He is indeed.

Since James commented on this i presume this is genuine?
Is it possible that Rob is the developer of Biblepay?

Greetz, djoser.

That was a very graceful letter from Rob, and merely formalizes what has been operationally true for some time.

From @barton26's writeup on Reddit...

The Gridcoin Developers are proud to unveil our latest milestone release, version 4.0.2, codename Camilla. This release contains a lot of small fixes and optimizations as well as the long awaited side staking and stake splitting functionality! This is a leisure release, and not required for users. It is however recommended if you want the latest features and optimizations!

For some of the details about the syncing optimizations, please see https://steemit.com/gridcoin/@ravonn/a-disappointing-optimization from core developer @ravonn. Overall users can expect a roughly 10-25% improvement in speeds when syncing the wallet. As always we continue to look for new ways to decrease sync time and reduce our need for snapshots.

Probably the biggest and most exciting part of this milestone is the addition of Stake Splitting and Side Staking added by @jamescowens. He describes how to use the feature in his PR:

This PR extends the work I have done in PR #1244 and implements the ability to "side stake" or distribute the CBR and research rewards to valid addresses. These addresses may be in the same wallet or any other valid Gridcoin address. The potential uses for sidestaking range from a person insuring that all reward go into the same address (and key) for easier backup and recovery to someone donating CBR and rewards to a charity, or sending it to their grandma! . This functionality is very similar to Pinkcoin.

The PR adds the following additional conf file parameters...

enablesidestaking=0|1 sidestake=address,allocation_percentage

You can specify multiple sidetake entries, just like addnode or connect. Note that the total number of ouputs for the coinstake will be limited to 8 in V10, and vout[0] must be empty, so that gives 7 usable outputs. One must always be reserved for the actual coinstake output (return), so that leaves up to 6 usuable outputs for rewards distribution.

Note that the total of all of the percentages can add up to less than 100%, in which cases the leftover reward will be returned back on the coinstake(s).

Also with side staking we have stake splitting, which enables users to optimize their UTXOs automatically when they stake. Jim describes how it works in this PR:

This PR implements three conf file parameters:

minstakesplitvalue enablestakesplit stakingefficiency

enablestakesplit=1 will enable the automatic splitting of UTXO's in the coinstake transaction (stake outputs). Zero is the default (disabled).

stakingefficiency=xx is an integer that specifies the desired staking efficiency. This is constrained by the code to be between 75% and 98%

minstakesplitvalue=xxx is an integer that specifies the minimum UTXO size desired post split to provide a secondary control on UTXO size. If difficulty drops and a high efficiency is specified, the efficiency alone may split UTXO's into amounts smaller than the user desires. This will prevent that from occurring. If a user specifies less than 800 GRC, then the code uses 800 GRC. Note that the stake splitter uses a 160 block averaging interval for calculating the difficulty to smooth out the difficulty swings.

So to summarize, users can enable side staking in their wallets by adding the line enablesidestaking=1 to their config files. To add addresses to side stake to, simply add another line for each side stake entry like so sidestake=address,percentage.

To enable stake splitting in your wallet, add the line enablestakesplit=1 to your config. This will enable default splitting at 90% efficiency. To change the efficiency value, simply add another line with stakingefficiency=xx where "xx" is a percentage (between 75 and 98).

Note that there is already development work underway to allow users to define their side staking or splitting preferences from within the wallet. Currently the functionality is enabled through config flags only. Note that changing your config will require a wallet restart to use the new settings!

I am pleased to announce that the native C++ replacement for the "neural network" has been merged into the development branch and is slated for the Denise milestone release.

you're right

i should have done some research before posting

Anyway, i put here the link for some other users --> https://www.gridcoin.us/Guides/investor-gridcoin-setup.htm

maybe you will be surprised - gridcoin dot us

Hello everyone, i would like to start to mine gridcoin as i am a boinc's user since 2011.

Where can i find some guide about it?

Thanks!

Reward mechanisms and network security in Proof of Stake: The case of Gridcoin
https://steemit.com/gridcoin/@sensi-stats/reward-mechanisms-and-network-security-in-proof-of-stake-the-case-of-gridcoin

Hello Jim,

thank you very much for posting here! It's been a long time since a developer posted something here.
The upcoming features sound awesome and i'm looking forward to them.
Thanks for still working with such enthusiasm on this great coin!

Yours sincerely,
djoser.

Here are some comments...

The last mandatory implemented Constant Block Rewards, which is POS of 10 GRC per block staked. Proof of Research is paid on top based on calculated magnitude. This implements linear inflation, which means the percentage of inflation will slowly decline. It also does away with paying time based interest, which encourages people to keep their nodes online to stake and secure the network. It has worked and we have seen difficulty rise from an average of < 3 to almost 9, meaning triple the number of coins are online. This is really good for network security.

The 4.0.1.0 leisure corrected a longstanding and subtle bug in the calculation of lifetime research rewards that was causing chain forks. This was the last "big one" that was causing forks. The chain has been extraordinarily stable since then.

The Camilla milestone has automatic UTXO splitting on the coinstake output to optimize staking in the CBR regime, and also sidestaking, which provides the ability to direct your reward to up to six different valid addresses (specifying a percentage for each). This makes the ability to conveniently create a "cold" wallet to receive the rewards possible.

Camilla also fixes a number of bugs and implements a number of performance optimizations.

Denise has a number of really cool enhancements coming along...

I have completely rewritten the BOINC statistics collection and computation code (the scraper and "neural network") in native C++, completely integrated in the core wallet code. This will completely replace the old .net VB code and make the stats computation and NN completely cross platform, and 10X more efficient.

We are going to be completely overhauling the UI... see

In the future, manual (user initiated rewards claims) and more.

Lots of activity on this coin and a good core team. Ravon is the technical lead.

What’s coming in 2019? Glad this coin has survived the altcoin cull! Although I knew it would thanks to the amazing unique properties.

one old coin and still alive to date,this one coin is very potential guys..
see current prices are very under value https://ibb.co/PmBSqZT
I saw last year no big pump happened..


good luck

Well, it is my great pleasure to inform you that Gridcoin’s New Marketing Initiative has received plenty of support and that it’s officially going LIVE, as of today! It will take some time to ramp everything up and there’s a lot of work ahead for sure, but if you go to Google now and search for BOINC (or something BOINC-related), you should get a nice ad like this, pointing to our website gridcoin 

Gridcoin Leisure Update 4.0.1 Released
The Gridcoin development team is happy to announce a hotfix release to the previous 4.0.0 mandatory that fixes the root cause of the bad forks we have experienced recently. This hotfix also contains a minor patch to the voting system that fixes a bug discovered while testing.

Yes, if you stake GRC in your wallet why not?
I got recently 9..something GRC - may be for this new staking.

Also I need to say that I like new wallet version much more!
