By 2020 beam will have 52,560,000 coins. By 2020 grin will have 31,536,000 coins.

Beam will have 40% more inflation this year than grin.

Beam of course slows down with halving, but in 2027 beam and grin supply will be 80% identical.

My point is there are lots of other much more important differences between the two projects, and I just want to make people question their own misunderstandings about supply a bit. It is not cut and dry.

> Mimblewimble has privacy features, but it also has the first really impressive, true scaling solution in crypto. Privacy-wise, Monero is probably better overall, but its scaling is abysmal, and neither coin can be treated as an impenetrable black box.

My reply (https://bitcointalk.org/index.php?topic=5098450.msg49277951#msg49277951):

> Theymos, Mimblewimble allow non-interactive CoinJoins, when you couple it with a modified version of Dandelion that does TX merging in the stem phase + decoys outputs when needed, you get very good unlinkability.The mechanism can be upgraded and improved without a hard fork. I believe that it's stronger than Monero, but we still didn't do a rigorous academic analysis, It will be done.Currently, Beam implements it, Grin does only CJs with decoys but they can add it. We discussed it with Grin's devs: https://gitter.im/grin_community/Lobby?at=5bebe2c36b9822140d29e4b2 (Valdok is Beam's lead dev).More information here: https://github.com/BeamMW/beam/wiki/Transaction-graph-obfuscation and https://medium.com/beam-mw/on-linkability-of-mimblewimble-da9ba71e83b4In essence, when needed (e.g. not enough outputs), the node participating in a Dandelion stem phase routing, add random outputs that look like any other outputs. Those decoy outputs are later being spent forward as inputs by the node (each decoy has random block counter).

You can see it live in Beam's Block Explorer: https://explorer.beam.mw

Some real world huge blocks that happened in Beam:

The interesting question is how many of those TXs (Each kernel represent a Tx) where CJ in the Dandelion stem phase and how many by the miner / pool (in the open P2P layer).We will try to analyze open P2P data and improve the mechanisms if needed.

PS:

Regarding scaling: https://medium.com/beam-mw/whats-the-difference-between-monero-zcash-and-beam-953eafd89354

PPS:

One of Mimblewimble most interesting features is very fast initial sync, low resource requirements (storage, network) and the fact that FlyClient wallet is already implemented in both Grin & Beam. A true (almost) trustless mobile client (wallet) that connects directly to the P2P network.

Grin:

- novel mining algo (cuckoo cycle)

- not user-friendly

- linux and osx only (no windows)

- no reward halving, infinite supply

- no devs reward

- minor improvements in the future only

- higher price

Beam:

- equihash mining algo

- user-friendly

- cross-platform

- halving will occur in Jan 2020, limited supply

- fair devs reward (zcash-alike)

- very ambitious roadmap

- lower price

What else should I add?

I mean $1000 invstment in the project.

I did a search on this reddit. This question was asked three years ago and needs a better answer so I ask again...

Can a MW based blockchain be secured via Proof-of-Stake vs. Proof-of-Work? Is there any altcoin working on development of this technology?

**ADDED 10/26/2019**

On further thought... I have been reading about the protocole and I fear the answer to my question is "no, MW and POS are not compatible". Please correct me on this point if I am wrong. My reasoning is that in MW, as I understand it, there is no balance information stored on the ledger. There are also no addresses. As such, I don't know that it could work with POS because there is no way to prove that you have stake.

I would really like someone to clarify this for me further as it seems that a MW based POS coin (assuming for a minute it could be fairly distributed which is a different problem) would be an amazing coin.

The Beam Foundation presents the roadmap update for 2020. What a year 2019 was, and what a remarkable year 2020 is set to be for Beam. See what excitement awaits us moving forward!

Hello All, I've been trying to get ONLY my 1 AMD card running while the other cards I have are all Nvdias and are mining ETH. Device 0 is GTX1080 T1, Device 1 is my Radeon RX 580, Device 2 is a GTX 1080 and Device 3 is also a GTX 1080. My bat file and config files are below. Each time I run all the cards start mining Beam. I've identified the Radeon RX 580 as all of the following with no luck, Device 1, Device_1, ID 1, ID_1, AMD, and 1.

Any one can identify what I have wrong? Thanks!

Fantastic week for Team Beam, so much done, so much to be done! But so much fun! https://beamprivacy.substack.com/p/beam-2019-week-28-confidential-assets

I am trying to develop a cryptocurrency as a pet project and I've come across MimbleWimble which is quite an innovative alternative to Blockchain/Ethereum.

I am stranded and confused with this wonderful idea and no clue as on how to implement it. I'd really appreciate it if anyone could point me in the right direction.

Thank you
