Introduction
Bitcoin and other cryptocurrencies that followed Bitcoin solved third party problem for payments. They allow any two willing parties to transact directly with each other without the need for a trusted third party. The solution turned out to be so remarkable that it gave birth to a new economy entity - decentralized corporations. Each cryptocurrency is a measure of value of its decentralized corporation.
And now we have new third party problem. We do not have a convenient way to move a value from one decentralized corporation to another without the involvement of a third party - centralized cryptocurrency exchanges.
Trustless cross-chain trading known as atomic swap is first step to solve the problem. However it has two disadvantages: first, that it's rather slow; second, that trading can be canceled in the process of execution after the parties came to an agreement.
We need a cross-chain exchange that provides a user experience not inferior to the centralized exchanges.

Project goals

• Provide public blockchain based on popular NXT technology and codebase, whereas improving the initial token distribution by mining.
• Make built-in NXT assets (colored coins) exchange functional, by providing trustless deposit/withdrawal from other blockchains.
• Provide a near real time trading user experience.
• Give to the community a tool for obtaining income in a variety of coins, Etherum Classic and other.

Short technical summary
Metro is a hybrid between Proof-of-Stake based on NXT (Next) and Proof-of-Work originating in Bitcoin with modified Dark Gravity Wave difficulty formula.
Max circulation supply: 1,000,000,000 MTR
POW blocks:
Algo: keccak256
Frequency: 1 in 10 minutes
Block reward: 2,000 MTR
Block reward halving: each 200,000 blocks (3 years 10 months)
POS blocks:
Algo: Blind shooting (ARDOR, NXT)
Frequency: 1 in 3 seconds
Block reward source: transaction fee, trading fee (will be implemented in stage 4)

Roadmap
JULY 2017 – Concept and Research. (done)
JANUARY 2018 – Development start. (done)
MAY 2018 – White paper, announce (done)
JUNE 2018 – Stage 1: Hybrid POW/POS blockchain implementation. Open source code. (done)
JULY 2018 – Blockchain start. Airdrop. (done)
SEPTEMBER 2018 – Stage 2: Transmitting hubs.
DECEMBER 2018 – Stage 3: Real time trading platform.
MARCH 2019 – Stage 4: Two side peg with Ethereum Classic.

Stages
Stage 1: Hybrid POW/POS blockchain implementation. We need fast blocks to give user near real time trading experience. Proof-of-Stake gives us such ability. Proof-of-work has one advantage over the proof-of-stake — there is no need of additional data to check an eligibility of a block release and determine longest chain from the outside the blockchain. And we need this feature for blockchain pegging. Also Proof-of-Stake give us stake protection from 51 percent attack. So, we need hybrid blockchain.
Stage 2: Transmitting hubs. The larger the size of the peer-to-peer network, the longer it takes to distribute the block over it. The highest speed of block distribution is shown by Delegated POS blockchains. Delegates perform the block producers and block propagation hub roles. Unlike DPOS, we split the block produce function and the block propagation function. Traditionally, the function of block produce is performed by miners and forgers, and transmitting hubs are responsible only for their rapid delivery to all network participants.
Stage 3: Real time trading platform. We plan to provide a user experience not inferior to the centralized exchanges.
Stage 4: Two side peg with Ethereum Classic. Ethereum Classic will be the first cryptocurrency pegged to Metro two sides because it has POW consensus and Turing-complete smart contracts. So the first pair on our exchange will be MTR/ETC.
Further stages: After adoption period we will continue adding other cryptocurrencies.

Airdrop
100,000,000 MTR coins or 10% of the max circulation supply will be distributed to NXT community. For each 10 NXT on your wallet at the moment of the snapshot you'll get 1MTR.
The snapshot was on June 22nd. NXT Snapshot block #: 1894000
Other 100,000,000 MTR coins goes to development team.
Airdrop coins will be locked on the blockchain start. Every mined block will unlock 1/200,000 of locked balances. Thus, about 1000 initial distributed MTR will be unlocked every mined block. The whole initial distributed stake will be unlocked when miners receive 400,000,000 MTR.

looks promising

What would be the cryptocurrencies involved in the trading? Is there gonna be bitcoin and ethereum in it or just NXT? Do you have any plan for other form of airdrop other than having NXT in the wallet? I hope anyone from the dvelopment team could answer this query, thanks.

First currency we plan to add is Ethereum Classic. If the Ethereum will not become pure POS, we will add it right after ETC.

I will elaborate on non-POW pairs prospects later.

 ::) ::) ::) ::) ::)

what is different from the old decentralized decentralization projects that have developed to date, if you know about this project it will be more interesting to consider

There are a lot of successful implementations of DEX. Unfortunately, they limit us to trading either assets issued on the same chain, or promissory notes of tokens on another chain secured by a third party. Our approach allows to safely trade assets from different blockchains. What do I mean by "safely"?
For example, you will be able to trade ETC for ETH without ever trusting your coins to any centralized intermediary, at any step in the process. On old DEX it's impossible, unless it's some form of atomic swap between you and the present owner of ETH, who is desirous of exchanging same amount of ETH back to ETC, which is unlikely at any given moment. In that case DEX would serve as a matching engine between "swappers".

Did you check projects like https://0xproject.com/ and you really expect to surpass them with the team of 2 developers? And did I understand correctly that you are going to give 10% airdrop and 90% tokens left for the team, and there will be no ICO? Who needs your tokens and for what purpose all that time while you will try to complete the 3rd stage in your plan and release Real time trading platform?

Is this like the fork of NXT? Even so, I have no complain. The website looks awesome and the details are very well explained. My only question for now is where are we going to see the MTR? I mean, I know that we should download the NXT Client then buy NXT, but if I am not mistaken, that wallet is for NXT. So.. how are we going to know if we already got the MTR? Where can we see it?

Yes we made a fork of NXT. Clone on github, in terms of source code, and added considerable amout of our own code. As we mention above, we will release wallet in two weeks along with the source code.
We will make a snapshot on NXT block 1894000 and for all accounts give 1 MTR for 10 NXT on Metro blockchain start. We plan this for the first week of July. You just need to use the same pass-phrase in our wallet to get access to airdrop. And your address in our system will be the same except it will start from "MTR-" not "NXT-".
If by fork you mean something similar to Litecoin Private, no, our blockchain starts from a fresh Genesis block and we don't inherit any transactions apart from the state of NXT accounts that go into our Genesis accounts (airdrop).

On a first glance 0xproject uses simple ERC20 token. So it's about promissory notes, if it will involve any tokens outside Ethereum. You'll need to trust token issuer. If someone creates ERC20 for bitcoin tomorrow, would you trust him and send him your BTC to trade on this DEX?
On a second glance, 0xproject looks to be a platform for DApps developers, not the end product for trader/investor.

We will invite more devs when we need them.

No. 10% - airdrop. 10% - team. 80% - miners. No ICO.

You can think about first two stages as of pre-sale phase. Miners will sell what they mine (keeping the tokens they want as an investment) and all who become interested in the project will have opportunity buy tokens, initially on existing NXT d-exchange, then on Metro. During this period everybody will be able to check quality of the team and code, understand basic idea and decide to join project or not.

Hi guys

what are the prospects of adding coins with more exotic consensus to your exchange, like hmm... byteball?
How the peg to NXT will work?

reserved for Chinese

There were questions:
1. What is your token for?
2. Is it a security token, or utility?
3. Will it be traded only on the domestic exchange, or on the external one, too?
4. Exchanges trading NXT will be able to receive, send this token?

korean translation reserved

I am interested in your total supply and the funds allocated for airdrop
I think many will be interested in your airdrop campaign

It looks very good.We look forward this project

For starters we concentrate on POW consensus blockchains, because it's simple to verify them from outside. Every Metro forger can verify work in a POW block from outside, without having the complete data. So just one honest forger is enough for Consensus to establish the truth.
POS systems where depth of chain reorg is limited, like in NXT theoretically also can be added but because the POS attack is worth nothing, bigger percent of stake holders should be checking and verifying POS data supply.
Concerning NXT it is not completely clear whether it will be possible to write a transfer smart contract.
As for Byteball, as we understand it has a primary chain (with side branches merging sooner or later) so data supply can be organized, but we do not know about depth of reorg limit in Byteball DAG.

No promotion giveaway for Vietnamese. Sorry.

This is a good luck for me, the site says that  in order to be eligible for the airdrop, we should have an NXT tokens, and fortuitously i have some in my wallet.
I consider it really lucky for me to hold on those tokens.

1-2. The amount of tokens is the size of stake. (a) Stake gives the right to manage the decentralized corporation. For example stake holder will decide by their votes what crypto would be listed or delisted on the DEX. (b) Stake size determines number of trading order set or cancel without transaction fee. (c) Block producing and in particular data supplying is important and rewarded work. A right to issue POS blocks also is proportional to the forger's stake. (a) and (b) - is utility. We prefer to think that (c) is too, but it's not so obvious.
3. Our wallet API extends NXT one. So it will be quite easy to add our token to any exchange that trade NXT.
4. Exchanges are NXT holders (they keep client's NXT in cold and hot wallets), so they receive airdrop the same way as other holders. Community should ask them, what will they do with Metro tokens they receive.

Total supply: 1,000,000,000
Airdrop: 100,000,000 (10%)

Byteball has smart contracts so all you probably need is Metrodex Blockchain oracle, plus a chatbot (this is one of Byteball's brilliant features). That is kind of centralized, but if it lies, it lies only once (watched by everybody). You can also require some Metro coins deposit from candidates to run such oracle.
NXT seems so feature-rich so it's indeed hard to tell without deep research.
P.S. I am not associated with Byteball, just cyber-squatting this user handle :=)

Hi everybody! Just to remind - the snapshot is planned approximately on June 22nd. Snapshot block number is 1894000. Don't forget to buy NXT if you want to participate in the airdrop! The mainnet will be launched after the snapshot.

Our announcement was posted on nxter.org
https://www.nxter.org/nxter-news-may-2018-iv/#Metrodex

If I buy nxt on bittrex and leave them there for the snapshot, will I still receive metro like I did with ignis. I guess what I’m trying to say is will any exchanges like bittrex support the snapshot like they have with Ardor and ignis?

We do not have any agreements with exchanges. We do not know how they will manage coins they receve. I think you may ask them.

MetroDEX：一个去中心化交易所

总量10亿，NXT持有者10:1获得，暂时锁定，每个区块开采出来解锁500个，当20万区块全部解锁空投1亿和团队开发1亿，NXT高度1894000，预计6月22日到6月23日

1.基于NXT技术和代码建立公链，但是通过POW（挖矿）解决初始化token持有问题

2.使用NXT资产（彩色硬币）交易功能，提供去中心的币之间的转入和转出，近乎实时的交易用户体验

3.向社区提供一个获得各种硬币收入的工具，ETC等



1技术

Metro是混合POS和POW，POW区块：算法（keccak256 ），10分钟一个区块，奖励2000 MTR，每20w个区块，奖励减半（3年10个月），POS区块；区块快照（未来币或阿朵），3秒一个区块，奖励来自手续费（将在第4阶段实施）

2018年09月 - 第二阶段：Transmitting hubs

2018年12月 - 第三阶段：实时交易功能平台

2019年03月 - 第四阶段：与ETC进行对接



1.混合POW / POS区块链实施
我们需要快速模块为用户提供接近实时的交易体验。POS给了我们这样的能力。POW比POS有一个优势 - 不需要额外的数据来检查区块版本的资格，并从区块链外部确定最长的链条。我们需要使用区块链挂钩功能。此外，POS可以防止51％的攻击受到保护。所以，我们需要混合POW/POS。

2.Transmitting hubs
对等网络的规模越大，将块分配给它的时间越长。代理POS区块链显示区块分配的最高速度,代表执行块生产者和块传播枢纽角色。与DPOS不同，我们分割块生成函数和块传播函数。传统上，块产品的功能由矿工和伪造者执行，而传输中心仅负责将其快速传送给所有网络参与者。

3.实时交易平台
我们计划提供一种不逊于中心化交易所的用户体验。

4.与ETC进行对接
以太坊经典将成为第一个与Metro双方对接的加密货币，因为它拥有POW共识和图灵完成的智能合约。所以我们交换中的第一对将是MTR / ETC。

5.其他阶段
将继续添加其他加密货币。

Hi all! I kept some nxt coins in my wallet but how to get airdrop from Metrodex? Nothing changed...

https://bitcointalk.org/index.php?topic=4521336.msg40712566#msg40712566

We are starting a pool at https://mtr.leafpool.com/ It should be available soon...

up please...

As I understand, snapshot has already occurred on the block #1894000.
And when will the MTR tokens send to the NXT wallet? Tokens will be blocked until the miners produce another 200 million MTR? When and what exchanges to wait? Also it is not clear yet what will be the interaction with Ethereum Classic.

Snapshot was made on June 22th, NXT Snapshot block #1894000. Calculated airdrop balances will be available with Metro mainnet start. You just need to use your NXT passphrase when we launch Metro mainnet in first week of July.

Hi there, mainnet launch already ? how about mining phase ?

1) MTR tokens will be given you on Metro blockchain not NXT.
2) Tokens will be unlocked in equal portions each mined block. All initial tokens will be unbloked when the miners produce another 400 million MTR. Miner block reward 2,000.
3) After blockchain start we will trade MTR on NXT blockchain. Then we think about other exchanges.
4) There are a lot of quasi DEX based on bitshares for example. But all cryptocurrency you send on that exchanges stored by their owner. So they can lost or stole them. When we talk about DEX we mean that all cryptocurrencies will be stored also decentralized. We designed Metro that we can not lost or stole deposited cryptocurrencies. We will implement transition smart contracts on each blockchain. Firs blockchains we implement such contracts will be Ethereum and Ethereum Classic.

I do not quite understand when the sales start? At what stage of development is the project now and what are the plans for the near future?

No. Main net start first week of Jully. You may prepare for mining on testnet for now.

1) We have no ICO and pre-sales. You may buy MTR on NXT blockchain exactly after Metro blockchain start.
2) We have implemented stage 1:
and preparing for main net start.
3) See our roadmap. What exactly plans you are interested in?

Mainnet start date is already set: it’s July 6th about 6:30 am UTC. After the mainnet launch we will release the configs for connecting to it, so everybody could start mining.

I was sure that an ASIC was created for this algorithm. But the search for information did not give a positive result. So, this algorithm can still be extracted on the GPU? Or I'm just bad looking) Someone can tell me the exact answer? Thanks)

No ASIC yet.

Wait what? You want us to give you our NXT passphrase to receive airdrop??? LOL sounds scammy

Just moving your NXT balance to others wallet will do. Do be so panicly

1) You can make code review and check that we do not take yor pass. It's quite difficult.
2) Move all your NXT to new account before enter your passphrase in the Metro blockchain. I do such thing for LELE, when they make IGNIS airdrop, for example.

Metro mainnet launch is tomorrow about 6:30 am UTC. We’ll release mainnet wallet on GitHub right after the start.

a project which I think is very helpful buying and selling digital assets in the created by the Metro, I think investors are going to be interested with the project of the Metro because they offer a very unique

Did someone get airdrop?

Link for wallet please... Can not find it on GitHub((

https://github.com/metrosoftware/metrodex/releases

New wallet have updated
https://github.com/metrosoftware/metrodex/releases/download/v0.1.0/metro-client-0.1.1.zip

What a pity, it couldnt run in 32bit structure

The airdrop is interesting, If i don't miss understand the rules, we just have to keep our NXT coin in our wallet isn't it?
Do we have to sent our wallet address that contain NXT coins here in this thread to be able to receive the Metro coin?

No, you just need your NXT passphrase to claim those airdrop.
Let wait further information from dev since this project not start running yet

Anyone got it? Please update....

Hi, I'm trying to run the wallet for testnet but I'm unable to start it because it says that I don't have java installed. I have it, I also reinstalled it because of that but no chance, what can I do?

reserved for HINDI translation..

It seems that on window you need Java exactly 8 version, not 10.

Main net restarted. New wallet released https://github.com/metrosoftware/metrodex/releases/tag/0.2.1

Testnet mining reward has been sent.

I can not use it for MacOS.... Can't understand how to install it... Ohh(

The plan is very interesting and if you really thrive in actualizing your visions, then I think it will be nice.

I wish that the project will satisfy all that has been target!  Good luck all!

38,000 MTR reward already paid.

We have no mac version yet. Sorry.
You may use public node. http://node.metrodex.org

Some time ago hebe-zhang creates blockexplorer for us
http://block.hebeblock.com/#/?type=METRO

what is the atomic exchange system, because in my opinion it is a new exchange system, even though you have found two weaknesses

Our exchange system is new. We take blockstream idea of sidechains and adopt it for exchange. Main weakness of  all DEX based on bitshares that all traded coins stored by third party. So you need to trust them. In our system all traded coins locked in smart contract and no one can spend it even smart contract developers. Stored coins are only unlocked when they are withdrawn.

Miners!
Difficulty is quite low. Take your chance!

Starting test in our pool.
Hard to integrate the algorithm and coin, but we will do =)

Hope so

While we are all awaiting for a major release with pool mining support (we almost sure it will be next week), we make minor release with some database speed increase and block difficulty showing: https://github.com/metrosoftware/metrodex/releases/tag/0.2.2

I am honestly VERY impressed by the development of the wallet and of this coin. Also I am mining it FAST :D

Amazing!

Trying our best!

You wrote. "Metro is a hybrid between Proof-of-Stake based on NXT (Next) and proof of work created in bitcoin with the modified formula of Dark Gravity Wave.". And how do you deal with the anonymity of transactions and what is their speed and cost?

We have shuffling transaction inhertied from NXT. Transaction cost for now (also inherited from NXT) cost 1 MTR.

We apply to this maximum effort.

ATTENTION! Hardfork on key block 4000. Everybody needs to update wallet before this block. We implement stratum compatibility. This will allow us to implement pool. https://github.com/metrosoftware/metrodex/releases/tag/1.12.0

I highly recommend this business to my friends and relatives! They were so much delighted when I told them about it! Devs are working hard and updating us every week on the progress!

Interested in this coin.

Would buy up to 200K at 13 satoshi per token.

We are happy to inform we run pool at http://pool.metrodex.org/ 
Please note that the pool is working in the beta testing mode. So there may be some glitches.
Let's mine!!!

How do you mine this??
My wallet say "cannot determine mining status please define administrator password"?????

Please read mining FAQ:
https://github.com/metrosoftware/metrodex/blob/develop/METRO-MINING_FAQ.pdf

The side chain concept is based on a special intellectual contract that allows you to transfer any underlying network asset to the side chain and back.

Now you can buy Metro on the NXT platform.
Here is trading guide: https://github.com/metrosoftware/metrodex/blob/develop/Metro-NXT-trading-guide.pdf

One caveat:
to place Sell Metro order on NXT, you need to pay 1 NXT. To cancel and place new order, you need another NXT or two.
If you don't have any NXT, read carefully FAQ at the end of the guide, there's a way to buy a few NXT from the asset transfer bot.

Hi guys, I hope you are well.
Did you keep in your code base the multi-phase tx where you specify a hash of the secret, needed in order to redeem?
In that tx, do you need to specify the recipient before secret is presented, or after?

They chose not the best option for buying or selling. For many newcomers like me, this innovation when trading will be very unusual. Hope no one will be angry and everyone will read the instructions before trading.
The most important thing is simplicity and when such strange things are brought to buy it certainly does not add to the popularity of the project.

As I understand, it's just early pre-sale phase. It's mostly for miners, who are quite technically savvy.
When trading starts on Metro platform itself, it'll be much easier. However, the UI will be similar, at least for the first time. Only transactions much faster and cheaper.
At the cost of our SSD space :D

Now we are in contact with two exchanges, and we hope that at least one of them will add our coin in a couple of weeks. Listing takes more time than we think it takes.
When users start to post trading messages in our discord channel we decide that we can help them in two ways. Become guarantee and give them such not very convinirnt exchange as NXT.
When any exchange will list our coin trading on NXT become unnecessary, but before that it's better than nothing.

Yes, sidechains is very powerfull conception!

Hello, what price MTR token this time in usd?

Hmmm, so a coin without a working blockchain! Nice. This coins doesn't even have any active nodes.

Hello! Is it possible to list our ERC20 token on your exchange? Whom can we contact?
