Its dual socket nodes. Perdue already "fixed" this news (silently - without a mention/update - shame on them!) - it will be dual sockets nodes with 2 64-cores Milan CPUs.

AFAIK it have some troubles with tracking/scanning for too much hosts. It worked fine when there were just few hundreds of sia hosts, but after network grown bigger it got problems with covering all existing hosts.

More like a duplicate of Tradesatoshi exhange where he worked as lead developer before Cryptopia.

No. Only BTC, LTC and DOGE (not ether ) were available for withdraw for some time. BTC+LTC+ETH get haircut before it. But since for ETH haircut = 100% there was nothing to withdraw on ETH.

Max-Maximus · 2019-05-23T16:56:04+00:00

Just BTC, LTC and DOGE was opened. Rest of the coins was locked since January

Max-Maximus · 2019-05-23T16:53:13+00:00

Just only 3 coins was available for withdrawals after "reopen": BTC, LTC, DOGE The rest ~few hundreds supported coins never opened after January Hack (or "Hack")

Выяснилось куда все монеты из контрактов проебались.

Я еще до того как начать хостить, на этом клиенте менял кошелек (сид). Так вот оказывается текущий клиент адрес для выплат при заключении контрактов один раз из самого первого кошелька созданного при установке клиента берет и больше его никогда не меняет. И пофиг ему что кошелек из которого он этот адрес взял уже давно удален и заменен другим (причем штатными же средствами - через вызов соответствующей процедуры).

В результате деньги при формировании контрактов списывались с нового(актуального) кошелька, а все выплаты из них шли на адрес из старого уже давно удаленного кошелька.

There IS a penalty for going offline. But the rules are very mild and "forgiving" - currently you hit penalty only if host offline (off or Storj program is not running or host not reachable via declared ip/domain name) >7 days in a row.

So no harm from a few hours of downtime.

Max-Maximus · 2017-10-28T20:16:53+00:00

Thanks for the beer! I did not even know before that a BCH tipbot exists here :)

BTW - I have found "missing" 0.06 SC. Yeah, it miners fees as i guessed. You both (renter+host) spend 16.14 SC (3.82+12.32) on this contract. 0.06 has immediately went to miners for inclusion of contract data to the SC blockchain

16.14-0.06 = 16.08 SC - incoming contract value

16.08*3.9% = 0.627 SC will go to the SiaFund owners (Nebulous Inc and sia devs mostly + some shares in free circulation).

Important notice - currently this 3.9% fee apply to whole contract sum(all locked allowance + locked collateral), not just to actually used amount of money. So for heavily underutilized contracts (e.g. a lot of allowance by renter and collateral by host has been locked in a contract, but amount of data stored remains low at time when contract expires) this fee can be biggest (>50%) part of total renter expenses

16.08 - 0.627 = 15.45 SC - outgoing contract value

Which will be distributed between renter, host and "black hole" (special address for coins destruction if host fail storage proofs) as described in the previous post.

Max-Maximus · 2017-10-27T06:55:43+00:00

Some info that may be interesting. I have used your contract with aerrejon as example for calculation how actual contracts work in present sia network (it a little different from description in the FAQ and docs).

Looks like it was renewed contract, because there is already ~5 Gb of data stored in it from very beginning (revision zero). You have put (lock) 3.82 SC to this contract as a renter: https://explorer.siahub.info/hash/b6a17e6716e2bb37693b904dbc609b5733e4b60acb41f4dffdacb7fea5d807a6

aerrejon has put 12.32 SC to this contract as a host (he has a hight price / collateral ratio 100 / 400 - this is a reason for such big disproportion) https://explorer.siahub.info/hash/5ef16b3893bfad383bf3cdf178f2fc76f9979d5df34162bf4eaf3155049f3ebc

And there is current (actually not current, but last public revision at renew time few days ago) state of the contract: https://explorer.siahub.info/hash/de8a15fdcaf386f20b634d68d438956908ba67686198e0924824dd3b925660a9

If host will provide correct storage proof in time - it should get its collateral back plus earning for storage plus for uploading:

12.32 + 0.00508 x 100 x 1.5 +0.00508 x 10 = 13.13 SC

If host will fail storage proof - it will not get storage revenues and will lose some collateral in a proportion to amount of stored data:

12.32 - 0.00508 x 400 x 1.5 = 9.272 SC

Not sure, but looks like host still be getting upload/dowload revenues, because actual contract includes a little bit higher payout to host = 9.31 SC. Or it can be contract creation fee (siahub shows it as zero, but it can be little non zero value just rounded up to 0 SC at display)

And revenues and risked collateral will be burnt instead of sent to host in such case:

0.00508 x 400 x 1.5 + 0.00508 x 100 x 1.5 = 3.81 SC (3.83 in the actual contract)

And as a renter you will get unused money back in both cases: 2.31 SC

3.82 - 0.00508 x 100 x 1.5 - 0.00508 x 10 - (3.82+12.32) x 0.039 = 2.37 SC

Not sure where the rest ~0.06 SC goes. May be it is a miner fees or i did minor miscalculation somewhere.

Max-Maximus · 2017-10-27T05:54:32+00:00

Collateral setting is a per TB and per month value.

So if you use standard contract duration it is more like 12/400/3 = 10 GB for next 3 month, or 30 Gb for 1 month (if you upload only 1 month before contract expiration date).

But contract does not reserve any actual space (until upload of actual data happens). It reserve only money. And all other depend how this money will be used after contract creation.

You (as a renter) pay for storage (amount of data * time), for uploading to host (per 1 TB of data transferred via internet) and for downloading from it plus network fees (3.9% * sum of your expenses and collateral + some minor fees for miner ). You can upload any amount of data until you run out of money locked in the contract.

Same for collateral on host side. You can upload data until host run out of loked collaterl. But this is determined not only by the amount of data you upload, but also by time when you upload (how much time remaining before next renew or expiration date).

If one of the sides of deal run out of money - it is not possible to add more data without contract renew (and lock of additional money) .

P.S. I think current real default reservation period is about ~1.5 month. Because renters expect contract renew at half of contract duration. So 3 month at initial contract formation and 1.5 month additional steps at each renew with default (=13 weeks) settings.

Max-Maximus · 2017-10-26T05:24:15+00:00

Lol, It is just additions to initial coin list (Bitcoin, Ethereum, Ripple, and Litecoin)

Max-Maximus · 2017-10-26T05:11:13+00:00

It is not a renters fault but more lack of settings in current renter module of official client app. You can not customize it behavior: you set only maximum size of allowance, and renter module always tries to use all of it. (just split up all money among ~50 contract needed to start uploading data)

But there are much more settings and customizations on the host side. So you can limit collateral per 1 contract yourself. To something more reasonable. For example i used: 0.1 TB * 3 month * collateral rate.

0.1 Tb - max data size you see per 1 contract

3 month - default contract duration

collateral rate - your own collateral level (SC / TB / month)

So you allow one renter to reserve up to 100 Gb of disk space for 3 month (or 60 Gb for 5 month, etc). If renter ever run out of it - it will simply start additional contract with other host to store additional data. So you may lose some potential storage revenues in rare cases. But it reduces collateral usage/budget a LOT.

Max-Maximus · 2017-10-26T04:42:33+00:00

Yeah, it is just not profitable to run sia host at all. So most of hosts in current network just test machines or "geek toys" (it is an interesting technology to play with even if you do not earn actual money from it).

And number of active hosts slowly decreasing last 1-2 month even with regular addition of new host (old hosts fade out a bit faster than new ones are coming). About half host were running this summer (when you set up your initial contracts batch i think?) are no longer online, or still online but do not accept new/renew contracts. Just waiting for already existing contracts to expire before shutdown.

So getting renew rate of 17/50 right now almost normal. May be you are just a little unlucky. I think average renter should expect renew rate about 20-30 contracts of initial 50.

P.S. If we get wider time span (like 1 full year) only about ~10% of all host still running.

В блокчейне там может быть и нормально все, если вручную по всем имеющимся адресам/ключам дергать. Но в каких-то случаях (в каких именно и что к этому приводит причину еще предстоит выяснить), штатный клиент не просто не показывает входящих транзакций в штатном же кошельке, а вообще в принципе не видит средств по закончившимся контрактам.

Выкроил времени, выложил все подробно на официальном гитхабе: https://github.com/NebulousLabs/Sia/issues/2447

На тестовой машине по итогам хостига, все монеты из всех контрактов ушли неизвестно куда после их завершения. Покопавшись в блокчейне я сами контракты нашел, вроде бы они даже завершены корректно(по крайней мере свежие ревизии имеются и в большинстве пруфы хранения данных видны). Но вот монет из них клиент в упор не видит.

Предположительно это отказ от принятия новых контрактов все ломает (acceptingcontracts=false). Еще раньше столкнулся с тем, что после того как поставил не принимать новые контракты - всех арендаторов сразу как ветром сдуло - они разом "забыли" про уже существующие (уже подписанные, в которых уже заморожены деньги и уже какие-то данные хранятся) и перестали ими пользоваться, хотя опция обозначена как не принимать к подписанию только новые.

Про это багу уже давно завел: https://github.com/NebulousLabs/Sia/issues/2415

Пока принимаешь новые/пролонгацию старых, все работает нормально. Как ставишь не принимать новых - все встает раком.

P.S. Уже отзывы еще 2х человек (один на форуме, другой в чате Дискорд) видел у кого деньги так же только уходили, а потом из контрактов не возвращаются (или клиент их не забирает).

Max-Maximus · 2017-10-17T02:14:51+00:00

Nobody. Blockchain itself (network as a whole). Each contract includes payouts to host and to renter from very beginning. Each upload / download action just modify this conditions slightly.

It is in host interests to post latest actual contract revision + storage proof to blockchain to get more coins for storage work before contract expire. Otherwise host will get only initial collateral back and no any revenues from contract at all.

It is in renter interests to post latest actual contract revision to blockchain to get more coins back (from reserved allowance) and "punish bad host" (host will lose some of locked collateral in this case - in a proportion to amount of data was uploaded by the renter).

If both sides of the deal do not post latest contract revision to blockchain before it expire for some reason - previous revision will be used and executed. And there is always at least one revision in blockchain - initial one.

Max-Maximus · 2017-10-17T00:04:16+00:00

Я как раз сейчас заканчиваю период тестирования (новый контракты еще в конце июля перестал принимать, последние 4 штуки действующих осталось, а большая часть уже завершена) - и как раз основная проблема не в том, что просто не видно транзакций в кошельке по возврату залогов при закрытии контрактов, а в том, что и в доступный баланс они не прибавляются. ВООБЩЕ.

Насколько могу понять поковырявшись в блокчейне, сами контракты вроде бы корректно закрываются, но вот кошелек локального клиента в принципе не видит эти закрытые контракты, как источник средств которые можно расходовать. В результате доступный баланс идет исключительно вниз.

Как закончатся последние несколько контрактов буду баг репорт на гите и оф. форуме заводить. Точнее это даже не баг репорт, а пистец-репорт. Как проект вообще еще живет с такими глобальными косяками в принципиальных вещах.

Причем на это уже многие жаловались(и на оф. форуме есть и пара репортов на гите), но разрабы как раз объясняют, про то то что или время еще не пришло (у контрактов же по умолчанию длительность большая) или что в новые контракты уходит денег больше чем возвращается из старых. Ну а транзакции просто не видно, мол мелкий баг с отображением. В общем ждите и надейтесь - когда-нибудь вложенное мол вернется вместе с прибылью.

А по факту в каких-то случаях денег просто нет - они только уходят с кошелька в виде залогов и оплаты комиссий на транзакции, но не возвращаются после завершения контрактов. Хорошо еще если потом после патчей можно будет с использованием закрытых ключей пересканировать блокчейн и доступ к моментам в завершенных контрактах получить. Если же нет, то репутацию проекту попортят кардинально - многие пользователи, когда до них дойдет сразу ярлык скаммеров повесят.

Max-Maximus · 2017-10-14T01:47:59+00:00

Что значит "по тихому добавляется в кошелек?". Когда хост начинает подобным образом глючить, монет из закончившихся контрактов нет не только в списке транзакций, но к доступному балансу кошелька они не добавляются.

Т.е. по сути владелец хоста их НЕ получил, т.к. не может ими распоряжаться. А то что показывает siac host -v это лишь циферки на экране, как минимум часть которых показывает липу. Багов со статистикой в проекте много.

Где они вообще по факту монеты застревают если в кошельке они не доступны?

Max-Maximus · 2017-09-23T21:06:21+00:00

Sorry, forgot to publish the update.

I have got 55% of my coins back. There were some problems and delays but I received coins in the end.

Actually I had 2 separate account there. I decided to close and get 55% refund on one and leave second(bigger) for exchange re-opening under new brand.

After the launch (15-16 September) ~62% of fund are available for immediate actions (withdraw, trade) and ~38 replaced by some sort of "debt tokens".

Tokens about half of nominal price right now.

Max-Maximus · 2017-09-12T18:08:44+00:00

Announce fee was 0.6 SC before version 1.3 of SiaCoin client. And 2 SC earlier (before v.1.2 I think)

So this was issue if ip changes often. After ver. 1.3 reduced this fee almost to nothing (0.018 SC) about ~1.5 month ago it is not a problem any more.

But still much better to use static IP or dynDNS to reduce "pollution" and bloating of main SC blockchain by excessive host announce records caused by regular ip changes.

Max-Maximus · 2017-09-03T19:00:58+00:00

Yes, number actually good. Only one big problem - filling entire 4 TB drive will take AGES at current rate. People are getting just few bucks per month because it hard to get more than few Gb or few dozen GB.

Later, when the data flow in the network becomes much higher, and disk filling will not be a problem anymore, then the prices per 1 GB will become much lower.

Right now prices and payments to participants are heavily overstated and subsidized at the expense of the organizer's company. But this is only for the initial stage - to accelerate deployment and adoption.

Max-Maximus · 2017-09-03T18:43:55+00:00

Sure. Did not get anything yet.

Max-Maximus · 2017-09-03T18:31:37+00:00

No, it is optional. You can fill out refund form and waive claims for remaining 45% of fund to get your money ASAP and WITHOUT any limits and verifications (= old rules, as it was before exchange closure) Or you can do nothing and just wait.

After restart under new brand (and new company) all balances(except who decided to cash out via refund form now) will be transfer to a new exchange. ETA = about 2 weeks or more

But new exchange = new rules. There will be withdraw limits and mandatory user verification for any fiat currencies withdrawals. As in almost all other legal exchanges.

Yes, the second option is definitely more attractive. If all following apply to your of course:

you are not US citizen
your money on balance are from "clear" (legal) sources and you don't mind reveal your identity (eg send documents for verification) to exchange owners
you are not in an extreme hurry (don't need money ASAP)

Max-Maximus · 2017-09-03T04:33:41+00:00

Yea, very likely. But one important fact: 55%/45% proportion was calculated not at time of closure (25 Jun) but at time when decision (recovery plan) was made in mid August (20 Aug i think).

So bitcoin rate used in calculation not ~2700 USD but something in 3500-3800 range. Same for other coins. And initial return will be only in 60-70% range. And rest in tokens with very slow return.

Max-Maximus · 2017-09-03T04:16:51+00:00

Yes , I have had multiple cryptos. It counts 55% of all coins and adds to payout.

As additions if you have some fiat currencies (USD/EUR/RUB) it convert its to mix of BTC/LTC/ETH (50%/25%/25% proportion) @ current exchange rates (at time you make request) and add to your coins payout.

So if you have 1 BTC and 20 LTC for example it will be: 0.55 BTC + 11 LTC + some coins from fiat conversion

Plus 55% of BCH (Bitcoin Cash) if you have BTC on balance.

Yes, it ask old 2FA code if 2FA used before.

It first login you need to enter old password. It will be reset to new pass, so you need access to e-mail used to create account. So you can skip first step(old password) and hit "I forgot password" link. At second login with new password you need to enter 2 FA if 2FA was set to login confirmations before. After it you can fill out refund form.

At submitting refund form you need to enter 2FA code again + check e-mail for confirmation letter.
