But thank you for passing on these corrections. This looks much better. I have a few comments that might lend to making this even more accurate or complete. It is nice to see Bitcoin Cash use the proper ticket "BCH" and with clarrification that segregated witness was a softfork (backwards compatible and optional to unupgraded nodes) instead of a hardfork. While segwit might seem to compact more transactions to unupgraded nodes still using the 1 MB blocksize limit (because signature data is stored outside of this legacy 1MB limit), segwit is not actually more compact, but rather is a conservative blocksize increase as a result of the new block space made available through segwit upgrade. (One question I do have, which I am going to ask on the bitcoin-dev mailing list, is "Is the increased blockspace made available through SegWit limited to just witness data?") Segwit is not just about increased blockspace or transaction capactity though, but also has more advantages as a result of seperating the signature into a different segment. More information can be found here https://bitcoincore.org/en/2016/01/26/segwit-benefits/ One advantage is with segwit seperating the signature data, advanced smart contracts and functions on top of bitcoin can be used. This is due to transaction IDs being able to be calculated without signatures, or before being signed. Segwit also increases signature security, and if I am correct enables signatures algorithms to be able to be upgraded via a softfork. Segwit also enables Lightning Network. Lightning Network upgrade to Bitcoin enables instant and really cheap transactions which can handle micropayments and massive scaling of throughput of transactions per second. With micropayment networks such as Lightning Network, payments can be made off-chain, while still being enforced by and settled on the Bitcoin blockchain. The Bitcoin blockchain would act as a settlement or dispute layer. As a result this would also result in freed up space on the bitcoin blockchain as well. The political reasons which differ from the "bitcoin cash" crowd, and the "bitcoin" crowd is the long term vision of how to scale Bitcoin. The majority of the "bitcoin cash" crowd believes that scaling should be done by simply raising the blocksize. The majority of the "bitcoin" crowd, believes that increasing the blocksize to accomodate for all transactions like what "bitcoin cash" is doing, would lead to dangerous centralization of whom would able to operate a Bitcoin node. This is due to the factors of both storage, and bandwidth which are needed to sync and store the blockchain by nodes. https://lightning.network/lightning-network-paper.pdf Paper: The Bitcoin Lightning Network: Scalable Off-Chain Instant Payments DRAFT Version 0.5.9.2 page 2-3 outlines a good description of why increasing the blocksize to accomodate every global transaction as a scaling solution is not feasible. In summary, So while the majority of the bitcoin crowd see micropayment channels and micropayment networks on higher layers as the next step in scaling for handling majority of transactions, the "bitcoin cash" supporters prefer to simply increase the blocksize to handle all these transactions. I plan on reading the rest of this paper to see if I have any other things to add.

To the authors of this paper, I am commenting on Draft NISTIR 8202 Blockchain Technology Overview located at https://csrc.nist.gov/CSRC/media/Publications/nistir/8202/draft/documents/nistir8202-draft.pdf Just in case that document is modified or removed I have also downloaded it to redistribute this error ridden draft at a later point if neccesary, and I also had the Internet Archive save a copy here for sake of archival reasons to give context to this message. https://web.archive.org/web/20180124170359/https://csrc.nist.gov/CSRC/media/Publications/nistir/8202/draft/documents/nistir8202-draft.pdf There are a couple things I would like to contribute on regarding some corrections needed in this paper. I must say, the content in this paper is making me doubt the credibility of the NIST. I am starting to wonder if the NIST is also incompetent with lack of credibility just like with most other government institutions. Falsified information published as truth such as this only expose their ignorance and incompetence and also propagate such ignorance to other institutions and people whom rely on NIST for information or research. The information presented in this paper is technologically invalid and contains false information. I understand that mistakes happen, but this specific section regarding "8.1.2 Bitcoin Cash (BCC)" is obviously written without prior research. Even if research was done no citation is included to back these claims. I ask you to please conduct research and validate information before publishing it, especially when the credibility of the NIST is at stake. I will proceed to outline some corrections. 1. Bitcoin Cash uses the ticker BCH, BCC is the ticker for BitConnectCoin 2. "When SegWit was activated, it caused a hard fork" This is incorrect information. Segwit was not a hardfork. Rather segwit was a softfork meaning that it is backwards compatible with unupgraded nodes and miners. With it being a softfork it actually prevents a fork in the blockchain by still being valid to unupgraded nodes and miners. Because segregated witness is not a hardfork its use is optional. 3. "and all the mining nodes and users who did not want to change started calling the original Bitcoin blockchain Bitcoin Cash (BCC)" The original bitcoin blockchain is still called Bitcoin. Segwit did not create any fork in the blockchain. Bitcoin Cash however was a hard fork that resulted in a forked blockchain and new altcoin. Bitcoin is Bitcoin, Bitcoin Cash is Bitcoin Cash. 4. "Technically, Bitcoin is a fork and Bitcoin Cash is the original blockchain." Technically, that statement is not truth. Bitcoin Cash was forked from the original Bitcoin blockchain to create the altcoin "Bitcoin Cash" (BCH) by people whom believe that the blocksize should be large enough to accomodate all individual transactions on the main chain. Without going into any of my personal opinions of which one is better (bitcoin vs. "bitcoin cash") technically Bitcoin Cash was a hardfork and is not the original chain but a forked one. It is a hardfork as the blocks generated by BCH are incompatible with BTC nodes. Because of this lack of backwards compatibility, and the resulting fork in blockchain is why BCH is technically a hardfork. This is just one section of this paper I have read thus far. It makes me wonder how many other fallacies are throughout this paper. I also wonder how many other NIST papers exist out of draft form that contain errors. Even the smallest amount of research could have prevented this in the case of this paper, unless you are intentionally pushing false information. I hope these comments are of benefit to the improvement of this paper.

These same improvements of which simply increasing the blocksize alone would not fix or enable. Segwit is not just a blocksize increase. Bitcoin Cash, while increasing the blocksize directly, from my understanding has yet to implement the improvements and capabilities that segwit enables. One example being, with transactions hashes being able to be calculated in advanced prior to signing (due to the signature being in different section than that used to calculate the transaction ID) it is possible to create transaction trees, enhanced smart contracts, trustless mixing protocols, micropayment networks, etc... Segwit also increases the security of signatures. There are lots of other things segregated witness enables as well. By saying "..segwit changes alone.... decided to also..." Bitcoin Cash has not implemented segwit. Bitcoin Cash only increased the blocksize. that wording above at least from the way I read it, seems to imply that Bitcoin Cash has segwit. -----BEGIN PGP SIGNATURE----- iQIcBAEBCgAGBQJaeQ3IAAoJEAYDai9lH2mwKkQP/3dgYApq1qv2lGIyZIdeN9SE D5AuXPqFQYAoMwhC0RPNQU/jUisKIyd6zm4XCIm6KPufCtXkjfH9FLhd0ThbCTcy Gk+pYYRBzSuBZdPBKg0DHu7alRETtxbdtUI0zDfERt1FFZb+HmcDcGTfwdVci3fa jBiFXq1R+myMW5xdB44dipSk5kBhcpx2zitr1bIA4rF11QbxKAmzU7iPdRpA+PXz gB9NImc1Dbz+TEA50tdq3v9Ov3x7m7F+QtBnqyLAigJh6XKa6guCfwKIGoawRGwZ v2ur7T+Qh3KGRXCBlHnxgtFte16wHagwvsVgE5EEmJR0yJUc/4XU2kCGANVNDZ/P pphqk8pruQ5rjQ8S+s6i5XG8oHVSB2fDh56NvPY7msA72j+Gk+XneV2eJbEAdjhb 9Ci7u1uPJL3pb3c/ZOwQvpIRV3tRjlh0DertWkd3Li5RZLO3uFvBTxNxrni6+9bf /cmAOwfHjoUp8BX/nvgMjpIDCoEu+Rv9IO/ok3s3mX300JbczAdGbXbsPTE5G+DI RB1kSmszwst8wOlOAsdVqk/iKRJdN9daTGGN6aE/wjkpSg8rW9BOaoI2X9t4oXCU +oe/WlgkxhxPcNyhKpLeeYVe6nFX2fjU+THyyiAq/LJ/qHU/brKpXc4NesCVHhQP BBlxiN0E4gndMGs/Lx89 =+UCK -----END PGP SIGNATURE----- ^ permalink raw reply [flat|nested] 8+ messages in thread

One example being, with transactions hashes being able to be calculated in advanced prior to signing (due to the signature being in different section than that used to calculate the transaction ID) it is possible to create transaction trees, enhanced smart contracts, trustless mixing protocols, micropayment networks, etc... Segwit also increases the security of signatures. There are lots of other things segregated witness enables as well. By saying "..segwit changes alone.... decided to also..." Bitcoin Cash has not implemented segwit. Bitcoin Cash only increased the blocksize. that wording above at least from the way I read it, seems to imply that Bitcoin Cash has segwit. -----BEGIN PGP SIGNATURE----- iQIcBAEBCgAGBQJaeQ3IAAoJEAYDai9lH2mwKkQP/3dgYApq1qv2lGIyZIdeN9SE D5AuXPqFQYAoMwhC0RPNQU/jUisKIyd6zm4XCIm6KPufCtXkjfH9FLhd0ThbCTcy Gk+pYYRBzSuBZdPBKg0DHu7alRETtxbdtUI0zDfERt1FFZb+HmcDcGTfwdVci3fa jBiFXq1R+myMW5xdB44dipSk5kBhcpx2zitr1bIA4rF11QbxKAmzU7iPdRpA+PXz gB9NImc1Dbz+TEA50tdq3v9Ov3x7m7F+QtBnqyLAigJh6XKa6guCfwKIGoawRGwZ v2ur7T+Qh3KGRXCBlHnxgtFte16wHagwvsVgE5EEmJR0yJUc/4XU2kCGANVNDZ/P pphqk8pruQ5rjQ8S+s6i5XG8oHVSB2fDh56NvPY7msA72j+Gk+XneV2eJbEAdjhb 9Ci7u1uPJL3pb3c/ZOwQvpIRV3tRjlh0DertWkd3Li5RZLO3uFvBTxNxrni6+9bf /cmAOwfHjoUp8BX/nvgMjpIDCoEu+Rv9IO/ok3s3mX300JbczAdGbXbsPTE5G+DI RB1kSmszwst8wOlOAsdVqk/iKRJdN9daTGGN6aE/wjkpSg8rW9BOaoI2X9t4oXCU +oe/WlgkxhxPcNyhKpLeeYVe6nFX2fjU+THyyiAq/LJ/qHU/brKpXc4NesCVHhQP BBlxiN0E4gndMGs/Lx89 =+UCK -----END PGP SIGNATURE----- [-- Attachment #2: Type: text/html, Size: 4079 bytes --] ^ permalink raw reply [flat|nested] 8+ messages in thread
