3DPass: The Ledger of Things L1| New Proof of Scan algo

[3DPass]

Enjoy watching our new use-case video describing some opportunities of 3DPass being used for tokenizaton of items for Gaming, Virtual Reality, Metaverse. As a bonus, we'll share how to utilize Proof of Scan for running your own chains of limited supply assets.

When the testnet starts? What should I do to prepare?

I believe, we'll release the NODE containing Proof of Scan consensus implemented in 7-10 days. Then we'll publish some guide lines.

Hey, guys! Yesterday we gathered with our development team and decided that we need a couple of weeks more to the testnet launch. We are not ready yet, but we will put our efforts to start by April 15

There are some issues unaccomplished with consensus Proof of Scan yet, because we tried to modify BABE production mechanism first. However, we had to replace it with Aura one. BABE causes a lot of forks, even if the network feels well. So it took us some extra time to test it out.

Enjoy some 3DPass features before the network starts!

You can use real world 3D objects as cryptocurrency wallets, passwords or keys:
https://youtu.be/YAl2R_DefQE

1. Use your smartphone camera or any pro scanner to take  several 3D models of the same object. E.x. https://www.qlone.pro/ might be used for experiments

2. Export your 3D scans in .obj format

3. Use pass3d recognition tool for Linux or Android app to create a HASH ID out of your .obj scans. You should select the most sustainable hash which definitely comes up in each top10 processing result. You have to use the same set of parameters each time. It's recommended to set up the grid parameter (-g) value according to the lowest scan definition we expect to process in the future. Such values as -g=6 or -g=7 (6x6 and 7x7 grid) would be recommended for smartphones and tablets.

- Android app https://github.com/3Dpass/threedpass/releases
- pass3d user guide lines: https://3dpass.org/pass3d.html

4. Apply your HASH ID as a seed for any cryptocurrency wallet to recover.

How is the implementation of the testnet going?

[3DPass]

Hello everyone!

Welcome to test mining loop!
We are pleased to demonstrate Proof of Scan mining loop running on two nodes, which represent basically a minimal local network. It took us longer than we had expected, but we managed. And we are finally getting round to launching testnet. After a few tests we will set up Rewards and Genesis and then will start the network.

Follow the guidelines down the link to run Nodes and mining using Docker: https://3dpass.org/testnet.html

--
Node version: https://github.com/3Dpass/3DP/tree/dev_recipes
Miner: https://github.com/3Dpass/miner
--
The process:

Our simple CPU miner generates random-shaped 3D models in .obj format and sends them to the input of Proof of Scan consensus via RPC request to the NODE like this:

Code:

{
    "jsonrpc":"2.0",
    "id":1",
    "method":"push_mining_object",
    "params": [
        1,
        "o\n
v 0.05508197844028473 0.7671535015106201 -0.14178061485290527\n
v 0.05349433422088623 0.764365017414093 -0.10946107655763626\n
v 0.04743874818086624 0.7608485817909241 -0.07884219288825989\n
.....
            ]
}

Each 3D model is going to be processed by pass3d recognition tool producing its HASH ID. Once the correct 3D object is found, a new block will be proposed by the miner's NODE. The second Node imports the block, verifies it and checks if there is no the same-shaped objects in previous blocks. This check is guaranteed to avoid the network from copy-cats being proposed for a new block.

Are there any plans to release something on iOS?

Our mobile app (https://github.com/3Dpass/threedpass) is based on Flutter which supports iOS. After we implement wallet functions into it, we'll definitely release iOS app as well as Android. We're thinking of it as a mobile wallet providing some options of tokenization of things and its recognition, issuing tokens backed by them, etc.

What is the rate of sending 3D models to the PoScan consensus?

Miner is not confined for speed, it sends 3D models as fast as it gets ones generated. However, there is a limitation on the Node side. If the Node's queue is getting overwhelmed, it would respond with error for some time.

The miner has found a 3D object which is very similar to one already existing on the blockchain. So, it's been rejected.
We have set up recognition precision to be quite rough now. It's easier for us to test.

Welcome to test some mining rewards! 
Mining rewards trait has been implemented into Proof of Scan. So, you can check it out in local:

1. Build the Node: https://github.com/3Dpass/3DP (you have to have Rust set up properly https://github.com/3Dpass/3DP/blob/main/docs/rust-setup.md)
2. Import Alice's mining key into the local keystore:

Code:

target/release/poscan-consensus import-mining-key //Alice --base-path /tmp/alice

Alice's account is hardcoded for testing
3. Run the first node with the following:

Code:

target/release/poscan-consensus --base-path /tmp/alice --chain local --alice --port 30333 --ws-port 9944 --rpc-port 9933 --unsafe-rpc-external --node-key 0000000000000000000000000000000000000000000000000000000000000001 --validator -lposcan=debug --author 0xd43593c715fdd31c61141abd04a99fd6822c8558854ccde39a5684e7a56da27d

4. Run the second node:

Code:

target/release/poscan-consensus --base-path /tmp/bob --chain local --bob --port 30334 --ws-port 9945 --rpc-port 9934  --bootnodes /ip4/127.0.0.1/tcp/30333/p2p/12D3KooWEyoppNCUx8Yx66oV9fJnriXwCcXwDDUA2kj6vnc6iDEp --validator

5. Run the miner: https://github.com/3Dpass/miner
6. Connect to https://polkadot.js.org/apps/#/explorer or use the front-end template https://github.com/substrate-developer-hub/substrate-front-end-template to view the network stats.
Alice will receive some coins for each new block mined. 

Feel free to ask any question over Discord: https://discord.gg/u24WkXcwug

Hi,

Very interesting idea in 3D object I saw on discord channel that testnet is very good, but I saw also you have some issue on substrate regarding syncing chain???
Are you close to resolve issue?

Namely one word question how in real life ordinary people can have benefit using this 3D object processing???

btw awesome work just keep it up...

Testnet is online, I had no issue with syncing used bootstrap which is available at discord, as all substrate it require some nice server to keep it with sync

devs still work on optimizing the 3d model and sync which I guess will see more easy way to sync in future

That's great news I will explore discord and setup one to support great idea...

Syncing ....

I noticed, it takes power to validate the block imported. Is there any reward for that?

We've made a few improvements, which might help to solve some issues with syncing. The experimental version of the Node is available here: https://github.com/3Dpass/3DP/tree/dev2 However, there is an alternative way to catch up with the network fist is to download the actual blockchain db.

Hardware requirements have been added in the tutorial: https://3dpass.org/testnet.html#how_to_join_as_a_miner

Validation rewards are going to be implemented in a month.
