  • Hmmm. Certificate Transparency project is an interesting development in this area. It seems that there are lots of cool things that can be done with Merkle Trees. MTs are closely related to time stamping, or at least relative time stamping. I am…
  • Okay. I was just wondering, cuz in the brave new world of smart contracts and no trust there isn't necessarily a bonding authority that can either hold your cash against claimants or do a credit check and deem you worth more than your forum nym. I…
  • @giannidalerta I am interested in the concept of "bonding" as it applies to Ethership. Who is the surety provider? How are they to be rated? How does a shipper or consignee collect from a bondsman when the carrier fails in her duty? How does thi…
  • kershy: the OP quote above gives the definition: Recursive Length Prefix (RLP) encoding.
  • The days of unmargined, uncollateralized derivatives passed with Dodd Frank and EMIR post the 2007 financial crisis. The more-or-less universal model is the futures market. You post initial collateral and pay out price changes periodically (daily)…
  • Karl_Schroeder - I do not think you are so far off. Decentralized contracting requires a full rethinking of the "medium scale" law. Principals of fairness, quid pro quo, caveat emptor may remain at the "big scale", and concepts of deposit, rent, t…
  • I am thinking of setting up a legal system in which plaintiffs, defendants and judges are nyms representing Ethereum addresses. We allow both direct addresses (representing secret keys), and contracts (scripts) before the court. Storage on some co…
  • edmundedgar: bravo! Sometimes the crypto-currency community falls into the "give a man a hammer and the whole world looks to him as a nail" syndrome. The blockchain is a magnificent invention, and it opens new vistas of opportunities. But it is n…
  • I agree, aqv99t. I think a testnet is important, and an interactive debugger would be extremely useful, whether at the bytecode or script source level. They really aren't that far apart. It also seems to me that you'd want to start with a robust …
  • From the horse's mouth: Saw this on the Ethereum team's reddit AMA: Q: how do you pull in external data? (eg. weather, EURUSD cross, etc.) A: The data feed source needs to release a signed data feed, and then the contracts will verify the signature …
  • >what seems to be the nexus is trust in dispute mediators... This. How do pseudononymous bots/persons who value their privacy choose a pseudononymous bot/person mediator? Game theory suggests that some mediators are playing the short-con, other…
  • It is not clear to me how contracts can communicate bi-directionally. To begin with, they have an internal stack and storage, a set of inputs that are associated 1-1 with an execution. So nothing comes in that wasn't there when you started executi…
  • The most important thing about the Ethereum model is that the trust model is determined by the users through their choices to write and use individual contracts. Much is made of the incentive to cheat in a pseudononymous-irreversible-transfer model…
  • The whitepaper suggests (a la Mastercoin approach) putting the pubkey of the trusted source on the blockchain. I think my previous suggestion is pretty much identical to this. Also, this would not design RealityKeys out of existence, just allow Eth…
  • Perhaps the Weather Contract has the public key of the trusted source embedded in it. Evaluation consists of checking a piece of data provided to the transaction inputs. If that data is (e.g.) the hash of a statement that it rained in Tokyo on Thu…
