The shit project so many people are wasting electricity mining. . . The testnet is still being mined. . . Do not retain and reset to zero later. . . It's not the mainnet
OK! Thanks for your patience and interest. The relaunch is happening. We mined a higher diff genesis block and updated the code with a new port and the new gen-block.
Changes on Github:
1. Updated oBTC Core
2. A new QT-wallet exe file
See oBTC downloads: https://www.powx.org/obtc
If you have the old QT wallet, to get onto the new chain:
1. Please download the new QT wallet
2. After installing it you reset your QT wallet as follows
Settings-> Options-> Reset Options -> OK
After this reset, your wallet will be stored in a new directory and ready to use on the new chain.
If you don't do this your wallet may not sync to the new chain.
The explorer is temporarily at https://explorer.powx.org:8888/ we'll set it back to the standard URL shortly.
Dear miners, your enthusiasm is appreciated. Please note this chain is still experimental and it may be restarted if >1 min blocks are not maintained. Don't be greedy.

Hello mate I think that restart goes well 10 minutes average is reached and personally even if GPU comes I think diff will go up too. Good work
I did some research on oBTC and its Dev team and found out some interesting facts.
It was particularly interesting to find about Dr. Michael Dubrovsky who also happens to be one of Dev team members of "oBTC"
A few things which I found and would like the "oBTC community" to know about are as under:-
Twitter Account of Dr. Michael Dubrovsky - @MikeDubrovsky
Twitter Description - Co-Founder at SiPhox (YC S20) and PoWx. MIT Advanced Study Program Fellow, Technion and several startups prior. From Brooklyn. Recently became dad.
By the way, MIT here is "Massachusetts Institute of Technology"
His personal website is - https://www.michaeldubrovsky.com/
More about Dr. Dubrovsky from Cruchbase:- (https://www.crunchbase.com/person/mike-dubrovsky)
He founded PoWx as a Visiting Researcher at the Technion University Materials Department. Prior to Technion, he founded Simply Grid, a curbside emergency-vehicle charging startup, which was acquired by MOVE Systems. As Director of R&D at MOVE, he led the design and manufacturing of two product lines (for which he holds patents) with complex global supply chains. Michael sees cryptocurrency as a revolutionary improvement in global access to property rights, and is passionate about helping it scale.
More about Siphox (which Dr. Dubrovsky was a co-founder) :-
SiPhox offers a handheld testing device with RNA/DNA and protein testing for point-of-care and At-Home solutions. The company's kit is made by multiplexing RNA, antibody, and antigen tests on a single silicon photonic chip which is amplified by plasmon resonance and silicon photonic resonator readout, enabling users to undertake tests for disease safely and in a disposable point-of-care and at-home manner.
SiPhox was founded in 2020 and is based in Cambridge, Massachusetts, USA.

Most cryptocurrencies rely on Proof-of-Work (PoW) "mining" for resistance to Sybil and double-spending attacks, as well as a mechanism for currency issuance. Hashcash PoW has successfully secured the Bitcoin network since its inception, however, as the network has expanded to take on additional value storage and transaction volume, Bitcoin PoW's heavy reliance on electricity has created scalability issues, environmental concerns, and systemic risks.
Mining efforts have concentrated in areas with low electricity costs, creating single points of failure. Although PoW security properties rely on imposing a trivially verifiable economic cost on miners, there is no fundamental reason for it to consist primarily of electricity cost. The authors propose a novel PoW algorithm, Optical Proof of Work (oPoW), to eliminate energy as the primary cost of mining. Proposed algorithm imposes economic difficulty on the miners, however, the cost is concentrated in hardware (capital expense-CAPEX) rather than electricity (operating expenses-OPEX).
The oPoW scheme involves minimal modifications to Hashcash-like PoW schemes, inheriting safety/security properties from such schemes. Rapid growth and improvement in silicon photonics over the last two decades has led to the commercialization of silicon photonic co-processors (integrated circuits that use photons instead of electrons to perform specialized computing tasks) for low-energy deep learning.
oPoW is optimized for this technology such that miners are incentivized to use specialized, energy-efficient photonics for computation. Beyond providing energy savings, oPoW has the potential to improve network scalability, enable decentralized mining outside of low electricity cost areas, and democratize issuance.
Due to the CAPEX dominance of mining costs, oPoW hashrate will be significantly less sensitive to underlying coin price declines.

All I see in this thread is about people trying to jump onto the mining of "oBTC".
Mining some "oBTC" is fine, but please do remember"PoWx" is a "Non-Profit organization Non-Profit organization dedicated to developing PoW cryptography compatible with ultra-energy efficient optical computing".
..... and what I have mentioned above describes the true credentials of one of the dev team member.
Let us see "oBTC" as a project that can be a real game changer in the may mining hardware gets revolutionized into less energy consuming gadgets.

After reset the wallet, sync done, coins not showing into the wallet only transaction showing but no coins ? what the issue ? 
They reset the chain, and start mining form block 0 All my coin has gone like wind
I stop on this coin ! forerver
bitcoind: chainparams.cpp:104: CMainParams::CMainParams(): Assertion `consensus.hashGenesisBlock == GENESIS_HASH' failed.

Heavyhash.. Reminds me of heavycoin 
- A perfect fair launch with an "Empty Genesis Block" and no "Post Mine"
- A low Block Reward of 50 OBTC per Block, which is a good reward to start
- A very low difficulty to start with
I started mining when the block height was as low as 20 (if I remember) and am getting a very healthy hash rate of 2305 KH/s on my Core i5-2400 CPU @ 3.10 GH........ mining running on 4 Cores (that is the default and you cant change).
That is fine if this is an experimental chain. I will not mind even if the devs re-set the chain.
Atleast, I got to enter the mining at such a lower block height...... and the experience has been wonderful.
a con that I see is the frequent rejections in the shares, possibly that is because of the low block time.
Good Luck, Devs !

Can't beleive that if block mine too fast,dev will reset so how many time this project will be reject?
so how many time this project will be reject?Yep, this is concerning and for sure doesn't help. I have no confidence in this. Cheers

but please rename it correctly, the jumping between bitcoin and obtc is tiring
don't you learn anything? Satoshi is a god and bitcoin is God's creation? how many more restarts will there be? have you heard that there is a testnet for tests? after the third restart you can rename the coin
OK! Thanks for your patience and interest. The relaunch is happening. We mined a higher diff genesis block and updated the code with a new port and the new gen-block.

Dear miners, your enthusiasm is appreciated. Please note this chain is still experimental and it may be restarted if >1 min blocks are not maintained. Don't be greedy.

Dev needs an exchange !!!.
When to restart
so now we must wait ?? months for this project restart again?

I think exactly same thing there already blocks that take 34 minutes to be found and restarting a chain is a mistake. Blockchain anyway will adjust time to 10 minutes average even for that quick blocks mined previously. Of course the situation will re happen because of growing interest. Pool shows that top miners are from China so if you want to restart chan they will force chain at 100% and almost all coins will be in China at 100% be wise and leave chain running early miners are always rewarded with easy blocks and coins that is a normal thing. Let the chain work and do not restart it.
