With ERC-1400 Adam Dossa, Pablo Ruiz, Fabian Vogelsteller and Stephane Gosselin have created a new token standard. Unlike the well-known ERC-20 or the two standards ERC-723 and ERC-1155, which are related to CryptoKitties and video games respectively, the focus here is on security tokens.

In the concept presented, the authors present a token that is compatible with ERC-20 or the recently published ERC-777. In addition, it should have various additional features that make it suitable for securities from a regulatory point of view. For example, it should be possible to transfer funds from outside or retrieve lost or stolen assets.

Bitcoin formula: CTOR or the optimum transaction order

Little has happened at Bitcoin formula this week. Apart from a hackathon in Amsterdam announced for the end of October, CTOR attracted attention. This is the Canonical Transaction Ordering Rule, which will come into force with the Bitcoin formula Hard Fork in November. This rule is intended to specify the arrangement of transactions in blocks. Currently, the only requirement is that the transactions are arranged in a causally meaningful manner, i.e. that the inputs and outputs follow each other logically. With CTOR, the transactions are now also sorted alphabetically according to their transaction ID. Only the Coinbase transaction is listed before all others. This is not only readable, but is intended to provide long-term performance improvements for full nodes with shared UTXO records (current account balances, simply put).

Volatility minimization with Abra, new dPOW on Nano and new crypto currency with Mimblewimble
The paper from Cardano is somewhat under the wheels with regard to the distribution of rewards. In this paper, Lars Brünjes et al. present what a fair proof-of-stake system could look like without centralization.

The volatility of crypto currencies is a well-known problem. How, not a few ask, should an alternative monetary system be created if the volatility is too high? One solution is the use of Qubic, IOTA’s smart contract solution. In Abra, the associated programming language, one could implement financial tools that hedge against price fluctuations. In the classical financial market, options are used for this purpose, something similar is suggested in the linked article.

Nano, Maker DAO, MimbleWimble and Bitcoin trader

The distributed proof-of-work system of Nano is to be revised. In principle, Bitcoin trader in the Nano network takes over their proof of work, since everyone maintains their own block chain. For services with high transaction rates such as faucets or tipbots, however, this is uneconomical. Here is the idea that the proof of work can be calculated by others – for a small fee.

In Maker, formerly known as MakerDAO, the so-called Voting Proxy Contract has now been published. The aim of this is that all maker token holders must be significantly shorter online and still be able to participate in the governance. He can now set up a hot wallet solely for the voting, which he then uses as a proxy for his securely stored MKR tokens. In the meantime, there has also been an election about this system, in which the overwhelming majority voted for the basic principles of governance of Maker.

A few months ago we reported on MimbleWimble, a novel protocol focusing on anonymity. Besides Grin, the implementation presented in the linked article, there is also Beam. Unlike Grin, Beam, according to the white paper, sees itself primarily as a store of value and not as a commodity. The Public Testnet was recently released. With the clients downloadable via Github, everyone can now get an idea of this anonymity solution.

Stable Coins, Stable Coins, Stable Coins
The cryptopendant to the apple tree that everyone is supposed to plant before the end of the world is apparently the stable coin. Several efforts for new forms of stable coins made the rounds. The Gemini Dollar and Paxos have already been the subject of an article. Both are ERC-20 tokens on the blockchain, secured by dollars in FDIC-insured bank accounts. It sounds a bit like „Tether on Ethereum“.

In addition to these two stable coins, Ndau has also made a name for himself this week. Ndau is a stable coin, which according to developers relies on a „Blockchain Policy Council“. What one hears so far as information sounds strongly like a delegated proof-of-stake system. You can’t hear any more than that, except that the project promises to be a long-term store of value. All in all, it sounds like a collection of buzzwords.

CarbonUSD go into a little more detail and emphasize that their stable coin based on Hedera
