Kabo 2020 retrospective

It was a tough year, as, probably, for many of us, we lost several exchanges (though it wasn’t our fault) and our devs had less time for volunteer work on this project for obvious reasons, but at least the Karbo network itself works fine and without any issues.

There were no loud, groundbreaking and exciting achievements, we did a lot of steady development, research and improvements of Karbo here and there instead. To mention the few:

A so-called Karbo 2 with a database-driven backend for blockchain storage has been working fine throughout this year and is now recommended to use. Moreover, if everything goes fine, it will replace the current Karbo 1 version in the (near) future.
Lite blocks were added that reduce bandwidth usage of Karbo nodes.
A lot of P2P improvements to reduce bandwidth usage and improve Karbo network security.
Poor man's Dandelion protocol to improve users' privacy and anonymity.
Deterministic transaction keys that allow proof of payment even after the reset of the wallet.
Added SSL support for both RPC requests and wallets which allows better integration of Karbo nodes into browser-based apps and websites as well as further improves user’s security.
Our browser-based “web-wallet” has got a huge boost of sync speed and now can be comfortably used as an alternative for a desktop or native mobile wallet.
We hope you like the new dark design of our native wallet that was introduced this year.

We are studying possible ways of development of the current POW scheme securing the Karbo blockchain. Several POW algorithms were tested; a multi-algo approach was developed, implemented and tested; the Proof of Work with Stake underwent a lot of changes and development; all these together with BLODHA resulting in a new interesting perspective of the possible future of Karbo mining, namely Proof of Work with Cold Stake. We do not want to make firm statements, time will tell, but this variant that we came to so far looks promising. Stay tuned.

So far it is mined on CryptoNote ASICs. Coinbase in its blog post states "The only way a proof-of-work coin can materially reduce the risk from 51% attacks is to be the dominant application of the hardware used to mine the asset. A coin mined on widely available general purpose hardware, such as CPUs and GPUs, lacks this major security feature." Merely changing POW algorithm will not improve the security of the Karbo network. On the contrary, this can potentially do more harm than good, if we take into account that there are no many coins left for mining with existing CryptoNight ASICs. So, for the time being, we trade indulging of home miners and potential issues coming with ASICs for better security.

Congratulations!
I like this exchange, I'm using it from time to time

What about mining Karbo these days?
Is it ASIC-resistance or some people mine with ASICs?

Karbo 2 CLI and GUI wallets got a successive update with a fix of sync problems at some conditions. Also, all GUI wallets for macOS were fixed, now work again on older versions of macOS 10.12.

Download from https://karbo.io/download/ (links direct to respective Github repositories).

The CryptoNote algo is now ASIC-mineable, and we didn't see the point in the cat-and-mouse chase game and didn't change algo, therefore mining tab was removed from wallets as it became pointless. We are not going to indulge newbies who want to play around with mining some coins with little effort sacrificing security to some questionable adoption. Even if we change mining it will be something that guarantees security as we see it. And it will involve investments as the only thing providing security in POW, and at the moment ASICs provide security because this is an investment with little range of mineable coins and no easy rental for attacks. So, no one button click to mine anymore, even if there will be such a button in the wallet, it will require also a stake of coins and/or hardware in flexible proportions.

Thanks for explanation, reasonable arguments

Hi, even if we change POW it won't be easily mineable for newbies in a sense of the flood of easy coins, it will require serious investments in any case, either in hardware or in coin itself.

I remember maybe 2-3 years ago the previous version of wallet had this option (you could choose pool or even do solo mining)
Somebody told me in another thread that there will be new version which will have this feature again

Are you thinking to change POW? To POS? Or just some anti-ASIC measure?

Hi,

Any info when the new Karbo wallet version will have mining from wallet? (Heard about in another thread)

I need it, because I know some people who want to mine crypto. They are new to the area and that's one of the best options for them)

GUI wallets and CLI suite were updated again. Download from https://karbo.io/download/ or Github repos. We remind mining pools to update (not strictly need to update from v. 1.7.3 to v. 1.7.4 if you updated recently as the difference between v.1.7.3 and 1.7.4 is in the encoding of signatures of messages which are not widely used).

We recommend exchanges and other services to update to the latest version because of a miners enforced soft work at height 500000 which is nearing.

HAPPY BIRTHDAY!!!    KARBO - 4 years!!!

First block 4 years ago - https://explorer.karbo.io/?hash=93fd06c51fd8a6fc9db100adbdb4c1de11270a5186b790b454db8a7419c5615e#block



For this past year Karbo became faster and leaner.

Karbo Classic wallet became more beautiful (dark theme designed - https://twitter.com/krbcoin/status/1220702250869411840).

An alternative CLI Suite and accompanying GUI Wallet developed.

Karbo blockexplorer significantly updated and improved (new design + new features) - https://explorer.karbo.io.

Karbo Lite Wallet updated - https://github.com/Karbovanets/Karbo-lite/releases/tag/v.1.0.9

Improved and updated service for replenishing a mobile communication account by KRB (140 countries, 600 mobile operators) - https://karbo.top

Karbo coin (KRB) was listed to trading on three new cryptocurrency exchanges.




These are just changes listed in releases which just vaguely hint real amount of work and devotion put into this project:

- Boost synchronization speed. (It nows syncs in 15-20 minutes to the latest checkpoint. If you want to sync even faster, take the most recent block's height and hash and feed it to daemon as a checkpoint with --load-checkpoints flag) - https://github.com/seredat/karbowanecwallet/releases/tag/v.1.3.7
- Redesign and optimization of Karbo Classic GUI Wallet - https://github.com/seredat/karbowanecwallet/releases/tag/v.1.4.0
- Poor man's Dandelion protocol implemented to increase anonymity at the network level - https://github.com/seredat/karbowanecwallet/releases/tag/v.1.4.1
- Fixed fee validation bug
- Fixed various compiler warnings, typos and minor errors
- Optimizer tool for walletd
- Optimized transaction fee check
- Optimized crypto, RPC, CMake scripts, fix various minor bugs and compiler warnings
- Spend Key Images now stored with blockchain height allowing to check proof of balance against given height
- Code cleanup: removed various unused files and functions, fixed some bugs
- Changes in RPC: removed some deprecated methods, renamed some fields (many that should've been changed too were left intact for backward compatibility with wallets), allowed some methods while node is syncing
- Check locked amounts in reserve proof RPC method
- Start scan height option for restoring wallets
- Functions used in GUI to lock wallet and to confirm sensitive operations by password
- Daemon save command to store blockchain cache to disk
- RPC method for walletd to show addresses count
- Lite blocks propagation, this should reduce traffic between nodes
- Attempt to restore corrupted blockindexes.dat
- Platform independent randomness
- Improvements in simplewallet
- Node update with new endpoints, including info about connections for display in GUI Wallet
- Fix of fee check in Core, fixes syncing from zero with the flag --without-checkpoints
- Ban nodes that stuck too deep behind on fork to spare useless traffic
- Changes in P2P:
Moved P2P protocol version to common config
Added warning about outdated software
Added dropping the connection to outdated too much nodes
Added anchor connections, based on https://eprint.iacr.org/2015/263.pdf §4
- Change how we deal with unmixable outputs in wallet:
if transaction is zero mixin, first take all unmixable outputs to send, then normal outputs for transactions with mixin first, take normal outputs, only if not enough take dust, unmixable outputs, obviously, not used for sending, sweep_dust command is removed from simplewallet, the warning is displayed when the user has unmixable outputs that he can get rid of them by sending tx with zero mixin, in the edge case of so many unmixable outputs that it will make tx invalid due to exceeding tx size limit user will have to send them in chunks (at cost of an extra fee, but old behaviour is the same)
- Add tools to get some useful statistics via RPC e.g. for building historical charts
- Change spent key images storage (reduce memory usage)
- Deterministic transaction keys
- Fixed missing address file name when import tracking wallet
- Fixed validation on atypical to domains
- Flat-rate fee for public nodes
- Proper Base58 encoding of proofs
- Small optimization in pushBlock: do not recalculate block hash
- Tidyup crypto: make crypto primitives more clear, move scattered and repeated definitions to one place, add some new crypto functions, fix compiler warning
- --enable-blockchain-indexes now has a short alias -i
- Change storage for various blockchain indexes
- Transaction fees per byte for extra data
- Exposed these RESTful-like API endpoints for GET requests:
/api/block/height/[height] - returns block info in JSON by height
/api/block/hash/[hash] - returns block info in JSON by hash
/api/transaction/[hash] - returns transaction info in JSON by hash
/api/payment_id/[hash] - returns the list of transaction hashes by payment id in JSON
- Changes in node server
- Added nice HTML output to / path with basic stats
- Added plain HTML /supply endpoint that returns a string with total coins in circulation
- Moved /paimentid endpoint to the plain HTML output of randomly generated payment id instead of JSON

Finally released alternative clients implementation with database blockchain storage. Although they sync a bit slower (40min vs 20min) but use much less RAM - merely 100Mb vs 1.5Gb, blockchain size 6.7Gb on new vs 4.4Gb on old.

CLI: https://github.com/Karbovanets/karbo/releases/tag/v.2.3.0

GUI: https://github.com/Karbovanets/karbowanecwallet/releases/tag/v.2.1.0

If everything goes fine, we'll eventually migrate to these versions.
