General Discussion / Qora and Ether added to metaexchange coin voting page

« on: July 29, 2015, 07:23:49 am »

Due to popular demand I've added qora and ether to our coin voting page here: https://metaexchange.info/voting

qora: 15VVA7g7i89jHyrunWniiALQnx1gRzBw7H
ether: 1DsYUvRrgMELdPXC7zPEiuPd7fss83QzDN

Votes cost 0.001 BTC each, and each one goes towards a 20 BTC float for the market maker - having a coin voted in at metaexchange means having a permanent whale in the market at all times, providing liquidity while only breaking even.

Cheers, Paul.

General Discussion / Could bitshares completely eliminate forks, and therefore double spends?

« on: July 24, 2015, 02:59:59 pm »

I make the following assumptions:

* Forks are the only thing which make a double spend attack possible

* A forkless blockchain has no need for an amortised consensus

A forkless blockchain is only possible where all nodes are aware of who the block producers are, because otherwise you could have islands of nodes with separate consensus from the main group with their own block producers. If a node finds itself cut off from all the block producers, it must wait to reconnect - consensus stalls for such a node.

Network latency can cause forks in an amortised consensus because the set of candidate transactions can be different between block producers at block production time. However, if consensus happens simultaneously, picking the majority common transaction set between block producers would eliminate the problem with latency - all delegates come to an agreement about their common transactions, which get put into a block, and the remaining transactions are simply postponed.

Under this model, there is no possibility for a fork to form, either consensus continues to progress, or it stalls completely. With no forks, there can be no double spends and transactions can be accepted with confidence as soon as they enter a block.

Thoughts?

General Discussion / [Bounty] 160,000 BTS for an instant exchange arbitrage bot

« on: July 18, 2015, 09:19:36 pm »

I don't have time to code this myself, so I'm gonna make a ~~40k~~ ~~80k~~ 160k BTS bounty for a metaexchange->shapeshift->blocktrades arbitrage bot.

It should automatically work out if there is a profit to be made through arbitrage between each of the instant exchanges and then actually be able to make the trade (by sending funds from the relevant wallet) and record the actual results (by monitoring wallets and exchanges) along with the expected result in a mysql database.

Blocktrades.io doesn't have an official API, so the author will need to use cunning to get this to work

edit: oh, and this should be made open source as well, github

General Discussion / Metaexchange coin voting thread

« on: July 17, 2015, 10:16:33 am »

If you'd like to see a particular coin/asset added to metaexchange, and it's not already on our voting list, please mention it here.

For our current list of coins to vote on, see our voting page: https://metaexchange.info/voting

Technical Support / Will 2.0 have a client, or is it a website?

« on: June 17, 2015, 03:59:42 pm »

I know they're targeting an online wallet first, but does that mean the initial release will lack a client?

What about RPC calls?

Technical Support / Why have bitAssets been renamed to SmartCoins in 2.0?!

« on: June 16, 2015, 09:30:00 am »

Renaming bitAssets to SmartCoins would be great if you were creating a completely separate and competing blockchain to bitshares, but not if you are planning to 'upgrade' the chain.

By changing the name, you cause confusion and make the history of the technology even more muddy, IMO.

General Discussion / [ANN] Metaexchange adds Relative Orders!

« on: June 16, 2015, 08:24:10 am »

Hi everyone,

We're pleased to announce that Relative Orders have been added to metaexchange markets BTS/BTC and bitBTC/BTC!

Relative orders are limit orders which automatically track the mid-price of the market. They re-price themselves after every single trade and allow market makers to save on the maintenance costs of replacing their orders to track the market. Relative orders cost nothing for the user.

How to use:

Once you've chosen 'Relative' mode, you specify the percentage of the mid-price you'd like your order to track in the 'price' field (from 1% to 255%). Then place your order as normal and they will automatically re-price after every trade.

We'd love to know what you think!

Technical Support / Why has bitGold got a negative yield on bitsharesblocks.com?

« on: June 14, 2015, 04:40:18 pm »

Just a calculation bug?

Technical Support / Would a trustless bitshares have 51 block confirmation times?

« on: June 12, 2015, 08:51:32 am »

With good network health, we have confirmed transactions at 1 block and I remember reading something by bytemaster on why this was ok (it was related to forking and probability), but if you think about it, 1 block is 1/101 of the network signing off on your transaction.

After 51 blocks, 50% of the network signs off on your transaction, which appears at first glance to be the amount of time you'd want to wait in a trustless system - so if bitshares were trustless, would we be waiting 51 blocks for a confirmation?

Technical Support / What if 51 delegates do not move over to Bitshares 2.0?

« on: June 11, 2015, 08:49:04 am »

As I understand it, Bitshares 2.0 is a new blockchain, with new private keys for everyone. So, what happens if 51 delegates decide to keep the old blockchain running?

Or, what if all the current delegates move over, but 51 new delegates fall into place on the old chain?

Technical Support / [Account maintenance costs]

Can someone break this down?

General Discussion / bitUSD / USD.bitstamp or USD.snapswap-us on metaexchange?

« on: June 05, 2015, 04:12:32 pm »

Hi guys,

Just want to see if there is any interest in candidate new metaexchanges markets:

* bitUSD / USD.bitstamp
* bitUSD / USD.snapswap-us
* NASDAQC / BTC
* NIKKEI / BTC

The first two would be done as ripple assets trading against bitUSD, the last two would be based on the new feeds the delegates are setting up.

It's easy to say, yes, great - lets do all of them, but we have to pick the most popular one first because we need to raise funds for the market maker for each of these markets, which costs about 10 BTC per market, minimum.

I'm considering adding a market voting feature to metaexchange, to allow users to vote with their wallets for each new market. Would something like that be acceptable to you guys?

I'd love to get your feedback on this

Oh, and feel free to suggest any other markets you'd like to see if those are not to your tastes!

Cheers, Paul.

General Discussion / Someone creates bogus transaction for trillians of ether on test network

« on: June 03, 2015, 08:17:50 pm »

I guess they still have a long way to go until they can safely release if they're still finding bugs like this...

General Discussion / [ANN] Limit orders added to Metaexchange - world first!

« on: June 03, 2015, 11:56:37 am »

Hi everyone,

Metaexchange has become the first ever exchange to allow it's users to place cross-blockchain limit orders without registration!

What this means is that anyone with the relevant wallets can simply go to our site, enter their receiving address, price and expiry time, send a transaction and have it rest on our orderbook until it either gets filled, or expires! No need to register, no need to log in / log out, the process is totally frictionless.

We're opening this feature up on our first two markets, BTS/BTC and bitBTC/BTC, with more markets to come in the future.

New features for BTS/BTC and bitBTC/BTC markets:

*) You can now place limit orders on our using the same registration free process you're used to
*) Set your own refund address for buy orders to avoid the problem where funds are automatically refunded to an exchange's wallet in case of failure
*) Soft refund policy - orders are filled as much as possible and only the remainder is refunded instead of the entire order
*) More liquidity is available in both markets for larger orders
*) Get a quote (using the input boxes at the top) for any given order size before you place your order
*) See our full orderbooks (using Expert mode)
*) Your browser will now save your bitshares/bitcoin and refund addresses so you don't need to type them in each time

Here is a screenshot:

Needless to say this was a big undertaking, which is why there hasn't been an update from me in a while. Nevertheless, we would love to hear your feedback about the new metaexchange, so please let us know what you think!

Cheers, Paul.
