Bà Tân | : Start session 1 AMA
Bà Tân | : 5 questions in session 1
BĂ Tân | : Question 1. Can you introduce the ZPoW consensus algorithm in SCDO? Whatâs its advantage over other existing PoW algorithms?
Alvin_SCDO : ZPoW consensus algorithm is a new PoW algorithm proposed by SCDO.
It has two development phases. We have finished the development of the first phase.
At the first phase, the miners need to search for a nonce such that the determinant of the corresponding random matrix meets a certain target. Each random matrix has to be generated sequentially to prevent parallel computation in each nonce search.
The determinants of random matrices have nice statistical features to guarantee the decentralization of the network. Also, the scientific Gaussian distribution of the target value will anti superpower mining nodeâs dominant advantage, which will further protect the network and decentralize SCDO network.
The second phase of ZPoW will be a framework mixing different PoW algorithms. The difficulty of each PoW algorithm is adjusted by a dynamic mechanism so that itâs hard to produce continuous blocks on the same PoW algorithm. Another mechanism will be developed to prevent the miners from switching among the algorithms.
This is our innovative framework to prevent 51% attack. Compared to other PoW algorithms, it also makes the design of ASIC machines extremely difficult.
Done, thanks!
BĂ Tân | : Question 2. What is the difference between SCDOâs sharding technology and other sharding technologies? What problem does it solve?
X-SCDO : As we all know, the transaction speed of many PoW-type blockchains is becoming a bottleneck. In SCDO, we use PoW as consensus algorithm, and it has sharding protocol which can help scale up SCDO mainnet horizontally
For sharding, consistent sharding is one of most important requirement which needs all shards to be consistent.
Currently we have 4 shards which increases the TPS of mainnet to a great extent (~k transaction/second). In SCDO sharding protocol, each shard maintains local data (on local chain), and stores the header information of other shards (on light chains) in order to perform cross-shard interaction and verification.
The sharding protocol supports both intra-shard transactions and inter-shard transactions (debts).
Other sharding protocols either have a relay chain for other shards or has no consistency of all shards.
But in SCDO, all the shards are homogeneous and consistent. It makes adding extra shards very easy. In the future, more shards can be added if needed.
The communication between different shards also requires much less time and data backup. This make the network very fast and secure.
Done, Thanks
BĂ Tân | : Question 3. Can you introduce whatâs new in SCDO Stem subchain protocol? And compare it with other sidechain/parachain protocols ?
Alvin_SCDO : SCDO Stem subchain protocol is a layer-2 solution to scale up SCDO. It enables everyone to create their own subchains, applications and ecologies.
Each subchain will have a corresponding smart contract (we call it Stem smart contract) deployed on SCDO main chains. The main chain keeps track of the subchain information and handles some requests via this Stem smart contract.
Compared to other layer-2 protocols, Stem protocol has the following advantages:
1)Subchains will have full support for smart contracts while the main chain provides strong asset protection for the subchain.
This is achieved via special one-round interactive challenge mechanism. The classic Plasma protocols cannot support smart contracts for the sidechains, for they cannot guarantee a safe exit with smart contract enabled.
2) The information that SCDO main chain needs to store is light-weighted. Not like Roll-up, we donât require all the information to be stored on main chains, or the smart contracts to be executed by the main chainâs virtual machine.
And only some accounts in the subchains are tracked per the usersâ requests. This property is of great importance because it doesnât transfer the data burden from subchains to main chains.
3) Stem protocol allows tokens from different subchains to be exchanged in a decentralized way. The Stem smart contract holds the mapped tokens of the subchain tokens.
Users can exchange their mapped tokens in a decentralized exchange. Or they can lock the mapped tokens to get subchain tokens.
done, thanks !
BĂ Tân | : Question 4. Compared to Ethereum/Polkadot, what is SCDOâs greatest advantage?
X-SCDO : SCDO is innovative in many ways. It has a PoW-based sharding protocol that supports high volume of transactions. While Ethereum only has one shard and Polkadot only supports a limited number of parachains
So SCDO has higher transaction speed and throughput, and more decentralized due to the innovative PoW consensus algorithm.
Furthermore, SCDOâs Stem subchain protocol can easily support thousands of subchains which use mainnet as secure base. So SCDO can support all kinds of eco-system applications, in this way, SCDO netword can be vertically scaled up.
Done. Thanks
Bà Tân | : Question 5. What is the current development status ?
Alvin_SCDO : Our mainnet is going to launch recently! It has ZPoW phase I and sharding protocol ready. Currently, we are developing Stem subchain protocol and SDKs for our mainnet.
Our wallets can be downloaded here: https://github.com/scdoproject/scdowallet/releases
More wallet versions will be released in the future.
Done, thanks!

Bà Tân | : We will move on to session 2
Sessions 2: We will pick 5 Best Question from our members on Our Tweet (https://twitter.com/IM_Communityitw/status/1336237915983106048).
Diana_SCDO : Please follow SCDO Twitter: https://twitter.com/officialscdo?s=21. More updates will be posted there!
Bà Tân | : Question 1 : @CaoHa27628628
Whatâs your vision ultimately? What is http://SCDO.pro trying to achieve in the longer term and how do you plan to get there?
How will your ultimate vision and mission make a difference in the world?
Alvin_SCDO : SCDO wants to be a scalable, secure and decentralized platform that gets real world adoptions. In the current blockchain domain, only a few public blockchains are able to form complex application ecologies.
With our innovative technologies, SCDO has the ambition to join this group. To achieve this goal, we will provide powerful developer tools and connect with other blockchain ecologies.
For example, SCDO is evm-compatible and our team will make the migration of applications from Ethereum to SCDO very easy.
But more importantly, We will keep our technologies and ecology unique so that users always stay in our ecology.
Done, thanks!
Bà Tân | : Question 2 : @CabreraEdelis
What are the steps that must be done to do SCDO mining?
X-SCDO : For mining SCDO, the steps is quite simple and straightforward.
1.One machine which can conduct scientific computation with some storage for blockchain data.
2.Download the executable node file(https://github.com/scdoproject/go-scdo/releases/) Or Build it using source code (https://github.com/scdoproject/go-scdo)
3.Configure your account json file
4.Run your node. That is it.
first of all, (As we mentioned before) SCDO has an original PoW consensus algorithm (ZPoW) that uses the properties of random matrices to guarantee the decentralization of the network. So Even an PC can join into SCDO network for mining.
The Difficulty adjustment equation will automatically adjust the computation target based on the network total computing power;
Not hard to mine SCDO because SCDO is very CPU friendly and encourage each individual to mine.
And the Gaussian-style distribution of target will make sure the rewards are not dominated by any superpower node. Moreover, Each random matrix has to be generated sequentially to prevent parallel computation in each nonce search.
The upgraded ZPoW will be a framework mixing different PoW algorithms. The difficulty of each PoW algorithm is adjusted by a dynamic mechanism so that itâs hard to produce continuous blocks on the same PoW algorithm
Done, thanks
Bà Tân | : Question 3. @nguyenthanhtamz
There are 3 core issues prevalent in crypto and blockchain:
Security, Interoperability, and Scalability. so How does Your Project plan to overcome these issues?
X-SCDO : let me continue to ask this question
Security: Along with P2P network, the PoW consensus algorithm is the security foundation of blockchain platform, since this will prevent centralized frauds. (As introduced in first quesion 1)
SCDO has an original PoW consensus algorithm (ZPoW) that uses the properties of random matrices to guarantee the decentralization of the network. ZPoW will be developed into a mixed PoW consensus and multi-difficulty adjustment framework. It will make 51% attack extremely difficult.
Interoperability: Since SCDO has the characteristics of high throughput and Turing-complete Smart Contract Operations. All applications can be smoothly deployed on SCDO without any barriers.
In this way, we can use all kinds of Smart Contracts to interoperate between SCDO and other blockchain platforms. Furthermore, SCDO has an heterostructure network: main net and multiply heterogeneous layer2 subchain (Stem subchain). User can not only deploy the applications on SCDO main net, but also create his/her blockchain based on his/her applications model. All Stem subchains can also interoperate with SCDO as well. So SCDO has a lot of flexibilities and convenience;
Scalability: As we discussed above, SCDO network can be scaled up use SCDO sharding protocol horizontally and also scaled up using Stem subchain vertically. (pls see the sharding and subchain discussion above)
Done, thanks
Bà Tân | : Question 4. @YenTatooLeYen
4. As a community Member, How can I help in Projectâs Growth ? What role does community can play in the SCDO ecosystem ?
Alvin_SCDO : The community members play an important role in SCDOâs ecology. Developers are welcome to deploy their applications on SCDO blockchain and even contribute directly to our project code.
They can create and maintain their own subchains with the support of SCDO Stem subchain protocol.
We would also like to listen to your brilliant business ideas.
done, thank you!
Bà Tân | : Question 5. @cauvova1
Can you give an overview of $SCDO Token tokenomics?
Will the design of the token rise and fall with the success of the platform, does it include any scarce paths, such as equity, storage or burning?
Diana_SCDO : SCDO has an auditable supply: 300,000,000 SCDOs in total and ALL for mining.
3150000 blocks/era and block reward at each era follows [6, 4, 3, 2.5, 2, 2, 1.5, 1.5] order until reaches the last reward of 1.5 SCDOs.
Done, thanks!

And can follow our Twitter: https://twitter.com/officialscdo?s=21
Q1. How can users stay updated with this project? Are there channels, including local communities where users can get the latest updates??
Diana_SCDO : You can easily stay updated by 1âŁď¸entering our official telegram channel: https://t.me/scdogroup
and announcement channelďź
Q2. How many killer features of Your project that makes it ahead of its competitors? Could you tell us 2â3 features?
X-SCDO : 1.Decentralization(Innovative ZPoW consensus algorithm) 2.Scalability and Fast(Sharding and Stem subchain) 3.Smart Contracts(fully comptiable with EVM)
Q3. What is the problem that your project primarily focuses on?
X-SCDO : We believe blockchain is a infrastructure and still has some tech problem to deal with to forward its industrial applications. SCDO is born to solve this. 1. The mainnet is highly scalable with sharding protocal, TPS is comparable to centralized payment companies, like mastercard and VISA. 2. With Turing-complete smart contract, all industrial applications can be built on SCDO, It is also compitable with ethereum EVM, so all applications can be easily tranfered from Ethereum(with higher TPS, SCDO can handle more applications per seconds as well). 3. The subchain even scale up netword largely, since user can customize their own subchain for their own applications(supplychain, DeFi, Banking, Accounting, etc). Subchain can has its own structures and consensus algorithms, so the TPS can 10000 or even more. So applications can built freely on it. So SCDO is very good platform for applitions especially insdustrial applications, more applications will deployed, pls stay tunned
Q4. As we well know, many countries try to regulate blockchain activities, which has led to many different regulatory frameworks. How does SCDO deal with this situation?
Alvin_SCDO : SCDO is a public blockchain and doesnât have presale. You can get the tokens by mining or from the exchanges in the future.If you want to join the SCDO community, please obey the regulation of your country.
Q5. Can SCDO be implemented on other platforms/merchants like a dependent tool for business solution or its inseparable part of SCDO ecosystem ?
Alvin_SCDO : SCDO is an ecosystem including the SCDO mainnet, subchains, SDKs (wallets, scans, apis, developer tools). Thus, some parts may not be migrable to other projects. But SCDO would like to connect with other projects by building asset bridges.
