Introduction
GOVM: golang virtual machine
The govm system uses a new blockchain architecture, a public BlockChain with high performance as its goal. Its theoretical TPS performance can exceed 2⁶⁴.
Mainnet is online.
No Premine, No ICO.

Background
Ethereum's sharding technology has no good final solution.
Due to the low performance of existing blockchains, one application per chain causes island problems.
What is needed is a system that can be scaled on demand to meet application usage.
If there are too many transactions, we can create a new chain to handle new transactions.
If 10 chains are not enough, we can create 10 million chains.
If Bitcoin is one road and Ethereum’s sharding technology is one road with multi-lane, then govm is road network(a lot of roads).

The Vision
We hope all in one.
As the foundation of the digital world, all trust relies on data.
It is hoped that the input data are fact data, which can be easily verified.
Enough Trusted Data Will Create a Trusted Digital World.

Solution
Isomorphic multi-chain.
The logical relations form a binary tree structure, and the depth of the tree can reach 64, so there can be at most 2 ^ 64 chains.
Each chain only needs to care about its parent chain and two child chains, so the chain processing is simple.
All chains have the same tokens and consensus, and tokens can be transferred arbitrarily.
Cross-chain transfers in the system do not need any validator/collator, and can be 100% reliable through technical solutions.



POW + POS as a consensus of homogeneous multi-chain solution, there are problems, it is easy to be attacked by POW, and too many blocks, it is easy to cause network congestion. The new consensus use DPOS + POW.
After the development of the new consensus, the project is technically restarted.

Technical comparison
Advantages of sharding technology: only one account is required in a system, can quickly increase system performance without affecting user use.
Disadvantages of sharding technology: It is only for simple parallel processing of transactions. The number of sharding side chains will be limited. If there are too many sharding side chains, the main chain will become a bottleneck; at the same time, its complete technical solution has not yet come out.
Advantages of cross-chain technology: It can pave the way for two different blockchains to bridge the gap and achieve intercommunication between different blockchains.
Disadvantages of cross-chain technology: It cannot resolve differences in consensus, computing power, and credibility between different blockchains. It requires the role of a supervisor and is suitable for small transactions.
Advantages of homogeneous multi-chain technology: The performance of the entire system depends on the number of chains, different chains have the same consensus, and virtual currencies can be arbitrarily transferred between different chains, and the performance can be much higher than the sharding technology. Different chains are relatively independent and can be deployed on different computers. Breaking through the bottleneck of ordinary computers(the TPS performance of ordinary computers is difficult to exceed 7000).
Disadvantages of homogeneous multi-chain technology: Each chain has an account, which easily leads to the scattered distribution of account funds on different chains.

HOW TO MINE IT?

[lengzhao]

document: http://govm.net/book/

[notsofast]

OK, this is something interesting. I will compile and mine a little.

Is the disk I/O load heavy? Or is it just heavy for the initial sync?

Why did you premine for 5 months?

Why did you premine for 5 months?

1. You can check the commit date on Github, which was released five months ago, but since our focus is on technology, there are only a handful of test users. First posted on a forum in China(https://blog.csdn.net/lengzhao/article/details/102494094).
2. there is no dedicated operations team and no dedicated translator, so you can see that the translation of the document is not good.
3. Now belongs to the early days, the disk load is not high, follow-up can be considered to run in different chains on different disks or machines.

But it is not yet in exchanges right? Even Chinese exchanges? What industries do you think will be attracted with this multi-chain parallelism concept? Because the more companies using your network, the more valuable it will be in the market? Do you have companies that you are in talk with to deploy your network?

1. It is not in any exchanges.
2. It will serve as a basic public chain, similar to Ethereum/EOS,Higher performance.
3. It allows a large number of applications to run together in a system, sharing information between contracts. 
There is no island problem, will be the foundation of the digital world

[Exadro]

new and still nothing else. can this be mined?

[lengzhao]

E:\Crypto\GOVM\database> ll database.exe
'll' is not recognized as an internal or external command,
operable program or batch file.

get error like that... what's wrong?

You can just look at database.exe exists. If exists, it is right.

That's because of the clearance issues. You can run the database.exe, do not register to become a service.

[cryptobtcnut]

Sync is slow, is there a bootstrap or a way to speed it up?

How big is the chain in total currently?

the first chain have 228664 blocks. The processed data size is about 2G. The system is account type, so each block needs to be processed.

Just double click database.exe, not double click install.sh?

how to know that it's synced?

[cryptobtcnut]

the first chain have 228664 blocks. The processed data size is about 2G. The system is account type, so each block needs to be processed.

Thanks, and roughly how much time should it take to sync from scratch on average PC?

[CRYcry]

It takes ages to sync. Any way to speed up the process?

Ordinary disk, about two days.Solid state drive, about one day.

I'm sorry, but there's no way to speed this up.
Because it is an account system, each block needs to be processed, so the speed is slower.

It is not good at all  May be you should think about the way to speed up sync. For exhample to sync blockchain from the end, like in TERA?
