00:01:34 sadLarry: did you previously have a synced up blockchain? 00:03:12 selsta, I usually used monerod to sync up. Not sure what you are asking. 00:03:47 is /media/monero/lmdb an external hard drive? network drive? internal drive? 00:04:00 internal HDD 00:04:28 I wanted to know if you previously already had a fully synced up blockchain or if you are trying to sync up from scratch 00:05:52 oh, Yes I did fully synced up the blockchain initially. In fact I used nvme to speed up the process. When it finished, I transferred the blockchain db to HDD. Then I simply keep updating it on a weekly bases. 00:06:55 `Failed to parse block from blob` usually means corrupted blockchain 00:07:08 you can try to start with `--db-salvage` but that likely won't help 00:07:16 best to restore from backup or sync from scratch 00:07:42 now why it corrupted, I don't know. did anything happen out of the ordinary? 00:08:14 power failure 00:08:20 I found this: 00:08:21 2023-12-14 01:00:35.716 [P2P1] INFO global src/cryptonote_protocol/cryptonote_protocol_handler.inl:1687 Synced 3024200/3039135 (99%, 14935 left) 00:08:21 2023-12-14 01:01:21.057 [P2P1] INFO global src/cryptonote_protocol/cryptonote_protocol_handler.inl:1687 Synced 3024220/3039135 (99%, 14915 left, 24% of total synced, estimated 11.5 hours left) 00:08:47 After this ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@ 00:09:31 selsta, I doon' 00:09:36 yes that would explain it 00:09:58 selsta, i don't have a backup, or the patience to sync from scratch 00:10:10 best to use a remote node in this case 00:11:37 let me try db-salvage 00:14:33 selsta, same error with db-salvage 00:15:18 power loss during sync means corruption in most cases 00:15:18 but it is just the latest blocks which are currupt. 00:15:46 you can set `--db-sync-mode safe` to prevent this but it means slower sync 00:18:29 selsta, thanks! 00:19:05 Guess I'm back to using remote nodes :) 00:25:14 http://srx.lol 01:57:56 perhaps we should switch the default to safe? better to have a slowly syncd chain than a corrupt one... ? 02:14:53 Isnt it "safe" during initial sync by default? 02:15:10 Hm lol. I think im crazy. I knkw its fast:async 02:15:30 So where am i getting double info from 🥴 02:25:55 `The default is fast:async:250000000bytes` 02:27:05 `safe` will wear on your drives more and sync slower iirc 02:28:35 Is there any email provider that allows payments with monero? Just watched the interview of protons CEO by The Linux Experience and got annoyed there where no mentions of it. 02:30:20 Simplelogin and tuta 02:30:31 Proxysto.re 02:30:52 Tuta allows monero? 02:30:55 https://digitalgoods.proxysto.re/ 02:31:13 > > <@ofrnxmr:monero.social> Simplelogin and tuta 02:31:13 > Tuta allows monero? 02:31:14 Nope 02:31:44 https://tuta.com/support/#cryptocurrency 02:34:43 <123bob123:matrix.org> Proxystore 02:35:05 <123bob123:matrix.org> Trust me bruh 02:35:32 So I will still have to deal with another step... Question what benefits does this have over buying bitcoin with monero and then paying for proton? 02:37:19 What? 02:37:30 <123bob123:matrix.org> With simplelogin you use proxystore and gives you a code and redeem that code with in simplelogin. 02:37:31 using bitcoin for money? 02:37:34 <123bob123:matrix.org> And 02:37:39 Are you a masochist? 👀 02:37:48 <123bob123:matrix.org> Simplelogin support told me to use proxystore lol 02:37:51 bitcoin is gold 02:38:05 You dont spend layer 1 02:38:12 <123bob123:matrix.org> Hodl never sodl 02:38:18 And you definitely sont use custodial LN 02:38:38 <123bob123:matrix.org> Plus simplelogin has coinbase so you can btc 02:38:47 So why monero? Because it has an intended use case, and is the best at it - being money 02:38:47 <123bob123:matrix.org> But its coinbase 02:39:31 Yes. You can btc through proxystore. But again, mempool.space 02:39:35 Are you a masochist? 02:39:53 Id rather not pay $30 surcharge for a $10 purchase 02:41:21 > Id rather not pay $30 surcharge for a $10 purchase 02:41:21 Sorry, only $5 if you want to wait an hour or 2 02:41:25 I'm so confused. This is what I was thinking XMR ---> BTC ---> ProtonMail. You are saying XMR ---> Proxystore ---> TutaNota/SimpleLogin 02:41:38 Im saying 02:41:48 simplelogin is so dope 02:41:50 I use it 02:42:28 I want to know how it's better? I will be dealing with 2 companies if I do the Proxystore route 02:42:30 https://x.com/nahuhhXMR/status/1737261042231558399 02:42:41 pretty sure they allow USDC transactions 02:42:50 ew 02:42:59 Why not just use your bank card 02:43:22 "i like Goldman sachs coin" 02:43:38 <123bob123:matrix.org> Cakecoin* 02:43:51 Backed by less than 1$/1usdc 02:44:10 Also you get simple login if you have Proton Premium 02:44:13 <123bob123:matrix.org> Instead of burning gas i eat the cake 02:44:23 Yeah I have proton premium thats how I do it 02:45:05 So XMR ---> BTC ---> Proton? 02:46:44 I used to have bitcoin when I bought proton premium 02:46:56 sold all of it into XMR now since the fees are too high 02:47:50 Do you still use proton? How do you pay for it? 02:48:03 I paid a 1 year thing once 02:48:05 didnt expire yet 02:48:14 I paid a 1 year thing 02:49:09 https://matrix.monero.social/_matrix/media/v1/download/matrix.org/lkTzvXpgkrFzpePhPQpKAkmr 02:49:24 I just saw this is the monero room and not monero of topic. 02:49:45 How are you going to pay next time? 02:49:46 I paid a 1 year thing and had a deal for 2 years or some shit I dont remmeber 02:50:05 Probably wont if they dont support another payment method 02:50:33 can I buy Giftcards with XMR? 02:50:57 without getting a 10% surcharge***** 02:53:54 So proton will cost more due to the BTC fee and dealing with proxystore will avoid that fee but expose me to 2 companies 02:54:15 If I use XMR whats the issue? 02:54:36 Expose in the sense of any record will be kept 02:55:01 What do you mean? 02:55:28 I use mullvad browser + vpn, pay with XMR, why would using a gift card be any problem ? 02:59:05 Yeah I guess but what is the difference then between that and paying for proton with BTC I bought/traded with XMR for? While also using (Mullvad Browser +vpn)/TOR 03:00:05 I dont pay 50$ cross-chain fee then I dont get fucked with another unreasonable fee when sending the money to proton 03:01:30 fees, confirmation time, and depending on how you traded btc for xmr, possibly a connection to your idenity 03:01:35 fees, confirmation time, and depending on how you traded btc for xmr, possibly a connection to your identity 03:01:56 fees, confirmation time, and depending on how you traded xmr for btc, possibly a connection to your identity 03:02:27 So it's the cost/price. And ofc the differences between the services like Tuta vs Proton 03:02:50 added complexity for the user too 03:02:51 If I used Local Monero? 03:03:02 sure 03:03:55 someone could trace it back to the local monero seller and then ask them to provide the accounts of the users they traded with 03:05:00 what is tuta 03:05:38 I found a sort of CEX where I can just send funds and they send BTC to my wallet, no account needed. 03:05:48 Tutanota they changed names to Tuta 03:05:59 like I send a crypto to it and they send to my other wallet the token I want 03:06:07 I use it to buy monero 03:06:21 their fees are high but whatever 03:06:44 I use MEXC exchange as well which is banned from my country so I dont think they should report me using their platform 03:07:01 sounds like you're describing an instant exchange 03:07:13 its called fixedfloat or something 03:07:15 Yeah but they would get the same if someone traces it back to proxystore 03:07:51 no, you don't need to provide any information to make an order on proxystore 03:08:21 can we create a monero credit card gents? No kyc, just send xmr on it and spend 03:08:24 Neither do the sellers on Local Monero 03:08:45 it would probably be illegal but who cares 03:09:34 uh, at least a username, i guess 03:09:41 not sure about email 03:09:48 Well not if you like this. Seller 1: Fiat ---> XMR Seller 2: XMR ---> BTC 03:10:20 is there a country that would allow us to create a monero credit card with no KYC? I know MEXC and Kucoin exchange as well as all the other CEXs that dont require KYC are located in an island, is it possible there is a sort of bypass? 03:10:23 Yeah a username that can be any random thing 03:10:34 do credit cards from one country work in another? 03:10:47 how many people really use random usernames? 03:11:13 sure, with great opsec you could potentially achieve the same results 03:11:27 Depends but yeah at least in the EU 03:11:27 but what i am saying is that you have to be mindful of the little things and it's a more complex process 03:12:17 The same goes just for buying XMR 03:12:26 no, not really 03:12:46 even if people know that you bought xmr they dont know if, where or when you spent it 03:13:43 Exactly so buying BTC with it is as safe as proxy store 03:14:58 provided you buy the BTC in a completely anon way, sure 03:15:03 does anyone know if I connect my ledger nano S via mobile if I plug it in for cakewallet? 03:15:09 that way I can have monero on the go 03:17:14 I just checked and answer is no 03:23:56 No 03:24:32 Completely anon btc might be dirty / not accepted 03:25:09 good point, but we were focusing on privacy 03:25:31 i also mentioned the differences in fees and confirmation times 03:25:51 but in terms of privacy, i don't think there's a difference, correct me if i'm wrong 03:29:45 Yeah that's what I was thinking too. 03:30:56 Well why wouldn't a XMR to BTC trade on lets say LocalMonero work? 04:02:29 Again, no idea why anyone would even want to use bitcoin 04:02:29 Use ltc 04:03:18 actually, i get all of my ltc from exchanges that do aml 04:03:53 So, fixedfloat, for example, should only give you clean coins - even if through trocador 04:24:21 <9_11_01> how does the number of monero inputs increase? 04:39:02 <9_11_01> or outputs 05:20:22 Learn how crypto work, it's basic like most if not all cryptocurrency (coins, not token), work. 05:20:22 a TX is a mix of output the are boing used in the TX (in that case they are becoming Inputs for the TX). And where you send to, is the output 05:20:23 So you receive 1 "output" each time you receive a TX. 05:20:23 And when you spend you spend the output(s) you have. 05:20:24 They don't merge together, even if sent to the same address. 05:20:24 So if you want to send 1XMR, you will use an output that contain more than 1XMR. But if you don't have that, like you received only TX lower than that, then you will spend enough output for the transaction. then they will be merged so you send one output only to the recipient and a second output, which it the change 05:58:39 just use your wallet on your phone with a trusted open source wallet app 05:58:42 phones are generally more secure than desktop pcs 05:58:52 or make a wallet for on the go use 05:58:53 if you get monero from multiple txs i think 05:58:53 the more txs, the more inputs 07:09:25 What is the green number on the right side above Buy on local monero? 11:37:22 Why is ltc even used 11:53:30 low fees and accepted by more merchants than xmr 12:33:03 hrm. monerod on xmrchain.net running that patch only has a 3 hour uptime, and i definitely didn't restart it 3 hours ago 12:38:18 ermagerd why can't i figure this out from the logs 12:38:56 im using grep -B 6000 synchronized bitmonero.log-2023-12-20-08-58-12 to catch all the crap before the daemon restarted 13:28:13 <9_11_01> so if i do a self send of all coins to 1 address will it merge 13:29:59 Yes 13:30:31 > hrm. monerod on xmrchain.net running that patch only has a 3 hour uptime, and i definitely didn't restart it 3 hours ago 13:30:31 Try w/o systemd 13:30:49 Or a generic one 13:36:27 then if im not watching it xmrchain.net will be unusable... 13:39:23 oh snap. Dec 20 09:51:04 Ubuntu-1804-bionic-64-minimal systemd[1]: MON_daemon.service: Failed with result 'oom-kill'. 13:40:17 so xmrblocks and monerod both running on this 64GB system cause monerod to get oom killed 13:40:42 aight, lets see if release gets oom killed 13:41:27 with no memory management 13:44:53 If you have a bank account: https://dfx.swiss/ 13:52:28 gingeropolous: was that oom with swapiness already set? 14:04:35 <9_11_01> well that aged well 14:04:35 <9_11_01> https://cdn.discordapp.com/attachments/620459189097201669/1187032801485258852/IMG_6213.jpeg?ex=65956971&is=6582f471&hm=d6a83f6b2cb879f89be50404db45b6a7c779756eaf060325942919894e357bc0& 14:10:01 i stopped reading after i saw bitcoin winning in transaction speed 14:21:36 "10min avg" 14:21:36 huh? 14:21:48 No. 10min avg blocks. Not transaction 14:22:27 Avg time til 1 conf is probably like 1hr + lol 14:22:55 If 100% of tx fit in 1 block, yeah, 10mins 14:23:04 Too mad there sre 300 blocks in queue 14:23:17 Bad* 14:26:56 when there's no backlog, avg txn time is 1/2 of block emission time 14:28:26 your longest wait is if you submit a txn immediately after a block was found, then it will be (on avg) full emission time until next block, which can pull in your txn. 14:28:50 and your shortest wait is if you submit a txn immediately before a block is found, and your txn was included. 14:29:11 or, if you submit your txn before a block is found, but it doesnt get to the node finding the next block in time 14:29:18 on avg, you'll be submitting txns half way thru 14:29:29 <9_11_01> 🤓 14:29:29 Iirc no backlog is 1 block emissions time due to gambler fallacy 14:30:01 gambler fallacy? 14:30:11 That... is an interesting observation. 14:30:19 ah, also assumes miners are updated quickly when new txns arrive 14:30:47 Rucknium: did the numbers 14:31:17 If you make stats on all txes, I expect the average time is 5 minutes. But if you take every tx, I expect every one of them has to wait an average of 10 minutes as the mining process is stochatic. One of these things must be wrong. 14:31:37 rucknium measured how the current network behaves, and found it was sub-optimal. but theoretically, all systems running optimally, it would be as I describe 14:31:41 Or maybe "One of these things must be wrong." is wrong... 14:33:47 anyone here know what's the current hardware bottleneck for monero? i know i've asked this before but i don't recall the answer 14:33:57 (for nodes) 14:34:08 is it RAM? network bandwidth? 14:35:06 any of those limits can be moved if you spend enough money 14:35:20 but I suppose network bandwidth is the most difficult to expand on your own decision 14:35:22 Typically, storage. 14:35:38 i mean, which one costs more to scale 14:36:11 i did some napkin math and it seems like since the around introduction of RCT, the cost of storing the entire blockchain on an SSD has been around 5USD 14:36:16 I would say storage is cheapest, which it always is in any computing system 14:36:27 RAM is next 14:36:42 (considering variations in blockchain size and SSD prices) 14:36:58 network bandwidth - unless I pay someone to dig new cable ways etc., I can't buy more bandwidth 14:37:51 and I prob can't even get permission for such a dig. maybe bribery, so more cost. ;) 14:37:56 i mean, if you have a 100Mbps contact but your infra/network provider supports 10Gbps, you definitely can 14:38:15 to an extent, at least 14:39:43 I wanna keep my pruned blockchain up to date on one of my laptops and I"m running monerod with Task Scheduler for 4 hours every night. Windows sends a WM_CLOSE to the process at the end of 4 hours, but I'm worried that the LMDB will get corrupted. Is the default db-sync-mode okay, or should I use safe:sync? 14:39:54 oh, i think i remember someone mentioning that the worst thing to scale would be IO 14:40:09 disk reads/writes 14:40:21 QuickBASIC_: killing the process doesn't matter. the only thing you have to worry about is crashing the OS. 14:40:35 Okay. Thanks hyc. 14:41:31 charuto: you can always buy more storage and set it up in RAID 14:41:50 but most people can't shop around for more ISP access 14:42:46 hyc: that's true, i guess it does scale as well as storage size 14:43:03 is cpu cache relevant at all for blockchain scaling? 14:43:06 Depends what "scaling" means. I thought you meant "I sync my chain, what's the bottleneck". 14:44:33 i meant, if we suddenly had 100x tx/sec, where would the node operators be spending most money to keep their node running 14:44:42 would the costs just scale linearly 100x all around? 14:45:08 if I sync up a new node on my LAN, using a local node as priority, vs a remote node on a distant network, there is a large difference in sync time. so I conclude network is my main bottleneck. 14:46:08 That is unexpected. Typically, monerod ends up with a healthy set of ready block spans rather quickly, so blocks are already downloaded by the time they're to be added. 14:47:26 It breaks down if you have just one peer though, as it flip flops between dl/add, rather than going back to dl after dl and letting another thread add. 14:47:43 hmmm. maybe I was using exclusive node. 14:48:48 i apologize if this has been discussed or suggested countless times, i have not been keeping up with development: but has it ever been considered to scan the chain for outputs as it downloads? instead of the current sequential "first download, then check for transactions" method? 14:49:30 monerod and the wallet tend to fight for the blockchain lock, so the long sought for rw lock change would have to happen first. 14:50:16 and I would think the info isn't trustworthy until you know you've reached the tip of the correct chain 14:51:25 but that's already the case, hyc 14:51:42
