twitter person @DBCrypt0 defined why Solana was down for nearly 20 hours this weekend.
Solana’s uptime standing confirmed the community suffered an outage that lasted 18 hours and 50 minutes on February 25 – the primary outage in 2023.
Solana has a historical past of community outages, having skilled 11 main outages and three minor outages in 2022. Downtime outages have ranged between 1 hour quarter-hour and 17 hours 7 minutes throughout this era. The newest outage was the longest in over a 12 months.
@DBCrypt0 these failures happen resulting from “an enormous design flawwhich bogs down the system. He additionally defined that validator communications swap to Discord throughout an outage, which contributes to probably lengthy downtime.
Solana’s design flaw
Solana adopts an on-chain consensus mannequin, which signifies that community transactions encompass consensual communication between validators and the transactions themselves, similar to token transfers and minting. This inflates transaction quantity, @DBCrypt0 mentioned.
The graph under exhibits an outline of community transactions. The pink portion of the bar represents precise transactions, whereas the sunshine blue refers to validator verification communications. @DBCrypt0 mentioned “loopy” commit messages accounted for 90%-95% of transactions.
“So when #solana mentions they do 4K TPS simply know that lower than 10% are REAL transactions on the community.
As the vast majority of the buying and selling quantity is made up of messages from the validators, it “bogs the system down”. And when the community goes down, the validators cannot discuss to one another, itsidentifier @DBCrypt0.
In such instances, validators flip to Discord to resolve what to do. The issue is that two-thirds of validators should consent to any proposed motion earlier than it might probably happen, and a few could also be offline and unaware of a failure.
“They then want 66% of the validators I imagine to agree on an answer to stand up.”
Hedera referred to as
Solana”creates insane quantities of information for full nodes” by leveraging an on-chain consensus mannequin, @DBCrypt0 mentioned.
He added that by inflating historical past with pointless commit messages, “an information heart” is required to run a full Solana node.
In conclusion, @DBCrypt0 identified that Hedera additionally runs an on-chain consensus mannequin and suffers from the identical inherent bloat flaw as Solana.
“Sorry to interrupt all of it #HBARbarians however the majority of tx are ineffective
Identical to they’re lit #solana
$HBAR solely does about 3-5 TPS on common.
On February 25, SOL suffered a 9% decline however recovered by closing the subsequent day by day candle above the day past’s open value, indicating that the market accepts Solana breakouts as anticipated conduct.
A Hedera consultant contacted forexcryptozone submit publication to make clear that the community doesn't function an on-chain consensus mechanism. As an alternative, the Hedera Consensus Service "creates decentralized, auditable logs of immutable and timestamped occasions" to trace and log information.
