Weekly Shortcuts: Ampleforth,, Grin, IOTA, Hedera Hashgraph

1st February — 7th February

Hello! This is the 4th edition of our weekly overview of various projects, contributing to the bright future of the technology. So, let’s get acquainted with five companies in the spotlight:

Ampleforth is a commodity-money, like Bitcoin or gold, but with near-perfect supply elasticity, like fiat. It is the first sound money with elastic supply. — the pioneering payments and cryptocurrency platform. It offers a seamless mobile wallet app and its prepaid MCO visa prepaid card to be used by people to buy, sell, trade, and spend cryptocurrencies such as Bitcoin and Ethereum, and fiat currencies like dollars, euros and yen.

Grin is a privacy-focused, secure (PoW) and scalable cryptocurrency that supports electronic transactions without censorship and restrictions. Grin proposes a private and lightweight blockchain, based on the Mimblewimble protocol.

IOTA — the first open-source distributed ledger that is being built to power the future of the Internet of Things with feeless microtransactions and data integrity for machines.

Hedera Hashgraph — a decentralized public network where anyone can carve out a piece of cyberspace to transact, play, and socialize in a secure, trusted environment. Hedera is designed for fast, fair, and secure applications to take advantage of the efficiency of hashgraph on a decentralized, public network you can trust.



They explore how these protocols compare to each other, in addition to other prominent Stablecoins.

Also, they analyze AMPL’s volatility in order to determine how effective supply contractions & expansions have been in helping to maintain its price peg. Evidenced in the graph below, AMPL has experienced prolonged periods trading above, below and at its target price.

  1. Grin 2020 Roadmap [core]


  • The IOTA token is now available on Liquid! A leading global platform that provides trading & blockchain-based financial services. As they continue to grow their financial infrastructure, they look forward to enabling future markets in Asia and Japan.
  • March 3rd at 4h45PM GMT+1 in Munich — IOTA will be at CC2020, the European cybersecurity summit! The co-founder, Dominik Schiener, will explain how the Tangle is the trust layer of the digital economy.
  • Chrysalis (Path towards IOTA 1.5) — Chrysalis is separate to the coordicide efforts, and is aimed at improving the usability of the current IOTA mainnet prior to coordicide.


  1. White-flag approach for calculating balances. A simpler, conflict-ignoring approach (valid for the pre-coordicide era) that improves speed and efficiency of tip selection, eliminates certain attacks and significantly reduces the need for reattachments.
  2. New milestone selection algorithm for the coordinator, focused on allowing the network to support as much CTPS as possible, with higher computational efficiency.
  3. New URTS tip selection in node software. Significantly faster and more efficient than the current approach.
  4. Support for a new signature scheme in parallel to WOTS. The network will therefore allow for both quantum resistant one-time signatures and a more commonly used signature scheme allowing re-use of private keys. This will dramatically reduce transaction size, and consequently allow a significant increase in TPS. By introducing a new signature scheme they will also allow for reusable addresses, a very popular request from the community.
  5. Atomic transactions. Move from the current Bundle construct and use simpler atomic transactions instead. This will reduce network overhead, reduce signature verification burden, improve spam protection and congestion control, and reduce length of Merkle proofs (for future sharding). In addition, it will reduce implementation efforts and increase maintainability of their core node software.
  6. Switch to UTXO model from the current balance model. Every coin on an address is then uniquely identifiable and every spend names the exact coins that it wants to move. This allows for faster and more exact conflict handling and improves resilience and security of the protocol. In addition, switching to UTXO will make colored coins on IOTA possible. Combined with Mana (Coordicide) in the near future, this makes for a very attractive tokenization model and will further boost the adoption of the IOTA token.
  7. Switch to an internal binary representation of the trinary transaction. This allows them to work on binary data, for validation, IO and other processing without the need to have many binary-ternary conversions as in the current node software. The bundle hash can still be represented as 243 trits, such that the signing scheme stays the same and no transition of funds is necessary. This should lead to further improvements in performance.

The main features released with this version are:

  1. Autopeering: automatic peer discovery and distance-based neighbor selection
  2. Gossip: network layer for sending and receiving new transactions
  3. Rate control: a temporary non-mana based rate control to limit transaction issuance
  4. API: interface to send data (0 value) transactions and query the Tangle

Hedera Hashgraph

  • DLT Architecture for Media-Attribution Platform — A proposal of an architectural design solution to build the Media-Attribution Platform for open-source communities as well as private organizations while leveraging Distributed Ledger Technology which facilitates a decentralized infrastructure where there is no single authority to dictate or impose outcomes. The proposed architecture uses combinations of powerful DLTs such as Hedera Hashgraph, Hyperledger and Polkadot to resolve the media-attribution problem by ensuring speed, stability, fairness and privacy entailing gold-standard security as the ingrained parameters of the native platform. These attributes of media-attribution platform together enforce, the authenticity and the credibility of the platform which are crucial for attaining network effects.
