    Bitcoin Taproot activation megathread

    Taproot activation megathread

    Posted: 04 May 2021 08:33 AM PDT

    A Taproot activation mechanism called "Speedy Trial" has just started on the 1st of May. Its goal is to give miners an opportunity to coordinate a quick activation of the Taproot update.

    The gist of it is: miners are given a three months time period to signal for Taproot activation. Within those three months, there are six sub-phases (each consists of 2016 blocks, aka ~2 weeks). As soon as there are 90% of blocks signalling for Taproot within any of those six sub-phases, Taproot activation will be locked in. The actual new protocol rules will then be enforced starting from block height 709,632, which is expected to be mined in November.

    We are currently in the first second third of those six sub-phases, and Taproot activation will not happen in this one! as miners need time to upgrade their equipment (this is expected, as the software update with Taproot activation mechanism was only released a few days ago). But already now (as of 22th of May) there is roughly ~95% of mining power that has updated and started signalling for Taproot in at least some of their blocks. Keep in mind that 90% of blocks within one difficulty adjustment period (we're currently in the second of six of those periods) need to be signalling. This likely will be achieved when the signalling pools switch from signalling in some of their blocks to signalling permanently.

    A new lock in period started on the 29th of May and it looks like we'll get Taproot locked in this period!

    You can watch the currently signalling blocks/mining pools here (stand: 28th May):

    Currently signalling for Taproot:

    • SlushPool (~3% mining power)
    • AntPool (~18%)
    • F2Pool (~18%)
    • ViaBTC (~11%, signalling in some of their blocks)
    • Huobi (~7%, signalling in some of their blocks)
    • 1THash (~5%, signalling in some of their blocks)
    • Foundry (~4%)
    • Poolin (~12%)
    • BTC.com (~9%, signalling in some of their blocks)
    • SBI Crypto (~1%)
    • EMCDPool (~0.8%, signalling in some of their blocks)
    • Binance (~6%)
    • BTC.top (~4%, signalling in some of their blocks)
    • TMSPool (~0.4%, signalling in some of their blocks)
    • OKExPool (~1%, signalling in some of their blocks)
    • WAYI:CN (~0.4%, signalling in some of ther blocks)
    • SpiderPool (~0.2%)
    • Sigmapool (~0.17%)

    Keep in mind, actual hashrate is always unknown and numbers above are an estimation only, based on observations of the recent blocks, which is always subject to variance.

    What is Taproot?

    Summary

    • If you are a singlesig HODL-only Bitcoin user, Taproot will not affect you positively or negatively. Importantly: Taproot does no harm!

    • If you use or intend to use multisig, Taproot will be a positive for you.

    • If you transact onchain regularly using typical P2PKH/P2WPKH addresses, you get a minor reduction in feerates since multisig users will likely switch to Taproot to get smaller tx sizes, freeing up blockspace for yours.

    • If you are using multiparticipant setups for special systems of trade, Taproot will be a positive for you. Remember: Lightning channels are multipartiicpiant setups for special systems of lightning-fast offchain trades!

    FAQ:

    ELI5 this please?

    There is an update to bitcoin's code, called Taproot. It is good for privacy and efficiency of some important usecases. The update itself (the code) is ready, now it needs to be activated on the network. The developers/users gave the miners three months time to coordinate this activation (the coordination through miners makes it a bit easier, if everyone cooperates).

    That three months time window started on the 1st of May, and this current thread is keeping track of the current activation status. Now we have to wait and see how cooperative the miners will be (most likely they will, but it's not a guarantee).

    If 90% is not reached by August, what then? Is Taproot dead?

    No, if miners are not cooperating, then another activation mechanism will be attempted (probably something similar to UASF in 2017), where full node maintainers simply say "from blockheight x Taproot will be enforced and non-compliant blocks will be rejected", or something similar. The "speedy trial" mechanism was just the least contentious/the fastest one. If it doesn't work, we move on to another mechanism.

    If you are running a node - do you need to take any action now?

    You don't need to, but you could upgrade your client to 0.21.1, which has Taproot activation code included: https://bitcoincore.org/en/2021/05/01/release-0.21.1/

    Taproot is a soft fork, which means it is backwards compatible. Non-updated nodes will be able to stay on the network (and upgrade at their leisure at some point or not), but they won't be able to "understand" what Taproot is (afaik they'll see Taproot transactions as "anyone can spend" transactions, which are still fully valid by the bitcoin rules).

    Will Taproot/Schnorr be helpful for singlesig transactions with multiple inputs/outputs (f.ex coinjoins)?

    No, at least not for now (although any user benefits slightly from reduced fee pressure overall). For those something called "cross-input signature aggregation" is needed. Excellent deep dive: Taproot, CoinJoins, and Cross-Input Signature Aggregation

    How can I check on my own full node how many peers with Taproot compatible nodes are connected to me?

    This command will show you your peers' client version: bitcoin-cli getpeerinfo | grep '.subver' | sort -nk2r | uniq -c

    How can I check on my own full node how many blocks are signalling Taproot in the current activation period?

    The following command line prints the number of blocks in the current retarget period, the number of those blocks which have signaled, and whether it's possible for taproot to activate in this period (assuming there's no reorg):

    bitcoin-cli getblockchaininfo \
    | jq '.softforks.taproot.bip9.statistics | .elapsed,.count,.possible'

    If my bank is so concerned about me losing money investing in bitcoin how come they don't show the same concern for me losing money in online gambling?

    Posted: 31 May 2021 12:57 PM PDT

    Today I received a notice on my banking app about the dangers of investing in bitcoin and cryptocurrencies. Naturally my first thought was "Fuck you, I'll spend my money any way I want". But this got me thinking.

    Online gaming is a big problem. It's highly addictive and destructive and breaks up marriages and families. Addicts often can't pay their bills and mortgages and their children often go hungry as a result of this vice.

    Yet I've never once received a warning from my bank alerting me to the dangers of it. I've also never had any payments to betting / gaming sites stopped or questioned by my bank. I place the odd bet from time to time.

    So how come they are so concerned about me losing money investing in bitcoin when it's been the best performing asset of the last 10 years, outperforming every stock on the planet, whereas gambling almost always results in losing everything? What's their angle?

    India just unbanned Bitcoin (today)

    Posted: 31 May 2021 07:35 AM PDT

    It has come to our attention through media reports that certain banks/ regulated entities have cautioned their customers against dealing in virtual currencies by making a reference to the RBI circular DBR.No.BP.BC.104/08.13.102/2017-18 dated April 06, 2018. Such references to the above circular by banks/ regulated entities are not in order as this circular was set aside by the Hon'ble Supreme Court on March 04, 2020 in the matter of Writ Petition (Civil) No.528 of 2018 (Internet and Mobile Association of India v. Reserve Bank of India). As such, in view of the order of the Hon'ble Supreme Court, the circular is no longer valid from the date of the Supreme Court judgement, and therefore cannot be cited or quoted from.

    At peace with whatever happens

    Posted: 31 May 2021 07:44 PM PDT

    Me and my son started mining in 2013... The butterfly labs systems would heat the entire home up north for every month except January... Still have memories of the constant humming noise... I sold almost everything in 2018 at the bottom due to cancer treatment... Looking forward there is still so much hope. The buzz for the next havening should start around early 2022... The stockpiling is inevitable for what should be a battle for the remaining coins... There will be no second chances at this stage. Nobody will want to part with this rare commodity. So if some unexpected regulations come along there is comfort knowing that this community is battle tested and will not simply roll over for the next so called crisis... We are large enough and strong enough to maintain BTC's value on our own... No worries about the mood swings of wallstreet or political Fuddsters.... Life is good for us believers... Onwards and upwards for the steady hands... Peace and prosperity brothers and sisters... for a better Future!

    RGB for Lightning Network. I'm so excited.

    Posted: 01 Jun 2021 02:12 AM PDT

    "The classic example is CryptoKitties, those breedable NFT felines minted on the Ethereum network. Another perhaps less-familiar example comes from the RarePepe cards issued on Bitcoin using the Counterparty protocol.

    RGB could have a leg up on these forms of NFTs because RGB would allow you to send the computer file for the NFT in the same transaction as the asset that represents it. When you send a CryptoKitty as an ERC-721 token on Ethereum or a RarePepe "colored coin" on Bitcoin, the file for the actual collectible has to be transferred separately. With RGB, both asset and collectible can be "sent inside the same channel," Zucco claimed.

    A more salient use case for RGB, according to Zucco, would come from issuing tether on the protocol. Since all transactions are handled off-chain, Zucco said RGB carries with it the promise to be possibly more private than even the Lightning Network.

    For something like the stablecoin tether, whose on-chain address on blockchains like Bitcoin, Ethereum, EOS and Tron can be easily tracked and, in extreme scenarios, blacklisted, this could bolster tether's privacy and censorship resistance."

    RGB main properties:

    Confidentiality

    Safety

    Scalability

    No bitcoin timechain congestion: transactions keep only homomorphic commitments which require no additional storage

    Future-ready without hardforks

    Higher censorship-resistance than in bitcoin: miners do not see that there is something going on with assets in transactions

    Wow we just broke 3,000,000 members!

    That's really incredible. It's my sincere hope that we can take this moment and highlight the true use case of bitcoin as providing the world's first truly finite digital asset that allows true autonomy and sovereignty for anyone running taking their own private keys and running their own node with SPV (Simple Payment Verification). It's my hope that this post will bring to light the fact that these wallets that allow you to specify your own node are very few and far between (I only know of one on Android for example). Even more concerning is that even the base download for bitcoin core doesn't allow you to run SPV by default as you have to specify peerbloomfilters=1 in the config file.

    Either way bitcoin fam congrats on the big 3MM registered users in this sub! Let's not lose sight of what this is all about! 💪

    RGB protocol explanation for bitcoiners

    Posted: 01 Jun 2021 02:56 AM PDT

    I made a post on yalls where I tried to explain what RGB is and how it works from a high level perspective. I think Bitcoin and LN will be a settlement/payment network for any currency thanks to RGB in the future. To explain RGB, I show how RGB core concepts allows you to take a fresh look at what Bitcoin is technically. This post is for people who want to understand how RGB works under the hund without any code and how it uses Bitcoin and LN, it is quite technical.

    If you want to read my explanation for free, I shared my post in the reddit r/RGB_protocol so you can read it there :) (I hope we will see more activity on the RGB sub with its adoption).

    The LNPBP association also made nice slides recently to illustrate how you transfert RGB asset on-chain here ! This is a great picture to understand how Bitcoin secure RGB transactions and how they happen.

    I hope some of you will enjoy it !

    Visualizing the Snowball of Government Debt

    Posted: 01 Jun 2021 02:36 AM PDT

    "India bans Bitcoin!" Uh, NO. "China bans Bitcoin" Uh, NO. "Nigeria bans Bitcoin" Uh, NO. It's an endless shitstorm as moneyed interests close to the dollar spigot finally see Bitcoin for what it is: A direct threat to monetary expansion and Central bank authority. Put your shields up, and prepare.

    Posted: 31 May 2021 08:28 AM PDT

    I am amazed at how quickly the authorities have "awoken" to the Apex Predator in the room. I have always known why I'm in Bitcoin. For me, it has always been around the following core values:

    Decentralized, with no controlling authority. A finite supply. Freedom from banks and debasement of what I've worked hard to acquire.

    Saifedeen Ammous says without hesitation in "The Bitcoin Standard" that Bitcoin is a direct threat to Central Banks. Many of us have danced around this issue, and tried to downplay where Bitcoin is going. Even Saylor is careful to couch his answer to the repeated question, "Is Bitcoin a threat to currencies and the Central Bank?"

    I used to answer the same question with, "The Central banks, and especially the FED, are too moribund and slow; hell, they can't even understand how--or the how important it is--to implement a CBDC."

    There is no doubt in my mind the authorities are fully awake now, and in attack mode. Latest was Ms. Rowland with the Irish Central Bank just today attacking Bitcoin. She is headed to the EU Central Bank to play a major oversight role. Many here on Reddit have commented on the shitstorm of unprecedented proportions: crime, energy use, investors will lose all their money... .

    All of us are going to have to get a lot tougher. Right now, the Bitcoin community is under attack, and it is not going to let up as adoption and success increase. After this huge correction, which I personally feel was manipulated by many interests, the only way to be successful in the long run with Bitcoin is to "circle the wagons together, and hold the line."
