Privacy Cryptocurrency Beam Experiences Blockchain Stoppage

Update: Beam has now announced: "The fix was commited on Github. We will be performing additional testing. We will release the binaries in the coming hours. Thanks for your patience."

Its GutHub page puts the error down to a bug involving "Improper block generation upon cut-through of old-new UTXOs."

Newly released privacy-oriented cryptocurrency Beam reported this morning that its blockchain is experiencing technical difficulties.

Beam announced the information on its official Twitter account Monday, saying that its network "Stopped at block 25709" and that it was investigating the matter.

"Issue identified and fix found. Funds are safe. Commit to GitHub in the coming hour. Binaries and detailed Post-mortem later today. Thanks for your patience and stay tuned."

At its January launch, Beam became the first cryptocurrency based on Mimblewimble - a protocol that makes transactions confidential and virtually untraceable.

A "Critical vulnerability" in its wallet software and asked users to uninstall the wallet app immediately and re-download a patched version from their website.

It could have put users' funds at risk by allowing attackers to modify transactions and subsequently send funds directly into their own wallet, Beam's developers said at the time.

Last week, a second privacy cryptocurrency based on Mimblewimble - Grin - also went live.

From cypherpunks, sources told CoinDesk at the time that several VC funds were planning to mine the crypto in advance of its launch.
