What is PMC mining?
- PMC uses Proof of Transaction consensus. It is the more block reward transaction, aka mining, the more power your phone obtains. Block reward happens when your phone wins a block slot. It is an open competing process based on Log(2, 2 + Current Power) as weight. This gives some advantage to beginners.

What is top 1000 accounts as miner?
- Version 1 PMC only accept top 1000 balance accounts to be miners. If a chain exceed 1000 users, your balance has to be high enough to be in top 1000 to mine and keep the coins. This does not affect chatting qualification. Therefore, for each city’s PMC, there are only 1000 miners with unlimited followers.
- In version 2, this will increase to 10,000 accounts (1000 x 10 shards with 100 replicas), based on IP2 protocol.
- In version 3, this will be 1m (10,000 x 100 shards with 100 replicas).

Why is forking and unstable balance or power?
- Mining competition causes this. Each state need more future blocks to confirm it to be final. We can use TX Confirmation Rate( Current time - TX time)/3Hours as an estimation of state robustness.

It is estimated one phone can mine 100 chains at the same time. It is not energy focused, it is proof of transaction algo lite protocol. https://taucoin.io/tech

In TAUcoin, mobile mining is defined as a hashing process on combined blockchain history and miner public key associated with transactions recorded on chain. It shares the same nature in bitcoin hashing, but mining power is generated from the transaction history rather than chips hashing strength or staking coins. This is a new consensus in exploration and still early to see its full potential. However, the experimental facts collected so far proves that it consumes insignificant computation and bandwidth. Proof of transaction(POT) mobile mining according the white paper is able to establish internal transaction market for all participants by including three types of block rewards. The needs of mobile mining derive from the lack of infrastructure in most part of the developing world and urgent needs of un-banked population. This is the "first contact" for those population to feel permission-less banking and trust-less verification experience at the same time through POT crypto currency.

In TAU mobile mining, there are two types of block reward: 1. mining reward which gives to block winner. 2. trx participation reward which gives to the address cause the trx sender balance. this will changes to sharding reward in the future.
Therefore, the tau mobile reward is not concentrating to block winners, but everyone perform work making trx and sharding and mining.

One the 2nd day of mobile mining turning on, we have got 1400 miners.
In the crypto world, not many people having experiences of true mining which is verifying transaction on global blockchain. I think we did it in taucoin.
We decided to start with slow main-net speed to make sure it is stable. Then we will implement ipfs sharding on it.

In my knowledge, all coin mining requires public IP address for nodes to communicate with each others on IP network, that is Internet. It is required for BTC, ETC, EOS and all as I know. On today’s Internet, only server has public IP, and blockchain network consensus is really built on “server to server”. You wallet is a client connecting to one of those servers, therefore wallet is not decentralized neither have the full picture of the pubic ledger to running by itself.
Clearly, good wallet shall run on mobile phones. However, mobile phone does not have “real IP address” due to IPv4 network is not able to provide that many IP addresses. IPv6 needs many years to come, so that the mobile industry using NAT, network address translation, to make many phones sharing one public IP and giving cell phone internal IP address behind firewall. Without IP address, mobile phone can only be client and not able to be a full mining node on public internet. Different cell phones behind firewall need centralized server to communicate to each other such as you see in whatsup and wechat.
TAUcoin is solving this industry bottleneck, to build true “client to client, server-less” networking allow blockchain to be maintained on mobile phone systems without any super node software. Every wallet is an full node running on mobile phone behind NAT firewall using internal IP address. So that we makes “server”, “client” and “wallet” all the same to achieve true decentalizaton.
How are we going to do that? Please stay tuned on TAU mainnet.

We spend 2 days on solving "mobile mining" behind firewall NAT. All crypto mining i see today require a real ip address, however all cell phones does not have a real IP, they are using NAT public IP in each connection. we need to adopt UDP hole punching to allow cell phone community with each other for consensus.
So our major innovation includes behind NAT p2p networking and POT block design.

welcome to the debate. we will enter exchange when community member reach 1 million. during mean time, we shall focus on technology.
Welcome to debate on "total consensus strength" TCS, https://medium.com/@davidwu_30530/new-idea-the-total-consensus-strength-tcs-among-pow-pos-and-pot-f24c7949b93f

Nice point, we decided to not adding UTXO, zero-knowledge proof or ring signature into settlement layers, it will be fully transparent. if someone need full anonymity, they can exchange to other coins.

Is privacy is conflict to transparency?  if transparency is corner stone for decentralization/democracy, shall we consider privacy is conflict to decentralization?
I love to see more debate on this?  UTXO is semi privacy, but eth account system is transparent, which is more decentralized?

we realize more and more "decentralizing" is the key in the blockchain and crypto through recent market move. therefore, we need to make mobile mining upmost importance.
To make each miner best user experiences and allow every phone be able to mine, I will propose to dev to reduce block size to 1kb per minute to make really light on mobile ming. that you do not have to worry bandwidth data.
during the same time, we will change web wallet to fee less fast payment platform.
with super decentrazlizing on the mainnet, and fast speed on centralized web wallet, we make "decetral- consensus-scaling" triangle balanced.
1KB/minute is bold move, we can expect community to fork out to high block size in the future if truly needed. I believe there are enough drivers to fork up to high block size. Now we need to make decentralized technology work first, which is largely missing in the industry.

quote: While he (BM) only gave people some vague information about how this new hypothetical token would be, he described it as something that would be immutable, limited to the role of being a proper digital currency and non-programmable.

Dan Larimer finally decided to do a currency rather than a global computer. that is why learned $4B paid by the community. Tau is targeting to be currency only from day one. i am glad we are on right track.
Now POW is volatile, POS-eth might never come out, dPOS is consider not a blockchain and tested by Whiteblock to report it is not much faster than eth, POT is one the way to the future...

dPOS can do high volume big blocks in short time, that is why they are better for dAPP to operate. settlement layer require decentralized participation, tau is more focus on the "decentralized" part of the tri-angle.
it is complicated to debate how many miners are enough, i do not know either, how many TV channels do we really need? 8, 100 or a million?

Giving up high volume transaction numbers on main net is a big bet. Most of startup project dares not do that, but Satoshi did it through bitcoin in return for consensus. One blockchain to satisfy all DCS (decentralized, consensus and scaling) is impossible, there is math proof on that. One ecosystem of block chains can do that. Assume there is an ecosystem in the future, all we need to do is to pick up a position. TAUcoin picks up "decentralization" and consensus, which force us to run mobile mining and 10kb block size, no high volume as result.

I personally do like dPOS for application say social, commerce and search engine. dPOS needs great enterpreneur to build venture to fight current giants. I do hope steem can win, but it seems their product is loosing traffic and founding team is gone.

10kb per minute on settlement layer is new but good for decentralization. The triangle, "decentralizing, consistent and scale", we would choose first two and trade off scaling. the future world in my imaging will be major application such as search engine, social and commerce running on dPOS semi-decentral consensus to gain scaling. TAU could use side-chain to settle with dPOS tokens to gain speed and other features. 10KB per minute is possible to gain millions of miners to join. so does crypto currency need millions of miner to protect it? or just less than 100 miners can hold the trust of the world?

I would argue:
1. BTC: 70% consistent, 20% decentralized, 10% scale
2. dPOS: 50% scale, 40% consistent, 10% decentral
3. TAU: 70% decentral, 20% consistent, 10% scale.

I love the feedback on keeping us focused and simple as basic coin settlement layer.

A key decision is made and very bold. "reduce the block size to 10kb" aims to support massive decentralized mobile nodes mining.
Peer to peer communication among millions of mobile devices require smaller block size. This is to increase data availability, resulting to provide high security. we believe security is upmost importance, given the recent BCH 51% attack show. We adjust our spirit to "light and secure". this puts us in a very unique position comparing to other coins increasing block size, which will cause centralization, due to less nodes have full capture of blocks on time. The reason for 10kb is average ethereum block is 50kb. As an experimental currency, we want to start with high security, 10kb makes us look not sexy, but 10kb blocks size in a pure mobile environment is very cool.
what is your feedback?

so why not just using smart contract in side chain? shall tau main net settlement layer support smart contract at all? UTXO is not able to support Turing complete smart contract. TAU is using utxo now.

are we going to support smart contract? love to hear feedback. pro and cons

... discussion on speed up ...
Bitcoin lightning network aims to provide fast payment routing and channel. Many bitcoin wallets start to support connect to LN.
TAU coin mobile miner is naturally fitting to provide payment channel on mobile network. so that, pot settlement layer will focus on security, then lightning network can speed up the transactions.

... continue the transaction spam discussion...
in email work, spam is popular because of the cost of sending email is close to zero. in TAU network, the cost of spam transaction is not cost zero, that require transaction fee satisfying miners. making lots of transaction increasing mining power is viewed as action to invest into tau future.
what is your idea?
