It's a super old handle. At one point in my life I made biodiesel (methyl alkyl esters) from waste vegetable oil sources, yes.

thanks so much, greatly appreciated!

The algo will be disclosed at launch (CPU only, so this secrecy helps avoid gpuminers jumping in too soon). The launch is Saturday, February 21st at 8 PM Pacific Time (US).

Lightsplasher: the CPU algo being used will be disclosed at launch.

We have an official ANN thread going for the new launch:

Official Notice: Important Updates

Background: The GreenCoin Foundation operates its environmental imperative by maintaining a coin (GreenCoin) that had been specifically developed to provide exactly 50% of the coins generated in a newly mined block directly to an address controlled by the Foundation (which are mathematically divided and sent to renewable producers for their relative carbon mitigated useful work). In early December it was observed that the GreenCoin Foundation was not receiving exactly 50% of the coins, as was supposed to be the case per the Foundation specification. It was further determined that one of the pools had been able to defeat the coinbase transaction requirement that 1,000 coins be sent to the Foundation address. The issue was discussed in great detail in this post. Over the course of the last couple of months the Foundation received ca. 500,000 on average per day (as opposed to the ~1,400,00 it was supposed to receive). In order to preserve the integrity of the coin the Foundation purchased the ~900,000 coins necessary to bring the payout balance up to 50% of the total mined balance each day (~36M coins total).

During this time the Foundation also solicited for an individual to develop a solution to the issue. We have since found such a technical lead who has presented a solution that involves releasing a new coin. We are pre-announcing the release so users can ask questions, raise concerns and provide feedback.

Proposed Solution: The Foundation will cease to support the current GreenCoin release. We are releasing a new coin and will only support the new coin going forward. Holders of the old coin will be able to exchange their coins for the new coin for a reasonable, yet limited, amount of time.

Name: GreenCoinX
Symbol: GREX

Release Date: Saturday, February 21, 2015: 8 PM Pacific Standard Time (US).

High Level Overview:
- 100,000,000 (100 million) total coins. The old coin had too many coins which inhibited adoption for a number of reasons.
- A PoW/PoS hybrid, CPU-only mineable coin that significantly reduces power consumption (more green)
- PoS Interest: begins at 100%, gently curves downward depending on number of adopted users. Similar to Novacoin's implementation.
- Updated coin production deflation curve that more closely matches the intended carbon mitigation effect of the coins future use and trajectory (see sch. below)
- An upgraded, less buggy wallet
- Producers will receive new coins (GREX) for their production beginning Sunday Feb. 22.

Wallet Features:
- No IRC (Faster)
- Very Fast Wallet Start (Qt)
- Automatic Sending of Mature Coins to Savings Address
- Built in Block Explorer
- Detailed POW/POS Info

Coin Specs:
1.   Coin Specs - POW/POS
2.   Algorithm: Mirror - Secure, fast and efficient - 100 x Scrypt speeds - CPU Only at launch
3.   Total coins: 100,000,000 (one hundred million)
4.   Block Time: 60 seconds target (approximately)
5.   Initial coins per block:
6.   Coins per block awarded to miners: Stars at 3.7 (50%)
7.   Coins per block awarded to Foundation: Starts at 3.7(50%)
8.   Halving rate: Gradually decreases from 3.8 to 0 over 40 years - decrease by ~0.1 every year
9.   Difficulty Retarget: Every 2 Blocks
10.   Confirmations on Transactions: 5 (about  5 minutes)
11.   Confirmations on Mined Blocks: 25 (about  25 Minutes)
12.   Ports: P2P 7554, RPC 7553

Exchanging old coins:
In the release, there will be 6M pre-mined coins to be held by the Foundation and to be used exclusively for exchanging new coins for old coins. This represents 6% of all of the new coins that can ever be mined (note that when we devised the solution we were near block 300,000 = 600M old coins which is why this number was chosen). In order to allow for timely exchanging, but not support both coins overlapping for too long, we will allow old coins to be exchanged for new coins until block 500,000 of the old coin is reached. At this time there will be 1B total old coins outstanding. Therefore old coins will be exchanged for new coins at a rate of 166.6666667 GRE to 1.00000000 GREX.

We are currently on block ~346,000 for the old coin, and the coin generates about 1,400 blocks per day. Stipulating this rate continues about the same, that will yield over 100 days (or until ~ June 2nd, 2015) for everyone to be able to exchange their old coins for new coins. The Foundation will operate this exchange (and manually so, if need be). We will accept the coins to a central address to be determined. Once a confirmed transaction is received and a new coin (GREX) address supplied, the requisite new coins will be issued to the sender. The old coins will either be sent to a burned address or held in a wallet that we encrypt with an unmemorable password and then destroy the password. We will not utilize the old coin in any way and we will no longer support it.

As always, my goal first and foremost is to be make sure users are being treated as fairly as possible. We welcome feedback and also ask for any assistance that may help the transition be a smooth one. Once this "coin plumbing" issue is behind us, all of the previous discussions around marketing, growth, faucets, and everything else is back on the table, and we plan to begin executing on them very quickly after the release. We are excited by this transition and feel it is in the best interest of the stakeholders and for the global environmental imperative we are attempting to effectuate and to serve.

I will keep updating throughout the week on the location for the code, wallets, and more specific details for the launch.

Coin mining schedule:






 

We will be fixing this very soon.

I haven't staked since 1/24. Is this coin still running?

Looking back over the 8 months one thing I can say is interesting and somewhat unexpected was the difficulty in growing an ecosystem where there is a Foundation essentially giving something away for free.

I was watching "Brain Games" the other night and this segment kind of made sense that way: https://www.youtube.com/watch?v=nAa1OBWJ9Y0

kamronk, Lightsplasher: I love all of these ideas and I'm onboard for content funneling and IRC rain give-a-ways. I'm not the best guy technically to set these up but I can try to help and also there is some budget still available for motivating other folks. Let me know and we can try some specific things.

One caveat is the new coin release is sort of a cliffing event in my mind; it would be best to begin any efforts after the coin plumbing was reset so any coin exchange or other mechanism that needs to occur affects the least number of people. Thoughts?

The block explorer we used to have here went down in early Dec and then came back in the middle of the month for a stretch and then went back down again. You could message "CryptoBlox" and ask him about it (Which I've also done). Seeing more interest might be helpful for him to know it's worth the time. The current coin dev had a working block explorer up for awhile here, but it's offline so I'll ask him about it as well.

I like these ideas and the enthusiasm so I am glad you posted.

kamronk, my last major update was this comment. I am still working on the coin from the renewable production and carbon offset side of things. I'm in contact with a new interested party that is working on a new PoS/PoW upgrade. This serves to fix the main technical issue that the Foundation does not receive all of their intended coins and provide for some additional updates/upgrades. I'll of course keep everyone updated as to the progress. Pending this release, my plan is to immediately restart and up-armor my efforts to reach new producers and market the coin as a carbon offset credit.

Bitffinex alone shows a big red 3-day bar of >500k bitcoins starting Jan 13th. Somebody big is selling. Until they stop and then renewed interest in bitcoin begins anew it'll keep falling.

This five minute video on global debt economics is worth watching. I haven't gone "full retard" on bitcoin and gold investing, but a little here and there, though I think more importantly, it's just really key to be paying attention at this point in time. Some big shit in the theater of global finance is going on right now and 2015 could very well be a pivotal year in how this all shakes out.

yes, I've seen this too, this is a known bug.

I wonder for folks who deny AGW completely and given a mechanism like GreenCoin, or something else similar that comes along, a lot of them quietly participate anyway because it would simply be too lucrative to miss if out if they were wrong.

me thinks BTC may go to $90, LTC under $1. It would certainly need to be this low before I bought any more.

RE: Not using PoS -- the coin works currently by splitting the rewards with the winning miner and the Foundation, the latter of which then distributes them to renewable producers to effectuate the carbon emission offset calculation. PoS cannot service this requirement easily.

I have been discussing coin upgrades with some folks and PoS has been taken off the table, as info.

The polar bear has come to represent more of a symbolic relationship of the forced nature of species adaptation. The jury is still out on the how these changes will actually manifest for any specific species. How far a "polar bear can swim" is only one aspect of it's life cycle. Probably more important is how the food chain will change from the bottom up, given warming in the region of +10 C (18F) or more. And most people, honestly speaking man, don't care about bears, they care about themselves, and "global warming" or "climate change" (whatever the words du jour are) is about change for people too. And change can be harsh, which is scary.

I will not speculate whether or not you you simply have a fear-based agenda to grind about a "New World order dictatorship" which is sort of a thin conspiracy theory poorly supported by physical evidence about ice caps (and which is grossly incomplete). In the theater of competing conspiracy theories, one of fossil conglomerates disseminating misleading "scientific" data for their own profitable agenda (more accurately, their interpretation of the data) is far more plausible than one of a new global dictatorship social order, financed by a carbon tax that hasn't even begun to be enforced. While discussing conclusions from grossly incomplete data I want to also point out that plants do indeed need CO2 to grow, though obviously don't need >400 ppm to grow since they've been doing just fine for 500M years at 50-80% of that. However we need CO2 back to 350 ppm in order to survive catastrophic changes for ourselves and more importantly our children.

However, with that said, you're actually here to help prove a point where you and GreenCoin are in agreement: Carbon taxes are not effective and That's Bad. Or at least, in our position, carbon taxes and cap and trade systems are grossly inadequate constructs to solve The Problem, and therefore are doomed to failure regardless of the level of implementation they ever reach.

If you didn't research GreenCoin before posting, and merely bristled at the polar bear picture, let me explain the central premise: GreenCoin is a mechanism that serves a for-profit reduction of carbon output through a simple system of incentives for renewables that carry a socially-derived, open-market value. Some finer points:

- GreenCoin is owned and traded by individuals
- People buy and sell GreenCoin for their own selfish purposes; to try to make money or not, to try to help AGW or not (John Galt would be proud), or whatever their personal reasons are. That's a major coup de grace against the "New World order Dictatorship" advancement. So we are on the same team here.
- Government involvement is not necessary
- Participation is voluntary, you are free to participate in GreenCoin or not
- GreenCoin is not a tax or other punitive measure on fossil based production. It's merely a socially determined, value-added incentive for carbon-mitigated production. And I'll do you one better: fossil-based producers can go start their own "FossilCoin" and solicit certain folks, The Great World Defenders of Massive, Coordinated Scientific and World Government Co-Conspirator Carbon Fraud, as buyers. Hence the term "free-market system."

thanks for stopping by and posting, I think these are important things to be discussing.

GreenCoin could switch to a counterparty (or other asset-based) coin. Thoughts?
