This is just a suggestion,

I see a big potential on the implementation of atomic cross chain swaps. I don't know if it's possible to integrate / implement that on bee, but I see it as good direction to point to.
Also, any other feature that facilitates / enables decentralized exchange between bee and onther cryptos will be great to have (in my opinion).

What do you think?

Good suggestion but I would think that could be quite a tough one to implement. Blocknet is though making their own btc wallet running on top of blocknets atomic swap so perhaps it would not be hard to do that for bee.

Although i wouldn't really know.

Graham would know better the work needed to integrate something like that.

Did anyone as yet pull open this file and find allcoins wallet? so we can black list it?

I am a computer illiterate and don't dare install anything unless under my cousins supervision who is away ...

Fair enough. Just identify the offending addresses and I'll strip them out of the database with a SQL query.

Cheers

Just a silly question, but what do we do with this update? How do we use it? I have been too busy at work, so I have missed this thread for a few hours.

It's tediously detailed, half a dozen posts up-thtread: https://bitcointalksearch.org/topic/m.21967425

It's a (i.e. one) snapshot of the public ledger, the set of UTXOs dumped in SQL for editing to the community's satisfaction. I'm informed that the community collectively considers some tx recorded in the ledger to be undesirable and the ledger transfer process (as I have described it above) offers an opportunity at this point to erase those tx from the set of UTXOs which will form the public ledger for the new hard-forked Bee blockchain.

I'm unashamedly ignorant of the events and nuances of the community's collective experience over the last three years. As any decision to edit the public ledger is a departure from the currently-pertaining social contract, it will be inherently controversial. Considering and accepting the consequences of this change are quite properly a sole concern for the community.

It's not that I don't consider myself part of the community, I do - but I feel a need to effectively “recuse” myself from any actual decisions, given that one strong expectation will be complete transparency of the process.

To make your own snapshot of the Beecoinv2 blockchain, all you need is a synced Beecoin node, Python (I have 3.5 locally) and Postgres (9.5 locally), the script in the gist, a fast m/c and an afternoon.

Cheers

Graham



Yes I certainly would like allcoins proven address taken out of action.

These are proven scammers I would not expect anyone in the community would like to see our shares in beecoin diluted by those that stole our coins in the first place. But if some object then I would be interested to explore their reasoning. Of course open mindedness in all things is best.

the XPS is back up again

make -j6 is definitely worth the pain.

Righty-ho, now that I have finally managed to get the beecoinv2 daemon synced, it's time to think about the process of transferring an amended public ledger.

The technical side of the process is straightforward. The client code does all the processing:

Store the input/output type and value of all of the transactions in block 1, 2, 3, ... n, deleting any outputs that later appear as inputs.

The result is a database of transactions that have not yet been spent and which, when summed by address, provides an overall balance for each address.

Preliminary working-but-not-yet-proven Python code to create such a beast is here:

https://gist.github.com/gjhiggins/44e8b84787db4ba188623c17097b15f3

The address/balance pairs are hard-coded as (essentially) coinbase-generated transactions which are included in the “genesis block”, block 0, the root of the chain and whose block hash and Merkle tree root hash have to be hand-inserted into the program code before it can be successfully compiled to perform as a peer-to-peer networked cryptocurrency as designed.

It's a birthing process. And it's probably about time someone had a word with you about “the birds and the bees” ...

The code contains two protocol assertions: 1) the hash of block 0 is X and 2) the hash of block 0's Merkle tree root is Y. These assertions constrain everyone who joins the network. You can change the hashes but you're then on your own fork, a network of 1 node - unless you run the same code on another connected computer, now you have a network of two nodes and a new blockchain all of your very own.

The hashes are obtained by processing the genesis block transactions into a candidate block, then successfully mining the block, printing out the computed hash values for the block and the Merkle root, then copying those values back into the code so that the assertions are satisfied when the code is recompiled and the client restarted.

The actual code is included below, it's not completely unreadable. The first line binds a string to the variable pszTimestamp. By convention, it is intended to carry date-specific information as a (very weak) guard against pre-mining - no block should have a timestamp earlier than the date referenced in the psztimestamp. The semantics are purely a social convention, it is not enforced in the code. The next three lines are housekeeping for the creation of the transaction object we need. The next three lines fill in the details of the transaction (note the embedding of the pszTimestamp string into block 0 via the genesis transaction) and then the transaction object is hooked into the genesis block object, ready for the next step, the computation of the Merkle root hash and the hooking of the result into the genesis block object. hashPrevBlock is how the chain is formed, the genesis block is unique in having 0 as the value, block 1 will have the genesis block's hash as its prevBlockHash value and block 2 will have block 1's and so on. A chain of blocks. nVersion establishes the versioning protocol, a means of creating distinct separations in the ledger, i.e. hard forks. nTime should be the current time by the developer's watch, nBits is how the starting difficulty is set (expressed in a somewhat oblique idiom of C) and nNonce is used to seed the block hash guesses. All of these values are cryptographically secured in the genesis block by the mining process. They affect the hash computation: change the diff, the hash won't match, same goes for the entire content of the genesis block, ya can't change anything without causing the hash match to fail. That's how the genesis block and the genesis transaction form the secured root of the blockchain. The separate group of lines at the end are the protocol assertions I mentioned earlier.
const char* pszTimestamp = "U.S. News & World Report Jan 28 2016 With His Absence, Trump Dominates Another Debate";
CMutableTransaction txNew;
txNew.vin.resize(1);
txNew.vout.resize(1);
txNew.vin[0].scriptSig = CScript() << 486604799 << CScriptNum(4) << vector((const unsigned char*)pszTimestamp, (const unsigned char*)pszTimestamp + strlen(pszTimestamp));
txNew.vout[0].nValue = 250 * COIN;
txNew.vout[0].scriptPubKey = CScript() << ParseHex("04c10e83b2703ccf322f7dbd62dd5855ac7c10bd055814ce121ba32607d573b8810c02c0582aed0 5b4deb9c4b77b26d92428c61256cd42774babea0a073b2ed0c9") << OP_CHECKSIG;
genesis.vtx.push_back(txNew);
genesis.hashPrevBlock = 0;
genesis.hashMerkleRoot = genesis.BuildMerkleTree();
genesis.nVersion = 1;
genesis.nTime = 1454124731;
genesis.nBits = 0x1e0ffff0;
genesis.nNonce = 2402015;

hashGenesisBlock = genesis.GetHash();
assert(hashGenesisBlock == uint256("0x0000041e482b9b9691d98eefb48473405c0b8ec31b76df3797c74a78680ef818"));
assert(genesis.hashMerkleRoot == uint256("0x1b2ef6e2f28be914103a277377ae7729dcd125dfeb8bf97bd5964ba72b6dc39b"));



Why all this eye-watering detail? Because the actual transfer of the Bee public ledger will be implemented by the programmatic creation of balance->account transactions written to the (nascent) new blockchain's genesis block, following the actual code in sfultong's convenient demonstration.

I include the code here and have styled it to emphasise just the key notions. Ignore the near-invisible beige; the stuff in blue we've already seen (above); the two red variables are the collections of pay-to-pubkey-hash and pay-to-script-hash transactions in the form of paired hash (the address) and amount, as created by the “snapshot” process.

The code works through each entry (orange) in the collections of P2PKH and P2SH entries, creating a P2PKH or P2SH transaction as appropriate with the entry.hash and the entry.amount, adding each one to the collection of genesis block transactions as it goes.

static bool generateGenesis(CBlock& genesis) {
    /**
     * Build the genesis block. Note that the output of the genesis coinbase cannot
     * be spent as it did not originally exist in the database.
     *
     * CBlock(hash=000000000019d6, ver=1, hashPrevBlock=00000000000000, hashMerkleRoot=4a5e1e, nTime=1231006505, nBits=1d00ffff, nNonce=2083236893, vtx=1)

    return true;
}


This is, in essence, the complete approach - balances are transferred by programmatically creating transactions and embedding them in the genesis block. Then, when owners import their privkeys, the wallet (which is a UTXO browser) shows the UTXO balance. Ledger transferred.

I've done a couple of preliminary runs using sqlite for immediacy, one part way, the other complete (except that I inadvertently hit Ctl-C during the final commit, sigh). I've configured it to commit every 10000 records, then if it's interrupted again, it'll just pick up where it left off. I hope to have something for public discussion by the end of this week. By “something for public discussion”, I mean a hefty SQL dump that can be loaded into an RDBMS (PostgreSQL is recommended) and the ledger edited to the community's satifaction.

Sorry for the tedious detail, it's an inevitable consequence of total transparency.

Cheers

the community and graham are still yet to decide the best purpose for them.

Make that just “the community”, I don’t see why I should get to stick my oar in, all I'm doing is valeting the community's new vehicle.

I have not discussed this with graham at all so far but i was thinking we the community should offer graham the same deal soopy had for 1BN for extended help and leadership of beecoin. It is good to have a leader with an incentive to put time and effort into a project. Considering we were willing to pay any amount of bees to get a developer before graham came to help us it seems a win win both ways.

This community has been around long enough to appreciate that in any social group, people come and go all the time. Through fortuitous circumstance, I am currently in a position to make a technical contribution and, at the same time, educate myself in some technical detail that I would otherwise have a bit of a hard time justifying - it also helps a lot that it isn't simply an academic exercise, the result will be of interest to the community.
 
For the moment, I'm happy to provide extended help and leadership (let's be honest here) be an irritating grain of sand around which the community can continue on its path of pearl-building. For the moment. The avatar mugshot is a decade old, I'm now a pensioner caring for a disabled partner whose needs take precedence, literally at the drop of a hat.

I'm neither software engineer nor programmer. What I am is both an artist and a cognitive scientist, my current interest in altcoins is driven by a desire to get a better grip on the socio-political implications of the logical entailments derivable from the ground conditions under which peer-to-peer networked cryptocurrency communities operate. My monograph presenting “A different perspective on cryptocurrency” describes the ground conditions and the basic entailments, once you start unpicking the threads, it gets interesting.

And it genuinely does give me a different perspective. I'd be motivated to keep the 1bn intact in order to pass it on to my successor, intact. Kind of a badge of honorary functionary, a symbol of personal integrity. Useful to have, useful to keep polished. I'm not thinking of next week or even next year but, now that three years have ticked by, what will the picture look like in another five?

Quote
The other 8 BN the community could vote on how to use them or leave them in staking wallets for the longterm funding of the project. Or burn them or any other new ideas that come to peoples minds. As beecoin gains some value those coins can be very useful for developer bounties to bring on more and more devs. PIVx has lots of developers working away for bounties.

I wouldn't underestimate the potential future significance of the group having successfully curated such a substantial community resource. It is an unforgeable testament to a persistently stable group core. That's both the “friendly” and “reliable” boxes ticked. There's quite a lot that can be done with the engine as it stands - which could be a means of priming the dev pump. Development could be split into specification and implementation, just to give people a broader set of opportunities to contribute, either volunteering in order to benefit from experiencing a pro-social context, having “a position” and contributing out of enlightened self-interest, or just plain doin' it for the money.

Cheers

 I checked my wallet and found the necessary transactions. This transaction transfers money from the exchange to my wallet. These wallets belong to allcoin.com: https://chainz.cryptoid.info/bee2/wallet.dws?112.htm

Thanks, I very much hope we can blacklist their wallets they are scammers who stole a lot of my beecoins and ltc.
Do you have any unconfirmed coin output transactions from allcoin to your wallet?
I received some of my coins when the thieves synchronized their wallets (26.12.2016). Then my transactions got into the network and I received coins, which I tried to send from allcoin a year earlier (15.01.2015). Probably thieves noticed the disappearance of coins during the synchronization process and again disabled the wallets from the network. If thieves again synchronize wallets, they again lose part of the stolen coins. This is stupid behavior. They took themselves hostage.

No by the time i heard allcoin was closing i couldn't log in.  I emailed them and they said they had no account under my email address which is curious considering i have the sign up email and all those statements they sent detailing the coins you held there at one time.

They are scammers and just wanted to keep my ltc beecoins and btc their wallets hopefully will be blacklisted these assholes have literally stolen peoples coins.

I have emailed them several times and they said looking into it then stopped replying.

Halorose also observed privately that the Chinese translation for Beecoin actually references Blackcoin (I don't know how to run grep on Chinese characters) and also pointed out that Bee = 蜜蜂 in Chinese.

He has a point. Darkcoin became Dash. It's a much shorter step from BeecoinV2 to Bee (aka 蜜蜂, with all its implications).

If you're going to reinvent, do it from the ground up, otherwise all you're likely to end up with is basically, a new hat.
