According to a recent report, 25 of the 100 total Polygon (MATIC) validators are going to lose their staking status as a result of yesterday’s downtime. Moreover, Polygon’s co-founder claimed that they are considering replacing their whole Boring DAO (BOR) and Heimdall blockchain protocol with a single-blockchain solution.
Multi-Chain Consensus Method
In order to facilitate the growth and interoperability of blockchain networks, Polygon was developed as a blockchain platform and launched. The ultimate goal of the project is to create a blockchain environment that is interoperable with Ethereum and many chains (ETH). It utilizes a proof-of-stake consensus mechanism, similar to Ethereum’s, in order to carry out transactions on the blockchain, which provides it with a high level of security.
Merely recently, when the MATIC team laid off around 20% of its workforce, the Polygon blockchain validator network experienced sync issues, leading to a catastrophic cascade of outages for the bulk of its validators. They were unfortunately forced to resync, which might take up to 12-24 hours. This cascade, according to sources, caused a block explorer outage.
Polygon’s Block Reorg Revelation
Despite the fact that the Polygon team has not yet determined the specific reason why the problem happened, they have discovered a connection to a 157-block reorg that is somehow related to the issue. Their validators are only allowed to reorganize up to 128 blocks at a time at most. It was determined that the reorganization was necessary as a result of issues in the BOR and Heimdall levels of their organization.
The suggestion to begin adopting permissionless validation was made for PIP-4 governance in August of the previous year. In order for a validator to fulfill the standards of the SLA, the plan stipulates that they must get approval from 95% of the median average of the preceding 700 checkpoints. In order to provide the validator with a second opportunity to do the task correctly, the SLA was designed with 700 checkpoints. If that is not the case, we will have to remove them from the stake. After the first period of two months, the SLA would increase from 95% to 98%.
