New Bytecoin Release 1.0.8 introduces fusion transactions and wallet outputs optimization

On August 27, we have updated Bytecoin to version 1.0.8. This version includes update of Bytecoin Wallet that enables Fusion Transactions that were announced previously. What's more, the updated Reference Client features a number of optimizations and improvements based on your feedback.

Fusion Transactions provide users with possibility to automatically optimize their accounts. The optimization process runs in background, and it is easy to launch by ticking a single box in the settings.



This optimization will be useful for those users whose Bytecoins are split in multiple small outputs. Such situation might occur if, for example, one receives large numbers of tips to the account or uses pool, which transfers money to the user in multiple small payments (e.g. earlier versions of open source CryptoNote pools). Besides increasing convenience, such optimization will also improve the privacy level of the wallet owner.

Technically, optimization is a fee-free money transaction to yourself such that the number of outputs becomes less while the outputs themselves grow larger. Such a transactions is called Fusion Transaction. If optimization process is on, the wallet will automatically select the outputs that should be fused.

At the moment, only closed beta version of the latest Bytecoin Wallet is available. If you want to participate in account optimization testing, we can provide you with Wallet with Fusion Transaction enabled. To obtain the wallet please contact us, and we will send You the link for download.

In addition to new type of transactions, this update contains other improvements:
1) Instant transactions notification is now available for Wallets connected to remote daemons
2) Reset feature for Bytecoin Wallet to resync your wallet data from the blockchain
3) IWallet High-Level API has been significantly updated
4) JSON RPC interface improvements for Bytecoin Reference Client and RPC Wallet
5) The sync process of Bytecoin Wallet on OS X has been improved.

The latest Bytecoin Reference Client and RPC Wallet version can be found on our website. To obtain beta version of Bytecoin Wallet, please contact us.

Bytecoin 1.0.7 have been released.

Bytecoin 1.0.6.1 released.

Bytecoin 1.0.6 updates CryptoNote and upgrades e-commerce integration

Today's release introduces an updated Bytecoin RPC Wallet for e-commerce with a new feature called aggregate multi-addresses. In short, this feature allows services to create a branch of unique addresses to easily differentiate users. This feature is a significant update of the CryptoNote protocol:

• It effectively depreciates payment_id (a formerly indispensable part for any CryptoNote currency)
• It facilitates web wallets operation
• It greatly upgrades Bytecoin integration and deposits by allowing to assign each user with a unique address
• It reduces server resources required for maintaining dozens of users' addresses
• It increases overall privacy of Bytecoin

There is more to 1.0.6 release than just aggregate multi-addresses feature:

• Updated IWallet and IBlockchainExplorer high level APIs
• Traffic between the node and the wallet has been optimized providing faster synchronization

Towards easier integration

Now all you have to do to integrate Bytecoin is:

1. Install Bytecoin RPC Wallet
2. Generate users addresses for each new user (through Bytecoin RPC Wallet API)
3. Process the payments in a matter of seconds

Important note: updating your Bytecoin RPC Wallet service will not disrupt your currently established system. This update is entirely backward compatible with payment_id deposits even though payment_id will be depreciated in further releases.


Update explained

The core idea of aggregate multi-addresses can be described as 'shared half of view key', i.e. common data for all users, namely key 'a'. Keys 'b', surely, are unique for each user, which implies different 'spend keys' and different addresses.



We've explained the adjustments in CryptoNote which made this update available in our blog post on aggregate multi-addresses.

Hey! Many thanks!

I have updated my gui on one windows machine - looking very good.

Got my bytecoind running on another Win8.1 x64 machine; Didn't have to reindex, just had to delete p2pstate, poolstate and then good to go - I was using a really old one there!

However the simplewallet loads up my wallet just fine.

Thanks for your ongoing hard work!  

We have just updated Bytecoin to version 1.0.5. The following features have been introduced:

Bytecoin Reference Client

1. Real-time transactions pool synchronization is a solution, which guarantees that all network nodes have similar unconfirmed transactions lists. As soon as one node receives user's transaction, it ensures that this transaction is included into transactions pools of all nodes. Therefore, every miner will have a complete unconfirmed transactions list. Read more in our blog post that covers the solution.

2. New network library with network code operating significantly faster than the existing solution. It allows for increased stability of data exchange between the nodes in runtime. We are planning to release this library as a stand-alone project so that any p2p app developer can use utilize it.

3. Block Explorer high-level API has been added to our APIs. With its help, developers will be able to create services that obtain data directly from the blockchain. We've used this interface to integrate Block Explorer into the Wallet. Read more in Bytecoin Wiki

4. A new method "list_transfers" has been introduced in Bytcoin RPC Wallet allowing to receive all incoming transactions regardless of their payment_id.


Bytecoin Wallet

5. In-wallet integrated miner and block explorer. These features turn Wallet into an integral 'control center' allowing to receive and send transactions, mine BCN using any pool, and navigate inside in-app block explorer.

Bytecoin Roadmap
Bytecoin Wiki

Bytecoin team has updated the roadmap for the upcoming three releases:

- Version 1.0.6 has been split. Real time transactions sync has been moved earlier to version 1.0.5, which is coming out this week. Other features (tracking key import/export and 8-bit color scheme) have been moved to version 1.0.7
- Multiple addressing for Bytecoin RPC Wallet has been moved to version 1.0.6 (instead of 1.0.7).
- Version 1.0.7 introduces two significant CryptoNote protocol updates: new transaction priority rules and transactions inputs optimization:

Today, on 27 of May, the Bytecoin team has updated Bytecoin to version 1.0.4. The main part of the update is the Bytecoin RPC Wallet that substantially improves operation of third party applications and services in the Bytecoin network via RPC.

Thanks to RPC Wallet the merchandisers can easily connect their shops to the Bytecoin network and start automatically accepting payments. This service will also boost performance and simplify connecting exchanges and other third party services.

Main features of Bytecoin RPC Wallet:

• Much attention has been paid to Wallet efficiency. Bytecoin RPC Wallet requires small amount of RAM for operation.
• Being cross-platform, RPC Wallet can run as a daemon (Linux/OS X) and as a service (Windows).
• RPC Wallet is capable of processing 3 times the amount of transactions per second (tps) compared to our previous solution, the RPC Simplewallet. The total amount of tps is now 60.
• RPC Wallet supports approximately 10,000 remote connections. It greatly simplifies connection management for 3rd party applications.
• Bytecoin RPC Wallet provides you high-level security. It is impossible to get access to Wallet’s private keys via RPC.
• Developer-friendly and minimalistic interface allows for flexible setting any required functions via RPC-requests.
• RPC Wallet can start up an internal node of the network, or it can use external node in case you need to save resources.

The Bytecoin RPC Wallet is more flexible and functional than Simplewallet RPC interface, superceding it. Therefore, Simplewallet RPC interface will be deprecated later on.

The Bytecoin release 1.0.4 contains refactored and optimized daemon. It enhances code modularity and allows us to tremendously increase software test coverage. The team has introduced a new multi-threading library that makes daemon behavior more predictable. It will be released as a stand-alone project later on. Moreover, we have improved console logging.

GUI Wallet has also been updated. Now it supports selection of color themes. It is also capable of flexible connection to remote daemon or start an in-process node.

Bytecoin RPC Wallet can be built from the sources or downloaded here.

Please feel free to discuss it here.

Bytecoin Wallet, the elegant GUI wallet, has been released. More information in this thread: https://bitcointalksearch.org/topic/bytecoin-wallet-gui-1018904

Now that opens up a can of worms! I've been watching the gold market for some time: I've seen gold leap up or down, after a Fed announcement was released, in a matter of microseconds. HFT tradebots do that for ya.

Conventional markets move so fast, there's no way that any trustless peg could be implemented: network latency would kill it. That's why BitShares' bytemaster settled upon the median of the prices broadcast by all the delegate nodes. 

The only other way would be to accept a value within a specified range, but that opens up a catch-22. The narrower (closer to precise) the range, the more often that ordinary volatility + HFT + network latency will cause the auditor bots to reject a valid value. The wider (farther away from precise) the range, the greater scope there is to run a long con that "takes a clip from the coin."

I'm only guessing here, but I think that bytemaster first thought of a range but rejected it when he saw that catch-22.

huh, cool just-in-time releases

What kind of implementation of trustless peg (especially for gold and fiat) do you mean?
We're going to provide a technology letting other parties emit various types of currencies. We're not going to emit a bitUSD analog oursleves, but we should not prohibit creating one in theory. Do you think we need to?

As for the company shares, we do share your vision. In this case its company trust that we're talking about, so no need to have it backed by an underlying asset.

Bytecoin Reference Client v.1.0.3 released.
Bytecoin GUI Wallet is coming out later this week.
Bytecoin Wiki has been largely updated.

In the meantime you may check out our Bytecoin: Under the Hood post where I explain our technology vision and give overview of what has been achieved so far.

Great updates are coming to Bytecoin.

BTW: any news about early-april 2015 release dates?

the important part of my post is: but please dont try some semi-working-method to tie it to anything

i see two different kind of assets:
1) other currencies like usd or commodities like gold. in this case i'd prefer a trustless peg (if possible at all - not seen until now)
2) share in a company: in this case you have to trust someone (eg the company itself). so i dont think there is a need for a trustless peg.

if someone figures out a way to back an asset which resides on the blockchain (in a trustless way) i'd certainly use it

afaik 2 is planned and i am fully ok with it (even bitcoin itself can handle them by using colored coins). number one is the interesting and complex one

What you describe here is just one use case of assets. We pursue the vision that Bytecoin assets can be backed by the underlying asset, or may not be. Digital assets also largely increase the power of smart contracts as they can represent basically any digital token.

please dont copy bitusd!
who needs an asser which in case of a black-swan event starts a death-spiral which fires itself?
(if bitshares loose moren than 50% of its value bitusd gets forced liquidated and transformed back to bitshares - what do you think will people do in this case? they have proofed (by holding bitusd) that they want usd: they will convert their "new" bts back to usd: which means bts will loose more value again...

^no thanks

assets in itself are a good idea: but please dont try some semi-working-method to tie it to anything.

The next Bytecoin release (1.0.3) is coming out early next week. Follow Bytecoin website and blog for more info.
