1  Alternate cryptocurrencies / Altcoin Discussion / Prevent PoS users from staking into the past and future? on: October 27, 2021, 07:59:25 AM
I'm interested to know different solutions to prevent people "cheating" on block time in PoS.

PoS generates a hash using various things including time, it is time that limits the hash power of PoS as if you stake too far into the future or past you generate a block that is rejected by the network.  For example the following shows a simplified version of how Peercoin generates a hash to check against the target difficulty. blockFrom.GetBlockTime() is the block time.

Code:
CDataStream ss;
ss << nStakeModifier << blockFrom.GetBlockTime() << nTxPrevOffset << txPrev->nTime << prevout.n << nTimeTx;
uint256 hashProofOfStake = Hash(ss.begin(), ss.end());

When mining you create a block with the current time and see if using it you generate a valid hash. To increase your chances of finding a valid hash you would also try generating blocks up to the past and future block time limits. This poses an advantage over those who do not if this behaviour is not built into the coin itself.

The result of baking this into your code to level the playing field is that the block time will start jumping around and after generating a block you'll likely see several more blocks at once, a new block will change the stake modifier giving all stakers full range of time to stake in again. After the flood of blocks there will be a period to wait while no one was able to generate a block in the next time window and has to wait a second a time on the future time limit. That flood of blocks is normally empty as only the first block was the one that took time to stake.

Networks appear to behave more sanely when "super staking" is not built into the code but this gives an advantage to those who know how to exploit it.

Solutions to this seem to be limiting the future and past time windows.

Does anyone know of any other savvy solutions to this?

This is not a new problem and I'm sure that there must have been attempts to solve this over time.
2  Bitcoin / Development & Technical Discussion / Why not use fixed time instead of median for time in the past for new blocks? on: October 18, 2021, 07:06:40 AM
New blocks that are more than 2 hours ahead of the local time are rejected. For backwards time blocks cannot be less than than the median time of the last eleven blocks. Why not use a fixed time going backwards like the forwards time? The longer we go without a block the larger the backwards time range becomes, a fixed time provides a fixed range from past to future blocks.
3  Alternate cryptocurrencies / Altcoin Discussion / Suggestions for decent crypto marketing on: July 22, 2017, 10:45:40 AM
I am in the process of upgrading a couple of coins from 0.8 to 0.14 with CSV, Segwit and all other bells and whistles. These coins need to gain interest and support on the back of this work if it is to be a success. If no one notices and the coins do not gain use then there is little point in undertaking the work. I've been looking around for someone who does marketing for crypto and can assist with this. If anyone knows of someone or a team that is decent then please respond or send a PM.
4  Alternate cryptocurrencies / Altcoin Discussion / Cannabiscoin Issues Resolved on: July 07, 2017, 02:08:38 PM
I've been trying to get the attention of people on the official thread with no joy. Cannabiscoin Linux clients had an issue which caused them to get stuck, if you run a Cann server on Linux please pull the latest commits and recompile to get the chain syncing again, if you know how to contact someone running a Cann service please let them know.

The market is falling as people have probably noticed the Linux wallets stuck but it's totally unnecessary.

Quick summary of the problem, Windows was not following the checkpoint sync and ended up on a different longer chain, Linux disagreed and stayed on the checkpointed shorter chain. The new commit relaxes the checkpoint sync to allow Linux clients to fully synchronise. The network is still ticking and functional and has been this entire time but Linux has been left out of the party. Once updated they will resume functionality.

No this is not the launch of an alt with Tor, that's been done, but the question is whether anyone knows what the first altcoin with integrated Tor connection?

I'm trying to find the commit history for Tor integration but can only find alts with code dumps as their first commit.

7  Alternate cryptocurrencies / Altcoin Discussion / Wave of attacks on altcoin networks on: June 09, 2017, 09:32:50 AM
I've had a number of people approach me about their coins getting attacked by having the blockchain replaced with a longer chain, the longer chain released by the attacker is without certain transactions. The coin may be attacked but the target is normally an exchange, coins are sent to the exchange, sold for Bitcoin and then withdrawn, at that points the longer chain is released, the coins disappear from the exchange and the attacker gets their coins back. Small coins with low hash power are easy targets for attackers. This has caused a few coin pairs to be frozen and people to be in a panic.

PoW coins are the typical target for this type of attack, PoS coins are harder to target due to PoS block generation but not impossible if PoS generation is still very low. There have been many proposals for solutions to protect coins from a blockchain replacement attacks but for small coins the one solution that works and is available now is to use live checkpointing. Checkpoints are defined in Bitcoin source code by defining a block hash and height, clients will only connect to a chain that has the corresponding blocks, it is to make sure that clients connect to the correct main chain. Altcoins inherit this checkpoint system.

Realtime checkpointing was devised by SunnyKing developer of PeerCoin to protect the chain before PoS was sufficient. It protects the history of the chain by use of a node that will broadcast checkpoints at a certain height set in the conf file. If your coin is being attacked, your coin pair is locked on the exchange and you face potential delisting you may want to consider implementing realtime checkpointing. For reference there is a commit for checkpointing below (Deepcoin linked below was commissioned and not a project that I ran personally), instructions on how to use it is in the checkpointsync.cpp file. If you decide to use this system add a Peercoin copyright notice on the About dialog and COPYING file.

8  Bitcoin / Wallet software / Scalable version of Bitcoin on: April 06, 2017, 09:57:46 AM
What reference implementations of Bitcoin are most suitable for backing a front end service on to with a high user load?

Something that can be put onto our own AWS or Google Cloud hardware and support being scaled up to support high demand. The front end site will allow people to have their own wallet to pay others for work or product discounts or receive funds for those same things.

One options seems to be Bitcore which has come along way since I last used it. It is Node.JS which can be put on AWS Elastic Beanstalk and it uses MongoDB which can also be scaled on AWS. Are there others and please let me know if I'm wrong about Bitcore before I get too entrenched.
9  Alternate cryptocurrencies / Altcoin Discussion / Feathercoin 0.8.7.0 Released - The NeoScrypt Update - Hardfork block 432,000 on: October 13, 2014, 07:38:59 AM
Feathercoin 0.8.7.0 released
The NeoScrypt Update

It has been a long time in the works but we have finally got NeoScrypt and a GPU miner so we can now release the Feathercoin 0.8.7.0 client with NeoScrypt set to replace Scrypt on block 432,000, this should happen on the 26th October 2014. There is a Twitter countdown to the hard fork available here.

NeoScrypt uses stronger components than the Scrypt we are familiar with. A key element of Scrypt is Salsa which adds memory complexity, the problem is that the version of Salsa in Scrypt is weak and has been broken by differential analysis which is why we see cheap and powerful ASICs. NeoScrypt uses a blend of Salsa and its successor Chacha set to a higher level of strength. In theory these two should not be broken for at least a decade, this gives better protection than simply adding hashing functions.

However the goal is not simply to avoid ASICs forever as this may not be possible though ideally we want to stay in reach of as many people as possible without the need for expensive mining equipment. As the majority of people buying Scrypt ASICs are not doing so to mine Feathercoin and the fact that some very large ASIC suppliers will be releasing products soon it seems sensible to move algorithm now before we face the challenges that hit many SHA-256 alts when the SHA-256 ASICs hit. We are moving to a new tier of hashing where Feathercoin can be the leading coin.

Please be aware that after the update your Scrypt mining setup will no longer work. You will need to use the new GPU miner that we have been developing for several months now. Not only do miners need to upgrade their software but pools do as well.

12  Alternate cryptocurrencies / Announcements (Altcoins) / UFO Coin New Team, Client, Future Plans and NeoScrypt on: June 19, 2014, 03:21:24 PM


0.8.8.1 Mandatory Update - Hard Fork on block 266,000

UFO Coin has now hard forked to use the NeoScrypt hashing algorithm to remain in the realm of GPU miners and keep away from ASICs in the near future. NeoScrypt uses very strong elements compared to the current version of Scrypt which is already broken by differential analysis. This affords better protection than blending different hashing solutions together.

Download 0.8.8.1 Wallets and Source


Personal Intro
I thought I would post this here first. I was approached by a couple of dedicated members of UFO Coin to work on their coin. I genuinely like the community members and the coin as I am a fan of the sci-fi genre so I decided to go above and beyond and make the UFO Coin client into a much better, newer and more secure release. It was 0.6 but I have updated them to a 0.8 client with all the bells and whistles and we are hard forking in a couple of weeks’ time to secure the blockchain against attacks. From there we plan to change the hashing algorithm to the newest version of Scrypt called NeoScrypt developed by the excellent Ghostlander. This will use the latest components available and will be a 2014 version of Scrypt, not the very old and broken one used currently. When I say broken I mean by differential analysis which is why we see cheap ASICs coming out without RAM, as it is broken the protection afforded by variable N coins is redundant.
 
The idea these guys have is to fund research like SETI with their UFO Coins. I am all for this sort of thing which is why I was drawn to this project. I have volunteered a fair bit of time to upgrade UFO Coin, I do enjoy helping out other people with their own coins. I believe in the open source ethos which unfortunately is largely overlooked in crypto currency as other coins are seen as competition rather than other projects trying to progress the underlying software.
 
Below is a message that has been created by the whole UFO team and which I am posting here now to officially relaunch UFO Coin. There are ambitious plans for UFO Coin and I am happy to stand with this coin and help it reach its goals.



UFO Coin welcomes Peter Bushnell as lead developer

We’re excited to announce our new UFO coin team members, though grateful for our legacy contributors. The future is looking bright with the addition of Feathercoin creator Peter Bushnell (bushstar) as the new UFO Lead Developer. In just a few short weeks Peter has steered a technical course for UFO coin, securing it from vulnerabilities plaguing most alt coins. Not only are new wallets available and website but we have just moved to a new hashing algorithm NeoScrypt which keeps us in the realm of GPU miners in the years to come.




Technical update

Peter Bushnell (Bushstar) has taken the UFO client which was based in 0.6 and upgraded it to the 0.8.7.0 codebase which is much more stable and feature rich. There are several changes coming that will help secure the blockchain but a hard fork is required to make these improvements.

v0.8.8.1 - Hard fork happened at height 266,000:
  • NeoScrypt - Move to NeoScrypt which uses blended Salsa 20/20 and Chacha 20/20, Blake2s for hashing and FastKDF. Whitepaper available.

v0.8.7.1 - Previous version changes:
  • Nite’s Gravity Well - This allows for rapid response to hash rate changes and recovery from high difficulty
  • Time Warp Manipulability - Will be reduced to the point where its effect is negligible
  • Automatic Checkpointing - This vital feature for any coin prevents transaction roll back via 51% attacks.

New wallet information


The clients made available for PC and Mac have features expected in a new release like Coin Control and the ability to run the client without a wallet attached to reduce the memory requirement. There is the normal elements found in the better made wallets, QR code generation for addresses in the wallet, UPNP and IPv6. The expected network infrastructure is in place with dedicated DNS seeders for clients to use to find others on the network and nodes dedicated for network connectivity.

Exchanges

No exchanges at the moment. Our buddy scificryptoexchange is undergoing an overhaul
We are working our way to reach for new exchanges. They will be coming soon

In the coming days we’ll be announcing many key partners and features through our UFO Community forum. Again, sincere thanks to our members, miners, sponsors and anonymous contributors for their continued dedication to the project, we invite all others to participate your help is always welcome.

As the title says I got a virus warning from Microsoft Security Essentials, this is the native virus protection for Windows 8 and I believe is called Windows Defender. I have not found much on this and presume it is a false positive. Any ideas where this comes from? It is going to spook a lot of new users installing Bitcoin Core. The computer that got this alert is a VM in Oracle VirtualBox running Windows 7 64-bit. It is the 64-bit version of Bitcoin Core.

Good news. The Feathercoin market is back with a major improvements and many bug fixes.  Most noticeable is the built-in escrow system which in my mind makes the market work.

The escrow holds the funds from the buyer until the goods have been received. Once you buy an item you send the funds to the escrow address on the screen. The seller can see that payment has been sent and can send the goods. Once done the buyer can mark the item as received and the funds will be released. For more information on the escrow service please view the escrow FAQ on the market website linked in below.

16  Alternate cryptocurrencies / Altcoin Discussion / Feathercoin - The Miner Update - Hard Fork Block 87948 on: September 24, 2013, 11:24:24 AM
Feathercoin - The Miner Update - Hard Fork Block 87948

The latest Feathercoin version 0.6.4.4 is now available and is a mandatory update. This update includes a hard fork of the block chain to accommodate the changes made in this patch. This hard fork should happen roughly around the 1st October which is only a week away.  To be able to send and receive Feathercoin after block 87948 you have to use the new client. Continuing to use old clients after the hard fork could result in the loss of coins.

Primarily this update is to further the refine of the difficulty adjust. Though the current Feathercoin difficulty which we changed to get us out of a tough spot it is not fair for long term miners who have to experience 41.4% swings on every adjust. The new code will adjust four times more frequently at 126 blocks but to approximately 9% which still gives the exact same overall adjust. To prevent the difficulty from being sent up or down too rapidly the current 504 sample window is being maintained and damping is being introduced to reduce fluctuations between extremes.

There have been long running discussion and arguments on the Feathercoin forum including simulations of various different options surrounding this solution. Feel free to take a look at the latest discussion here.

To get the latest update please go to the Official Feathercoin Website and download the client from the homepage.

Advanced Checkpointing FAQ

What is checkpointing?
Checkpointing was originally built in to Bitcoin in order to prevent dishonest people reversing transactions and taking back the money they had sent. Imagine someone sends you money and you dispatch goods only to find that they have taken the money back out of your account.

The basic checkpointing feature in Bitcoin makes sure that the software only connects to the blockchain defined by the developers. This is a safety feature to stop malicious users from trying to force clients on to a different blockchain. The blockchain has all the Bitcoin transactions of Bitcoin written into it. Every block in the blockchain has a unique string of characters called a hash. In the client the checkpoints are defined by providing the block number and its hash, this is then compiled and distributed. Clients will only accept the blockchain that has the corresponding block number and hash defined in the code. Checkpointing offers some protection against attackers but only up to the last checkpoint. So malicious users could try to orphan blocks after the last checkpoint and reverse transactions with 51% attacks.

What is a 51% attack?
As the network is decentralised the blocks that make it into the blockchain need to be agreed upon by the majority of the miners. So if someone has 51% of the network mining power they are able to dictate which blocks get accepted. Typically a 51% attack is used to force the network to accept alternative blocks to ones that have already made it into the chain. The result of this is to make the transactions in the original blockchain disappear. Typical clients will broadcast the transaction again but the attacker will make sure that their transaction disappears. The aim of this sort of attack is typically to reverse transactions. As these attacks orphan the original blocks, pools and miners also find that the coins they mined disappear. The victims of these attacks are the recipient of the attacker's transaction and the miners whose mined coins from the original blocks will disappear.

What is Advanced Checkpointing?
Advanced Checkpointing allows us to send out checkpoints without having to redistribute the Feathercoin software. This works by having a 'master node' which checkpoints each block it sees on the network protecting it from the attacker. This checkpoint is then picked up by all the other clients on the network which will then ignore any blocks generated by a 51% attack. This protects merchants from transaction reversal and miners from losing their newly minted coins. With Advanced Checkpointing, Feathercoin becomes the most secure of all the Scrypt cryptographic currencies.

Why doesn't Bitcoin or Litecoin have this protection?
51% attacks have generally been theoretical and in the past they have only happened a handful of times to newly born coins. However it appears that the cryptocoin landscape is becoming increasingly hostile as people invest in larger and more expensive mining farms and have access to large mining pools. The attacks that were theoretical are now becoming commonplace to coins which do not have a large amount of hash power.

Bitcoin and Litecoin have never been subjected to successful 51% attacks as their hashpower has so far been too great for the attackers to target. It would seem that as they have not suffered from these attacks then it is not a problem for them but we believe this complacency is the biggest threat. It may be true that Bitcoin is safe for now but all crypto currencies should have some concern for this issue as hash power should never be taken for granted. Litecoin could well find itself subject to such attacks especially as Scrypt hash power is becoming increasingly mobile with the advent of multipools which switch their miner's hashpower to the most profitable coins at the time.

Feathercoin in the past has been subjected to 51% attacks and even though we have enough hash power at the moment to thwart these attacks, that does not mean that the attackers will not have the resources to attack us again in the future. In fact it could be seen as irresponsible if Feathercoin did not come up with some kind of protection against these attacks as our hash power may drop or the attackers may get greater resources.

Is this a centralised solution?
ACP is a form of centralisation that we have put in place because we believe security comes first. Attacks on this new breed of crypto currencies are on the rise with the attackers becoming more and more resourceful. We are the first Scrypt based coin to respond to this threat by recruiting the best minds in this domain to ensure everyone is protected even those who engage in speculative mining and to whom we owe a debt of gratitude for their patience and understanding.

How will Feathercoin continue to innovate to ensure security and decentralisation?
This is the hard work that needs to be done and we will continue to listen to our community and innovate on the design and implementation of the ACP. We believe that Feathercoin should be powered by the community.

This is a form of centralisation as the checkpoint master node is deployed and maintained by the lead developer Peter Bushnell. Currently no other person has access to this system but it is planned to make the checkpointing system distributed over time. Distributing this system would allow several stakeholders like mining pools to have a vote on which block gets checkpointed. The controls in the system are very limited and only allow the developer to change the depth at which the blocks are checkpointed. This is an automated process and there is no facility to pick and choose which blocks get checkpointed.
20  Alternate cryptocurrencies / Altcoin Discussion / [BOUNTY 10BTC] Mining FTC blocks 1BTC@32880,32900,32920,32940,32960 5BTC@33,000 on: May 20, 2013, 11:06:35 AM
Update - After some feedback the bounty has been spread over several blocks to offer rewards for mining right now.

Intro
Feathercoin is now 143 blocks away from a difficulty adjust that sees its new more fine grained difficulty adjust start working. The adjust was initially aimed for one week ahead but as many miners have had to chase the most profitable coins we have seen our hash rate drop. With our current difficulty we are at 50% profitability so the miners we have are the one who think longer term. The Feathercoin team is working on bringing value and services to Feathercoin so you will be able to put your coins to good use.

Bounty
To get the hash rate up I am putting up a bounty of 1BTC for the miner of block 32880,32900,32920,32940 and 32960 and another 5BTC for the miner of block 33,000.

Bonus Bounty - Pledged by Justabitoftime - 5BTC for block 33k if it gets mined by May 25 2013 08:15:15AM (US Eastern Standard Time)

Unless you are a very large miner you will want to mine on a pool. When the block has been mined we will contact the pool owner to find out the user and if we are unable to identify you we will send the bounty, in Feathercoins, to your FTC address registered on the pool, or add the amount to your pool wallet if you do not have a payout address. I have included a list of pools below.

Bounty Blocks Mined
32,880 - 1BTC sent to ra532
32,900 - 1BTC sent to D2 pool
