Crust “Profit Ark” Incentivized Testnet is Coming!

We are pleased to announce the launch of the Crust Network Incentivized Testnet “Profit Ark” node recruitment. The first phase of Crust Network’s incentivized testnet Maxwell will commence in mid-November, focusing on software and hardware testing of network nodes.

The first phase of “Profit Ark” will issue no less than 300,000 CRU or equivalent in rewards. Before the start of the incentivized testnet, we welcome everyone to participate in the currently running non-incentivized testnet as a node, so as to obtain a certain understanding of Crust Network in advance. To participate in the Maxwell CC2 network process, please refer to the Maxwell CC2 node manual (link).

Note:

• The storage capacity of the node during the current non-incentivized test period will not be included in the incentivized test phase, while the node needs to be reconfigured during the incentivized test phase.
• All times mentioned in this document refer to Beijing Time (UTC+8).

Testnet Hardware Configuration

Please refer to the Crust Node Hardware Specifications (link).

Test Purpose

The first stage is a software and hardware test, which mainly tests the performance of nodes in the network, network bandwidth, storage capacity and rewards distribution.

Test Time

Mid-November 2020 to Early December 2020

Rewards Rules

During testing, we will take the block generation rate, work report success rate and the total storage capacity into account in order to distribute rewards accordingly.

Testnet Node Form

You can choose either a single node, or a cluster of multiple nodes in the LAN to join the network. Since the block generation process and the storage workload reporting process have relatively high requirements for network stability, similar to the Kusama network or other projects of Polkadot ecology, we strongly recommend that the block generation node use a fixed public IP, otherwise it will bring forth losses due to unstable block generation. In addition, considering that the next stage of testing will focus on service capabilities, we recommend that you use a multi-node cluster form to join the network to prepare for the next stage of testing and the main network.

Single Node Form Configuration

In the single-node form, you should run chain module (Crust Chain) and storage module (sWorker) in the only node.

The single-node morphological topology diagram is as follows:

Node manual will be released later.

Multi-node Form (Recommended)

In the multi-node form, you need to run the chain module (Crust Chain) on the service node. At the same time, you can scale the storage module (sWorker) to multiple storage nodes, which means that your storage capacity can be horizontally expanded.

The multi-node morphological topology diagram is as follows:

The node manual will be released later. Users can fill in the “Crust Profit Ark Registration Form” (link) to participate. After submission, please join the Crust Network Telegram group and contact the admin.

Community Activity

To allow non-technical users to join in the “Profit Ark” activity, we have designed the following activities and will distribute a certain amount of Crust Candy to those who contribute to the community. Crust Candy will be used for voting in the Crust community. The conversion ratio between Crust Candy and CRU is 1000:1. The conversion method, time and other specific parameters of Crust Candy and CRU will be announced after the first phase of the incentivited testnet has been launched.

• Invite 5 friends
• Create Crust emojis
• Develop Crust testnet accessories
• Community Q&A
• Make Crust or testnet info cards
• Compose incentivited testnet related instructions

Appendix: What are the differences between Crust and Filecoin?

Both Crust and Filecoin are completely decentralized storage networks, which means that neither “super nodes” are introduced in the storage proof mechanism of nodes (some projects have introduced super nodes in the storage proof problem). Crust and Filecoin are also very different. The first is the difference in storage proof algorithms. A core problem in decentralized storage networks is that storage nodes need to prove to the chain which files they have stored correctly. Filecoin’s core proof mechanism, including Proof of Replication (PoRep) and Proof-of-Spacetime (PoST), is based on a large number of complex cryptographic calculations. Crust is implemented through local storage verification based on TEE. The second difference is in the chains. Filecoin developed its own chain. Crust’s chain is developed based on the Substrate framework, so that the consensus algorithm, on-chain and off-chain working machines, account system, upgrade mechanism, etc. are all consistent with the Polkadot ecology. Additionally, there is no reinvention of the wheel. Combining the previous two differences, Crust’s advantages are mainly reflected in: low cost, high maturity, and easy integration with Blockchain applications.

First: low cost. Due to the complex proof algorithm, the cost of Filecoin nodes lies in the high configuration of the mining machine and the need to consume a lot of computing power. Crust’s TEE-based technical solution is meant to be more economical, and tolerant of mining machine configuration requirements.

At the same time, nodes do not need to purchase coins in advance for “pre-staking” for mining on the Crust Network. Crust’s GPoS consensus protocol allows nodes to accept guarantees from currency holders to obtain staking, and the upper limit of staking depends on the storage service of the node. Therefore, the incentive of the Crust network to nodes is not to simply “heap computing power and heap storage”, but provide high-quality services, which promotes a virtuous circle of cooperation and engagement between coin holders and miners. The second advantage is high maturity, which refers to the maturity of the storage proof and the maturity of the chain. Filecoin’s proof algorithm is still iterating, and the corresponding mining machine hardware specifications may have relatively large changes. The TEE technology based on Crust is an industrial-level mature module. In the meantime, more powerful functions are being continuously developed in TEE’s ecological technology.

Crust’s chain is developed based on Substrate, which is also a very mature framework. Last but not least, easy integration with Blockchain applications. Here is an example to illustrate the differences of different landing modules. In order to resist various file generating attacks, Filecoin and Crust need to encrypt the files before they can be correctly stored. With Filecoin’s encapsulation algorithm, it takes nearly two hours to encapsulate a 32GB file, while Crust (based on TEE’s own re-encryption technology) only requires 2 seconds per 1GB.

In addition, Substrate-based on-chain governance and no fork upgrade mechanism make Crust able to smoothly upgrade the protocol without forking. This will be very friendly for future applications landing based on Crust Network.

The first phase of the Crust Network Incentivised Testnet will be coming soon, and everyone is welcome to join and promote the Crust Network into a new stage.

About Crust

Crust implements the incentive layer protocol for decentralized storage. It is adaptable to multiple storage layer protocols such as IPFS, and provides support for the application layer. Crust’s architecture also has the capability to support a decentralized computing layer and build a decentralized cloud ecosystem.

At present, public testnet Maxwell CC2 is live, and welcomes everyone to join for testing. Crust Network participated in both the Substrate Builders Program and Web3.0 Bootcamp, and also obtained a Web3 Foundation Grant.
