That's simply false. Bittrex has actually been working with the Sia dev team to update their wallet software and correct their issues with deposits and withdrawals, which are working again. Why would they take so much trouble if they plan to delist the coin? Don't listen to the FUD out there.


You can check the table "Top 100 hosts average settings" at SiaStats to get an idea of what the most competitive hosts (thus those that get most of the file contracts) are using for pricing: https://siastats.info/hosts_network.html

There was a hardfork at block 135000, but due to a bug in the Difficulty Adjustment Algorithm, a new hardfork was introduced on software version 1.3.1 to correct it. It will happen on block 139000, around the end of January.


That is absolutely false: the current average block time is 30 minutes due to the bug in the DAA, not 3 hours as you are claiming. So the hardfork will take place by the end of January, no matter what you think. You can check it here: https://siastats.info/mining.html in the last chart. I don't think there is any need to discuss with you your complains and personal opinions about the "confidence" of investors or miners. The "confidence of miners" can be however measured very easily and objectively: it is the network hashrate. And as you can see in the first chart of the previous link, it has actually increased in the past few days.


The blockchain is about 8.5GB big. If you are using SSD disks it will take less than 10 hours to synchronize. If you are using HDD disks it will be several days (2-3 days or more)

There is a hardfork planned at block number 139000, approximately by the end of January. It is aimed to correct the mining Difficulty Adjustment Algorithm.

Take in mind this is a non-contentious fork: all the community, mining pools and infrastructure is accepting it. At such, there will not be a "split" in two coins, no airdrop. The old blockchain will be abandoned.

Each file is stored across 30 hosts with a 3x redundancy, using the Solomon-Reed algorithm for data distribution. This data distribution scheme ensures that even if 20 of those hosts go offline (whichever 20) the remaining 10 are enough to reconstruct the whole file and allow you to download the file.

Besides, hosts are heavily de-incentivized to drop or lose your files, as they lock Siacoins in the collateral that they lose if they don't keep your files with an uptime of 97% at least.


The revamped new official explorer allows you to search by addresses: http://explore.sia.tech

I recommend you this:

- My hosted data (the folders of renter's data) is in RAID arrays. So if one disk crashes, the data is never lost and I have time to replace it. Better RAID-5 or RAIDZ

- The installation of Sia and the metadata folders (those folders that in Windows are in %appdata%) backed up twice per day to an external disk (in my case the same RAID array of hosted data). This is less than 10GB. So if Sia, the host metadata or the OS crash, I can recover my SIa host from the backup.

Your issue is now resolved, so I think you should immediately edit your opening post with a huge bold opening text like "EDIT: the issue is now solved" or otherwise you are contributing to spread FUD, confusion and panic unnecessarily.

Just take a look at the posts before you posted it is now solved: most users do not read the whole thread and they are leaving it with the idea that this exchange is scamming innocent users

1 - If Sia is open, close it completely by right-clicking the system try icon of Sia > "close"

2 - Download the latest version of the software (v1.3.1) that was released two days ago if you are still on version 1.3.0

3 - Delete the blockchain database (consensus.db file) to allow the client to sync it freshly again. This file is located in the following path: Users\<user>\appdata\roaming\Sia-UI\sia\consensus\consensus.db

It is going to take several days (about 3 if it is continuously working) if you are using a HDD disk (mechanical), It takes less than 10 hours however if you are using a SSD disk. There is a trick for accelerating the initial sync: bootstrapping: https://siawiki.tech/daemon/bootstrapping_the_blockchain


If the transaction is not shown in the Explorer, is because it was never really pushed to the network. Open a support ticket in Poloniex. The developing team is also working with some exchanges to try to help them solve their issues.

Looks like a database of your host folder get corrupted. Are you hosting storage in Sia? If not, you can safely delete the host folder to allow Sia to reconstruct that database. First close Sia, then delete the "host" folder:

- On Windows is located at C:/users/your_user/appdata/roaming/Sia-UI/sia
- On MacOS: $HOME/Library/Application Support/Sia-UI/sia/consensus 

Download in your computer the official client (the Android app is not official) at https://sia.tech/apps/, wait until it is fully sync and use your recovery seed to access your funds

Version 1.3.1 just released!

Announcement post in Reddit: https://www.reddit.com/r/siacoin/comments/7l41hp/announcing_sia_v131/

Download: https://sia.tech/apps/

Instructions for updating, in case you are not familiar with the process: https://siawiki.tech/client/updating_the_interface

Take in mind this version is including a hardfork for correcting the Difficulty Adjustment Algorithm at block 139.000 (in about 5 weeks), so update your clients before that deadline!

Note: Like the last harfork, this is a non-contentious fork (all the community is accepting it and upgrading), so there will not be a new coin generated. In other words: this is not an "airdrop".

It is an issue some users are experiencing after the hardfork of 2 weeks ago. It should be totally fixed on the version 1.3.1 that is about to be released.

In the meantime, if your wallet is stuck in synchronization try this workaround to add more peers manually: https://siastats.info/nodes.html

SiaStats has a table with the average settings of the top 100 hosts of the network: https://siastats.info/hosts_network.html . When a renter makes file contracts, the client picks up those with a high score, so these top 100 are who get most of them. Currently they ask for 71SC/TB/month in storage and on average 20SC/Tb in bandwidth.

Currently there is much more storage offered by hosts than what is being used (a 3%) so currently it is not being profitable, unless you already have some empty TB sitting in a computer connected 24/7. However, once the usage increases it could be an interesting business: making about $1-2/TB/month you can ROI your disks in 18-24 months, and if you purchase NAS or datacenter-grade disks they will last 5 years or more. Electricity costs in hosting are irrelevant compared with mining (a 4-5 disks NAS box consumes less than 50W).

Happy Holidays too!

Go to the UI Terminal and type this command: "wallet init --force". That will destroy your current wallet and create a new one, providing you a recovery seed. Alternatively you can just delete the old wallet folder. In Windows is located on c:/users?you_user/appdata/roaming/Sia-UI/sia/wallet On MacOS on $HOME/Library/Application Support/Sia-UI/sia/wallet



I would love to know where those websites get their info from (pro tip: the fabricate it). We are very close to that version release, but  the developing never announces it for a specific date, they just release it as soon as it is ready. It can happen today, tomorrow or in one week, but that version is almost ready. Beta-testers have been testing the RC4 version these last days successfully

No devs of Sia are active on Bitcointalk as this is not an official channel. To directly communicate with them use the Discord or also the Reddit.

As far as I know, devs are aware of issues with some exchanges and they are working with them, specially with Bittrex


LOL, I just answered you in Reddit  I'll just add three details:

- Yes, if you have a total data loss, you'll lose the risked collateral

- While you can use backup tools to back your hosted data, I think RAID redundancy is enough for the task, and using an external disk to backup a RAID-1 array is probably a waste of resources (3 HDDs to keep the data equivalent to 1 disk is just too paranoid). Instead I would use other redundancy schemes as I told you in Reddit: RAID-5/6 or RAID-Z/Z2

- What I definitely recommend you to buck up daily (or even twice per day) is your Sia installatation and the external folders of Sia (in Windows located in %appdata%). Those are just a few GBs and if Sia gets corrupted and you don't have backups, you'll lose the whole hosting operation because the host database get corrupted. As I run Wndows Server, the native tool is enough for me.

No, I am not related to Nebulous, the company of Sia developers. I am a moderator of the official Discord and an independent developer (the author and owner of https://siastats.info). And of course an enthusiast of Sia too 

Sure thing: another relevant contributor of Sia made this awesome guide about how to start mining Sia in Windows: https://mtlynch.io/windows-sia-mining/


Take in mind Siacoin never had an ICO, it is a coin mined by PoW. The developers only pre-mined the first 100 blocks (less than one day of pre-mining). So it is coin that was fairly launched, like every good coin should be...

As the network is decentralized and pseudo-anonymous, it is impossible to know the precise amount of unique users.

However we know that the network has 66000 active file contracts: https://www.siastats.info/active_contracts.html If we assume that each renter makes 50 contracts with different hosts (default configuration), that means 1320 renters. If 1 user = 1 renter, then we can say there are approximately 1300 Sia users.

We have a better idea of the usage in terms of used storage in the network. SiaStats.info reports almost 99TB of used storage of a total of 3200TB available (https://www.siastats.info/hosts_network.html) and SiaHub.info reports 103TB of used storage of a total of 3300TB available (https://siahub.info/network)

Check the transaction ID ("hash" or "TxID") in https://explorer.siahub.info/ on the "hash" search box.

- If it doesn't show any result, the transaction does not exist on the blockchain. Open a support ticket on the exchange.

- If it exists, check that your Client is fully sync. If it says it is sync but in a block height under 137200, or you are having problems syncing, follow the instructions at: http://siastats.info/nodes.html

NP! Yes, you are required an uptime of 97%. Even if you have 2-3 days of downtime every 3 months, you are still good.

I am concerned that as you have not updated your client since last week when the hardfork took place, you might have lost some storage proofs, and so some contracts might be failing... Nevertheless the reputation of your host as observed by the renters should be good as even if your host was outdated and forked out, your data was available.

But try to restart your host as soon as possible: delete the consensus and sync your client again. If you are using a HDD for the installation instead of an SSD, consider bootstrapping to save time: https://siawiki.tech/daemon/bootstrapping_the_blockchain

And if you find problems not being able to sync the last blocks, try this fix: http://siastats.info/nodes.html

That error is one of the described in that link. Close Sia completely (in Windows, clock close on "Close" on the system try icon), delete the consensus folder, open Sia again and let the client to sync the blockchain again.

By this way you are just deleting the blockchain. Your recovery seed will be always good to recover your funds. In this or in any other computer
