I am trying to run a local testnet with the instructions here. https://docs.tomochain.com/developers/tutoprivatenet/

I set up two nodes with the first one as the masternode. And start them with following commands.

./tomo  --syncmode "full" --datadir  local/1  --networkid 8080 --port 10303 --keystore keystore/1 --password password.txt --rpc --rpccorsdomain "*" --rpcaddr 0.0.0.0 --rpcport 1545 --rpcvhosts "*" --rpcapi "db,eth,net,web3,personal,debug" --gcmode "archive" --ws --wsaddr 0.0.0.0 --wsport 1546 --wsorigins "*" --unlock "acee47e431fdc623d6729f730942a8d71f67ecf1" --identity "NODE1" --mine --gasprice 2500 --bootnodes "enode://a5effe3cf84c2c1370c4930e2298498e80f1c4633a7a05cd4577533b219d668bff60b10ac6f9e4bdc424b123b1e40ea48f3a461308d5f265a9d5b01930d26732@127.0.0.1:30301" console


./tomo  --syncmode "full" --datadir local/2 --networkid 8080 --port 20303 --keystore keystore/2 --password password.txt --rpc --rpccorsdomain "*" --rpcaddr 0.0.0.0 --rpcport 2545 --rpcvhosts "*" --rpcapi "db,eth,net,web3,personal,debug" --gcmode "archive" --ws --wsaddr 0.0.0.0 --wsport 2546 --wsorigins "*" --unlock "374b313e956cdd34324fa2691870537ce354b81e" --identity "NODE2" --mine --gasprice 2500 --bootnodes "enode://a5effe3cf84c2c1370c4930e2298498e80f1c4633a7a05cd4577533b219d668bff60b10ac6f9e4bdc424b123b1e40ea48f3a461308d5f265a9d5b01930d26732@127.0.0.1:30301" console

Then the second one gives me this error and exit.

ERROR[12-31|21:33:15] Can't create new DB error="resource temporarily unavailable"
\

I don't know why because I used two different dir to store the chain data.

For further information, my node 2 crashed with this stack info

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0xc3cbc6]

@thanhson1085

Can you try with v1.5.6.

Run at least 3 nodes

qiushui

@qiushui777

Thanks for your reply. Yeah, my version is

 ./tomo version
Tomo
Version: 2.0.2-beta
Git Commit: 3f78f9ffef209ebb0fa21ffc307586fae48149e3
Architecture: amd64
Protocol Versions: [63 62]
Network Id: 88
Go Version: go1.13.3
Operating System: linux
GOPATH=/home/sam/go
GOROOT=/usr/local/go

And to make my problem more clear. I ran 3 nodes , and set 1 as master node with puppeth.

And I ran node1 (master node ) with commands like following

./tomo  --syncmode "full" --datadir  ~/work/blockchain/tomochain/build/bin/local/1  --networkid 88 --port 10303 --keystore keystore/1 --password password/password1.txt --rpc --rpccorsdomain "*" --rpcaddr 0.0.0.0 --rpcport 1545 --rpcvhosts "*" --rpcapi "db,eth,net,web3,personal,debug" --gcmode "archive" --ws --wsaddr 0.0.0.0 --wsport 1546 --wsorigins "*" --unlock "261ed497f94be3f43c2a820af706c4276618bbc5" --identity "NODE1" --mine --gasprice 2500 --bootnodes "enode://a5effe3cf84c2c1370c4930e2298498e80f1c4633a7a05cd4577533b219d668bff60b10ac6f9e4bdc424b123b1e40ea48f3a461308d5f265a9d5b01930d26732@127.0.0.1:30301" console

And then node1 gives me this console

INFO [12-31|22:43:31] Etherbase automatically configured       address=0x261eD497f94be3F43c2a820Af706C4276618bbc5

this one looks great

Then I ran node2 with commands

./tomo  --syncmode "full" --datadir ~/work/blockchain/tomochain/build/bin/local/2 --networkid 88 --port 20303 --keystore keystore/2 --password password/password2.txt --rpc --rpccorsdomain "*" --rpcaddr 0.0.0.0 --rpcport 2545 --rpcvhosts "*" --rpcapi "db,eth,net,web3,personal,debug" --gcmode "archive" --ws --wsaddr 0.0.0.0 --wsport 2546 --wsorigins "*" --unlock "152ae8aac5009276f2be8aa82bf66e67b4adf55c" --identity "NODE2" --mine --gasprice 2500 --bootnodes "enode://a5effe3cf84c2c1370c4930e2298498e80f1c4633a7a05cd4577533b219d668bff60b10ac6f9e4bdc424b123b1e40ea48f3a461308d5f265a9d5b01930d26732@127.0.0.1:30301" console

It gives me this error

ERROR[12-31|22:43:50] Can't create new DB                      error="resource temporarily unavailable"

And crashed with

@qiushui777

Then I also ran node3 with commands

./tomo  --syncmode "full" --datadir ~/work/blockchain/tomochain/build/bin/local/3 --networkid 88 --port 30303 --keystore keystore/3 --password password/password3.txt --rpc --rpccorsdomain "*" --rpcaddr 0.0.0.0 --rpcport 3545 --rpcvhosts "*" --rpcapi "db,eth,net,web3,personal,debug" --gcmode "archive" --ws --wsaddr 0.0.0.0 --wsport 3546 --wsorigins "*" --unlock "d152f8312dd678c50b8f3b0090cf924d743cc97e" --identity "NODE3" --mine --gasprice 2500 --bootnodes "enode://a5effe3cf84c2c1370c4930e2298498e80f1c4633a7a05cd4577533b219d668bff60b10ac6f9e4bdc424b123b1e40ea48f3a461308d5f265a9d5b01930d26732@127.0.0.1:30301" console

This one gives the same

Can't create new DB                      error="resource temporarily unavailable"

But it didn't crash just continue showing the messages

I actually followed your instructions but failed. Can figure out why. I really appreciate if you can help me with this problem.

I am going to try v1.5.6 and will came back if there is any problem

Nguyen Sy Thanh Son

@thanhson1085

No, you have to run at least 3 Masternodes, required by POSV consensus

qiushui

@qiushui777

Thanks. I tried v1.5.6. This time node2 and node3 is producing blocks. What do you mean by 3 masternodes? I specify the node1 to own the first masternode with puppeth. But for node2 and node3, how to specify them as masternode?

qiushui

@qiushui777

Ok, succeed with configuring 3 nodes to seal the block. So v1.5.6 is good.

qiushui

@qiushui777

@thanhson1085 Hi, v.1.5.6 doesn't contain the tomox directory which the master branch contains. So with v1.5.6 we are not able have those orders related features? There is no tutorial on setting a local DEX with the local private net.

https://github.com/tomochain/tomochain/tree/15fd865e55e2f40eac492c947bff6746f434f38f/tomox I mean this part of codes.

Nguyen Sy Thanh Son

@thanhson1085

not released that tutorial yet

But you can run DEX to join testnet

https://docs.tomochain.com/masternode/tomox-sdk/

qiushui

@qiushui777

Ok, cool. Looking forward to the tutorial.

qiushui

@qiushui777

BTW, currently, it won't charge any fee if we cancel our order on the testnet? Because I read the source code and found out that it will charge us some fee if we cancel an order. However, I tried on the testnet DEX, and it didn't charge me any fee when I canceled my order.

Nguyen Sy Thanh Son

@thanhson1085

Yep, will charge the fee in v2.1

qiushui

@qiushui777

Well, by the way, May I ask TomoZ and TomoP is both finished in the lastest codes now?

Nguyen Sy Thanh Son

@thanhson1085

tomoz is finished

tomop not yet, will add in the repo soon

qiushui

@qiushui777

Ok, tomop is cool. Not seeing public chains having this kind of anonymous.

Nguyen Sy Thanh Son

@thanhson1085

Almost tomop code is in the repo: https://github.com/tomochain/tomop

but we will create a PR to tomochain repo soon

qiushui

@qiushui777

Thanks. Quickly checked the repo, looks like you added the bulletproof in the vm. Going to try the new feature. But hopefully you can have some tutorials on how to use it .

Nguyen Sy Thanh Son

@thanhson1085

Will share you the docs when it is available

Benjamin Cordes

@benjyz

is there an ICO contract for tomo implemented?

this one I assume

https://github.com/tomochain/trc21/blob/master/contracts/TRC21.sol

Nguyen Sy Thanh Son

@thanhson1085

It is trc21 token contract

Benjamin Cordes

@benjyz

right, the token itself. any public implementation of an ICO contract i.e. the funding

Nguyen Sy Thanh Son

@thanhson1085

currently no

qiushui

@qiushui777

The program on hackerone is closed? Are you going to launch it on any other platforms?

Nguyen Sy Thanh Son

@thanhson1085

Yes, We will public the program on Whitehub then share you the link soon

hisarkopite

@hisarkopite_twitter

@thanhson1085 , @khaihkd , i set up a tomochain private network , according to the docs , what is the difference between the owner of the masternodes and the signers ?

In the document , all 3 nodes are considered as masternodes , but the reward is only being given to one of the masternode's coinbase.
