This is due to an instability of the Etherscan service. We're busy upgrading our code to prevent this from happening. Expect a resolution in 1-2 days 💪🏻

The technology of #MultiVAC blockchain is unmatched 🌟
This pioneering initiative from our community member Ox13e highlights the extraordinary capabilities of $MTV storage modules 😎
#ultracheap #modular #CryptoAdoption
Deployed a test ERC-721 contract on #MultiVAC that dynamically mints #NFTs, and stores all image and metadata (~1700 bytes) on chain.
For under 0.001 $MTV
It would be very expensive, elsewhere.

Here's this week's technical Q&A content:In MultiVAC, does miner need to save complete blockchain data? If not, how does a miner validate transactions and produce blocks without complete data?
Shawn:
Miners do not need to save complete data. We have a very neat design that allows miners to validate transactions and generate new blocks without complete data.
In MultiVAC, miners are required to keep track of
• All block headers;
• Roots of all shards’ main Merkle trees;
• Merkle Paths as required to perform updates to the Merkle Roots of all shards.
At present, the above data does not exceed 100MB in total. Even with the continuous operation of MultiVAC, we estimate that the future data growth will not exceed 1GB/year. So the data stored by ordinary miner is very small.
Only storage nodes are required to be aware of all blocks, comprising all historical transactions. However, they only maintain and update transaction outputs whose accounts are in the shard they are responsible for. For this reason, storage nodes of different shards will have different main Merkle Trees because storage nodes are only responsible for updating the state of transactions in their shard. Once the state is updated, the block hash changes and is propagated up to the Merkle root, resulting in each storage node having recorded the same transactions but updating only the transactions that it is responsible for serving up. Storage nodes may then optionally choose to prune the records of transactions that it is not responsible for.
So how does the miner update the block?
Recall that miners store not only all block headers but also the Merkle root from all shards and some Merkle paths from all shards as required for bookkeeping. When a miner is a block proposer, he is responsible for producing a block whose header contains two Merkle roots: the root of the attached block Merkle tree and the shard’s new main Merkle root upon addition of the block. Miners must update state changes from newly spent transactions when calculating the new main Merkle root. In addition, Merkle roots of blocks received from other shards must be appended to miners’ local versions of that shard’s Merkle root and Merkle paths in order to stay consistent with the other shards. Finally, the miner’s pending transaction pool consists of Merkle paths generated according to the current Merkle tree. After a new block is confirmed, these Merkle paths need to be updated in order for the system to stay consistent. These comprise a miner’s update tasks in MultiVAC. MultiVAC designs a process allowing miners to update their local state without knowledge of the whole Merkle tree. To do this, the miner requires the following information:
• The Merkle paths of all inputs spent in a miner’s newly generated block.
• All roots of block Merkle trees included in block headers received from other shards since the miner’s last update.
• The right-most Merkle path of each shard’s top main Merkle tree, that is, the Merkle path marking the locations where new blocks should be added in each shard. These provided by the shard’s storage node when the miner first joins the shard.
You can find more details in Section 4.3 of the MultiVAC Yellowpaper:

Here's the summary of this week's Tech Issues AMA.
1.) MTVs websocket (wss://websocket.mtv.ac) seems to be configured to only accept incoming connections from 'localhost', which means I can't acess it on my service frontend (using a browser). Is it the expected behavior? Is there any way I get access rights from a different origin?
Shawn: We have responded to your question by mail. However, we need to disclose our answer: our websocket server rejects users from cross-site requests for safety reasons. If it is really necessary to request on-chain data on the client side, I recommend using the RPC server instead of directly connecting to the websocket server by initiating client requests on the browser page, which may have greater security risks. The same goes for Ethereum's default settings. The websocket server is only for server-side applications. However, if you think it is really necessary, you can contact us to ask for an archival node, and you can set up this node for your users to connect to.

2.) Will we get a blockchain Explorer like etherscan, bscscan and ftmscan?
Shawn: We are still in communication with the etherscan team, but their offer is way above our expectations (millions of dollars per year) and is currently very busy and has not been able to work with us in recent quarters. We are still striving for the possibility of further cooperation. Additionally, our community is building new browser projects that are expected to provide more functionality. In any case, we are working hard to build a new explorer and are committed to providing a better on-chain application experience for everyone.
3.) Some people told that the whole MTV network runs on one server. Into the last AMA you told that the network will add automatically so many nodes as needed. How many server you have ready for this and are they hosted at different locations?
Shawn: We have thousands of nodes running on hundreds of servers spread across Asia, North America, Europe. We have used many different cloud service providers such as Google Cloud, Amazon EC2, and Alibaba Cloud. MultiVAC's network can resist force majeure such as earthquakes, storms, tsunamis and other regional natural disasters.
To say we only have one server is really ridiculous. Just an insult to us.
4.) As per last questions, it was stated that the gas limit for a single transaction is about 4 million which limit it to ~480 transfers per call & increasing this will increase the size of a single block, affecting broadcast speed. Is the broadcast speed determined by gas per block or net gas of total blocks (all shards)? (i.e. do 10,000,000,000 blocks with a blocksize of 1 process faster than 1 block with a block size of 10,000,000,000).
Shawn: The more gas a single block has, the larger the block may be (but this is not absolute). The larger the block, the more time it takes to propagate. Just like the difference between BCH and BTC, the block of BTC is only 1MB, while the block of BCH can be very large. For a block generation period of 10 minutes, a slightly larger block is fine. But for the 3-second MultiVAC network, once our block is too large, when the entire network is completely decentralized in the future, it may become a problem whether our miner node can receive the block in time.
I think at this stage we are confident to increase the gas limit of a single block, so that a single contract can run more content. However, we still make this decision cautiously, because it is not necessary to do so at present, but it may bring risks.
