Visa będzie klepać stablecoiny na #ethereum ( ͡º ͜ʖ͡º)

We’ve been advancing and evolving our digital currency strategy for quite some time. Last year we made an investment in Anchorage, a company building security infrastructure for the digital currency ecosystem. Our research team has been exploring the science of blockchain technology for several years. Their work has yielded several promising innovations, including Zether2 and FlyClient.3 Today their research is focused on new mechanisms to improve scalability and enable offline digital currency transactions.

Zether: https://crypto.stanford.edu/~buenz/papers/zether.pdf

We implement Zether as an Ethereum smart contract and show the practicality of our

design by measuring the amount of gas used by the Zether contract. A Zether confidential

transaction costs about 0.014 ETH or approximately $1.51 (as of early Feb, 2019). We

discuss how small changes to Ethereum, which are already being discussed independently

of Zether, would drastically reduce this cost.

@theromanpolan: myślę że adopcja tego typu zacznie się jak zostaną skończone prace nad anonimowym zkrollup

@megaloxantha:

We design a new smart

contract that keeps the account balances encrypted and exposes methods to deposit,

transfer and withdraw funds to/from accounts through cryptographic proofs.

We describe techniques to protect Zether against replay attacks and front-running

situations. We also develop a mechanism to enable interoperability with arbitrary smart

contracts. This helps to make several popular applications like auctions, payment channels,

voting, etc. confidential.

As a part of our protocol,

@theromanpolan: no tak ale to się nie skaluje, to są ciężkie transakcje i nawet po optymalizacji może by było 3TPS (na obecnym), nawet z shardingiem żeby się skalować na skalę visy musisz mieć zkrollup

jest już prototyp bez zkrollup: https://zk.money/zkAsset/zkDai
nad zkrollup z anonimowością pracuje jednocześnie AZTEC i Matter Labs (zksync). Tego brakuje do masowej adopcji przez korporacje.

@megaloxantha: do tego będzie ten klient https://eprint.iacr.org/2019/226.pdf

To validate transactions, cryptocurrencies such as Bitcoin and Ethereum require nodes to verify that

a blockchain is valid. This entails downloading and verifying all blocks, taking hours and requiring

gigabytes of bandwidth and storage. Hence, clients with limited resources cannot verify transactions

independently without trusting full nodes. Bitcoin and Ethereum offer light clients known as simplified

payment verification (SPV) clients, that can verify the
