+## Reporting security problems to Solana
+
+**DO NOT CREATE AN ISSUE** to report a security problem. Instead, please send an
+email to security@solana.com and provide your github username so we can add you
+to a new draft security advisory for further discussion.
+
+Expect a response as fast as possible, within one business day at the latest.
+
+<a name="bounty"></a>
+## Security Bug Bounties
+We offer bounties for critical security issues. Please see below for more details.
+
+Loss of Funds:
+$500,000 USD in locked SOL tokens (locked for 12 months)
+* Theft of funds without users signature from any account
+* Theft of funds without users interaction in system, token, stake, vote programs
+* Theft of funds that requires users signature - creating a vote program that drains the delegated stakes.
+
+Consensus/Safety Violations:
+$250,000 USD in locked SOL tokens (locked for 12 months)
+* Consensus safety violation
+* Tricking a validator to accept an optimistic confirmation or rooted slot without a double vote, etc..
+
+Other Attacks:
+ $100,000 USD in locked SOL tokens (locked for 12 months)
+* Protocol liveness attacks,
+* Eclipse attacks,
+* Remote attacks that partition the network,
+
+DoS Attacks:
+$25,000 USD in locked SOL tokens (locked for 12 months)
+* Remote resource exaustion via Non-RPC protocols
+
+RPC DoS/Crashes:
+$5,000 USD in locked SOL tokens (locked for 12 months)
+* RPC attacks
+
+Out of Scope:
+The following components are out of scope for the bounty program
+* Metrics: `/metrics` in the monorepo as well as https://metrics.solana.com
+* Explorer: `/explorer` in the monorepo as well as https://explorer.solana.com
+* Any encrypted credentials, auth tokens, etc. checked into the repo
+* Bugs in dependencies. Please take them upstream!
+* Attacks that require social engineering
+
+Eligibility:
+* The participant submitting the bug report shall follow the process outlined within this document
+* Valid exploits can be eligible even if they are not successfully executed on the cluster
+* Multiple submissions for the same class of exploit are still eligible for compensation, though may be compensated at a lower rate, however these will be assessed on a case-by-case basis
+* Participants must complete KYC and sign the participation agreement here when the registrations are open https://solana.com/validator-registration. Security exploits will still be assessed and open for submission at all times. This needs only be done prior to distribution of tokens.
+
+Payment of Bug Bounties:
+* Payments for eligible bug reports are distributed monthly.
+* Bounties for all bug reports submitted in a given month are paid out in the middle of the
+following month.
+* The SOL/USD conversion rate used for payments is the market price at the end of
+  the last day of the month for the month in which the bug was submitted.
+* The reference for this price is the Closing Price given by Coingecko.com on
+  that date given here:
+  https://www.coingecko.com/en/coins/solana/historical_data/usd#panel
+* For example, for all bugs submitted in March 2021, the SOL/USD price for bug
+  payouts is the Close price on 2021-03-31 of $19.49.  This applies to all bugs
+  submitted in March 2021, to be paid in mid-April 2021.
+* Bug bounties are paid out in
+[stake accounts](https://solana.com/staking) with a
+[lockup](https://docs.solana.com/staking/stake-accounts#lockups)
+expiring 12 months from the last day of the month in which the bug was submitted.
+
+<a name="process"></a>
+## Incident Response Process
+
+In case an incident is discovered or reported, the following process will be
+followed to contain, respond and remediate:
+
+### 1. Establish a new draft security advisory
+In response to an email to security@solana.com, a member of the `solana-labs/admins` group will
+1. Create a new draft security advisory for the incident at https://github.com/solana-labs/solana/security/advisories
+1. Add the reporter's github user and the `solana-labs/security-incident-response` group to the draft security advisory
+1. Create a private fork of the repository (grey button towards the bottom of the page)
+1. Respond to the reporter by email, sharing a link to the draft security advisory
+
+### 2. Triage
+Within the draft security advisory, discuss and determine the severity of the
+issue. If necessary, members of the `solana-labs/security-incident-response`
+group may add other github users to the advisory to assist.
+
+If it is determined that this not a critical network issue then the advisory
+should be closed and if more follow-up is required a normal Solana public github
+issue should be created.
+
+### 3. Prepare Fixes
+For the affected branches, typically all three (edge, beta and stable), prepare
+a fix for the issue and push them to the corresponding branch in the private
+repository associated with the draft security advisory.
+
+There is no CI available in the private repository so you must build from source
+and manually verify fixes.
+
+Code review from the reporter is ideal, as well as from multiple members of the
+core development team.
+
+### 4. Notify Security Group Validators
+Once an ETA is available for the fix, a member of the
+`solana-labs/security-incident-response` group should notify the validators so
+they can prepare for an update using the "Solana Red Alert" notification system.
+
+The teams are all over the world and it's critical to provide actionable
+information at the right time. Don't be the person that wakes everybody up at
+2am when a fix won't be available for hours.
+
+### 5. Ship the patch
+Once the fix is accepted, a member of the
+`solana-labs/security-incident-response` group should prepare a single patch
+file for each affected branch. The commit title for the patch should only
+contain the advisory id, and not disclose any further details about the
+incident.
+
+Copy the patches to https://release.solana.com/ under a subdirectory named after
+the advisory id (example:
+https://release.solana.com/GHSA-hx59-f5g4-jghh/v1.4.patch). Contact a member of
+the `solana-labs/admins` group if you require access to release.solana.com
+
+Using the "Solana Red Alert" channel:
+1. Notify validators that there's an issue and a patch will be provided in X minutes
+2. If X minutes expires and there's no patch, notify of the delay and provide a
+   new ETA
+3. Provide links to patches of https://release.solana.com/ for each affected branch
+
+Validators can be expected to build the patch from source against the latest
+release for the affected branch.
+
+Since the software version will not change after the patch is applied, request
+that each validator notify in the existing channel once they've updated. Manually
+monitor the roll out until a sufficient amount of stake has updated - typically
+at least 33.3% or 66.6% depending on the issue.
+
+### 6. Public Disclosure and Release
+Once the fix has been deployed to the security group validators, the patches from the security
+advisory may be merged into the main source repository. A new official release
+for each affected branch should be shipped and all validators requested to
+upgrade as quickly as possible.
+
+### 7. Security Advisory Bounty Accounting and Cleanup
+
+If this issue is eligible for a bounty, prefix the title of the security
+advisory with one of the following, depending on the severity:
+* `[Bounty Category: Critical: Loss of Funds]`
+* `[Bounty Category: Critical: Loss of Availability]`
+* `[Bounty Category: Critical: DoS]`
+* `[Bounty Category: Critical: Other]`
+* `[Bounty Category: Non-critical]`
+* `[Bounty Category: RPC]`
+
+Confirm with the reporter that they agree with the severity assessment, and
+discuss as required to reach a conclusion.
+
+We currently do not use the Github workflow to publish security advisories.
+Once the issue and fix have been disclosed, and a bounty category is assessed if
+appropriate, the GitHub security advisory is no longer needed and can be closed.
+
+Bounties are currently awarded once a quarter (TODO: link to this process, or
+inline the workflow)

+# Solana AccountsDb Plugin Interface
+
+This crate enables an AccountsDb plugin to be plugged into the Solana Validator runtime to take actions
+at the time of each account update; for example, saving the account state to an external database. The plugin must implement the `AccountsDbPlugin` trait. Please see the detail of the `accountsdb_plugin_interface.rs` for the interface definition.
+
+The plugin should produce a `cdylib` dynamic library, which must expose a `C` function `_create_plugin()` that
+instantiates the implementation of the interface.
+
+The `solana-accountsdb-plugin-postgres` crate provides an example of how to create a plugin which saves the accounts data into an
+external PostgreSQL databases.
+
+More information about Solana is available in the [Solana documentation](https://docs.solana.com/).

+# This file consists of lines of the form:
+#
+#   name = value
+#
+# (The "=" is optional.)  Whitespace may be used.  Comments are introduced with
+# "#" anywhere on a line.  The complete list of parameter names and allowed
+# values can be found in the PostgreSQL documentation.
+#
+# The commented-out settings shown in this file represent the default values.
+# Re-commenting a setting is NOT sufficient to revert it to the default value;
+# you need to reload the server.
+#
+# This file is read on server startup and when the server receives a SIGHUP
+# signal.  If you edit the file on a running system, you have to SIGHUP the
+# server for the changes to take effect, run "pg_ctl reload", or execute
+# "SELECT pg_reload_conf()".  Some parameters, which are marked below,
+# require a server shutdown and restart to take effect.
+#
+# Any parameter can also be given as a command-line option to the server, e.g.,
+# "postgres -c log_connections=on".  Some parameters can be changed at run time
+# with the "SET" SQL command.
