ROADMAP

"…we see chainhopping as a leap for cryptocurrency in general - the end of chain permanence…"

– JEFF GARZIK, Metronome Chief Designer – via Medium

Metronome is the World’s First Cryptocurrency Allowing Chainhops.

Moving a single cryptocurrency between blockchains – and back.

Portability empowers MET owners to choose the chain where they hold their MET for whatever reason they desire, such as security, fee optimization, and governance arbitrage.

Currently, MET can be ported between Ethereum and Ethereum Classic. Additional chain support is under research and development.

CHAINHOP VALIDATIONS

Three Rollout Phases, Ensuring Zero Supply Violation.

The Validator Network ensures the global supply of Metronome is not violated when chainhopping. There are three phases of Validator network rollout, each phase is increasingly decentralized:

PHASE ONE

Federated Network of Validators.

In Phase 1, federated network of validators operates in a multi-signature, multi-party approach to validate import/export transactions. MET owners may export at any time. For import, a quorum of validators approves a set of import transactions submitted by users. Initially, there are five validators: ETC Labs, the QTUM Team, Bloq, Inc., Veriblock, and Spacechain.

In the event of a chain fork, the quorum of validators will choose which side of a fork is The Real Metronome.

PHASE TWO

Chain Attestors and Stake Weighting.

Phase 2 will decentralize and rely less on validators. For each blockchain, Metronome will look to chain oracles that provide a very specific piece of data: What is the correct chain for a particular currency?

The goal is to automate the choosing of hard fork sides, automatically ingesting and following the community choice for each blockchain.

PHASE THREE

Fully Autonomous, Stake-Weighted Cross Chain Transfers.

Phase 3 of cross-chain validation provides a fully decentralized end state. The model mirrors that of the original Bitcoin blockchain. This is possibly the first cross-blockchain blockchain. Each lily pad — each set of smart contracts — uses a Bitcoin-style consensus protocol, with Proof-of-Stake modification to determine the outcome of hard forks. This consensus protocol automatically chooses one side of a hard fork over another.
