Hi guys. For my first steps with RSK, I need my address whitelisted on testnet

Alejandro Cavallero

@alepc253

@sfurman89 you don't need to go through the bridge, you just can use https://faucet.testnet.rsk.co

and get tRBTC from there

Simon

@sfurman89

great, thank you

Hello guys,
I am trying to run rskj-core from command line on an arm32 device. Following the guide at https://github.com/rsksmart/rskj/wiki/RSK-node-from-command-line, I could get gradle to compile rskj, but when I try to run the node with:

java -cp $(ls /home/rsk/rsk/rskj/rskj-core/build/libs/*-all.jar) co.rsk.Start

i get the following error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: Could not load library. Reasons: [no leveldbjni in java.library.path, /tmp/libleveldbjni-32-1717003347813397553.so: /tmp/libleveldbjni-32-1717003347813397553.so: cannot open shared object file: No such file or directory (Possible cause: can't load IA 32-bit .so on a ARM-bit platform)]
 at org.fusesource.hawtjni.runtime.Library.doLoad(Library.java:182)

I couldn't find a way to obtain and compile libleveldbjni-32 on arm32. Did someone find a solution to this?

@alepc253

@pollodigomma arm32 device is not yet supported

we'll come back to you when we have news about it

The BTC/rBTC conversion whitelist Google Form looks like I'm registering a product or smart contract. I'm not a company. Just have a MyCrypto wallet and some rBTC to play with. Do I still need to fill out this whitelist form?

Alejandro Cavallero

@alepc253

Hi @geoburke_twitter, if you need test RBTC, you don't need to whitelist and use the bridge, you can just go to https://faucet.testnet.rsk.co

if you need mainnet RBTC and you don't want to use the bridge, you can buy them in an exchange > https://coinmarketcap.com/currencies/rsk-smart-bitcoin/markets/

@leonelcorso_gitlab @sebaleoperez Hi there, we are having the same problem, any solutions? we are behind a NAT not able to connect to any peers. Tried adding the peer list above, with no results. We are on Testnet. Any help? thanks

horca17

@horca17

done, it is working now.

@zichenglang

@alepc253 Hello, I have a question

How can my bitcoin address receive the money when I'm making payments to bridge address on the RSK network?

Rsk network doesn't even know what my btc address is

Alejandro Cavallero

@alepc253

@zichenglang your RSK address is derived from your BTC address, that's how the bridge knows

details of that conversion: https://github.com/rsksmart/rskj/wiki/Peg-using-node-and-console#from-rbtc-to-btc

Leonel Corso

@leonelcorso_gitlab

@horca17 Ok, great to know it's working

horca17

@horca17

@leonelcorso_gitlab well I was able to connect to the node, but I am not able to connect to peers, do yo have a testnet.conf that works?

Leonel Corso

@leonelcorso_gitlab

No, I haven't I was unable to run it behind NAT.

horca17

@horca17

rpc {
providers : {
web: {
cors: "*",
http: {
enabled: true,
bind_address = "0.0.0.0",
hosts = ["local ip", "public ip"]
port: 4444,
}
ws: {
enabled: false,
bind_address: "0.0.0.0",
port: 4445,
}
}
}

we were able to run behind NAT with this configuration

Leonel Corso

@leonelcorso_gitlab

But did it sync?

horca17

@horca17

nop, but was able to curl

Leonel Corso

@leonelcorso_gitlab

Right. Yes, had the same issue. I mapped the port and all but was unable to sync.

horca17

@horca17

any help from RSK?

Alejandro Cavallero

@alepc253

this is something that came up more than once... it's networking, not a node issue

but please post the context

horca17

@horca17

port mapped TCP/UDP 4444, 4445, 50505, 5050, any other that you may know?

Alejandro Cavallero

@alepc253

hmm no... the last two are the used for peer discovery (UDP)

horca17

@horca17

@alepc253 link to the issue?

Alejandro Cavallero

@alepc253

no link... just scroll up this room or rsksmart/rskj

do you see something strange here?

horca17

@horca17

is somebody behind NAT connecting with any peers, I am not able to sync.

horca17

@horca17

It is working now, it is syncing, we had to change testnet networkId from 779 to 8100, it was noticed on the net logs with verbosity ALL. Let me know if it works for you.

hi, i have a problem with conversion from rbtc to btc

Alejandro Cavallero

@alepc253

@zichenglang whitelisting done!

horca17

@horca17

OK, the node on Testnet that we started on our server at OVH y now running, has sync, and also we had migrated EIP20.sol using truffle, plus it is mining. Great.

Alejandro Cavallero

@alepc253

@horca17 nice to read that!

horca17

@horca17

We are now running our own node on OVH with RSK testnet and we are mining. Also, we have migrated using truffle a Token dApp, where you can buy fake tokens using RBTC @0,001. It uses Metamask, and in order to make it work you have to configure the Network on Settings, Network name: RSK Testnet, RPC URL: https://rsk.qubistry.co/1.1.0/ ChainId: 31, Symbol: RBTC, and depending of the version of Metamask, on Connections you have to manually add the site to allow it access to our account, rsk.qubistry.co. Then, on browser type http://rsk.qubistry.co:33000 and you will access to the front end, where you will be able to test a Smart Contract done on Solidity, deploy using Truffle on RSK, and interact with a front end buying dApp Tokens. You have to have RBTC on your account, you can receive 0,05RBTC from https://faucet.rsk.co/. Good luck.
