    Web simulator for my anti-reorg algorithm

    Posted: 25 Nov 2018 07:50 PM PST

    I made a simple web front-end for my Toomim Time anti-reorg algorithm simulator. You can mess with it here:

    http://ml.toom.im:8050/

    It all runs server-side, so if too many people are trying to use it at any given time, it will get slow and buggy. If that happens, you can run a copy locally.

    This algorithm penalizes chains heavily if the first few blocks after the fork were released with a delay after the honest chain, and penalizes the chain lightly if blocks long after the fork were delayed relative to the other chain.

    If the defender chain is shorter than the other, we need to calculate what penalties the defender chain would receive from the blocks that the defender would need to generate in order to catch up. To do this, we add "hypothetical blocks" with the current time. These hypothetical blocks are ignored for calculating the PoW done, but they do contribute to the penalty. The increase in the penalty for the shorter chain over time is the main mechanism by which the algorithm eventually converges to the most-PoW chain.

    Some simplified pseudocode for how the scores are calculated:

    root = last_common_ancestor(chaintip, enemytip) blk = chaintip while blk.pow < opponent.pow: # need to add hypothetical blocks blk = Block(parent=blk, firstseen=opponent.firstseen, tag='-TBD') chain_with_hypotheticals = list_children_to_root(blk, root) for blk in chain_with_hypotheticals: blk.delay = max(0, block.time_received - cousin(block).time_received) blk.penalty = blk.delay / timeconstant / (blk.height - root.height) ** exponent chain_penalty = sum([block.penalty for block in chain_with_hypotheticals]) score = (chaintip.pow - root.pow) / chainpenalty

    Finalization is optional with this algorithm. The sim has finalization disabled by default, but you can put e.g. 10 into the finalization field if you want to see how that affects things. Finalization will only happen if (a) the defender chain is at least n blocks ahead of the attacker chain, and (b) the defender chain has at least 2x the score of the attacker chain at that time.

    The attacker wins if the aqua "Defender hypothetical score" line crosses or touches the attacker's score line.

    The default for the simulation is to emulate an attacker that has 2x as much hashrate as the defense (i.e. can mine blocks every 300 seconds on average), and waits 1 hour before publishing any of the blocks they have mined. This is intended to emulate the scenario in which a malicious actor tries to double-spend an exchange with a 67% hashrate majority. The attacker will give up if he doesn't win within 50 hours. With these settings, the attacker's chain is adopted in about 39.7% of attempts, and most of those attacker victories are fast. The defenders only suffer >=10 block reorgs in 3.3% of all scenarios, and 79.9% of the attacker's blocks are orphaned versus 18.5% of the defender's.

    The attacker can do much better against this algorithm if they only wait 20 minutes before publishing their blocks, but if they do that, the exchanges and businesses that they're trying to double-spend can temporarily suspend deposits and prevent the guerrilla attack from being effective at defrauding the exchanges. Consequently, I decided to default to a 60 minute delay instead. Choosing a 20 minute delay with a 1.5 attacker hashrate also provides some interesting scenarios.

    The full code for the algorithm is here. To install and run locally, use the following commands:

    sudo apt-get install pypy # if you can't get pypy to work on your platform, regular python works too wget https://bootstrap.pypa.io/get-pip.py sudo pypy get-pip.py rm get-pip.py sudo pip install dash sudo pip install dash-html-components sudo pip install dash-core-components sudo pip install dash-table git clone https://github.com/jtoomim/antiReorgSim.git cd antiReorgSim pypy dashreorgsim.py

    You can then view your local instance by pointing a web browser to localhost:8050.

    If you want to test what happens when 10,000 runs with the same configuration are done, edit the params in reorgsim.py and then run pypy reorgsim.py. This may take a while to execute.

    How Long Will Coinbase Withhold BCH Trading Despite Safe Network Conditions?

    Posted: 25 Nov 2018 09:59 PM PST

    Ayyyyyyy

    Posted: 25 Nov 2018 07:00 PM PST

    Of course BCH prices are low - I can't freaking buy BCH off Coinbase. How many hundreds of thousands of dollars to buy BCH has been denied since Coinbase stopped selling BCH?

    BCH and BCHSV withdrawal open now in CoinEx

    Posted: 26 Nov 2018 12:20 AM PST

    Dear CoinEx users:

    After a series of technical evaluation and testing, BCH and BCHSV withdrawal are now available on CoinEx.

    Attention

    Please note that BCH trading pairs now represent BCHABC pairs.

    Reminder

    The prices of BCH and BCHSV may fluctuate drastically after the fork. Please evaluate and invest wisely based on your risk tolerance and financial resources.

    I'm sick of managing multiple BCH wallets & balances & seeds on memo.cash, blockpress.com, yours.org, honest.cash, telescope, etc. To make things easier for adoption, we should allow one BCH balance for all spending, and new apps & services should allow importation of seed words.

    Posted: 25 Nov 2018 05:16 PM PST

    Just look at the disaster with Yours.org. Many people didn't write down their Yours.org seed words, and now they're locked out of their Yours.org BCH balances.

    The path forward should probably be through the Telescope browser add-on or badgerwallet.cash, with seed word importation. Telescope project is currently managed by u/adangert and funded by Bitmain.

    This way, people can maintain one big BCH balance on a hardware wallet (like Ledger), and a smaller "spending" BCH balance on a Bitpay-compatible wallet, like Bitcoin.com wallet.

    Import the Bitcoin.com wallet BCH seed words (BIP39; derivation path m/44/0/0) into Telescope, and people could then operate off of one BCH balance & seed words that they control.

    • Use Bitcoin.com wallet to buy something from a Bitpay-compatible merchant, like NewEgg.com, NameCheap.com, Apmex.com, etc.

    • Use Bitcoin.com wallet on your smartphone to pay your friend for lunch, face-to-face.

    • Use the Telescope browser add-on to click & tip your favorite youtubers & bloggers, wherever they post a BCH address in plain text.

    • Use the Telescope browser add-on to upvote & tip on BCH-based social media sites (like memo.cash, blockpress.com, yours.org, honest.cash, etc). BCH-based sites could give people the option to click their mouse to upvote or tip, and if the Telescope browser add-on sends the right BCH payment, the upvote or tip is registered by the website. With BCH & 0-conf, this should be able to work.

    • Use the Telescope browser add-on to upvote & tip on BCH-based moneybutton-style services (like Gateway.cash). Same as above, with 0-conf.

    • All of the above functions would operate off of one BCH balance & set of seed words, stored only in software wallets (like Bitcoin.com wallet, and Telescope browser add-on wallet), and give users the option to keep their wallets & seed words away from social media websites.

    • If ANY of those above websites or services freeze up or disappear, it's no big deal, because you still have full access to your BCH balance & seed words on your Bitcoin.com wallet.

    • If you need to manage any forked coins (like BSV), you can import the seed words into Electron Cash wallet, split & send coins, etc.

    IMHO, that would make the BCH ecosystem more scalable for normie users.

    At the moment people can no longer access their mnemonic seed on yours. You better not be stealing people their BCH and BSV Ryan. I advice everybody that if you do have your yours seed, so use Electron Cash to move both the SV and BCH connected ASAP. If you don't have the seeds get them.

    IDEA: BCH version of Venmo. Make it easier to send BCH to friends, smartphone-to-smartphone, based on cellphone numbers.

    Posted: 25 Nov 2018 07:22 PM PST

    CoinText.io is great for flip phones in 3rd world countries, but too cumbersome for smartphone users who are used to easy-to-use apps.

    Solution: Venmo for BCH. We'll call it "MoCash" for now. Ideally, integrate this service into existing BCH smartphone wallets (Bitcoin.com wallet, Bitpay wallet, Blockchain.com wallet, Edge wallet, etc). Or it could be a separate app, with seed word importation (so we can do everything from one wallet, BCH balance, and set of seed words).

    The smartphone wallet, or MoCash app, would import Alice's smartphone contacts, and list the phone numbers that have registered with MoCash. If Alice wants to send $1 in BCH to her friend Bob, she just chooses Bob's name & phone number, clicks, sends $1 BCH, and it goes straight to his BCH wallet.

    In addition to looking up via phone number, people could also be registered by email, or username (just like how Venmo operates).

    This would reduce the usage of ugly gibberish BCH addresses.

    And it would be easy to see which of your friends / relatives / coworkers can currently receive BCH, just by looking at your MoCash list of phone numbers & email addresses.

    And unlike CoinText, the service wouldn't need country-specific access numbers or permission from the local cellphone company, since no text messages are sent.

    Just an idea, for any BCH app developers out there.

    Are we done with Significant Protocol Changes on BCH yet? Can we be?

    Posted: 25 Nov 2018 10:43 PM PST

    It may be, to some degree, FUD on the part of SV supporters, but I am getting leery about proposed additional changes to BCH I've heard rumors of, including "Avalanche," "pre-consensus" and possibly even lowering the block time? I'm not talking about minor tweaks, I'm talking about significant changes like that?

    I honestly think the every-six-month planned hardforks are becoming a liability, especially going forward. I understand there may have been a need originally to escape the do-nothingism of Core, but even if BCH has, possibly, seen the end of (considerable involvement from) Craig Wright and nChain, I'm sure it hasn't seen the end of "Craig Wrights." That is, if BCH is successful or promising in the future, there will be more contention, more divisive personalities. It's just inevitable because the community has to get bigger to be a success, by definition.

    People building on BCH have already been divided and spooked enough by this latest controversy. The significant changes to the protocol, especially as enforced by some kind of pre-set deadline need to stop and focus shift to simply keeping the thing running while businesses build and attract customers.

    BCH is supposed to be the business-friendly fork, as typified by willingness to scale on-chain, not the endless protocol-tinkering fork--at least, that's how I understood it. If I'm wrong about the priorities of the current BCH community it may be time to look elsewhere, because I'm interested in a crypto that's focusing on adoption and applications and stability now, not one that is going to be an ongoing science project.

    I understand safe zero-conf is a killer app for BCH, but I also understand that it already pretty much works fine for most everyday purchases. I don't think optimizing too much in advance of perceived, possible, but not actually common threats is necessary or useful; rather, it may hurt more than it helps in terms of the uncertainty and potential for further community division it creates.

    Sorry if this sounds overly negative; I don't mean it as a slam to the devs at ABC or any other team, who I know have been working like crazy to keep things running and who all understand the technical ins and outs way better than I; I'm just concerned.

    Blockstream-esque propaganda campaign in full swing

    Posted: 25 Nov 2018 06:48 PM PST

    ​

    Look at all the nonsense and samefagging going on in the bitcoincashsv sub. I just got banned earlier for calling faketoshi a fraud.

    The intentional misnaming of Bitcoin (BCH) to 'bab' or whatever the fuck that means, and the spreading of misinformation, and character assassinations lead by maybe 3-4 posters.

    This is ridiculous, I sold that garbage scamcoin already but it is obvious to me that Blockstream is supporting their campaign (and obviously fraud exchanges like bitfinex).

    recovery --- lets move on

    Posted: 25 Nov 2018 09:55 PM PST

    i dont see the price, i see the volume which shows the overall activity indicator ,and volumes for BCH are slowly creeping back up to pre - fork levels of around 350 mil per day..

    ​

    all major exchanges have enabled deposits / withdrawls except for shady binance. the hash is stable and strong..

    ​

    ​

    lets get back to work team ! lets start building the superb tools we already have in BCH,

    Ignoring engineers in crypto is the equivalent of ignoring accountants in securities

    Posted: 25 Nov 2018 04:55 PM PST

    The latest narrative I'm seeing from the trolls is that code doesn't matter.

    Yes, it's possible to do "technical analysis" and read the crowd's mood. This works in any market and you can make money. However, in the stock and bond markets, there are real fundamentals behind every asset(which are occasionally overvalued or undervalued by the irrational market).

    There always comes a day of reckoning when Warren Buffet(a value investor) is proved right, because in a falling market, only things with real value can be purchased. Every asset that was purchased based on nothing but it's upward trajectory suddenly has a downward trajectory. Bankrupt companies have nothing stopping them from going to zero. Bankrupt tokens also have nothing stopping them going to zero.

    In 2013, when I first bought Bitcoin, it had a value proposition: Peer-to-peer electronic cash.

    In 2018, the only case being made to new BTC buyers is that the price will go up, or at least that it's a "store of value". Bitcoin has always been a speculative investment, but this is pure speculation. The only thing that will give BTC value in the future is new buyers.

    Today's Core supporters literally have nothing to entice new buyers with other than price speculation. i.e. baseless assertions that a greater fool will come along and buy a useless token for a higher price. Consolidation to a break down proves this assertion is wrong.

    BTC will never see $20k again, because it is now nothing but a ponzi scheme.

    Bitcoin is not a ponzi scheme. Bitcoin is Peer-to-peer electronic cash.

    Because of censorship BTC was hijacked. Because of transparent discussion a hostile miner was shrugged off the bitcoin:cash network. To ensure bitcoin's growth continues unchecked, let's go to on-chain permissionless long-form discussion. Help us finish unite.cash, an on-chain version of reddit.

    Posted: 25 Nov 2018 10:10 AM PST

    The Unite protocol is a powerful, extensible, robust and censorship-resistant social networking and content distribution system.

    Unite-client is simply the first application to implement this protocol. Unite-client relies on Bitcoin Cash and IPFS for attribution, content storage and content delivery.

    It's still early in development some things may crash if too many people try to use it right now, but the demo site is demo.unite.cash

    The best way to help is to contribute dev work with Ty. PM me for his email address. The second best way to help is if someone donates or invests 10k to pay his expenses while finishing development.

    So faketoshi is all excited about some special features that are "only SV" ... and with all of his genius, he can't see how ridiculously futile SV is?

    Posted: 25 Nov 2018 10:30 PM PST

    Big business and big money do not flock to organizations run by mad men.

    If the killer feature he is about to announce/release on SV is really that great... a more trusted coin (like BCH) will adopt "his" technological advancements and leave him in the dust.

    The man is insane.

    No business person would work with him or anything he supports.
