Title: [ANN][GRA] Graincoin - PoW/PoS coin | Fast, secure | Version 1.6.2 Release Post by: bee7 on June 02, 2014, 09:42:37 PM http://s21.postimg.org/s7lohxh9j/ga_banner1.png http://s24.postimg.org/7kdob0gsl/ga_banner2.png http://s2.postimg.org/w3bfzfb49/ga_banner3.png Version 1.6.2 Released. Download links for Windows Client and source in github are updated. To save your time and resources the separate link for blockchain data is provided in downloads section. A grain is a unit of measurement of mass that is nominally based upon the mass of a single seed of a cereal. From the Bronze Age into the Renaissance the average masses of wheat and barley grains were part of the legal definition of units of mass. However, there is no evidence of any country ever having used actual seeds or cereal grains. Rather, expressions such as "thirty-two grains of wheat, taken from the middle of the ear" appear to have been ritualistic formulas, essentially the premodern equivalent of legal boilerplate. - from Wikipedia Graincoin (GRA) Graincoin is a PoW/PoS coin that is designed to be the unit of cyber-coin. It has a total of 50 billion unit to be released, through a fair p2p mining process. It is fast, secure and have sufficient coins for circulation so it can be used in real daily shopping. Graincoin is from the family of PPCoin/Novacoin with latest available algorithms that fixed various problems in the PoW/PoS coins. As compared to the PoW only coins, the proof of stake coins are more resilient to 51% attack. Also it is a long term energy-efficient crypto-currency since not all coins are obtained by mining. Each graincoin block provides random 1024 - 2048 grains initially. It also provides rare superblocks. The coin uses hash-based algorithm to determine superblocks based on the number of 9s in the previous block hash. It works as follows: - the hash contains six 9s or less: regular block - the hash contains seven or eight 9s: 8 times the regular block (about 5% chances) - the hash contains nine or more 9s: 64 times the regular block (about 1% chances) Premined 1% as reserved bounty and reward for developers, giveaway, pool, explorers, etc. Graincoin also provides 5% annual interest on the grained held. The interest will be paid about every 2 weeks. Specifications - scrypt - 30 seconds block target - 1024-2048 grains per block for normal blocks - 8 times or 64 times the regular payout per block for super blocks depends on the number of 9s in the previous hash - Difficulty retargets every block - mining payout will be halved every 90 days (259200 blocks) - minimum payout per block 1 coin - Total grains will be 50 billions - 6 confirmations for transaction - 50 confirmations for minted blocks - PoS interest 5% yearly - PoS min age 10 days - PoS max age 30 days - Ports: 11054 (connection) and 11055 (RPC) Official websites: http://www.graincoin.net http://www.graincoin.org http://coinmarketcap.com/ Graincoin on Cryptoarticles: http://www.cryptoarticles.com/crypto-news/2014/1/25/coinpayments-now-supports-grain http://www.cryptoarticles.com/crypto-news/2014/1/15/grain-the-future-unit-of-cyber-coin http://www.cryptoarticles.com/crypto-news/2014/1/18/grain-new-wallet-released-version-14 http://www.cryptoarticles.com/crypto-news/2014/1/23/grain-more-valuable-than-yould-think Exchanges None to the moment Block Explorer (http://explorer.graincoin.net/) http://explorer.graincoin.net/ Shops, Services, Games that accept GRA None to the moment Socials, Discussions etc Twitter (https://twitter.com/Graincoin) The following socials, discussion groups etc are sponsored by Grain mining members.

Using the same wallet file if I open in version 1.4 it says 308 confirms and transferred okay, but not received on other end, if I open the same wallet file in version 1.5 is stays at 0 confirms and shows it as deducted from my available balance. Anyway to get these coins back or to complete the transfer? I have reloaded the block-chain about 5 times now but no help.

If these coins were sent while the wallet was on the wrong fork (that most likely had place as v1.4 is incompatible with v1.5) and the coins were mined/received before the previous hardfork at block 310000 then they should be recovered.

I can't sync my wallet. Are there any nodes which are working? Thanks Athuros Title: Re: [ANN][GRA] Graincoin - PoW/PoS coin | Fast, secure | Version 1.6 Release Post by: bee7 on June 03, 2014, 09:32:07 PM Hi I can't sync my wallet. Are there any nodes which are working? Thanks Athuros Although the IRC seeding is fixed and working, here are some nodes for you: Code: addnode=2.248.164.206 Also, please note, that the blockchain file with related LeveDB files is available for download (http://sourceforge.net/projects/graincoin/files/blockchain/blockchain.zip/download). It has about 660k blocks. Take to account that the indexing of that amount of blocks itself requires quite sensible time. Title: Re: [ANN][GRA] Graincoin - PoW/PoS coin | Fast, secure | Version 1.6 Release Post by: fastrabbit on June 04, 2014, 12:55:02 AM Grain, that's a really interesting coin, I especially like the idea that it will link to the real grain market! Awesome ideas!
BTW, what are the new things in version 1.6? Title: Re: [ANN][GRA] Graincoin - PoW/PoS coin | Fast, secure | Version 1.6 Release Post by: athur0s on June 04, 2014, 01:02:15 AM Hi I can't sync my wallet. Are there any nodes which are working?

Awesome ideas! BTW, what are the new things in version 1.6? The idea to link to the real grain market, at least as it was outlined by hozer in https://bitcointalk.org/index.php?topic=361503.msg6980579#msg6980579 , requires completely different emission model. So, I doubt this would happen to the GrainCoin. However, if the discussion of this subject would end up in something good to try then we could implement it as a separate project. There is a number of fixes. The two most important problems fixed are excessive orphaning and the bad wallet response time when it has any inputs to perform PoS minting. Also, a few optimizations to the block tree storage and block handling have been done. These optimizations save approximately 20% of CPU time in block handling and drastically decrease the wallet startup time. I am planning to include in the future release the CoinControl support. Title: Re: [ANN][GRA] Graincoin - PoW/PoS coin | Fast, secure | Version 1.6 Release Post by: bee7 on June 04, 2014, 01:39:35 AM I have been told that the splash screen in GUI version has the old version number. If this makes sense for you, please download the fixed one: http://sourceforge.net/projects/graincoin/files/v1.6/graincoin-1.6.0.0-win32.zip/download. The download link in the OP is updated as well.

Thanks for the info, grain market is interesting. Though I am not sure how many people will be interested. Coincontrol is very easy to add, some other coins added it, so you can just see the diff, for example, the MintCoin: https://github.com/mintcoinproject/mintcoin/commit/af6c0b9debca664975fbe570d6ac17acf92094f0 took me last time 20 mins to add it for another coin... BTW, are you going to remove orphans from the tx display? I got a lot orphans hanging there, pretty annoying.

Yes, I know this. I did not do it with this update just because the lack of time and urgent need to release more important fixes. Also, this addition does not require a hardfork, so may be issued anytime. Quote BTW, are you going to remove orphans from the tx display? I got a lot orphans hanging there, pretty annoying. Let's see how it would perform after midnight. Even now, before time-triggered fixes are in effect, I see much less orphans in my wallet. If it is still necessary, then I add an option to the interface not to show orphaned blocks.

If it is still necessary, then I add an option to the interface not to show orphaned blocks. Devs, 2 things: 1) Please change the sorting on transaction list to be on Date, not on Status, so we don't always see these orphans floating on top. This is a 1-2 line change in the filter->sort method in Overeviewpage.cpp. The best, of course, is not display those orphans in tx list (a little more work). 2) To truely revive Grain, you need something really good. The key is to implement anonymous features in wallet. This will really differentiate Grain from other coins, and send Grain to the Moon! You can start with a mixer like in XC (although they hyped like crazy, in fact they have only a simple mixer for now, which is traceable), gradually making it non-traceable. This will be really big for Grain! With Grain's dev team (bosian/bee7 and maybe others I don't know behind the scene), this surely can be done! I've been following Grain for some time (and hold some grains), the dev team was impressive. So come on guys, realize the good value of grain for all the community!

There are issues with network. Please hold off transfers and PoW minting until further notice. Title: Re: [ANN][GRA] Graincoin - PoW/PoS coin | Fast, secure | Version 1.6 Release Post by: bee7 on June 19, 2014, 01:44:23 AM http://sourceforge.net/projects/graincoin/files/v1.6/graincoin-1.6.1.0-win32.zip/download the links in the OP and source at github are updated. Still hold off with transfers and PoW minting: let the network recover, please. Hold off with update please. I need some more time to analyse the data I succeeded to get. Title: Re: [ANN][GRA] Graincoin - PoW/PoS coin | Fast, secure | Version 1.6 Release Post by: bee7 on June 22, 2014, 02:10:17 AM Status update:
First, a small explanation what happened. At some point a node generated the block that had quite high trust score but were not propagated fast enough through the network. Some nodes accepted it but others rejected due to diff adjustment limiting filter that is originally designed to prevent the flooding of the network with blocks having too big PoW/PoS (the smaller the value the more work is required to produce a block). Originally, when a node receives such a block then it bans the sending peer immediately for 24h by default. So the net got split in two parts (or more). Then these parts live isolated for 24 hours and grow their own forks. In 1.6.1 I removed this banning of a peer to maintain the network connected anyway and some other small fixes that I hoped would solve the problem. Apparently it did not help as some nodes remains stick to their forks even after they got reconnected with other nodes. Thanks to the data kindly provided by harveyweizhao (https://bitcointalk.org/index.php?action=profile;u=24010) I analyzed the states of two forks and found the problem that keeps it from switching to the proper fork automatically. Atm I am testing the fix and I am planning to release the 1.6.2 tomorrow or day after tomorrow. I still warn you not to make any transfers until you update to 1.6.2. The both exchanges were notified timely so they stopped the daemons. As soon as I see that the net is recovered after 1.6.2 deployment I will ask them to restore the services. Stay tuned.

The coin age of the inputs participated in such blocks creation is not spent as the blocks eventually get orphaned, so they are not a part of the best chain.

It seems my attempt to negotiate the block explorer outsourcing has failed. First I doubled the requested 0.05 BTC lifetime fee as I was aware that ABE scripts are incorrectly calculating coindays destroyed, fees, etc. for blocks containing superblock reward transactions and I wanted this to be fixed by the explorer op. Then I doubled this amount again as he was impressed by the blockchain size... to no avail. So I did what I said him: I rented a VPS for that amount, fixed and deployed the blockchain explorer myself. Here you are: http://explorer.graincoin.net/ It is an official one. The OP is updated.

This is why I have dumped everything. I was just testing some stuff, but you could time warp the shit out off this chain if you wanted (I didnt, I have only mined 2h in the future without forking the chain). This 2h time change has fucked up the diffculty for 2 hours. You could time warp and double spend as much as you wanted (which I didnt). PoW should be removed, its only a weak point with this low block rewards. I have only mined with ~250 Khash/s.

It's still breathing and has a weak pulse ... This is probably someone else doing the same shit. Really? Could you elaborate, please, the complete scenario. After reading stuff about BCX, I was curious how will the Grain blockchain deal with blocks that have a faked timestamp, so I have run a test. I have changed the system clock time on my miner 2 hours into the future and started mining. The network has accepted my blocks and I have also solved PoS blocks with a faked timestamp. I have tested this a second time without a PoS block being solved and the network has rejected my PoW blocks. Normally I get 66-75% stales/invalids, but with the faked timestamp I have got only 40-50%. The PoW difficulty was also lowering! After restoring the normal time I could still mine with a low difficulty for a short time, but then the difficutly has raised without PoW blocks being solved. The difficulty was so high, that I could not solve any (or almost none, I cant remember) PoW blocks until 2 hours since my last block with a fake timestamp have passed. My client also didnt solve any PoS blocks. I cant tell how exacly the network did behave during this 2 hours, because I had only one client running, but I have noticed a very big interval between the blocks. I can remember that the highest interval between block (according to my client) was over 10 minutes (maybe even 20). After the 2 hours, my client have solved a shitload of PoS blocks instantly and the difficulty was back to normal. I could made a copy of the chain and do the above and mine faster than the network. I could also play with the timestamps on my private copy of the chain and I would definitely solve the blocks faster than PoW and PoS of the network combined. It is also a bad idea of swisscex to accept Grain deposits after only 6 confirmations.

Might be it worth to discuss such doubts with the community, dev, other coins devs in the first turn than to just dump all that you have? Did you do any thorough study how that could be applied to graincoin particularly. The case that you mentioned, when the PoS diff was stuck at 1.5 for several, was just due to no PoW miners with a notable hash power were active at the time. It took me a few minutes to solve that block with 3.6Mh rig to push it through. Although the current set of the timing and other parameters that control the behavior of the blockchain is really not ideal and I am going to change some of them (the max clock drift among them) to improve the network security, ATM I have more important things to work on. Without these things implemented any other so called 'improvements' are just a dust. They will not make graincoin any different so it could get what it should deserve. Edit: the lack of my frequent postings here is not due to I am absent: you could easily see that I am online every day, so I am not gone. I just think that meaningless posts like "to da moon" does not create any value of the coin.

The max clock drift is currently 2 hours. It came from original bitcoin client and for bitcoin network it is not a problem at all. As I mentioned, I am going to change that parameter, but it requires a hard fork, so I would like to collect all such hard changes together. Also no legitimate node would accept the block that is in the past relative to the GetMedianTimePast(). You could of course (and it seems you did :) ) make a tweaked wallet that would persistently submit the blocks with time 2 hours in advance. This would influence the difficulty of course, but will not stop the network from generating new PoS blocks as I assume that even before your dump you were not in possession of 51% of all coins. So even if you managed to bring the network's PoW difficulty to some high value that 'stopped' the current network's hashing nodes from producing PoW blocks and you started to create your own fork to override main chain you most likely would fail as the cumulative trust score of your fork would be less than the network's one: the block trust score is a function of the block's difficulty and a history of last 12 blocks. So, to achieve the better result you should have more resources (both the hashing power and the supply) than the rest of the network. Taking to account the currently low network hashing power it is of course possible to make successful doublespend, but as I already said I am not going to pump the situation with the thin air. As the coin presently has very low value I do not see any reason to care much about this: when and if the graincoin get well valued then miners come.

I've never, and few have, been a pool operator. I don't know of any books or classes to take. :) I'm still learning the system, database structure and problems that arise and how to deal with them. Bitcoin (alts) have been a hobby of mine and it's something I've wanted to do for a long time. I finally got around to setting something up using NOMP and MPOS. To put a public pool online ... I'd like to have proper hosting, separate systems for daemons, databases, stratum and the front-end web. All with proper security.... I'm currently using a few virtual machines to learn the ins and outs on a residential class Internet provider. One problem I've been having (only with Grain) is with MPOS's findblocks cron where it error out with E0081-Failed to insert new block into database. Followed by a E0062-Block has no share_id,not running payouts. It appears to recover after forcing a re-run on the cronjob.... Perhaps due to the low difficulty and rapid block finds. If anyone would like to mine Grain, Orbitcoin, Gamecoin, Fireflycoin, Teacoin or Zetacoin and can accept the learning curve of the operator. Send me a PM. I only ask you to set your payout threshold low and don't leave a large balance.

Yes. I am currently in the process implementing several changes (enhancements) in the protocol that I need for further development. Unfortunately, many of these changes require the hardfork, so I would like to release them all together to minimize the impact. The coincontrol will be included. If you need it urgently I could make a 'maintenance' release of course.

However, I am going to implement the maximum PoS block reward: many of you are merging all their coins into a single input and running a wallet once a month or even more rare. According to the statistics I collected, presently only 1/3 of existing supply is participating in PoS generation on a regular basis. This is not good for the network security at all. At the same time I did a few optimizations to the PoS generation code to make it even less energy consuming than before (and thus faster and less CPU intensive) to compensate the need to have more than 1 input in your wallet. These optimizations are being tested presently. Also, the automatic low inputs merging policy is under reconsideration now. Apart from other things I am going to introduce in the coming hard fork, I am seriously thinking on switching hashing function. There is a number of reasons, the most important of which is the time necessary to validate a block received from the network. First, I believe that memory-intensive algorithms like Scrypt-N are not serving their purpose anymore: there are Scrypt ASIC miners on the market, so apparently the memory is not a barrier for ASIC developers. From the other hand, although there are many different options like X11, X... I think it is an overkill for purpose to make the coin ASIC resistant. At least it makes block validation quite CPU-time expensive. After looking at spectrum of different hashing functions already implemented and adapted by different coins I picked the hashing function used by the JackpotCoin, the Jackpotcoin Hash Algorithm V2 (https://bitcointalk.org/index.php?topic=584481.0). This is a combination of a single keccak512 transformation followed by eight rounds of random selection (based on current internal state of the hashing 'engine') of groetsl512, skein512, blake512 and jh512 transforms. The plain C implementation (https://github.com/rtc29462/jackpotcoinhash/blob/master/jackpotcoin.c#L84) of this algorithm is 30 times faster than SSE2-optimized version of the Scrypt, thus it is 30 times more energy efficient in terms of CPU computations on Intel platform (for the GPU I see the four times higher hashrate and two times drop of consumption at the wall compare to Scrypt on R9-290 and R9-280X, the Nvidia chipsets produce better ratio though (http://cryptomining-blog.com/3503-crypto-mining-performance-of-the-new-nvidia-geforce-gtx-980/)). From the other hand, it is quite complex to be implemented in the silicon in the nearest future. Please share your thoughts on this.

Also, the 64bit linux build utilizes 640K resident RAM. Although, ARM is 32bit, so it should consume less RAM (the pointers are two times smaller) I do not expect the memory requirements to be significantly reduced. Let's see if it is feasible.

Would you consider updating the OP to refer to the "Official Websites" that no longer recommend updating to v1.4 or v1.5. Since we're on v1.6.2.0 now and there are many dead links at some of the official websites -- some cleanup of the OP is probably helpful for the newcomers who will become interested in Grain for the first time. What do other members of the community think about the best website we should be referring new users to who are interested in Grain for 2015?

Please vote Graincoin for being added to exchanges: For cryptsy: https://cryptsy.freshdesk.com/support/discussions/topics/44936 A grain is a unit of measurement of mass that is nominally based upon the mass of a single seed of a cereal. From the Bronze Age into the Renaissance the average masses of wheat and barley grains were part of the legal definition of units of mass. However, there is no evidence of any country ever having used actual seeds or cereal grains. Rather, expressions such as "thirty-two grains of wheat, taken from the middle of the ear" appear to have been ritualistic formulas, essentially the premodern equivalent of legal boilerplate. - from Wikipedia Graincoin (GRA) Graincoin is a PoW/PoS coin that is designed to be the unit of cyber-coin. It has a total of 50 billion unit to be released, through a fair p2p mining process. It is fast, secure and have sufficient coins for circulation so it can be used in real daily shopping. Graincoin is from the family of PPCoin/Novacoin with latest available algorithms that fixed various problems in the PoW/PoS coins. As compared to the PoW only coins, the proof of stake coins are more resilient to 51% attack. Also it is a long term energy-efficient crypto-currency since not all coins are obtained by mining. Each graincoin block provides random 1024 - 2048 grains initially. It also provides rare superblocks. The coin uses hash-based algorithm to determine superblocks based on the number of 9s in the previous block hash. It works as follows: - the hash contains six 9s or less: regular block - the hash contains seven or eight 9s: 8 times the regular block (about 5% chances) - the hash contains nine or more 9s: 64 times the regular block (about 1% chances) Premined 1% as reserved bounty and reward for developers, giveaway, pool, explorers, etc. Graincoin also provides 5% annual interest on the grained held. The interest will be paid about every 2 weeks.

Community. In October '15 my host got crashed and I had very big problems in real life so when I got some time to look into the thing the network was already down for several months. One of the latest supporters repeatedly asked me in PMs for almost a year to bring up the network back. He kindly sent me his blockchain file that was a bit longer than mine. As I stated already it has 2.2M+ blocks with total supply ~1.2bln coins. I will bring up a block explorer with that chain shortly, so you could explore it. At the same time, I found many discussions on BCT regarding possible vulnerabilities of PoS and hybrid coins, please read these two threads: https://bitcointalk.org/index.php?topic=1709776.0 https://bitcointalk.org/index.php?topic=551861.0 Although I am skeptical about "nothing-at-stake" issue, I see a real problem with low PoW rewards: the emission schedule made it really not profitable to mine Graincoin anymore. There is a real risk of double-spend possibility with low PoW difficulty (i.e. one produces a row of PoW blocks with transaction in a first block and then publishes a PoS fork that overrides the original transaction) Taking to account that the protocol targets to produce at most four PoW blocks each twelve blocks we still have to mine ~30k blocks with average reward of 6 coins a block, then 65k blocks (259k/4) with average reward of 3 coins and 65k blocks with average reward 1.5 coins. Then the reward would be 1 coin a block forever. Roughly speaking, the mining would produce approximately 500k coins in the following 7 months counting from now and then it would generate 21900 coins a month. So, I am for switching to pure PoS now (looking at the BlackCoin example that behaves just fine for more than 2 years being pure PoS). There is a couple of additional topics I would like bring to discussion. The first one is target time. Presently it is 30 seconds a block and produces ~0.5Gb of blocks data a year and ~1.2Gb of indexing database a year. IMO this makes no real advantage: my experience shows that most exchanges and payment processors picks such a number of required deposit(payment) confirmations that your account get credited (the payment get confirmed) roughly one hour after the transaction is mined. Thus, I propose to increase the target time to 2.5 minutes - this would lower disk and memory usage. The second thing is the existing blockchain, i.e. history: most blocks starting from July '14 are empty (have no transactions apart from coinbase and coinstake) and only consume RAM. So I propose to swap the chain. To make the swap fair and verifiable and to bootstrap the pure PoS network I am going to proceed as follows: The minimum coinage to stake is 10 days. That means that any TXO is eligible to stake after it get 10 days old. In case of a fresh chain the network has to produce somehow 5760 blocks (if the target time is 2.5 minutes) before the first stake block could be minted. Currently the chain has approximately 1M unspent transaction outputs. These 5760 blocks are enough to evenly distribute 1M unspent transaction outputs in coinbase transactions thus reproducing the existing total supply belonging to original owners. To allow anyone to (manually) verify that any particular TXO in the new chain exists in the original chain and the amount matches, the scriptPubKey of each TXOs in these first 5760 PoW blocks would be composed this way: Code: OP_PUSHDATA <txid> OP_PUSHDATA <n> OP_DROP2 DUP HASH160 <hash> EQUALVERIFY CHECKSIG here <txid> is an id of transaction in the original chain, <n> is an output number in that tx and <hash> is a destination address from the original tx. All these blocks will be signed with a keypair the public part of which will be hardcoded into CheckBlock function. Also, CheckBlock function would check at block 5760 that total supply is equal to the one of original chain and will not accept PoW blocks after height 5760. These 5760 blocks will be PoW-mined myself (with no extra reward) and then the PoS should drive the network. Please share your thoughts, objections and ideas. bee7 Title: Re: [ANN][GRA] Graincoin - PoW/PoS coin | Fast, secure | Version 1.6.2 Release Post by: hesdeadjim on March 11, 2017, 02:26:11 PM that sounds like a great plan and a well thought out execution.
the only problem that i've seen with pure POS coins in general is that it is very difficult to move the chain while staking only. many chains get stalled for weeks or longer because of this. some dev's of hybrid coins continue to mine empty blocks after the pow phase is over the keep the chain moving but as you said, hybrid coins have a risk. another possibility is to try to list the coin at POSWallet very prior to releasing the POS wallet publicly so that the group staking will keep the chain moving as well. Thanks again for the update and sorry to hear about your troubles. :) Title: Re: [ANN][GRA] Graincoin - PoW/PoS coin | Fast, secure | Version 1.6.2 Release Post by: bee7 on March 11, 2017, 03:21:18 PM that sounds like a great plan and a well thought out execution. Thanks, I really have been thinking on the topic a lot.the only problem that i've seen with pure POS coins in general is that it is very difficult to move the chain while staking only. many chains get stalled for weeks or longer because of this. It's true if most coins get to the exchanges wallets and(or) coin get lack of interest. another possibility is to try to list the coin at POSWallet very prior to releasing the POS wallet publicly so that the group staking will keep the chain moving as well. This is is bad idea: it makes POSWallet holding huge amount of coins (I hate the exchanges for the same reason but this is unavoidable evil) some dev's of hybrid coins continue to mine empty blocks after the pow phase is over the keep the chain moving but as you said, hybrid coins have a risk. This is not good solution as well: if anyone is allowed to mine an empty block then this opens a lot of possibilities to manipulate the block chain, otherwise if, say, me would generate an empty blocks signed with above mentioned private key then this put the chain under centralized control. From my point of view it is much more correct for a dev to stake than to PoW-mine: the main idea of the PoS is to make the process more energy-efficient.

Also it will took some time for ABE to build the index. So, I expect all this to be completed in three to four days. Hi bee7, Yes, I agree it will take several days for Abe to index the Grain blockchain. A couple of years ago when I had prepared a local Abe instance with Grain it took many days. I suppose if there literally was no swarm then there would be no blockchain movement beyond December 28th of 2015 and thus nothing to lose. If some pair of users had a copy of the blockchain beyond December 28th of 2015 then they'd be the only ones staking and working on it. Your post in the channel is fair warning for them to have spoken up or to speak up soon. Once my coin daemon finally syncs with the chain, I was thinking of running through the linearize scripts to produce a linear bootstrap.dat for the case where I would need to bring another wallet online. So long as that is successful I'll share it here for you and others. I'm going to read through the two threads you posted about earlier for PoS and hopefully comprehend them by going through slowly and diligently. Sounds like you have a solid plan and don't hesitate to ask the community for help if you need it.

I spent some time studying the Grain blockchain over the past several days after having synchronized with peer nodes which had been put online by community members to help assess the state of the network. The analysis was performed by waiting until the synchronization had completed; and then looking at the timestamp of blocks on the tip of the chain. Working backwards; 2017 minting resumed at height 2210497, 1489207835 seconds after the Unix epoch, Saturday, 11-Mar-17 04:50:35 UTC. Prior to this, our blockchain ran mostly uninterrupted through height 2210496, which was minted 1458673397 seconds after the Unix epoch, Tuesday, 22-Mar-16 19:03:17 UTC. Correspondingly, there is a gap of 353 days, 9 hours, 47 minutes and 18 seconds where no evidence of any blocks having been minted by any Grainers has been found. If there are Grainers with a blockchain built on the tip of block 2210496, which continues further into 2016; then we would like you to come forward so we may sync with your node(s) and analyze the data. Based on the above information; it would be logical for the proposed chain swap to happen using a snapshot of the blockchain at height 2210496 unless new data is presented to the community showing a swarm having continued to mint new blocks after March 22nd, 2016. For mutual reference, a copy of the "last block" minted in 2016 is included with this post. Code: {Therefore, I suggest accepting a checkpoint block and stake modifier hard checkpoint at height 2210496 to designate consensus. When and if another community member shares their blockchain data from the rest of 2016, it may become appropriate to add another 2016 checkpoint block as we begin to reorganize the network. The above would lead to updating the client code so peers would reject blocks from any forks before the checkpoint and then to the proposed chain swap when Grain would be started from scratch. Additionally, I have rendered a linear copy of the blockchain at height 2210496 in a bootstrap.dat file which I am prepared to share with the community members. I am interested in hearing from anyone and everyone with thoughts which contribute to rebuilding the GrainCoin ecosystem. To be successful, Grainers must do more than just hold their coins as has been the status quo for the last dozen or more months. Thank you very much Miner-TE! I am grateful you responded to my private message so quickly and put your node online for me to synchronize and assess the state of the network.

Best Regards, -Chicago Title: Re: [ANN][GRA] Graincoin - PoW/PoS coin | Fast, secure | Version 1.6.2 Release Post by: bee7 on March 19, 2017, 05:04:58 PM Dear fellow members,
thanks to the Chicago's effort we have recovered a bit longer history than I had initially (the chain I had is a sub-chain of the one Chicago got). As nobody posted anything different I assume this is the maximum we could achieve in this respect. I already set up the block explorer with that chain at http://explorer.graincoin.net so you could explore it without the need to download and re-index the blockchain bootstrap file yourself. However, we will decide shortly where to host that file and make it available for your reference. Also, I would like to mention that Chicago being an experienced in cryptocoin related development did many things for the sake of good of Graincoin during past days and I am happy that now we could have not a single developer but form a team backing the coin development. The team is not closed: this is an open source project, so anyone who feels himself capable and willing to participate is welcome. As no objections were expressed to my proposal (https://bitcointalk.org/index.php?topic=636580.msg18145999#msg18145999) on further steps in development we will start to implement the coin swap according to the scheme described. At time of coin swap we will release a new wallet based on more recent bitcoin client software. Most likely the new wallet will be based on bitcoin v0.12.3 code to adsorb as much development as possible. Definitely it will not be a v0.13 code or later as it makes no advantage for us: we will not hit block limit any soon. Although the segwit introduced in v0.13 also solves transaction malleability problem, we would prefer to postpone its possible integration until we see it really needed for Graincoin. The development tree is moved to the new location at github (please see https://github.com/graincoin-project/graincoin ) to allow better level of team collaboration than the previously used single user account allows. bee7 Edit: the OP is partially updated Edit2: edited for clarity Title: Re: [ANN][GRA] Graincoin - PoW/PoS coin | Fast, secure | Version 1.6.2 Release Post by: hoertest on March 19, 2017, 07:05:49 PM glad to see this alive, i found the old wallet and startet it , it deosn't sync right now , is it enough to find my address in the explorer with the grain in it to take part in the swap?

Hi Glad, Basically, the file can be downloaded, (re)named to be bootstrap.dat and then used with graind, to fast track the initial sync. Once the sync has completed it can be used with specific addnode entries to connect with other peers to (re)establish the Grain swarm.

Hi Glad, Basically, the file can be downloaded, (re)named to be bootstrap.dat and then used with graind, to fast track the initial sync. Once the sync has completed it can be used with specific addnode entries to connect with other peers to (re)establish the Grain swarm.

Hi Glad, Specifically, you would open your .Grain/ directory where the wallet.dat lives and place the file there and then start Grain's daemon with a -loadblock=bootstrap.dat there. So first rename the file to be bootstrap.dat and then put it into the coin daemon's directory and then start Grain w/ the -loadblock argument as specified. You'll notice it starts reading the file and processing blocks immediately and then once it has finished, the file gets automatically renamed to be bootstrap.dat.old.

The timestamp of the last block I found on the network is 1491352187 at height 2256566. I'd like to sync with your node to see if it is the same chain just with more work. Would you ask your Grain.conf to enable the IRC functionality so peers may find you easily? Best Regards, -Chicago do you know what the stage is for the new release? If bee7 quits what will be going to happen then?

If you're configuration file has irc=1 you should be able to find my grain node. If peers are on two or more different chains, the chance that a syncing client will end up on the 'wrong' one is still significant. AFAIK the sync process is essentially random, so any blocks offered by a peer which extend the local chain will be accepted, regardless of whether they'll properly match a future checkpoint. I've already gone onto the wrong chain and become stuck at the hardened checkpoint (which doesn't match the local chain I've been sent by peers) a couple of times. Really need to -connect to a specific node to ensure the sync stays on a specific chain. If you're not willing to post your IP here, could you PM it to me?

We have to consolidate, merge the rightblockchain in operational test status. We have three chains = mentioned, lets find the right one and share this blockchain online here to compare. So we can try to setup the synchronising again. Look for issues and solve the checkpoints in order to have a stable distribution, we might need an update. Somebody have any suggestions?
