Ordered M21S, 1 Sept batch, still haven't shipped.
Has anyone received any M21S?

yaaaaaah
Where are the blooocks, wth. Sorry Kano but this is painful.

UPDATE
Spoke with them today, all is well, I think they were working on their mining setup and client access via Awesome Miner panel. I can now access my miner.

I've been mining with them for a few months and initially they (Wesley) was very responsive. I spoke with him several times on the phone and Wha. However lately I'm getting no response. The miner is running though and I can see coins being paid to my wallet.

Now I have doubts over my additional miners, whether to send there or elsewhere.

Not an ideal way to build trust among the client base.

Mining now with an A3 sucks balls, 1500-1600 SC per day, $30 bucks basically. Hard to justify the price, hard to even reach break even.

One would need to really believe Siacoin will appreciate A LOT.

Do you plan to support Dragonmint once it's released?

To assure Bitcoin remains decentralised, blocks need to remain small enough for anyone to run a full node.

How does this then co-exist with the increasing block sizes on Segwit (1X)? There are now block sizes above 1MB. I saw 1.6MB the other day.

Doesn't this notion counter decentralisation?

I'm curious to learn more about the block size under Segwit, any pointers appreciated.

Agree 100%. Sidechains is the path to exploit Bitcoin and its blockchain.

I'm reading up now on Bitcoin, found the Wiki, /scripts. It's like a french cook book 

Thanks again for taking your time to read my question and answering (twice).

Thank you MaryChris, helpful analogy.

While I do appreciate the innovation going on on the Ethereum blockchain I am squarely focussed on Bitcoin as it is truly decentralised. I want to make use of the Bitcoin blockchain for innovation. It's hard. In there lies success.

After some more research I came across a few articles that I believe answer my original question:

1. OpenTimestamps Has Timestamped the Entire Internet Archive

...As a result, almost the entire Internet Archive is now hashed into Bitcoin’s blockchain. Anyone can take any document from the Internet Archive and verify that it existed in its current form four weeks ago. If the hash checks out, the document has not been altered since, nor could it have been created later."

A different article on the same: https://petertodd.org/2017/carbon-dating-the-internet-archive-with-opentimestamps


2. Embedding custom data in Bitcoin blocks

https://bitcoin.stackexchange.com/questions/18/how-can-one-embed-custom-data-in-block-headers


My conclusion is that it is indeed possible to use the Bitcoin blockchain to record information.

This is GOOD.

Very clear, thank you.

On the note of using blockchain for other use cases than Bitcoin, I found these two articles that throw a wet blanket over the blockchain-but-not-bitcoin hype:

"Talking about “blockchain architectures” could actually be a codeword for “MySQL”. Everything that these vendors offer can be done in a MySQL database centrally controlled and secured with GPG. I have described how this would work in a previous essay ."

"Blockchain consultants have built prototypes for stock trading, asset registry, voting and payment clearance. But none of them have been commercially deployed because they are more expensive than simpler methods relying on established database and software stacks, as the government of Vermont recently concluded."

I'm trying to understand if there is a way to use the Bitcoin blockchain to record information. Say I am a business and would like to publish information to my clients through the Bitcoin blockchain; information that would therefore 1) be publicly available, 2) fully trustworthy (rather trustless) since verified and part of the Bitcoin network, and 3) be hashed/illegible to anyone but the client with the right key.

Let's take an example. Is it possible to use Bitcoin for example in a supply chain tracking business?

I guess what I am asking is, is it possible to use the Bitcoin blockchain for other use cases than as output of Bitcoin nodes verifying a new block and locking it to its predecessor?

I tried to search but didn't find anything (or I'm not a good searcher).

Thanks for any help.
