ProximaX Sirius has a multidimensional inner economy, where XPX is used to pay for services and power the blockchain. Internal non-tradable service units (storage unit, streaming unit, Supercontract unit, content review unit) are used to power communication protocols between the different node actors. This approach facilitates the future expansion of the platform by making it possible to add on new types of services.

ProximaX Delegated Validation System


Validators are rewarded for securing the network by running nodes


Rewards are dependent on wealth and age (Proof of Stake) and fee requested (Proof of Greed)


Regular users can delegate XPX directly from their wallets to Validators


These users enjoy their share of rewards without giving up control of their XPX

What networks are involved in the swapping process?

There are 2 networks involved, namely ProximaX Sirius which is the ProximaX main network and the NEM NIS1 network.

When can I swap my XPX tokens over to the Sirius Chain?

You will be able to swap your XPX tokens once the mainnet is live and the Sirius wallet swap function is available.

What do I need to do to effect the swap from NIS1 to ProximaX Sirius?

You will need to download the Sirius wallet and follow the instructions here.

What is the first step I should take to do the swap?

Save your current NIS1 private keys i.e. the keys to your current wallet that holds your XPX tokens. Funds can be lost if you fail to do so.

What are the steps I need to follow to swap my tokens?

1. Save and store your NIS1 private keys before starting the swap process.

2. Download the Sirius wallet.

3. Create a Sirius account wallet by importing your NIS1 account private key.

4. Select “SWAP” to begin the swap process and enter the quantity of XPX to be exchanged.

5. Once the transaction is confirmed and executed, your balance will be shown in the ProximaX Sirius wallet.

How do I conduct a swap for a multisig account?

Any co-signatory to a multisig account can initiate a swap. The basic steps are:

1. One of the co-signatories of the multisig account downloads the Sirius mobile wallet.

2. He creates a Sirius account wallet by importing his NIS1 account private key.

3. He selects “SWAP” to begin the swap process and enters the quantity of XPX.

4. He then selects to create a multisig transaction.

5. The system validates the multisig transactions and it is sent to the NIS1 network to be signed by the other co-signatories of the multisig account. The co-signatories must sign-off within 24 hours.

6. Once the transaction is confirmed, the swap takes place and the XPX balance is shown in the Sirius account.

How long will it take before my XPX tokens are reflected in my Sirius wallet?

It can take anything from a few minutes to several hours for the swap to take place.

What wallets will ProximaX be releasing?

ProximaX will be launching the Sirius wallet, which will come in a desktop, web, and mobile version.

Can I swap my tokens through my ProximaX mobile wallet V2 or NEM Nano wallet?

While this is possible, we will not be supporting this method as it is tedious. Hence, we strongly encourage all token holders to download the Sirius wallet and perform the swap there.

What are the pre-requisites to conducting a swap?

Yes, you will need your NIS1 private key and you will need some XEM (nem:xem) tokens to pay for the transaction. The amount required to pay for the transaction should be less than 1 XEM.

Do I need to pay for transaction fees on ProximaX Sirius chain?

Yes, but the native token for transaction fees will be the XPX. XEMs will no longer be required.

When should I swap my XPX tokens over from NIS1 to the Sirius Chain?

We encourage all XPX holders to do the swap as soon as possible.

How long will my XPX tokens stay on the NIS1 blockchain?

Your XPX tokens will exist until the year 2025 or when NIS1 is deprecated, whichever is sooner.

When will NIS1 migrate to NIS2?

We are not involved in migration and do not know the schedule. We will endeavour to port across from NIS1 to NIS2, however we do not know nor have any control over that migration path.

Can I lose my funds?

Yes, if you don’t save your private key in a safe place (hardware wallet, piece of paper, engraved in metal, etc). We are not responsible for the loss of any account. Save Your Private Keys!

Why is the first block (block 1/genesis block) created in 2016?

The development of Catapult started at around this time. We have decided to maintain the epoch time set by the core developers in the original code. This is to reflect the development time taken until the creation of the first mainnet launch using the Catapult technology. The second block is the official start time of the Sirius mainnet.

Finally, we would like to pay tribute to the core developers for their contribution to the technology: Jaguar0625, Bloody Rookie and Gimre.

For the tech savvy: constexpr auto Epoch_Time = std::chrono::duration<int64_t, std::milli>(1459468800000);

Will it be possible to run ProximaX nodes on a NAS

Technically, yes or if NAS supports Docker and if the hardware requirements are met, then yes it can be done as well. Sufficient bandwidth is also an important criterion.

Will ProximaX be compatible with Docker or will there be a Docker image available

There will be a docker image available for each type of peer-to-peer Storage Node.

What is the minimum hardware specifications and download/upload speed needed to run a node? What about the minimum disk space to share

A good amount of storage and a high bandwidth are prerequisites although the actual quantum is yet to be qualified in detail. However, a decent and adequate streaming speed for a node should be 20/20 Mbps.

In terms of disk space, there is no absolute minimum but the sharing of 1MB is not logical as it will inherit (almost) no rewards.

Is there a minimum XPX needed to run a node

There is no cost to run it other than the cost to run it as a node in the cloud. As R&D progresses, certain security sensitive services such as directory and node discovery services in ProximaX are expected to require minimum vested amount of XPX to eliminate certain kinds of attacks.

Is there any Super Node programme like NEM

It is likely that a similar structure will also be established although the details are still on the drawing board. It will be announced officially on all ProximaX’s communication channels when the time comes.

What is funding of the initial 200 nodes about

It is used to finance the initial 200 nodes while development of the reward and PoX consensus scheme continues. It is expected to run as a “free” solution for users to test, develop and even go into production while the ProximaX team work on the main releases.

Is the side chain a separate product or will it be integrated into the code of the node software of ProximaX

The side chain is part of the NEM Catapult protocol.

Is it possible to run NEM (NIS) and ProximaX on the same node

Yes, this is possible but hardware requirements would be higher in this situation.
