**Why Grin-Node Challenge 2020?** > To stabilize the GRIN-Network, we need to ensure we have enough running Grin-Nodes on the Mainnet-Network. We are believing in GRIN and the future of GRIN, therefore we setting up this challenge. **Who can participate?** > Everyone with a non-commercial Grin-Node. > All commercial nodes are allowed to connect as well but they wont win any prices. **How can you participate?** > It is simple, just run a Grin-Node over the measured time period from 22.03.2020 12:00:00 noon (UTC+0) to 22.04.2020 12:00:00 noon (UTC+0) and connect your Grin-Node to Grinnode.live **What can I win?** > [Full list here](https://github.com/MCM-Mike/grinnode.live/blob/master/free-grin-challenge.md#prices--free-giveaways) **Where can I find the Node-Challenge leader board?** > [https://grinnode.live/challenge](https://grinnode.live/challenge) **When does it start?** > 22.03.2020 12:00:00 noon (UTC+0). > _All previous statistics will be set to zero._ **When does it end?** > 22.04.2020 12:00:00 noon (UTC+0) **Where can I find more details?** > [https://grinnode.live/challenge](https://grinnode.live/challenge) **Issues / Problems?** > Please contact us. **Contact:** > [https://github.com/MCM-Mike/grinnode.live/blob/master/contact.md](https://github.com/MCM-Mike/grinnode.live/blob/master/contact.md) > Or on GRIN-Discord [Grin Community](https://discord.gg/X5bPyRg) Channel: #node-challenge **Thank’s to:** 🙂 👍 (1) @WarmBeer for the new Grinnode.live Website (2 ) Ro (Tian Qi) [https://grin.fan/product/grinshirt/](https://grin.fan/product/grinshirt/) who are sponsoring T-Shirts in corporation with Grinnode.live _[https://grinnode.live/](https://grinnode.live/) is NOT optimized for mobile devices, if someone can help, contact me._ ---

Very cool! > To stabilize the GRIN-Network, we need to ensure we have enough running Grin-Nodes on the Mainnet-Network. While it’s important for everyone receiving Grin to run a full node, running a full node just for the sake of it only adds value _if_ the nodes are accepting incoming connections. To ensure this happens, everyone should setup port forwarding on port 3414, and confirm that grin-server.toml is configured to accept incoming connections. ---

For those feeling a bit lost, you just need to add this IP to your config file in order to connect to the challenge node and be counted: ```auto peers_preferred = ["213.239.215.236:3414"] ``` Source: [https://grinnode.live/](https://grinnode.live/) ---
**Author:** ![Chronos](https://yyz2.discourse-cdn.com/flex036/user_avatar/forum.grin.mw/chronos/32/153_2.png) [@Chronos](https://forum.grin.mw/u/Chronos)\ **Post date:** [March 23, 2020, 3:37am UTC](https://forum.grin.mw/t/grin-node-challenge-2020-win-over-800-grin-coins-and-free-grin-merchandise/7166/8 "2020-03-23T03:37:32Z")
Actually, my node isn’t being counted, and that IP doesn’t appear under “Peers and Sync” in the menu. Here’s my .toml: ```auto peers_preferred = ["213.239.215.236:3414"] #maximum number of inbound peer connections peer_max_inbound_count = 30 #maximum number of outbound peer connections peer_max_outbound_count = 10 #preferred minimum number of outbound peers peer_min_preferred_outbound_count = 10 #temporarily allowed to exceed peer_max_inbound_count peer_listener_buffer_count = 5 ``` I can ping that IP and can telnet into 3414 from my node. When I switch to “List” seeding, and explicitly set that IP, I have 0 connections at first, and then eventually pick up a connection which doesn’t match that IP. Otherwise, I quickly get 10 outbound connections that don’t match that IP. What could be the problem? ---

> [@Chronos](#): > > What could be the problem? You are doing everything correct. If you connect to the high-available IP address using `peers_preferred = ["213.239.215.236:3414"]` your node gets redirected to one of our GRIN-Nodes. As long as you see connections to any Grin-node with sub domain : ` *.grinnode.live:3414` you are fine and your node is being added to the challenge. ---

I asume winners are selected at random or based on random chance corrected for the up time, right. Otherwise joining the list or setting up a new node right now would automatically not win… and I want T-Shirt 😢 ---

_You are correct, joining now will not bring you in Top20._ # **But, let’s do the following and adjust the current rules a bit:** If more than 20 Users reply here telling us, we have successfully setup a Grin-Node and connected to Grinnode.live, we will add 10 more T-Shirts 👕 to the winning pool. - Winners will be randomly chosen from all connected nodes during the 4 week Challenge - Top20 Nodes can not win any additional T-Shirts - only non-commercial Grin-Nodes can win any prices. **What do you think about this?** 👍 👎 Leave a ❤ and share this Post ---

@david, I do not see a grin-server.toml file as part of Grin++. What config file does Grin++ use where I can specify the peers\_preferred? Thx. ---

I just realized I cannot setup additional nodes due to the need for port forwarding for port 3414 😅. Since I forward the ports used by Grin to one computer cannot redirect to another, right? I was even thinking of going for three nodes by adding a node running on a Raspberry Pi. Any thoughts on how to circumvent this limitation? ---

Don’t stop using Grin++ to participate 🙂 But, if you are on Windows I can recomend you setting up a Grin-Node under Windows following my How-To: [https://github.com/MCM-Mike/grinnode.live/blob/master/documentation/node/winodws-how-to-run-node.md](https://github.com/MCM-Mike/grinnode.live/blob/master/documentation/node/winodws-how-to-run-node.md) to run a Grin-Node and connect to us. (not 100% ready but it will guide you through the steps) You can also share this link and I am writing on an official Windows Grin-Node article here on the main repository: [https://github.com/mimblewimble/docs/wiki/(draft)-How-to-run-a-Grin-Node-(Windows)](https://github.com/mimblewimble/docs/wiki/%28draft%29-How-to-run-a-Grin-Node-%28Windows%29) (also in draft state) As always have fun 😃 [Next page](https://forum.grin.mw/t/grin-node-challenge-2020-win-over-800-grin-coins-and-free-grin-merchandise/7166.md?page=2)
