Sugarchain
one-CPU-one-vote, the world's fastest PoW blockchain 
https://sugarchain.org




The meaning of Yumekawa
Sugarchain's first node software is called Yumekawa (夢川). It can be translated in some ways.
  • "Yume (夢)" means dream and "Kawa (川)" means river. So it's Dream River in japanese.
  • The second letter "Kawa" stands for "Kawaii (可愛い)". In this case the meaning is Dreamy Cute.
  • Also Yumekawa replaces the word Core (ie: Bitcoin Core). We think it sounds a bit centralized.


Specifications
  • Block time: 5 seconds
  • Difficulty: SugarShield-N510 (based on Zcash's modification of Digishield)
  • Block reward: 42.94967296 SUGAR
  • Halving interval: 12,500,000 Blocks (approx. 2 years)
  • Total supply: 1,073,741,824 SUGAR
  • PoW algorithm: YespowerSugar (based on Yespower 1.0.1)
  • Port: 34230 (RPC 34229)
  • Premine: None (No ICO, No Presale, No Founder's Rewards)


The world's fastest PoW blockchain
  • 5 seconds transaction speed:
    • 120x faster than Bitcoin
    • 30x faster than Litecoin
    • 12x faster than Dogecoin
  • Stable transaction time:
    • Even if the hash power suddenly increases, the block time remains 5 seconds. It is against hash attacks.
  • Don't worry about orphan blocks:
    • According to the testnet results, the average orphan rate is under 3% and no problem occurs.


A better halving
  • Halving is everything:
    • Bitcoin is valuable because its total supply has been strictly limited, unlike traditional currencies.
    • This total supply is controlled only by that halving. There is nothing else.
    • We made this halving better.
  • Block reward:
    • The block reward should be to a power of two, so that it halves correctly.
    • ie) 2^32/100000000 = 42.94967296 SUGAR
  • Halving schedule:
    • Interval 12500000 blocks (5^8*32) which is about 2 years (exactly 1.9818619989852864... years).
    • The total number of times halving will occur is 33 times, over the span of 66 years.
  • Total supply:
    • 1073741824 SUGAR in theory, and 1073741823.875 SUGAR in actual.
    • The difference is 0.125 SUGAR. One Satoshi (0.00000001) limitation makes this difference. In addition, this number is meaningful. FYI: 1 GB = 1073741824 Byte (2^30).
    • The total supply of Sugarchain is about 51 times greater than Bitcoin.
  • Halving Chart:
  • Halving Table:


one-CPU-one-vote
Quote
"31/Oct/2008 Proof-of-work is essentially one-CPU-one-vote"
Satoshi Nakamoto talked about the importance of decentralized mining in his whitepaper. We want to create a blockchain that anyone can do mining easily without any entry barriers.

  • CPU mining only:
    • YespowerSugar (based on Yespower 1.0.1) is only for Sugarchain, not compatible with other Yespower coins.
    • The minimum difficulty (powlimit) is set low enough for two reasons. The first is to handle fast block time; The second is to allow mining on slow CPUs.
  • Mining efficiency:
    • According to the test results, the most efficient is using 8 threads on a single CPU.
    • YespowerSugar is more suitable for older CPUs, because it is essentially a multi-threading resistor. Suitable for smartphones and raspberrypi.
  • NO GPU: GPU mining is not possible.
  • NO ASIC: ASIC mining is not possible.


Other advantages
  • Native segwit (Bech32) address built-in by default: Starting with sugar1q...
  • Fast blockchain synchronization: Using sha256d in header indexing, the initial synchronization speed is as fast as Litecoin


FAQ
  • Disk space requirements:
    • Blockchain size growth is around 10 MB per 1 day and 3.65 GB per year.
  • Network rules:
    • To prevent fraud and timestamp attacks, nodes should be within 70 seconds of accurate internet time, or they will be banned.
  • Selfish mining & time warp attack:
    • Fraud techniques for manipulating timestamps are already known. We use a future time limit (FTL) to prevent this. Blocks that differ 60 seconds or more from the current head will be banned. (credit: zawy12)
  • Exchange listing:
    • We do not have a listing plan at this moment. However, it will be discussed in our community and will be listed in the future. If you have any suggestions for exchange websites, contact us.


Appendix


Wallet


Cpuminer
Bech32 address is by default and strongly recommended. -t1 uses 1 thread. If you want more hash, increase this number.

Been a while since I've actually seen a POW coin introduced with no premine and no ICO. These days most coins are purely ICOs or they got some massive dev premine. Looks promising and hopefully stays CPU mineable only.

Only issue I see is with the short block times and the timestamp cheats. With a very small block reward time of 5 seconds I can see some miners just moving their computers up to 69 seconds and if they got enough hashpower they will find most of the blocks since any block found at the correct time (not t+69 seconds) will get rejected since its not possible for an older block to have a newer block time than a newer block.

Hopefully this is timestamp hack proof.

Someone is trying do premine before launch. Let's be fair! Launching is Friday, 23 August 2019, 15:00:00 (UTC time). We will tell you the node IP on time. Smiley

Hello, this is cryptozeny.

There is one thing to explain. I posted a Sugarchain mainnet launch announcement on bitcointalk.org. A person named cpuminerdev started to claim that (cryptozeny) was the same as wjcloud, the culprit of the Bitcoin Platinum case.

In conclusion, this is not true at all.

wjcloud
A few years ago I only had a phone call with the wjcloud. The call was asked to help the wjcloud develop coin including Ethereum ProgPow hard fork. I refused because I already knew the trueth of wjcloud. Since then, He subsequently came to the community and asked again, but declined each time. I've (cryptozeny) never met wjcloud offline, but according to the testimonies of my friends, the wjcloud is an ordinary Korean high school student. I heard that he recently developed a new coin.

proof
I have all the records for a year (include phone call). I will release it if necessary. If necessary, I will take legal action in South Korea.

Conclusion
I (cryptozeny) is not wjcloud.

Thanks for reading.

cryptozeny aka wjcloud

something I don’t see the connection between one and the second  Roll Eyes

I'm sorry about his abuse. This is all false information. I know him (cpuminerdev) Do not feed the trolls. He is the developer of a coin, and he seems to think that he is in competition with me. I am not.

Hello teenager, you scamming again?

Bitcoin platinum - No premine

Sugarchain - No premine

Scamming people without premine, nice Tongue

Why don't you reveal your identity this time?

Cryptozeny is a 20 yo scammer aka wjcloud, I have proof!

DELAYING MAINNET LAUNCH
Due to someone is trying premine before launching. We have to delay our mainnet launch. The launch date will be announced again. The Genesis block will changed and discard your old wallet. Thank you for your understanding.

Mainnet Delaying:
The mainnet launch was scheduled for 19/08/23 15:00 UTC. But someone () did premineed the chain about 19 hours earlier at 19/08/22 16:22:31 UTC. This is not fair. We decide to delay the mainnet. The Genesis block will change, and the chain he kidnapped means no more. Please remove the downloaded wallet. We will announce the date again after preparation.

How would someone try to premine on your system without any prior permission to do that? I hope it's not as if your security has Ben breached.
Well, if it has, I want to expect that you would have started taking measures to fortify it, so that by the time you reopen, there will not be a problem on that.

You said the coin was perfect but you'be been hijacked, not a very good looking with those FUDs you don't address

claiming to be perfect but someone can hijack their chain even before the launch of their mainnet. lol so how can they convince users that they will not encounter any problem the next time around? if you say you have a perfect system, you should have considered all worst possible scenarios that someone might do to your system...
