    • Open-ethereum-pool migration guides for Tethashv1 mining TEO

      There’s pool operator has problems on migrate their own pool for TEO.

      Here’s open-ethereum-pool based migration to TEO mining.

      please refer here::

      https://github.com/tao-foundation/open-ethpool-teo

      Opensource - ethereum - pool for TEO migration guide.

      1. How to change import path to patched tethashv1

      Download and install gomove binary from https://github.com/KSubedi/gomove

      # you also download gomove binary packages release pages
      # https://github.com/KSubedi/gomove/releases
      
      wget https://github.com/KSubedi/gomove/releases/download/0.2.17/gomove_0.2.17_amd64.deb
      sudo dpkg -i ./gomove_0.2.17_amd64.deb
      
      

      Change go import paths with gomove

      # change import path to followings
      
      gomove -d ./  github.com/ethereum/ethash github.com/tao-foundation/tethashv1
      gomove -d ./  github.com/ethereum/go-ethereum/ github.com/tao-foundation/tethashv1-geth/
      
      

      2. How to upgrade open-ethereum-pool to support parity V2 getWork

      in open-ethereum-pool develop branch there’s parity V2 getWork supports.

      please refer related issues in sammy’s open-ethereum-pool repository

      https://github.com/sammy007/open-ethereum-pool/issues/362

      patched commit is

      https://github.com/sammy007/open-ethereum-pool/commit/34040466e2c392dc8dc6104e571875cbcfbec0c8

      so you can cherry pick or manual patch to your custom open-ethereum-pool src.

      git cherry-pick 34040466e2c392dc8dc6104e571875cbcfbec0c8
      

      and, make all , it is enough things to your open-ethereum-pool to support tethashv1 TEO mining.

      • Public Pool Url will changed

      Current Pool1 will shutdown , when Public pool is spread.
      Pool3 will public pool [teopool].

      and pool2 will public pool [teopool2].

      Another 3rd party pool will be listed on pool main page or github , and this forums.

      • TEO OpenPool Build

      If you migrate to tethashv1 base on open-ethereum-pool ,
      You need to change go-ethereum src link to tethashv1-geth src link.

      It is adapted tethashv1 patched go-ethereum.

      when you porting your open-ethereum-pool change vendor link to https://github.com/tao-foundation/tethashv1-geth

      You can refer open-teo-pool src.

      There’s go reference src changing utils ,

    • [ENG] TEO Status and Notify TEO will Full Public!

      [ENG]

      2018-11-20 08:15:26 +0900 ! ETH Airdrop finished.

      refer here : https://forum.tao.foundation/topic/34/eth-etc-airdrop-finished-successfully

      All ETH/ETC Airdrop funds are about 9.2M TEO spent.

      in case of ETH 3.383 Milion users.
      and ETC 196 Kilo users.

      refer here : https://forum.tao.foundation/topic/31/airdrop-progress

      Average 2~3 TEO is airdroped per accounts. and Max TEO has sent to 511 TEO , which accounts have 2000 ETH (or 66666 ETC) .

      Greater than 2000 ETH (or 66666 ETC) has 0 TEO.

      refer here : https://forum.tao.foundation/topic/24/prepare-teo-mainnet-with-algorithm-change-ethash-tethashv1-and-airdrop-calc

      There’s worry on TEO dumping , cause of Airdroped funds.
      But, We think if TEO price over $10 , then Airdroped funds are may be in market. however , at that time, that’s may be no problem, because it means TEO is more higher potential on cryptocurrency. (I wish TEO will over $10)

      From this time airdrop,
      We have a some effective results and feedbacks from airdroping works.

      1. Excessive TPS Testing on TEO clients.
        Several and continous Max 4066 TX / Block has worked.
        It means Max 330TPS.

      (Running nodes are 11 , But, Block propagation times are not a problem current networks environment, So, No Client nodes are down and run well. Sometimes PC nodes are at lack some seconds)

      In case of Ethereum has average TPS setting is about 20 TPS.

      1. On this time of works, Open-Ethereum-Pool based Pool has some compatibility trouble with Latest RedisDB.

      https://github.com/tao-foundation/open-teo-pool/issues/1

      1. TEthashV1 and TeoMiner stability checked.
        and needs to tune a little bit differently than Legacy ETH-Ethash.
        for stable mining.
        Several information has reported to us.

      Basically TEthashV1 is more multiplication computation on FNV , it makes more secure hash and hashrates are less reporting the hashrates 5~10% compared than legacy ethash.

      Thus, current ETHASH has ETH-ASIC and veiled in accellerations.
      If we assume it as 20%,
      TEO Hashrates are more effective 2~30% values than ethash.

      And Current Open-Ethereum-Pool base Pool displays network hashrates are not exact, in case of more effective Network hashrates values are https://explorer.tao.foundation and TEO Stat will be more accurates.
      It is depend on avg block time and current difficulties.

      1. We are plan to events , collects and share Stock Hashrates per GPU and Tunning value and Tuned hashrates for TethashV1.

      From Above reasons, Early bird miners has some confusion, recheck and review the pools , there’s no big problems.

      Above field experiences gave a great Development information for future.

      1. We are preparing TIP Bountys for During VIP Mainnet , WhiteListed miners, Before Full Public Mainnet starts.

      And, Devide and Branching the Genesis Fund , moved some funds for Burn purpose wallets.

      Feedback from marketing advisors and Early adaptors on cryptocurrency, in future some of burn funds will used for 2nd , 3rd Airdrop and Marketing Events, XRTube (Video Streaming Platform) developments and General Marketing funds.
      In case of Burn funds using cases are feedback from TAO Communities suggestions, for developing and helpful directions for TAO Projects.

      1. Public Bootnode and Open TEO Stat, change the pool to public, foreign Pool listsing… will be progress.

      Completion of Above ETH/ETC airdrop TEO hash about 3.45 Million accounts.

      Please spread this information, and promote TEO to listing exchanges.

    • [KOR] TEO Status and Notify TEO will Full Public!

      [KOR]

      어제 오전 아침 8시 15분 경에 ETH 에어드롭을 완료하였습니다.

      참조 : https://forum.tao.foundation/topic/34/eth-etc-airdrop-finished-successfully

      Airdrop 용 총펀드는 약 920만 TEO 가 ,

      ETH 3.383 백만 유저.

      ETC 19.6 만 유저 에게 지급되었습니다.

      참조 : https://forum.tao.foundation/topic/31/airdrop-progress

      1계정당 평균 , 2~3TEO 지급이 되었고, 최대지급은 2000ETH (또는 66666 ETC) 를 보유한 홀더에게

      약 511TEO 지급되었습니다. 아주 소수 입니다. 물론, 그이상의 지갑은 0 입니다.

      참조 : https://forum.tao.foundation/topic/24/prepare-teo-mainnet-with-algorithm-change-ethash-tethashv1-and-airdrop-calc

      향후, Airdrop 된 펀드가 덤핑요인이 될수있다는 일부 의견이 있는데, 이럴려면 TEO 가 최소 10$ 이상 갔을때나 쪼금 풀릴수있을것이라 보기때문에, 또한, 그 때 쯤이면 도리어 더욱 홀드 할려고 할것이라 봅니다. (그렇게만 , 되면 좋겠습니다)

      이번 Airdrop을 하면서,

      1. 과도하게 TEO 노드의 TPS 및 최대 Transaction 시 노드의 안정성을 시험하기도 하였습니다.

      최대 4066 TX / 블록당 , 최대 330TPS 까지 테스트하는 성과를 올렸습니다. 그것도 연속적으로 테스트 되었습니다.

      (11개의 노드이지만, 블록이 전파시 로드는 같이 걸리기 때문에 뻗는 노드가 발생하는데, 전혀 발생하지는 않았습니다.)

      단, PC 에서 돌리는 노드가 Lack 이 일시적으로 걸리기는 했습니다)

      참고로 ETH 의 현재 TPS 는 현재 설정이 20TPS 입니다.

      이는 과거 2016년 ETH를 괴롭혔던, SPAM Contract DDOS 시의 최대 Transaction보다 많을것입니다.

      1. 이 과정에서 Open-Ethereum-Pool 계열의 문제점을 여럿 확인하였습니다.

      그중, 최신 RedisDB 와 호환성 문제가 발견되었습니다.

      https://github.com/tao-foundation/open-teo-pool/issues/1

      1. TETHASHV1 과 TeoMiner 의 안정성을 검토가 되었습니다.

      또한, 기존 ETH Ethash 와는 다르게 컴퓨팅 연산이 더 들어가게 되므로, 튜닝값도 다르게 설정해야 안정적임이

      여럿 보고 되었습니다.

      또한, 기본적으로 TEthashV1 은 Ethash에 비해서, 좀 더 Secure 하고, 그만큼 추가연산을 하기 때문에 해시값이

      5~10% 낮게 측정됩니다.

      참조 : https://forum.tao.foundation/topic/33/tethashv1-vs-ethash-개략적-설명

      따라서, 현재 ETHASH 의 경우 ETH-Asic 및 ETHash 를 모르게 가속화 하는 비율을 약 20% 추정시에,

      TEO 의 Hash 는 기존 Ethash 계열의 해시값 대비 2~30% 는 추가 해서 비교하면 될것 같습니다.

      또한, Pool 에서 표기되는 네트워크 해시는 정확하지 않고, Explorer.tao.foundation , TEO Stat 에서 표기되는

      평균 블록타임 대비 네트워크해시가 좀 더 정확한 통계값임을 알려드립니다.

      앞으로, GPU 별 해시 , 튜닝 대비 해시값 등을 공모하는 이벤트를 진행하겠습니다.

      1. 이때, 기존 채굴자들의 혼선이 일부 있었지만, 전반적 점검후에 큰 이상상황은 없었습니다.

      위의 문제점들을 확인하는 것은 개발에 있어서 얻은 소득이었습니다.

      VIP Mainnet 동안 , WhiteList 를 신청하고, 엉덩이 무겁게 채굴에 참여해준 마이너에게 추가적인 바운티를 산정하고 완전 퍼블릭전에

      진행하고 있습니다.

      1. Genesis Fund 를 배분하면서, 소각용 펀드로 일부 옮겨 놓았습니다.

      이부분에 대해서 마케팅 자문 및 코인 얼리아답터들의 여럿 자문을 참조하여, 향후 일부는 지속적 2차 , 3차 Airdrop 및

      다양한 이벤트, XRTube 를 위한 플랫폼 개발 및 마케팅 펀드로 활용하는 방안을 검토중입니다.

      이부분은 TAO 커뮤니티에서 지속적으로 의견을 수렴하여 TAO 가 발전할수있는쪽으로 펀드를 사용예정입니다.

      1. 내일 부터는 퍼블릭노드의 부트노드 공개, TEOStat 공개, TEO Pool 의 퍼블릭전환 , 해외의 TEO Pool 리스팅 작업이 진행됩니다.

      현재 위의 ETH/ETC 에어드롭을 통해서, 약 345만 유저가 TEO 유저가 되었습니다.

      주변에 많이 홍보 하여 주시고, 거래소에도 당당히 상장될수있도록 홍보 많이 해주세요.

    • TETHASHv1 vs ETHASH Brief Overview

      **추신 : TEThashV1 과 Ethash 의 차이점은 ,

      추가 : FNV 구체설명 및 EIP-1485 PR추가.

      Ethash Mix 및 DAG 생성단의 FNV Hash 를,

      FNV1A 로 업데이트 하였습니다. (기존은 현재는 depricated 된 FNV0 입니다.)

      ETHASH 블록도는 이더리움 연구회의 https://steemit.com/kr/@dongsamb/ethereum-pow-ethash 참조.

      또한, 일부 기존 ETHASH 에서 Offset 을 초기값으로 사용하는 FNV1A 의 경우 Offset 을 사용하지 않고, FNV1A 라고 주장하는데,

      이는 잘못된 주장입니다.

      FNV1A 의 Offset 은 이미 검증된 PrimeNumber (소수, 암호학에서 가장중요하게 여기는 숫자그룹) 입니다.

      이전단의 Keccak 을 거치고 나오는 값이 Random 넘버라서, Offset 이 필요없다는 주장은,

      일견 맞을듯하지만, 상당한 암호학적 오류가 있습니다.

      이유는, 랜덤넘버가 소수일 확률은 지극히 낮기 때문입니다.

      따라서, 정해진 소수를 정확히 사용하는게 해시 관점에서 보안적으로 더 강하다고 보시면 됩니다.

      이때, TETHASHV1 에서는 원 FNV1A 를 최대한 적용하여, 곱하기 연산이 두번 들어가기 때문에,

      TEthashV1 이 기존 Ethash 보다, 3~10% 정도 해시가 낮게 나오는 현상을 볼수있습니다.

      하지만, ASIC 이나, FPGA 로 갈경우는 위의 곱하기 연산은 CPU 의 기본 계산유닛으로서, 같은 조건에서는 클럭이 높은 CPU 에서 더 효율이 좋다고 보시면 됩니다.

      참고로, CPU 채굴가능한 모네로의 경우 AES (암호화 알고리즘) 이 표준 하드웨어 블록이라서, i 시리즈 CPU 안에 기본 내장되어있어서,

      이를 마이닝프로그램이 활용하면, CPU 로도 상당한 해시가 나오는것을 확인할수있습니다.

      FNV 설명.

      EIP-1485 PR 논의링크 :

      https://ethereum-magicians.org/t/anti-eth-asic-mining-eip-1485-pr/1807

      EIP-1485 PR :

      https://github.com/ethereum/EIPs/blob/7336cceac6c997252299a463ffe896a3414c479b/EIPS/eip-1485.md

      FNV-0 : (depricated)

      hash = 0
       for each byte_of_data to be hashed
       	hash = hash × FNV_prime
       	hash = hash XOR octet_of_data
       return hash
      

      이를 표준 FNV(x,y) 로 C 함수로 구현하면.

      fnv(x,y)   ((x * fnvprime) ^ y)
      

      FNV1A 는

         hash = FNV_offset_basis
         for each byte_of_data to be hashed
         	hash = hash XOR byte_of_data
         	hash = hash × FNV_prime
         return hash
      

      이를 fnv1a(x,y) 일경우, 입력은 4바이트 align 으로 정한다.

      C 로 풀어쓰면,

      fnv1a(x,y)     ( ((offset ^ x ) * fnvprime) ^ y) * fnvprime )
