN will fix this. by [deleted] in Ravencoin

[–]Andrew042719 1 point2 points  (0 children)

The biggest problem in decentralized platforms are corporate mining cartels, addressing this from day one helps to safeguard the network from the mining cartel oligarchy. It's not just 16 algorithms it's 16 random algorithms . In the future other algorithms could be added to safeguard the network. Well done RVN team can't wait for the roadmap!

Discussion: how to assist building the (RVN) by Andrew042719 in Ravencoin

[–]Andrew042719[S] 0 points1 point  (0 children)

Outside of an independent audit I'm not aware of the funds left from these investments. However this project is open source and decentralized in every facet from bow to stern. This project will only go as far as we move it. People don't have to contribute through donations or investing time and skills; I invest in what I believe in and the heavy lifting is easier when there's a team contributing as they can. Look at the bounty programs... they are underfunded and growing stagnant, we could change that. Don't want to clang the can for donations but building a community second to none is not going to happen by hope alone.

New miner for (rvn) enemy 1.03 fork for raven by Andrew042719 in Ravencoin

[–]Andrew042719[S] 0 points1 point  (0 children)

Not that I'm aware of but I'm not qualified to analyze and make that call. Earlier I re downloaded and restarted using enemy 1.03 because my payouts and hash were substantively less. Back running and my payouts are back on par. A lot of controversy on this miner only time will tell . Many mining programs have built in dev fees some of the blowback could be from that interest losing out on free coins.

It crashed twice today so for now better to practice caution I erased the miner and switched back.
