New milestone | SAMAN 1.0 test network has been online, get ring internal heat

The Saman V1.0 test network has been successfully launched on April 19, which has been reported by mainstream media in the circle. More than 70+ industry KOL to Call. Saman’s visibility in the industry has been further enhanced. It is reported that after the successful launch of the test network, it is now conducting a comprehensive application development test and preparing for the subsequent recruitment of nodes. Let’s take a look at what the Samna 1.0 test net does.

NO.1, what is Saman?

In order to better understand the impact of the 1.0 test network on Saman, I first introduce Saman briefly:

Saman aims to create a new generation of underlying chain with the triangle balance of privacy, performance and extensibility, and realize an inclusive and diversified decentralized financial ecology through Saman. Hope to provide users with safe, efficient, easy to operate, developer-friendly decentralized financial public chain.

NO.2, what are Saman’s technical advantages?

Saman’s underlying blockchain uses a layered architecture, with the system chain at the bottom and the application chain at the top, separating transactions from smart contracts. In terms of consensus, RAFT consensus is often used in the alliance chain to provide high fault tolerance and flexibility of the system, while POS is used to solve the possible fork caused by the block of RAFT consensus. The combination of RAFT and POS algorithm provides a fully distributed consensus solution with high fault tolerance and sufficient fork resolution mechanism for Saman. Saman architecture includes system chain, event processing system, smart contract execution technology through application chain, sharding technology, cross-chain technology, security performance and API, etc. The different business logic is processed at the corresponding technical level, which greatly improves the performance and processing capacity of the whole system.

NO.3 features of the Saman 1.0 test network

Through the above introduction and technical characteristics of Saman, I believe that we have a more profound understanding of Saman. At the same time, we should also understand the obstacles and difficulties of its vision. Therefore, the launch of the 1.0 Beta Net is mainly to change the problems of high transaction fees, slow transaction speed and low throughput. Therefore, the 1.0 Beta Net has the following three characteristics:

1. Zero commission. As the name implies, the initiator of the transaction does not have to pledge or consume the basic currency of the network.

2. Speed trading, the average time of block is 5 seconds.

3, High throughput, when thousands of nodes exist to achieve more than 1400 TPS of transaction processing capacity.

NO.4. What problems does the Saman 1.0 test network solve?

It is believed that everyone has been suffering from the expensive and slow trading environment of Ethereum for a long time. Although the leader of this bull market is the decentralized finance which is thriving in Ethereum, the high commission fee of tens of dollars at every turn has blocked many small traders out of the door, making it impossible for the general public to really enjoy the dividends brought by the decentralized finance. So the Saman V1.0 test network offers new options

1. In terms of block output speed:

Saman has some innovations in consensus algorithms. Its RAFT consensus algorithm, combined with Proof of Entrusted Proof of Share (DPOS), is built on a network of 21 verification nodes. Blockout times in seconds can establish a high-speed infrastructure for the DEFI protocol. It also gives users a fast trading experience.

2. In terms of transaction fees:

In Saman, the use of GAS as a computing resource metering tool is still retained, but its handling fee related use is replaced and extended through the POWER mechanism. Power is more like a Power/Power concept, where non-energy energy is used up and represents the Power to use network resources (computing, storage, bandwidth, etc.). The more coins a user has, the more Power they have and the more network resources they can use. For example, the maximum Power value consumed in each transaction and the recovery rate after the Power is consumed will be greater. That said, a zero fee doesn’t mean you can use the network without paying anything. Users still have to pay to hold Saman. However, in the process of transaction, the user has to pay only a hundredth or even a thousandth of the Ethereum fee, but the transaction speed is much faster than Ethereum, the maximum TPS can reach 2,000 transactions per second. So Saman TestNet is a great choice for the average user.

NO.5, how to issue a token on the test network?

This test network can not only send Saman, but also issue tokens on the chain, but before issuing tokens, you need to prepare the following:

1.Prepare an address that holds native Saman tokens (sufficient power) 2.Information about token issuance (abbreviated full name, total issuance, decimal places)

Specific example steps

Note: The contract version needs to be <= 0.4.24

1.Modify the information in the example of token contract

contract SamanERC20Token is PausableToken {
function () public {
//if ether is sent to this address, send it back.
string public name;
uint8 public decimals=18;
string public symbol;
string public version = '1.0.0';
constructor(uint256 _totalSupply, string _name, string _symbol) public {
totalSupply = _totalSupply * 10 ** uint256(decimals);
balances[msg.sender] = totalSupply; // Give the creator all initial tokens
name = _name;
symbol = _symbol;
contract Erc20Token is SamanERC20Token {
constructor() public SamanERC20Token(10000, "ASD", "ASD") {


  • decimals=18 => decimals=8 Decimal place changed from default 18 to 8
  • SamanERC20Token(10000, "ASD", "ASD") {} The parameters in brackets are total amount of release, full name'', ```shorthand

2.Copy the modified contract and go to Ethereum Remix to compile the contract and copy the compiled bytecode

  • Step 1: Compile
  • Step 2: Select the byte code of the specified constructor
  • Step 3: Copy the corresponding bytecode

3.Deploy the contract in MySamanWallet

Web site:

  • Step 1: Enter the deployment contract page
  • Step 2: Paste bytecode and account private key
  • Step 3: Deploy signed transactions

4.Successfully issued

NO.6, about the successful release of the 1.0 test network after the feeling

Saman team is always striving to achieve an inclusive, diversified and decentralized financial ecosystem. From the pace of past product updates and the launch of this test network, we can tell that Saman is always sticking to the planned route. Although the journey is still far away, but with the emphasis of faith and the support of many users, I believe that with the advance of time, we will be able to reach the sea of stars.

SAMAN roadmap

SAMAN is dedicated to building the root for a pervasive decentralized Internet.
