How can I run my own network?

[theahmadzadeh]

I wanna run my own blockchain network with waves node application for our companies internal use. I have studied the documentation provided in here and here. But I'm still facing a bit of problem; I am confused about what network configuration i should use in (e.g wavesplus-devnet.conf) for ports and bind address in network, matcher and rest api. also I don't know what to change in application.conf file in main/resources. Consider that I want to reduce key-block-interval to 10s and microblock-interval to 1s. I have noticed I should use genesis.it.conf and create a genesis block then put the output in conf file and run the devnet.conf file. How can other employees become a node in this network? afterwards how to use api to develope the rewarding app on this blockchain? will it be accessible through node's public ip address?

Sorry to ask so many questions! It's just so long since I'm trying to do this and I'm running out of time :|

[theahmadzadeh]

And what is api-key-hash in wavesplus-devnet.conf?

[vv12131415]

api-key-hash is the hash that you can get from here https://docs.wavesplatform.com/en/development-and-api/waves-node-rest-api/utils.html#section-56df3285daad4ea8cfeadbedffca4252

May be you can use this repo to run a private blockchain? I think it is as easiest way to run private chain https://github.com/wavesplatform/dev-toolkit

Hi, so.. many issues.. I will try to answer each item and ask you some questions. What is your OS? Have you installed these items? (Git [to clone the repository ], Java 8 [to run the application] and sbt [to generate a genesis]) In order to be able to help you, I need to know where you are wrong. And for that, I need you to show me the procedures you are executing.

First of all, you need to write a valid configuration file, according to its guidelines (10s for key-block-interval and 1s for microblock-interval)

I was able to create my own network after a long time of work (the documentation did not help me) and I can help you get where you need it. Answer my questions and I'll help you as soon as I can.

[theahmadzadeh]

Thank you all guys!
One more thing left is that our nodes don't work independently! What I mean is when I run a node on an other server it only keeps downloading(appending) blocks generated by our known-peers! What shall i do about it??

[theahmadzadeh]

Update: according to logs block mining doesn't happen because: "Not scheduling block mining because Balance 0 of 3FUW5wm3GDiMKB1n6ytaG8ZyPCpPPkuPhY4 is lower than required for generation" but in the swagger api I can see there is 70K coins in this address with 0 confirmations!

[alexeykiselev]

Please, check the /addresses/balance/details/{your-address} API, pay attention to effective or generating values of the response. There is a rule that the money moved to an account can be used for generation only after 1000 blocks passed since the transaction. So, I think, that you have to start the generation with one of the genesis accounts. And only after 1k of blocks you can start generate with the accounts you moved money to.

[theahmadzadeh]

Thanks @alexeykiselev Solved the main issue; but why the confirmations are still 0 ? I have 2 nodes so shouldn't it normally get at least 1 confirmation.

[theahmadzadeh]

[update] Here are the logs: [miner-pool-41] c.n.mining.MinerImpl - Adding 0 unconfirmed transaction(s) to new block

Could not append Block(38TskdrVRJ2vmTV1VmRD8zUT43aCxsmZa5ipSjB7hPParzs8SMiZMv1Kx3Kzwb1xaWsQfVqL8khMSUJ8SFNJaTek -> 5Ebfv6M..., txs=0, features=Set()): BlockAppendError(Block is not a child of the last block,Block(38TskdrVRJ2vmTV1VmRD8zUT43aCxsmZa5ipSjB7hPParzs8SMiZMv1Kx3Kzwb1xaWsQfVqL8khMSUJ8SFNJaTek -> 5Ebfv6M..., txs=0, features=Set()))

c.n.s.BlockchainUpdaterImpl - MicroBlock(4Neh3ee... -> 4vmTRpr..., txs=4) appended

[theahmadzadeh]

Is There possible for nodes to not be synced exactly?! My first node is on height 21432 While the second one is on 21435!

[alexeykiselev]

This is ok, the short forks are possible. The node that mined a block broadcasts it to all peers, so in the log you see the attempt to append that block to the fork that node builds at the time. The possibility of such forks a higher in case of equal balances on the mining nodes.

[theahmadzadeh]

It suddenly started over this morning!! Current height: 7543 How is this possible?? The transactions are gone for good!!

[theahmadzadeh]

My Transactions keep skipping from a block to another!

When I check for a transaction info by id it's height changes to most recent block on every refresh! What's the problem?

[Karasiq]

You block intervals are too short, nodes don't have enough time to sync https://github.com/wavesplatform/Waves/issues/1911

Hello! Can you help me to create my private network? I don`t sure that my configuration file is correct, Can you share the valid configuration file for example? Thanks!

You need generate a genesis block before..

[Vlad71]

Thank you! But I caught the next problem and don`t know what do I need to tune in the config file. There is the problem: "Could not append Block(3AQJgjF98Yk6orktnb9qzEfqFX3UeyTAxfiU9saZXA2zNJs8UAcij5RV2y2SPUH6cFGPSyHwXpwawNSWMCbkLCPd -> 3ExffMY..., txs=0, features=Set()): BlockAppendError(Block is not a child of the last block,Block(3AQJgjF98Yk6orktnb9qzEfqFX3UeyTAxfiU9saZXA2zNJs8UAcij5RV2y2SPUH6cFGPSyHwXpwawNSWMCbkLCPd -> 3ExffMY..., txs=0, features=Set()))"

P.S. I am creating private network of Vostok platform, I think the one is closely similar to the Waves platform.
