Double Spend Proof (DSProof) API

https://dsproof.devops.cash is now online and querying the Bitcoin Unlimited getmempoolentry RPC to retrieve Double Spend Proof (DSProof) data.

Looking for feedback from u/BitsenBytes and/or u/ThomasZander on how to test this API as well as any improvements that can/should be made.

Try it yourself:

1. Grab a recent transaction id from the mempool.
2. Then call the API [ https://dsproof.devops.cash/<txid> ]

The best case scenario for any Bitcoin holder is if we get a dollar/satoshi parity - for each $1 USD you get 1 $atoshi. If that happens, an average BTCer will be paying around 25,000 USD per transaction, a BCHer be paying less than 72 USD per transaction. This is how broken BTC is compared to BCH.

Of course we’re comparing apples to apples here: On-chain tx compared to on-chain tx, any non on-chain transaction is inferior and is not part of this comparison by definition.

The very first person to receive Bitcoin from Satoshi himself is ...

Hal Finney!

He is a cryptographer, computer scientist, and contributor to bitcoin received 10 bitcoins from Nakamoto himself – to test the software.

The ABC chain will most likely be split separate times until Coinex suspends withdrawals and deposits and eventually delists.

ABC has rolling 10 block checkpoints which protect exchanges against longer then 10 block reorg. This means an exchange can require 11 confirmations on deposit and be guaranteed not to lose any coins during reorgs. But right now the ABC attacker is not trying to steal coins from coinex by sending it abc buying other coins with them, withdrawing those and then reorg the chain so the attacker gets the abc back.

So how can the attacker annoy coinex?

Simple, start mining towards 10 blocks but don't broadcast any of them. Difficulty will drop some. Wait till the viabtc pool has mined 9 block in a row. Now the very moment the 10th block is broadcasted, broadcast the 10 premined blocks. There is a chance some nodes will follow one chain and some another. The rolling checkpoints now finalize both chains. Coinex would have to spend time in making sure its abc node does not sync to the attackers chain or otherwise the viabtc miners would have mined coins that coinex sees as invalid. Even if a mechanism is found to sync the pool and the exchange nodes, the other abc nodes could get stuck on the attacker chain. Now this can be done multiple times untill electron cash users have only a 25% chance of connecting to a node still on same chain as coinex.

If the attacker automates this process it will require daily manual intervention by everybody running a abc node. Coinex might not be willing to deal with the hassle and would be better of with replacing abc with a abc slp token that runs on bch. Coinex could airdrop this token at 1 abc per 1 bch. And then every ten minutes coinex could mint 6.25 tokens and send 8% of the tokens to abc.

Then abc can not be attacked anymore and the system would as centralised as it is now with the attacker in charge. Abc could still work on something and be paid. It would be as if abc gets assimilated in to the bch simulation and amaury can continue living in ignorance is bliss mode. Coinex can make money with the trading. Win win.

I did it. I emptied my Coinbase account.

Yeah, the title was a little bait and switch, but I did empty my coinbase account. I finally pulled the trigger and took control of my own keys.

I have always been hesitant to maintain full custody of my bitcoin since I wasn't 100% sure I could reliably and responsibly control it. My personal coinbase holdings were from my early days and it has been a relatively small amount. Plus I've just been lazy.

However, with everything going on with Coinbase, and rumors that they will be introducing new policies with the US government regarding self-custody, I am pretty worried they will sanction BTC for all US citizens. Yes, I know it's an extreme case, but as soon as things get real and the current elite realize they have holes in their moneybags (inflation, quantitative easing, stimulus, money printing, bailouts, etc...), they will probably take extreme measures to make sure they retain power.

p.s.

If anyone has or knows someone with mass amounts of venture capital, and wants to bring a better mousetrap to the market, I have a working concept for a hardware wallet that is better than any of the current offerings. I have the manufacturing set up. Just need the money to place the order. I also have experience in manufacturing crypto hardware and software, created the first plug-and-play bitcoin miner, and founded Hands Free Bitcoin. And before anyone starts trolling, yes, my business accounts have always had excessive custodial measures taken to ensure security. My personal coinbase holdings were from my early days and I just haven't taken time to pay much attention to them until now.

Protocol Embedded Staking – A new way of stabilizing crypto tokens

With Proof of Stake (PoS) you have to lock a certain amount of tokens in order to guarantee for the validity of transactions and to support the network. At the end of locking periods users feel an incentive to claim the rewards earned. This leads to a higher probability of tokens being sold on the market, which in turns can lead to some selling pressure and dropping market prices.

Protocol embedded staking was invented in reaction to this disadvantage. It is anchored in the base code of the currency’s smart contract and does not require any explicit control or triggering by the user. Since Protocol Embedded Staking allows complete availability of token usage in DeFi products while earning staking rewards at the same time.

Check out the medium article I found on this topic:

Quite innovative approach I think. Anybody read about this somewhere else?
