A transaction should have a contractRet field, so we can tell if the transaction is success.
But transaction da124c316ea64e5df700296376d0cf894215e241b50c6cf6c71ae0aa7021d815 do not have a contractRet field, the raw data from trongrid is below:

}

So the question is:

1. Is contractRet exists in every TransferContract transaction?
2. If not, how can we tell if a transaction is success?

What should the ByteMessage provide like? there's also no relevant documentation described......
https://github.com/tronprotocol/protocol/blob/master/api/api.proto

This library is older than the one present here : https://github.com/tronprotocol/java-tron/tree/develop/protocol/src/main/protos

In the latest version above RPC's like estimate_energy are available.

Encountered an issue with a stuck transaction on the Tron blockchain. The smart contract involved is here. You can view the transaction details here. The transaction status shows as "FAILED - TRANSACTION REVERT."

I am trying to execute TriggerConstantContract via gRPC protocol and having returned this error:

"A���=contract validate error: No contract or not a smart contract

I am setting addresses like this:

$sc = new TriggerSmartContract();
$sc->setOwnerAddress('41977C20977F412C2A1AA4EF3D49FEE5EC4C31CDFB');
$sc->setContractAddress('419E62BE7F4F103C36507CB2A753418791B1CDC182'); // USDT contract.

gRPC client is PHP library generated from this repo, but I think that's irrelevant.
I am using the latest stable release.

I have TriggerConstantContract working via HTTP but can't make it working using gRPC.

Why does the block in the GRPC protocol not add the txId field?

curl -X POST https://api.trongrid.io/wallet/updateBrokerage -d '{"owner_address":"TGj1Ej1qRzL9feLTLhjwgxXF4Ct6GTWg2U", "brokerage":20, "visible":true}'

The above command gives an error， owner_address is encoded in hex format, no error is reported.

Content of file ./install-googleapis.sh seems to be outdated and I see two problems there:

cannot find package "github.com/grpc-ecosystem/grpc-gateway/protoc-gen-swagger"
(this package seems to be deprecated and replaced)

And

wget http://central.maven.org/maven2/com/google/api/grpc/googleapis-common-protos/0.0.3/googleapis-common-protos-0.0.3.jar

returns

--2020-12-24 19:02:17-- http://central.maven.org/maven2/com/google/api/grpc/googleapis-common-protos/0.0.3/googleapis-common-protos-0.0.3.jar
Resolving central.maven.org (central.maven.org)... failed: nodename nor servname provided, or not known.
wget: unable to resolve host address ‘central.maven.org

Can we have this fixed ?

unable to freeze trx to gain power,bandwidth from tronscan.org

Hi,

where are the C based language API's for the Tron protocol?

I am getting error on line with BELOW_THAN_ME = 0X24; (Tron.proto file):
Illegal id 0X24. Fixed just changing to 0x24, but i dont know what it can break

Здрастуйте. Подскажите на SefePal столкнулися с такой проблемой, при передаче или выводе USDT мне сразу выбивает SIGEEROR. Дело ещё такого рода что при покупке TRX деньги у меня с карты уходят но TRX не появляется.. Что может быть?

Whenever the contract is created these are the parameters it returns:
{
"ownerAddress": "TGAGGMBKK1fq2Ym3ZQDzTWa55R68UB5xWU",
"firstTokenId": "SEED",
"firstTokenBalance": 1500,
"secondTokenId": "_",
"secondTokenBalance": 7500000000,
"contractType": 41,
"hash": "54d41e4408e74de3ec9d8cf25362676f41e37a72d8dcb05b09ce10db603c5a6f",
"time": 1541743302279
}

...but it lacks the most important one which is the 'exchangeId'. with it we can get track the secondary token which is not in the ExchangeTransactionContract.

如何安装这些依赖呢

A very important feature is missing here. How can an SR / SRC view its voters without accessing third party vendors? This is important!

This repo is underdocumented.

• Missing description (github repo)
• README incomplete (missing pointers to documentation)
• The two protocol md files in root (English, Chinese) describing the protocol are essentially redundant (description should be move right into the files, like https://github.com/tronprotocol/protocol/blob/master/core/Tron.proto)

Please be aware that all this makes a quite sloppy impression.

Tronscan team suggested I raise the suggestion / recommendation here.

Allow the community to support TRX buy holding on to their TRX for longer periods of time in exchange for agreed TRX dividends by percentage of TRX held.

For example if you have 1000 TRX and freeze for:-

6 months - 1% = 10 TRX dividends
12 months - 2.5% = 25 TRX dividends
24 months - 6% = 60 TRX

Rather than set a set % you could tie this into a percentage of how much TRX has gained in the period. If there is no gain then no dividends are awarded (given that long term investors want to support Tron they may not mind if nothing is distributed if within the frozen period the price drops. They could be given an additional % if they opt to freeze again and continue their support.

When using grpcio_tools module to generate code, there are so many missing files using the following command:
python -m grpc_tools.protoc --proto_path=googleapis:. --python_out=apps/trx/protocol/ --grpc_python_out=apps/trx/protocol/ -I. api/api.proto --include_imports

Is there any proper method to get this work?

Is it possible to modify the existing query "/wallet/listwitnesses" and add values?

Many queries are necessary to keep your app in the Votes section up to date.

1x query "Listwitnesses" - ~220 entries
220x queries "GetAccount" - to get the name of each single candidate
220x queries "GetBrokerage" - to find out the current level of rewards.

These are 441 queries. If you could add the name and the brokerage info, it would only be 1 query.

I am trying to get go version of protoc files but the following error is returned:

 tron_protocol protoc -I=. --go_out=go_data api/api.proto 
protoc-gen-go: unable to determine Go import path for "google/api/http.proto"

Please specify either:
        • a "go_package" option in the .proto source file, or
        • a "M" argument on the command line.

Any idea how to fix this? Earlier I was able to use them for nodejs, but with golang no luck so far.
I have executed install scripts and file google/api/http.proto exists in my local path

(see title, and example follows.)

Protobuf protocol

The protocol of TRON is defined by Google Protobuf and contains a range of layers, from account, block to transfer.

There are 3 types of account—basic account, asset release account and contract account, and attributes included in each account are name, types, address, balance and related asset.

A basic account is able to apply to be a validation node, which has serval parameters, including extra attributes, public key, URL, voting statistics, history performance, etc.

      enum AccountType {
  
         Normal = 0;
  
         AssetIssue = 1;
  
         Contract = 2;
       
}
