Hi everyone, I am Louis from Daimler team
Can you provide me some guides to set up and configure private Parity Ethereum with OP?

adonnini

@adonnini

@kremalicious hi when will @ssallam be available again? I need his help in getting a quid-Java to support access to commons. Thanks

@kremalicious I meant squid-java. Sorry

Alex Coseru

@alexcos20

@khanhphungntu - check out barge (https://github.com/oceanprotocol/barge/). Without any options (./start_ocean.sh) will install a private POA network (spree) and then it will deploy the contracts (keeper-contracts). After the contracts are deployed, all other components will start (aquarius,brizo,commons, etc)

@pallares6

Hello!!. When i run barge with nile testnet i have two problems. One of these is that i just can link my metamask account in https://commons.nile.dev-ocean.com/ but not in http://localhost:3000.

The other one is that smart contracts don't run well in my deployment

If someone would help me, I'd be very grateful

Matthias Kretschmann

@kremalicious

@adonnini I suggest again to rather open issues in squid-java and repo, and describe your problem there. This would also greatly increase the chances of helping everyone who runs into same problems as you

Matthias Kretschmann

@kremalicious

@pallares6 when running under http://localhost:3000 to which network are you connected in MetaMask? You should choose Localhost:8545, and NOT Nile because the networks are all remote networks.

As for the red Contracts lamp, you can ignore that for now if the only warning message in browser console you see is Error on contract ComputeExecutionCondition. This is a known issue right now with Brizo loading v0.13.1 of keeper-contracts but squid-js already loads v0.13.2. This should not affect any existing live functionality, meaning publish & consume should still work

@pallares6

@kremalicious I'm connecting to localhost:8545 in metamask but with Nile net, I didn't know so. I will try with spree net, thank you!

@adonnini

@kremalicious I did as you suggested several weeks ago. I am still waiting for a response from @ssallam Thanks

@montanaflynn

Hi, I have some PROCN tokens, how can I exchange them for real ocean tokens?

Nevermind I guess they automatically got put in but I didn't see them.

@adonnini

@kremalicious @ssallam I just added a new entry to the squid-java issue related to the failure to access Commons

Hello.
I proposed OEP about Layer2(state channel) to solve scalability a week ago so I would appreciate if you could review.
Thanks.

@adonnini

@kremalicious @ssallam I noticed that keeper contract releases are no longer on maven.

When I go to
https://www.npmjs.com/package/@oceanprotocol/keeper-contracts/v/0.13.2#packages

it states:
"To facilitate the integration of the Ocean Protocol's keeper-contracts there are Python, JavaScript and Java packages ready to be integrated. "

and

" Java Maven package - The Maven keeper-contracts package provides the same ABI's to be used from Java.

The packages contains all the content from the doc/ and artifacts/ folders."

Where can I get the latest release of keeper contracts?

If the jave version of keeper contracts is no longer available, and effectively, yuou are no longer supporting Java, please let me know. I will find an alternative solution for my application.

I would appreciate a response to this post. I do not want to keep bothering you, and wasting your and my time.

Thanks

Alex Coseru

@alexcos20

@adonnini - unfortunately, we do not maintain the java package anymore, due to lack of resources.

you can find the latest keeper release here (https://github.com/oceanprotocol/keeper-contracts)

adonnini

@adonnini

@alexcos20 Thanks for getting back to me. It's too bad I really wanted my app to work with Ocean Protocol. I am not looking forward to looking elsewhere. However, unfortunately, I don't have much of a choice. Thanks.

Alex Coseru

@alexcos20

@adonnini - what are the req for your app? maybe you can leverage some calls to the agent

adonnini

@adonnini

@alexcos20 That would be great. Here are the blockchain related functions of my app, which I have already implemented on the bigchainDB testnet:
1) Store detailed location information for access points (AP) (primarily WiFi)
2) For each AP with a record stored on the blockchain, update that record as needed (using CRAB approach)
3) Retrieve record of APs in the vicinity (as given by one GPS reading) of a user's current location to accurately estimate that user's indoor/outdoor location
The above three functions have been implemented and work using the bigchainDB testnet. Until last summer, using squid-java I was on my way to completing implementation to store, update and retrieve AP location information on Nile testnet (I was in the final pahse of testing/debugging).
Since the changes to squid-java (version 0.8.0), my work has stopped because of issues with squid-java which @ssallam is aware of.
With functions 1), 2) and 3) running, the next phase would include storing of user location and user mobility analytics information the blockchain for resale to third parties.
I hope this answers your question.
Again, thanks for your offer to help,
Alex Donnini

@DickensJuma

@adonnini I have some ETH in Pacific Network how do i convert then to Ocean Tokens?

lexicond

@lexicond

Are others finding that they cannot currently consume files from commons? Error appears: 'undefined. Sorry about that, can you try again?'

lexicond

@lexicond

On this note, has anyone tried linking Mantaray to the commons network, I'm successfully searching the data assets but cannot consume them
Believe that it's the same issue

adonnini

@adonnini

@DickensJuma I stopped working on integration of my app with Ocean Protocol. I have not received response to any queries made to the Ocean Protocol team for more than three months

Manan Patel

@innoprenuer

@DickensJuma ETH in pacific network is only a gas utility (meaning it doesn't hold any monetory value as of now) and its provided free to perform transactions on Pacific network. So, you wont be able to convert it to OCEAN tokens (they have monetory value). I hope that answers your question.

@adonnini unfortunately, we are not officially supporting squid-java anymore so you might have to add new and custom features to it yourself if you need them. maybe you can find devs who might want to use java driver as well and then can contribute together on it.

Manan Patel

@innoprenuer

@lexicond there is no 'commons' network. You are either talking about 'nile' network (our testnet) or 'pacific' network (our mainnet). And you will be able to consume them with on both networks with correct config. For more details, check out - https://docs.oceanprotocol.com/tutorials/jupyter-notebooks/

adonnini

@adonnini

@innoprenuer , I already knew that. Please take a look at the exchange of messages I had with @alexcos20 . He kindly asked me
"what are the req for your app? maybe you can leverage some calls to the agent"
I answered his question:
"1) Store detailed location information for access points (AP) (primarily WiFi)
2) For each AP with a record stored on the blockchain, update that record as needed (using CRAB approach)

I am waiting for his or anyone's answer.

adonnini

@adonnini

@innoprenuer could you think you or someone else get back to me after reading my response to @alexcos20's question (see @alexcos20 03/05 post above)? I would love to be able to leverage calls to the agent as @alexcos20 suggested above. Thanks

Alex Coseru

@alexcos20

@adonnini - you have two ways of doing that

1 - use the agent to publish/consume ddo

2 - use squid-js to develop your own API backend which will accept calls from you app and under the hood you can use squid-js to publish/update ddo as you like (including adding custom fields in additionalInformation attribute in metadata service)

i would go with 2 without hesitation

take a look at https://github.com/oceanprotocol/react-tutorial and see how you can use squid-js (ignore react specific code)

writing an nodejs express backend that uses squid-js should be a two day job at most

adonnini

@adonnini

@alexcos20 Thanks. I will follow your suggestions

hi,I create an https site, I do not want to go through the stripe, what solution is possible to create a cosmos blockchain and create a payment bridge
is this possible or can i find a developer?

@rkashmirian_twitter

Hi, can anyone please explain to me what are the total costs for using Ocean Protocol. I am new to this and would like to understand all of the different nuances. I understand that the Ethereum network is also in play and hence there will be cost associated with Eth Gas. Thanks in advance.

@Rjrunner44

does ocean commons marketplace support Nile testnet? didn't see a way to connect that. Also, I uploaded a small (I hoped test) data file to commons, but I don't see any way to now remove/delete it. Didn't really want to leave it out on the main marketplace. Thx.

to my knowledge it's gas freee

@innoprenuer can we consider ocean protocol as a side chain of ethereum?

I have a similar query
