The Sia network is hardforking to reject all ASICs on the network except for Obelisk miners. This article will detail what you need to do, however you fit into the Sia ecosystem.
This guide is strictly practical. If you'd like to learn more about the decisions behind the fork, check the following links.
Sia v1.3.6 has been released! Download it here.
Hardfork is implemented
The fork will be implemented on October 31st at a block height of 179,000. Be updated by this date.
If you hold Siacoin...
...that's stored in our official wallet
We always recommend keeping Siacoin in Sia-UI, our official wallet, where you control the private keys. When the hardfork hits on October 31st, your updated 1.3.6 version of Sia will instantly give you access to the new chain, and all of your Siacoin will be available to you.
If some individual or group decides to maintain the non-fork chain, you'll also have coins accessible there as well.
...that's stored on an exchange
When an exchange updates their wallet, you'll now have the same amount of coins on the new Sia chain. These coins are usable:
- to trade with exchanges that also use the new chain. We expect all of them will.
- to buy storage from hosts who also use the new chain. We expect this to be the majority of hosts.
But what you don't have is access to the Siacoins on the old chain, unless the exchange you deal with decides to support the old chain or give you access to them.
If you store your files on Sia
Just be sure to upgrade to v1.3.6 by the 31st. Doing so ensures that you will continue to upload data to hosts also on the new fork.
You do have a little bit of flexibility here – as the repair mechanisms built into Sia will keep your data healthy – so being a couple of days late won't cause you significant stress.
If you host data on Sia
Hosts should absolutely upgrade their version of Sia to 1.3.6 before October 31st. If you fail to upgrade by the hardfork, all the renters who upgrade will stop forming contracts with you.
If you mine Siacoin...
...with an Obelisk miner
You'll need to update your firmware. Obelisk will release a firmware update that complies with the new mining algorithm introduced in Sia v1.3.6.
...with any other ASIC
Other ASIC mining hardware will still be effective on dissenting forks. GPU miners will be able to mine on the post-fork chain once their software is updated with the alterations to the proof-of-work algorithm.
If you're an exchange that trades Siacoin
Simply update to v1.3.6 of the software prior to October 31st. Once you do, your exchange will be able to support the fork once it takes effect.
