    BTC Bitcoin Cash Stress Test *MEGATHREAD*


    Bitcoin Cash Stress Test *MEGATHREAD*

    Posted: 01 Sep 2018 10:58 AM PDT

    This thread can be used to share updates, resources, questions and everything else related to the Bitcoin Cash stress test commencing today, 9/1/2018.

    WHAT IS THE STRESS TEST?

    "Stress Test day is a community initiative to test Bitcoin Cash and see how it scales and handles large blocks (by filling them with a lot of txns)." -u/BitcoinXio

    The goal is to submit as many transactions as possible to the Bitcoin Cash network to test how it handles high load, identify points of failure, and ready the network for global commerce at scale.

    Read more about it: https://stresstestbitcoin.cash/

    HOW DO I PARTICIPATE?

    Your participation makes the stress test possible! Transactions can be submitted to the Bitcoin Cash network in many ways including sending Bitcoin Cash to yourself or others, using online tip bots, using memo.cash, etc.

    Perhaps the easiest way to participate in the stress test is to use the dedicated tool which can create thousands of transactions: https://www.scale.cash/

    VISUALIZATION TOOLS

    https://mempool2.ratel.money/

    https://txstreet.com/

    https://txhighway.com/

    https://bitcoinsubway.cash/

    https://www.bitlisten.cash/

    (Thank you u/Sk8em! - source)

    UPDATES

    As expected numerous services are under heavy load including the visualization tools, block explorers, and third party APIs. Please share updates as they come in!

    I'm hoping we see a 32MB block today and this becomes a semi-regular test.

    Please set up your full node servers to log performance data for the stress test

    Beware of Heavy Astroturfing

    The largest block so far is 15.2 MBs

    Confirmed: Bitcoin ABC's Amaury Is Claiming They See Themselves As Owners of 'BCH' Ticker No Matter Hashrate (minPoW/UASF Network Split)

    Posted: 01 Sep 2018 06:45 PM PDT

    /u/deadalnix commented:

    "The bch ticker is not stolen by anyone. ABC produced the code and ViaBTC mined it and listed it on its exchange first. nChain can either find a compromise or create their own chain if they do not like bch."


    He goes on further:

    Because abc and viabtc/coinex made it happen, with jonald and a few others. The people who created bch have all beeneattacked by csw and his minions at this point, so it's clear they have no interest in what we've built. It's fine, except the attack part, but if they want something different, they will have to call it something different.

    They are appealing to authority and laying the foundation to take the BCH ticker even if they get minority hash. This is not what Nakamoto Consensus is all about.

    If we abandon Nakamoto Consensus (hash rate decides), then all we have is Proof of Social Media and the bitcoin experiment has fundamentally failed.

    I strongly urge people to support Proof of Work (longest chain, most hash rate keeps the BCH ticker) as this will show it is resilient to social engineering attacks and will fortify us against the coming battles with the main stream establishments.

    Proof:

    Stress Test & Big Blocks: BCH Network Confirms 2M Transactions in 24-Hours - Bitcoin News

    Txhighway was Stress Tested and Upgraded. Thanks Stresstest BCH!

    Posted: 01 Sep 2018 05:37 PM PDT

    It's been an exciting day with Stress Test Bitcoin Cash going on. We're already finding systems and bugs that need fixing. And that includes us at https://txhighway.com

    Last night at the start of Stress Test it became clear many of the bch vs btc visualizers were struggling. Many were using the blockchain.com API which unfortunately appeared to be throttling all connections as the stress test began.

    Tx from http://scale.cash weren't being shown in their API despite the tx hitting the mempool. We're not sure if this was an error on their part or perhaps even political. Either way, it was clear we shouldn't rely on a third party.

    After finishing at the Sydney Bitcoin Cash meetup I got to work rewriting the API to use my new favourite tool Bitbox. (https://developer.bitcoin.com)

    It was a late evening but we're officially back online and the lanes are flooding with our new scale.cash cars, the always fun BTTF DeLorean. 🔥

    Co-creator /u/maplesyrupsucker presented at the Tokyo Bitcoin Cash meetup - watch his talk here.

    Don't forget that donations to txhighway throw lambos down the highway instantly.

    Honoured to be a part of the community and to help Bitcoin Cash scale gracefully. I've never been more confident that Bitcoin Cash is going to become the permissionless money of the world. Thanks to everyone who supported our quirky little project since Dec 2017! It's been a riot. This little project single handedly changed both of our lives. 2018 has been a rodeo! Let's see what the future brings!

    Last year BTC could process a single transaction for $50. Today BCH is processing 35,000 transactions for $50.

    Reminder: Stress Test day goes a full 24 hours

    Posted: 01 Sep 2018 04:32 PM PDT

    Stress Test day goes a full 24 hours, which started from 12:00 UTC Sept 1st (8:00AM EST Saturday to 8AM EST Sunday).

    Keep sending transactions. You can do this with onchain tipping, Memo posts, Yours posts, buying some swag, playing onchain games or with scale.cash tx script.

    Either ATMP or scale.cash is bottlenecking the stress test

    Posted: 01 Sep 2018 07:35 PM PDT

    If you watch transactions as they hit the mempool (e.g. txstreet.com) , you'll notice that they tend to come in large batches, with several minutes elapsing in between batches. I've had scale.cash running and generating transactions during this interval, and noticed that the transactions I generate usually take several minutes before they're visible on block explores or on my local node's mempool. For example, this transaction was generated by my scale.cash webpage about 14 minutes earlier, but when I queried Bitcoin ABC, I see it's not there yet:

    bch@feather:~$ abccli getrawtransaction b639cf06646a01a93f29cbc9b773755158bb712e2e5f3c10978f745e89341a39 error code: -5 error message: No such mempool transaction. ... 

    Ten minutes later, I tried again, and this time it's there:

    bch@feather:~$ abccli getrawtransaction b639cf06646a01a93f29cbc9b773755158bb712e2e5f3c10978f745e89341a39 0200000001c0486ca96c7a8d4f5b1ea68f419ca2c76c1ec3d0613ed11746ead1b4d1addc64000000006a473044022009f68f4c84dd7d94758c49dffb6e4ae28bf74588475352803177cbbe0e0e765c022036f01d76c176a82c645987929cf73cc80d6a3b500f1a79321be4095564431b2141210340a65a40cb472752045abf1a5990d6d85a1d6f71da7dde40dd8b15c179961b1dffffffff02460b0000000000001976a9147a1402392a64f64894296d2528cf907e4b76432488ac0000000000000000186a1673747265737374657374626974636f696e2e6361736800000000 

    So something is bottlenecking transactions in between their generation in javascript in my web browser and the full node network.

    This could just be an issue with scale.cash's webservers. We don't know anything about how those servers work.

    But it could also be the AcceptToMemoryPool bottleneck. Perhaps what is happening is that a large batch of transactions comes in and fills a node's network buffers. Eventually, AcceptToMemoryPool() gets run, locks cs_main and cs_mempool, and runs through all of the transactions. The locking of cs_mempool prevents the networking threads from reading mempool and uploading the transactions to the next peer until this batch of transactions is finished processing. Once that happens, the networking code locks cs_mempool and prevents AcceptToMemoryPool from running, causing the socket reading code to fill its buffers while waiting for ATMP to run again. The process then repeats indefinitely, causing batched broadcasts of transactions instead of smooth trickles.

    Note: I'm not 100% sure that this is how the ATMP code and locks work. I haven't read that section for a while. But it seems likely that the ATMP bottleneck could result in transaction batching. We're getting about 60 tx/sec average, so seems like we're getting close to the expected ATMP bottleneck level of 100 tx/sec average (20 MB/block) that was seen in the Gigablock Testnet Initiative. It's possible that their servers were more consistently powerful than what we have on mainnet, resulting in the ATMP bottleneck being lower.

    Since the start of the stress test, Antpool has mined 192 transactions total.

    A very strong showing during the BCH stress test. Over 60000 transactions handled in a single block, and market price up 15%. Impressive!

    Spent about a total of $50 or so altogether, not all of which is reflected in the test results below. My brothers helped contribute too. Much of the dust that didn't get lost in testing code was contributed to eatBCH :)
