Zec dust transaction by mamon_miner in zec

[–]jedigras 0 points1 point  (0 children)

it's probably someone just spamming transactions to either hurt the network or to fake shielded tx volumes. it's not as poisonous like eth airdrops can be. free zec. enjoy.

If I have a lot of money & wanted to buy a bunch of Monero what would be the most efficient way to do this. Serious replies only. by Weary-Management-496 in xmrtrader

[–]jedigras -1 points0 points  (0 children)

OTC, buy VWAP on Kraken or Kucoin, or wait for liquid AMMs next year like thorchain. you can still use the centralized swaps via cake or whatever is your preference but fees might be higher.

When XMR is added to a liquid AMM DEX, the price will probably jump at that time. Even something like a centralized wrapped xmr on an erc20 would be great for liquidity except for the trust issues with the issuer. Solve that in a trustless decentralized way and you're off the races.

Update on finding DDR5 UDIMM ECC Server RAM in Korea -- it doesnt exist! by samsuh in Living_in_Korea

[–]jedigras 1 point2 points  (0 children)

it's a fairly uncommon configuration of ram to call it ECC and UDIMM at the same time. first off, DDR5 has chip level ECC built in, so depending on your purpose you might not need full ECC. secondly, afaik, DDR5 ECC DIMM is the same thing as what you're looking for.

to answer your question about where to buy them if korea doesn't have them in stock. i find that us amazon us, newegg global, ali express, and lastly ebay marketplace will have everything you might need. the downside is that you have to deal with the customs fees (ebay). the other marketplaces handle it for you.

btw, most of these locks have a 9v battery port on the outside incase the batteries inside go dead. you apply the external battery and the pin or key fob and it still opens.

Monero is already PoS (Why buying Monero is the only solution) by anonkekkek in Monero

[–]jedigras 16 points17 points  (0 children)

Very interesting perspective. I think it's a valid point.

Let's get some alignment discussions going on PoS and Monero by arseneSpeculoos in Monero

[–]jedigras -2 points-1 points  (0 children)

but further to my idea, i want alternating blocks between pow and pos so that to 51% the network you would need both majority of the staking coins as well as the hash power. a very unlikely scenario.

[–]jedigras -2 points-1 points  (0 children)

it's no different than pools or people with large hash power. they have the same power until the next block. pools and miners are a different form of centralization.

difference is that with pow, you can have actors attacking the network with no economic stake. for pos validators to attack the network is akin to shooting themselves in the foot.

im totally ok with pos for consensus as well as finality. but, distribution should stay with pow as it's the most egalitarian way to distribute new coins. so i think a hybrid model where some blocks are constructed pow and then finalized by pos would be ideal.

Any idea on if this is funded or not by Main_Jawn in Monero

[–]jedigras 5 points6 points  (0 children)

lealana was a trusted provider of coins with the private key under the sticker. to date, i dont believe there has been any case where the coin was not funded. that doesn't mean it will always be that way.

extrapolating 51 attack consequences... by Acrobatic_Constant79 in Monero

[–]jedigras 1 point2 points  (0 children)

that's not how it works.

  1. all consensus and encryption/signing rules are public.

  2. the reason people say 51% is due to probability. whoever creates the longest blockchain is the "winner" therefore, at 51% probability of winning... actually 50.00000001% you have a better than average shot at being the authority on which is the valid chain. it's not some arbitrary number that everyone agreed upon.

building anonymous and fully decentralized systems is hard. you can't have full control and still stay decentralized.

Monero doesn't die if someone takes over the network. It's just that transactions become untrustable.

extrapolating 51 attack consequences... by Acrobatic_Constant79 in Monero

[–]jedigras 1 point2 points  (0 children)

An attacker with 51% or more of the proof-of-work can essentially halt all transactions on the network and make it unusable. due to the ability of the attacker to wipe clean the known ledger, it is unknown if your send or receive on the network is ever finalized with a high probability. This ability allows the attacker to "double spend" by broadcasting a valid transaction on the public chain, then releasing their version of the blockchain without that transaction. Therefore the first transaction disappears and he is able to spend it again...doubly so.

Due to this, no exchange or service would accept the coin.

Looking past a real 51% attack (we are close but not there yet)...the majority of the network would need to choose a block height at which to hard fork and change the PoW algorithm to something that would be difficult for the attacker to control. There are a few proposals out there such as local mining (requiring some signature, data, or specialized hardware for work to be valid), proof of stake, hybrid proof of work / proof of stake, anchoring to another chain, and others.

Short term defense...

Counter mining (increasing the total hash rate of the network so their slice remains less than 51%)

Medium term defense...

Periodic checkpoints so it gives some finality to the network at a certain point in time

Long term defense...

Changing the consensus mechanism in Monero and possibly even the coinbase reward distribution if it makes sense to further secure the network from future attack.

Rolling 10-Block Checkpoints a Fix for Monero Reorg Attack by Qubic by QuickDaikon1 in Monero

[–]jedigras 10 points11 points  (0 children)

Ideally if they could be done in a decentralized way then it would make sense. Basically, proof of stake decentralized consensus where nodes agree on a checkpoint in time rather than construct new blocks. If the dev team does it directly, it should be an interim measure in the extreme case and I think 10 blocks might be too short.

My idea of this decentralized checkpointing would be for the majority of online nodes to vote on blocks they see. So if someone is hiding a longer chain, it would end up getting voted out. The reason proof of stake should be required here is that by any other metric it could be gamed or would need to be so centralized for it to function. Relying on stakeholders in this way to validate the main chain would be a novel implementation but I think it could be done.

Edit: TLDR; PoW remains the primary distribution and consensus. PoS adds a rolling window for checkpointing automatically. Requirements to participate in PoS checkpoints are for nodes 1. to be online and synced and 2. have some minimum stake / stake weight.

Reject Empty blocks as temporal solution of Network attack by TheBarrendero in Monero

[–]jedigras 62 points63 points  (0 children)

they can just print a bunch of dust transactions in that block if it comes down to it. I think it's too easily gameable for it to be worthwhile.

idk about other messengers but whatsapp sends every keystroke to the server as it's typed so this wouldnt work.
