Any kind of bounty campaign that can earn me tokens.  Smiley Social media, Blog, Translation, etc.

I'm sorry, we don't offer such bounties at the moment.

Are you planning to have a bounty campaign as well? Or do you think you'll sell out without any?
What kind of bounty campaign are you referring to?

Thanks, MiddleFingerToTheMan!

Why on earth would anyone invest if the native token won't accrue value?

Being a particiaption token, DFN gives several privileges:

1. Installing and running smart contract software (playing the role of “gas”)
2. The creation of “mining identities” by making security deposits.
3. The creation of “neurons” (part of the BNS) by making security deposits.
4. The attachment of private cloud networks to the public DFINITY network, again via deposits.

Of course, participation in mining will be rewarded financially.

It's clear that most investors will hope that the token's value will increase. However, we encourage DFN holders to actually use their tokens by contributing to the system. For this purpose, String Labs is working on consumer DFINITY mining & neuron device concepts. See https://dfinity.org/pdf-viewer/pdfs/viewer.html?file=../library/an-intelligent-decentralized-cloud.pdf (page 22).

Ok, please be aware that i'm just playing around here; thinking loudly. Tis is not to be taken too seriously and not aimed at a specific usecase now, but could evolve in that direction.
Thanks for your thoughts!

What if the token can also be seen as a negative thing? Holding a token would be an obligation, not an advantage. A possible scenario could be like this:

The tokens are auctioned off as described, but it's a negative auction: users pay fees not to get the token.

For every block or number of blocks, a token is sent to the account which paid the smallest fees.
I'm not sure if I understand your idea. In Proof of Membership, accounts act as the (second) token. So, how can they be sent to an account and penalize its owner?

(Sorry, I didn't have the time to fully grasp the details of your idea... I may come back later)

I'm not sure if I understand the way how ARK tries to combat centralization risks.

Here's a quote from their article on Medium:
Quote
User Kevin has 20 million tokens. Kevin can nominate his delegate fairly easily. He may even be able to vote in 2 of his own delegates, but rightfully so, he purchased 20 Million tokens. What he can’t do is be guaranteed to nominate more than 8 delegates before his weight is too diluted to maintain his position.
What makes Kevin's weight diluted before he can nominate the next 8 delegates? Can't he just create several accounts and spread his 20 million tokens between them?

I didn't find any clues on that in ARK's whitepaper, just this:
Quote
The 51 forging nodes with the highest number of votes are eligible to Forge ARK
blocks. This design eliminates the possibility that any single large ARK holder or
an organization holding large percentages of ARK are able to gain control over
the entire network by voting for all of their nodes into forging positions, thus
effectively taking complete control over that DPoS Blockchain. Votes from ARK
Tokens held by ARK Crew may be used at ARK Crew's discretion.

So, it still has advantages to have multiple accounts, they are just not as prominent as in other schemes.
Well, that entirely depends on the chosen incentive mechanism. If you opt for the "mine to be released from some duty" model, multiple accounts even become counter-productive. For example, if every member has to perform computional work to stay alive (e.g. by regularly submitting PoW-backed transactions that get included in the blockchain), and by mining a block you get released from that duty, then owning several accounts would result in a multiplication of the required work. In such a setting, it doesn't make any sense to have multiple account since the rewards are calculated based on your total balance, no matter how many accounts you use to store it.

It basically works like Lisks/Arks DPoS system, with specific accounts, which are allowed to contribute to the blockchain (and mint coins in the process). Different to DPoS, who is eligible for minting is determined by a token which differs from the regular coin: If an account holds such a token, it is allowed to mint.
Thanks for the hint. I will take a look at Lisks/Arks DPoS system.

The specifics about how a token is accquired and what "minting" means exactly seems to be up for discussion, although the author gives some ideas, which are quite interesting. Overall, not a bad concept.
Maybe, you can come up with some more ideas/alternative incentive models? Let's have a discussion.  Smiley

This looks like an idea, which looks interesting especially for semi-private blockchains, blockchain-as-a-service solutions and so on.
I think, Proof of Membership could be used with both permissioned (closed) and permissionless models as it only limits the number (creation rate) of accounts, whereas everyone (who can afford to make the highest bid) could become a member.

Re: DECENTRALIZED crypto currency (including Bitcoin) is a delusion (any solutions?)

on 17/04/2017, 18:50:58 UTC
In a recent article I proposed a dual-token approach to blockchain consensus. The system aims to provide economic decentralization, fulfilling the paradigm: One entity, one vote! The model stands in a stark contrast to existing blockchains like Bitcoin, Ethereum or NXT in which the influence of a party is proportional (or even superlinear) to its resources or stake. My proposal can be broken down into the following key points:

- The blockchain makes use of two different tokens: minter accounts and currency units (coins)
- Blocks can only be built by minter accounts
- The creation rate of minter accounts is limited: With every block, only a predefined number of new minters accounts are created.
- Minter accounts can be sold once upon creation, while further sales are strongly discouraged as the seller will still know the private key (and could steal the funds back any time).
- No economic incentive to own multiple accounts

In my second post I relax some of the assumptions made in my seminal article and further explore the design space around Proof of Membership blockchains. The name “Proof of Membership” is chosen to express that every member of the system can contribute to the blockchain, while a member’s impact on the consensus is not based on stake nor on hash rate. Even though it is impossible to physically restrict the number of accounts held by a member, we can make it economically pointless to possess more than one (or maybe a few) account.

This is why Casper tries to punish those that do not follow the rule ; but then this can be gamed too and you get a hopelessly complicated game-theoretical bungle.
How can the punishment mechanism be gamed? Can you describe an attack scenario against it?

If there's nothing at stake (in both senses) with staking, your only stake is that the system works well.  If the random deterministic choice of who can stake, is random enough, then it is also essentially impossible to BRIBE you into staking, because in order to find out WHOM to bribe, you'd need to spend a lot of "proof of work" and chances are you'll find one necessary staker who doesn't accept the bribe.
I'm not sure if I understand your reasoning. Anyone could be bribed to do whatever action (i.e. only build upon certain blocks, censor some kind of transactions/blocks etc.) and without block rewards the bribees would lose nothing (except maybe suffering from a loss of value of their stake due to the attack as such)

I agree with you.  The error in most crypto is the reward, which gives rise to strategies that do not necessarily induce the desired properties.  I also think that the only viable kind of crypto currency is where the validation/consensus decision is taken on a voluntary basis, the "reward" being that the system in which you are invested, keeps running correctly.

However, you still need a kind of deterministic decision *that is hard to game* (because you can do "proof of work" like calculations to get the deterministic solution in your advantage).  This is why a kind of PoS signature scheme is necessary in my opinion.

One alternative incentive scheme might look like this:

- Nodes have to do certain tasks in order to stay alive. In my Proof-of-Membership proposal for example, minting accounts are required to make "heartbeat" transactions every now and then, otherwise the accounts are downgraded and lose their priviledge (interest rate that is paid with every block built by anyone).

- Now, running a node the whole time (or turning it on regularly) will be tedious to most end-users. That's why you can offer them as a block reward the the temporary or permament exemption from their obligation do make heartbeats.

Such a reward mechanism there's no incentive to own multiple accounts as users are trying to get emancipated from hearbeating as soon as possible.

Re: Do you think "iamnotback" really has the" Bitcoin killer"?

The betting stuff enables what Vitalik refers to as "dark uncles" or "dunkles", which Vitalik incorrectly thinks will solve the nothing-at-stake problem.
What makes you think that dunkle inclusion/slashing conditions won't solve NaS?

Also Casper has the problem that all deterministic finality PoS and Byzatine agreement systems have, which is a 33% liveness threshold which if that many validators balk or stop processing, then the chain can't move forward without a hard fork.
I agree with this.

The only way to replace PoW is with an Inverse Commons consensus protocol, which is my new invention.
I'm looking forward to hear more about this and the incentive structure of your protocol.

@iamnotback: This newly released paper might be of interest to you as it suggests an incentive-compatible, race-free block DAG model. The model is claimed to be superior to existing approaches such as GHOST, SPECTRE, Bitcoin-NG, Blockchain-free Cryptocurrencies etc.

Tortoise and Hares Consensus: the Meshcash Framework for Incentive-Compatible, Scalable Cryptocurrencies:
Quote
Meshcash, is designed to be race-free: there is no “race” to generate the next block, hence
honestly-generated blocks are always rewarded. This property, which we define formally as
a game-theoretic notion, turns out to be useful in analyzing rational miners’ behavior: we
prove (using a generalization of the blockchain mining games of Kiayias et al.) that race-free
blockchain protocols are incentive-compatible and satisfy linearity of rewards (i.e., a party
receives rewards proportional to its computational power).

Thanks for your insights iamnotback!

From my deep study of the range of plausible designs for a blockchain consensus system (and I studied much deeper than in than what is contained in that linked thread), I conclude that it is impossible to have a fungible token on a blockchain in which the consensus doesn't become centralized iff the presumption is that the users of the system gain the most value from the system due to its monetary function.

What do you exactly mean by "monetary function"? The fact that miners receive rewards and fees?

However, I was able to outsmart the global elite, because I realized that if the users of the system gained more value from the system for its non-monetary function and iff that value can't be financed (i.e. its value can be leeched off by control of fungible money), and if I provided a way for the users to provide the Byzantine fault DETECTION as a check-and-balance against the power of the whales and if I provided this in a way that is not democracy and is a crab bucket mentality Nash equilibrium, then I would have defeated the problems with the concept of fungible money.

Do you imply that your system (only) offers non-monetary incentives to miners?

I assume you meant "decentralized". But that leaves us with a dilemma:
a) They think it because they are very smart and proved the impossibility of decentralized currencies before releasing Bitcoin. Though that would mean that your design would turn out as impossible as well. Either because it's impossible as such or because it will finally get captured by them.
b) They didn't prove it and just think (or hope) it. In that case they would be very dumb (and thus cannot be called an "elite") since they must have been aware of the risk that someone would eventually come and fix Bitcoin's flaw of becoming centralized.

@iamnotback: Do you have any thoughts on how to solve that dilemma?

Besides the shadow elite are apt to love the altcoin I will launch, because they will see it as yet another speculation that falls under Bitcoin's umbrella.

Why would they love a currency that is designed to be truly decentralized? Please be more specific on that.

Because they don't think anything can be. They will view it as another speculation or if necessary something they can capture when needed.
