Weekly market snapshot
This week, Mosaic provided us with data allowing us to compare ETH market cap to daily ERC-20 contract creations. While the average ETH market cap in the month of Dec 2018 was 89% lower than the average ETH market cap in Jan 2018, average ERC-20 contract creations in Dec 2018 were only 28% lower than average ERC-20 contract creations in Jan 2018.
First implementation of MimbleWimble (MW): Beam launch
Beam, a startup based in Israel, launched a privacy-focused cryptocurrency of the same name built on what many have described as the elegant MimbleWimble protocol on Jan 3, 2019. Many in the crypto community have been closely watching the MimbleWimble protocol (published by an anonymous cryptographer in Aug 2016) because it aims to improve upon Bitcoin and privacy coins (i.e. Zcash and Monero):
- Full privacy: In MimbleWimble, all transactions are confidential by default. MimbleWimble uses a cryptographic tool called confidential transactions to achieve this. Confidential transactions keep the transaction amounts visible only to transaction participants (or potentially to additional designated participants) by using something called a blinding factor, a random value that encrypts transaction amounts. MW also combines confidential transactions with CoinJoin, which pools many transactions together to obfuscate which inputs pay which outputs.
- Efficiency: MimbleWimble uses transaction cut-through, so that the system only stores current UTXOs, rather than the blockchain's entire transaction history. This would allow the blockchains built on MimbleWimble to be a fraction of Bitcoin’s blockchain size, when they reach the same scale, making it possible for for a consumer grade device to run a full node.
A blockchain based on MimbleWimble checks that (1) the sum of the inputs equals the sum of outputs, and that (2) transactions don't contain negative amounts to ensure that no transaction is attempting to mint new coins (using bulletproofs, a type of zero knowledge proof). The only transaction type that can mint coins is the coinbase transaction, which is also the only public transaction.
Another important distinction of MimbleWimble is that there are no addresses; there are only inputs and outputs. Sender and receiver wallets have to coordinate and interact to complete a transaction - i.e. communication is synchronous. However, solutions have been discussed that could allow wallets to communicate asynchronously.
The Dandelion protocol (which is separate from MimbleWimble) can be used to further enhance the confidentiality guarantee. Dandelion makes it even more challenging for any node observing the network to create a transaction graph and identify users. It does so by dividing transaction propagation across the network into two phases - the stem phase, where the transaction is sent to a single randomly selected peer, then another, then another, until it reaches the fluff phase, where the transaction is broadcasted to all nodes. Other ways to improve confidentiality (such as attaching dummy UTXOs) have been discussed.
The crypto community will pay close attention to MimbleWimble and the projects that launch on the protocol (i.e. Beam and Grin) as they employ their respective strategies to try to solve challenges that Bitcoin and privacy coins face today and integrate new features following the launch of their mainnet.
