blockchain aion p2p aion-networks

aion's Introduction

Aion

Mainstream adoption of blockchains has been limited because of scalability, privacy, and interoperability challenges. Aion is a multi-tier blockchain network designed to address these challenges.

Core to our hypothesis is the idea that many blockchains will be created to solve unique business challenges within unique industries. As such, the Aion network is designed to support custom blockchain architectures while providing a trustless mechanism for cross-chain interoperability.

The Aion White Papers provides more details regarding our design and project roadmap.

This repository contains the main (Java) kernel implementation and releases for the Aion Network.

System Requirements

Ubuntu 16.04 or a later version

Getting Started

Blockchain node concept

Developers

If you're interested in building Open Applications, powered by Aion:

Visit the Developer site of The Open Application Network : developer.theoan.com

If you're interested in making improvements to the Java Implementation of Aion:

Refer to the Build Aion kernel from source wiki for information on building this source code to a native binary or Docker image
Refer to the Installation wiki for a guide on installing and configuring the kernel.
The Owner's Manual wiki will include further instructions and details on working with the kernel.

Please refer to the wiki pages for further documentation on mining/validating, using the Web3 API, command line options, etc.

aion's Issues

NullPointerException

eth.getBlock has stopped working

The eth.getBlock operation has stopped working in the web3 included in the aion-v0.1.11-2018-02-16.tar.bz2 version of the testnet binaries:

aion-127.0.0.1:8545> eth.getBlock(0)
Error: Invalid JSON RPC response: undefined
    at Object.InvalidResponse (/home/ubuntu/aion/web3/lib/web3/errors.js:38:16)
    at HttpProvider.send (/home/ubuntu/aion/web3/lib/web3/httpprovider.js:91:22)
    at RequestManager.send (/home/ubuntu/aion/web3/lib/web3/requestmanager.js:58:32)
    at Eth.send [as getBlock] (/home/ubuntu/aion/web3/lib/web3/method.js:145:58)

It used to work fine in both versions 0.1.10 and 0.1.8.

I'm sorry if this is not the right place to report this, I was not sure about reporting this here or at aion_web3.

sendRawTransaction not changing state

when calling sendRawTransaction the kernel logs:

18-02-23 09:28:50.103 DEBUG API [rpc-server]: <request mth=[eth_sendRawTransaction] id=5 params=["0xf8a500a0b075f94677fa10743b0466b3ad1e7206816352a1bcb374d0cecf565f072d19219131303030303030303030303030303030308088000565bde881ffd98252088001b860b075f94677fa10743b0466b3ad1e7206816352a1bcb374d0cecf565f072d19239033abbcba5eaa2496ecc97a171ac0c2b0e8d2447755890fe1983b410187ef721651c7f31602736dc69e4df36c658e844c8aa7ebdcff57f6608267a3a4af7209"]>

But no state change happens.

when calling web3.eth.sendTransaction, kernel logs

18-02-23 09:34:43.907 DEBUG API [rpc-server]: <request mth=[eth_sendTransaction] id=4 params=[{"data":"","gas":"0x7530","from":"0xb075f94677fa10743b0466b3ad1e7206816352a1bcb374d0cecf565f072d1923","to":"0xb075f94677fa10743b0466b3ad1e7206816352a1bcb374d0cecf565f072d1921","value":"0xde0b6b3a7640000","nonce":"0x0","gasPrice":"0xa"}]>

and state does change

equihash.so migrato from libsodium to use same blake2b function in modCrypto

This change will help clean up the unnecessary dependency in :
https://github.com/aionnetwork/aion/tree/dev/native/linux/sodium/sodium
by replace blake2b function from libsodium to libblake2b.

Transactions Dropped

When running the transaction generator script, it works for some time, and then eventually the transactions get dropped from the pool, so they are not stored in the blocks.

I was able to temporarily solve this by downloading a version of JDK 9.0.4 and copying the lib folder over to rt

tr: Illegal byte sequence

When trying to run the ./generateId.sh script I get:
tr: Illegal byte sequence D----

For now I found a solution? here: https://www.real-world-systems.com/docs/tr.1.html

The fix seems to be to run export LC_ALL=C

AbstractTxTask need decouple from modAionImpl --> BroadcastTx, and move into modMcf

AbstractTxTask is the generic design for transaction broadcast, should not tied to aion zero's broadcast tx type and need move into modMcf.

those error exist when sync blocks from p2p network.

The first account I just added to the config/config.xml in the mining section. After I noticed it went to 0 I created a new account through the kernel and then replaced the first account with this new one in config/config.xml. Again the account went to 0 after a while.

I'm not seeing any error messages appear in the kernel miner, but it is possible there were some because I can't scroll that far up anymore.

Not sure what it is, but thought I'd post an issue for it.

balance not being imported

Refer to this issue I reported here:

https://forum.aion.network/t/new-kernel-version-account-missing/218/6

Not sure if this was fixed but whenever you import an account to a new kernel the balance is not transferring over.

modP2p, reputation based peer management.

Not all peers should be treat as equal priority.

The reputation based peer priority management will treat peers based on their contribution to the network and take different priority level when sync , transaction broadcast etc.

reputation index include :

1.) connections of peers.
2.) new block propagated.
3.) network latency.
4.) total bandwidth.
5.) sync list always on main chain.
6.) valid transaction rate.

Updating of wiki

Hi,

May I know what's the preferred way to issue "change requests" for the wiki? As I am unable to edit or issue a PR for the wiki, is there a better way to suggest changes to the wiki other than opening up an issue?

In https://github.com/aionnetwork/aion/wiki/Internal-Miner, under miner-address: the wallet address that will collect AION for mining blocks I'd like to make a suggestion to add the following information "To create a new wallet, run ./aion.sh -a create. To import an existing wallet, please refer to https://github.com/aionnetwork/aion/wiki/Importing-Accounts"

Cheers,
John

Setting up AION first time and getting this error. This does not specify the port that's already in use.

Update:

			<ip>127.0.0.1</ip>
			<port>3030[X]</port>
			<discover>false</discover>

Chaging port to 3030[X] (X:0-9) fixed the error.
